Target should only be 32 bytes copied. - Use a static array for work submission data instead of stack memory. - Clear the buffer data before sprinting to it. - Clear work stratum strings before setting them and add them to debug output. - Drop stratum connect failed message to verbose level only since it's a regular probing message. - TCP Keepalive in curl is only in very recent versions and not required with regular messages on stratum anyway. - Move stratum sockets to curl infrastructure with locking around send+recv to begin support for proxies and ssl. - Make detect stratum fail if a proxy has been set up. - Stratum does not currently have any proxy support so do not try to switch to stratum if a proxy has been specified. -

Use 5 second timeout on sock full for now as a temporary workaround. - If no stratum url is set by the end of the detect stratum routine, copy the sockaddr url. - Make all buffers slightly larger to prevent overflow. -

Also remove old work_restart timing. - Check for gpu return times of >= 0, not just 0, to fix intensity dropping to -10. - Restart is zeroed in the mining thread so no need to do it inside the bitforce code. - More improvements to comms. BFL return nothing when throttling, so should not be considered an error. Instead repeat with a longer delay. - Polling every 10ms there's not much point checking the pthread_cond_timedwait as it just adds overhead. Simply check the value of work_restart in the bfl main polling loop. - Use a pthread conditional that is broadcast whenever work restarts are required. Create a generic wait function waiting a specified time on that conditional that returns if the condition is met or a specified time passed to it has elapsed. Use this to do smarter polling in bitforce to abort work, queue more work, and check for results to minimise time spent working needlessly. - Add busy time to wait time. - api.c put version up to 1.14 - Add tiny delay after writing to BFL Change BFL errors to something more human readable Send work busy re-tries after 10ms delay - Fix race condition in thread creation that could under some conditions crash BFGMiner at startup BFGMiner Version 2.4.4 - July 1, 2012 - Fix builds on non gnu platforms. - api.c ensure old mode is always available when not using --api-groups + quit() on param errors - Implement rudimentary X-Mining-Hashrate support. - Detect large swings in temperature when below the target temperature range and change fan by amounts dependant on the value of tdiff. - Adjust the fanspeed by the magnitude of the temperature difference when in the optimal range. - Revert "Restarting cgminer from within after ADL has been corrupted only leads to a crash.

Do this by turning the rolltime bool into an integer set to the expiry time. If the pool supports rolltime but not expiry= then set the expiry time to the standard scantime. - When disabling fanspeed monitoring on adl failure, remove any twin GPU association.

Display a warning only and disable fanspeed monitoring. - Icarus: fix abort calculation/allow user specified abort - Icarus: make --icarus-timing hidden and document it in FPGA-README - Icarus: high accuracy timing and other bitstream speed support - add-MIPSEB-to-icarus-for-BIG_ENDIAN - work_decode only needs swab32 on midstate under BIG ENDIAN - add compile command to api-example.c - save config bugfix: writing an extra ',' when no gpus - Add dpkg-source commits BFGMiner Version 2.4.1 - May 6, 2012 - Icarus: Calibrate hashrate yet even more accurately - In the unlikely event of finding a block, display the block solved count with the pool it came from for auditing. - Display the device summary on exit even if a device has been disabled. - Use correct pool enabled enums in api.c. - Import Debian packaging configs - Ensure we test for a pool recovering from idle so long as it's not set to disabled. - Fix pool number display. - Give BFGMiner -T message only if curses is in use. - Reinit_adl is no longer used. - API 'stats' allow devices to add their own stats also for testing/debug - API add getwork stats to BFGMiner - accesable from API 'stats' - Don't initialise variables to zero when in global scope since they're already initialised. - Get rid of unitialised variable warning when it's false. - Move a pool to POOL_REJECTING to be disabled only after 3 minutes of continuous rejected shares. - Some tweaks to reporting and logging. - API support new pool status - Add a temporarily disabled state for enabled pools called POOL_REJECTING and use the work from each longpoll to help determine when a rejecting pool has started working again.

BFGMiner Version 2.4.0 - May 3, 2012 - Only show longpoll warning once when it has failed. - Convert hashes to an unsigned long long as well. - Detect pools that have issues represented by endless rejected shares and disable them, with a parameter to optionally disable this feature. - Bugfix: Use a 64-bit type for hashes_done (miner_thread) since it can overflow 32-bit on some FPGAs - Implement an older header fix for a label existing before the pthread_cleanup macro. - Limit the number of curls we recruit on communication failures and with delaynet enabled to 5 by maintaining a per-pool curl count, and using a pthread conditional that wakes up when one is returned to the ring buffer. - Generalise add_pool() functions since they're repeated in add_pool_details. - Bugfix: Return failure, rather than quit, if BFwrite fails - Disable failing devices such that the user can attempt to re-enable them - Bugfix: thread_shutdown shouldn't try to free the device, since it's needed afterward - API bool's and 1TBS fixes - Icarus - minimise code delays and name timer variables - api.c V1.9 add 'restart' + redesign 'quit' so thread exits cleanly - api.c bug - remove extra ']'s in notify command - Increase pool watch interval to 30 seconds. - Reap curls that are unused for over a minute. This allows connections to be closed, thereby allowing the number of curl handles to always be the minimum necessary to not delay networking. - Use the ringbuffer of curls from the same pool for submit as well as getwork threads. Since the curl handles were already connected to the same pool and are immediately available, share submission will not be delayed by getworks. - Implement a scaleable networking framework designed to cope with any sized network requirements, yet minimise the number of connections being reopened. Do this by create a ring buffer linked list of curl handles to be used by getwork, recruiting extra handles when none is immediately available. - There is no need for the submit and getwork curls to be tied to the pool struct. - Do not recruit extra connection threads if there have been connection errors to the pool in question. - We should not retry submitting shares indefinitely or we may end up with a huge backlog during network outages, so discard stale shares if we failed to submit them and they've become stale in the interim. BFGMiner Version 2.3.6 - April 29, 2012 - Shorten stale share messages slightly. - Protect the freeing of current_hash under mutex_lock to prevent racing on it when set_curblock is hit concurrently. - Change default behaviour to submitting stale, removing the --submit-stale option and adding a --no-submit-stale option. - Make sure to start the getwork and submit threads when a pool is added on the fly. This fixes a crash when a pool is added to running BFGMiner and then switched to. - Faster hardware can easily outstrip the speed we can get work and submit shares when using only one connection per pool. - Test the queued list to see if any get/submits are already queued and if they are, start recruiting extra connections by generating new threads. - This allows us to reuse network connections at low loads but recuit new open connections as they're needed, so that BFGMiner can scale to hardware of any size. BFGMiner Version 2.3.5 - April 28, 2012 - Restarting BFGMiner leads to a socket that can't be bound for 60 seconds, so increase the interval that API binding waits to 30 seconds to minimise the number of times it will retry, spamming the logs. - Give a longpoll message for any longpoll that detects a block change, primary or backup, and also display which pool it was. - Decrease utility display to one decimal place. - Small cosmetic output alignment. - Add pool number to stale share message. - Add space to log output now that there is more screen real estate available. - Indentation clean up. - Remove thread id display from rejected shares as well. - Merge pull request #185 from Diapolo/diakgcn - add goffset support for diakgcn with -v 1 and update kernel version - Set have_longpoll to true when there is at least one pool with longpoll. - Don't display the thread ID since it adds no useful information over the device number. - Don't display the first 8 bytes of a share since they will always be zero at >= 1 difficulty. - work->longpoll is reset across test_work_current so we need to recheck what pool it belongs to. - Use longpolls from backup pools with failover-only enabled just to check for block changes, but don't use them as work. - Start longpoll only after we have tried to extract the longpoll URL. - Check for submitold flag on resubmit of shares, and give different message for stale shares on retry. - Check for submitold before submitstale. - Don't force fresh curl connections on anything but longpoll threads. - Create one longpoll thread per pool, using backup pools for those pools that don't have longpoll. - Use the work created from the longpoll return only if we don't have failover-enabled, and only flag the work as a longpoll if it is the current pool. - This will work around the problem of trying to restart the single longpoll thread on pool changes that was leading to race conditions. - It will also have less work restarts from the multiple longpolls received from different pools. - Remove the invalid entries from the example configuration file. - Add support for latest ATI SDK on windows. - Export missing function from libztex. - miner.php change socktimeoutsec = 10 (it only waits once) - Bugfix: Make initial_args a const char** to satisfy exec argument type warning (on Windows only) - miner.php add a timeout so you don't sit and wait ... forever - Create discrete persistent submit and get work threads per pool, thus allowing all submitworks belonging to the same pool to reuse the same curl handle, and all getworks to reuse their own handle. - Use separate handles for submission to not make getwork potentially delay share submission which is time critical. - This will allow much more reusing of persistent connections instead of opening new ones which can flood routers. - This mandated a rework of the extra longpoll support (for when pools are switched) and this is managed by restarting longpoll cleanly and waiting for a thread join. - miner.php only show the current date header once - miner.php also add current time like single rig page - miner.php display rig 'when' table at top of the multi-rig summary page - README - add some Ztex details - api.c include zTex in the FPGA support list - api.c ensure 'devs' shows PGA's when only PGA code is compiled - miner.c sharelog code consistency and compile warning fix - README correct API version number - README spelling error - api.c combine all pairs of sprintfs() - api.c uncomment and use BLANK (and COMMA) - Code style cleanup - Annotating frequency changes with the changed from value - README clarification of 'notify' command - README update for API RPC 'devdetails' - api.c 'devdetails' list static details of devices - Using less heap space as my TP-Link seems to not handle this much BFGMiner Version 2.3.4 - April 26, 2012 - New maintainership of code with modular FPGA/GPU focus, under BFGMiner name - Complete working support for cross-compiling Windows builds on Linux. - Fix usage of low --scan-time settings so it doesn't busy-loop - JSON API: Add new 'devdetail' command to get fixed device information - JSON API: Implement driver abstraction for extra device status - Icarus: Use epoll to wait for serial port input properly, when available - Icarus: Workaround buggy USB-UART that causes Icarus to stop mining rarely - Icarus: Estimate mining hashrate correctly, calibrated from real-world data - Icarus: Parallelize work setup with Icarus hash search improving performance - Icarus: More reliable detection and runtime - OpenCL: Move GPU-specific data fetching from JSON API to OpenCL driver - OpenCL: Dynamically load OpenCL library, to be more vendor-independent and allow use without actually having OpenCL (i.e. FPGA-only rigs). CGMiner Version 2.3.4 - April 25, 2012 - Extensively document the cause of GPU device issues and the use of --gpu-map. - Support for share logging - Detect poorly performing combination of SDK and phatk kernel and add verbose warning at startup. - Icarus update to new add_cgpu() - Icarus driver working with Linux and Windows - api.c fix unused variable compile warning - Display all OpenCL devices when -n is called as well to allow debugging of differential mapping of OpenCL to ADL. - Add a --gpu-map option which will allow arbitrarily mapping ADL devices to OpenCL devices for instances where association by enumeration alone fails. - Increase upper limit on number of extra items to queue as some FPGA code can't yet reliably keep many devices busy. - Display configuration file information when -c option is passed and only when file exists on loading default config file. - Display configuration file loaded, if any, and debug output if configuration file parsing failed. - Add missing ztex header to Makefile for distribution. - Document long-form COM port device names on Windows, required to specify serial ports above 9 - Include ztex bitstreams firmware in distribution and install if configured in. - Style police on driver-ztex.c - work_restart should only be changed by cgminer.c now - Shut down the api cleanly when the api thread is cancelled. This should allow the api socket to be closed successfully to next be reopened with app_restart. - Make a union for cgpu device handles, and rename "device" to "device_ztex" since it's Ztex-specific - Initialise name variable. - Remove unnecessary check for variable that always has memory allocated. - Bugfix: Missing "break" no-op in default case - Make the status window and log window as large as can fit on startup, rechecking to see if it can be enlarged after the fact. This allows any number of devices to be displayed provided the window is made long enough without corrupting the output. - Style police on libztex.c. - API add removepool like the screen interface - api.c escape required characters in return strings + pools returns the username - Set lp_path to NULL after free for consistency. - Removing dmalloc import left behind by mistake - Fixing leak in resp_hdr_cb - miner.php warning highlight GPU stats if they are zero (e.g. ADL not enabled) - miner.php highlight any device that isn't 'Enabled' - miner.php highlight any Status that isn't 'Alive' - miner.php optionally support multiple rigs - Initial Ztex support 1.15x board. CGMiner Version 2.3.3 - April 15, 2012 - Don't even display that cpumining is disabled on ./configure to discourage people from enabling it. - Do a complete cgminer restart if the ATI Display Library fails, as it does on windows after running for some time, when fanspeed reporting fails. - Cache the initial arguments passed to cgminer and implement an attempted restart option from the settings menu. - Disable per-device status lines when there are more than 8 devices since screen output will be corrupted, enumerating them to the log output instead at startup. - Reuse Vals[] array more than W[] till they're re-initialised on the second sha256 cycle in poclbm kernel. - Minor variable alignment in poclbm kernel. - Make sure to disable devices with any status not being DEV_ENABLED to ensure that thermal cutoff code works as it was setting the status to DEV_RECOVER. - Re-initialising ADL simply made the driver fail since it is corruption over time within the windows driver that's responsible. Revert "Attempt to re-initialise ADL should a device that previously reported fanspeed stops reporting it." - Microoptimise poclbm kernel by ordering Val variables according to usage frequency. CGMiner Version 2.3.2 - March 31, 2012 - Damping small changes in hashrate so dramatically has the tendency to always make the hashrate underread so go back to gentle damping instead. - Revert the crossover of variables from Vals to W in poclbm kernel now that Vals are the first declared variables so they're used more frequently. - Vals variables appearing first in the array in poclbm is faster. - Change the preferred vector width to 1 for Tahiti only, not all poclbm kernels. - Use a time constant 0.63 for when large changes in hashrate are detected to damp change in case the large change is an aliasing artefact instead of a real chang - Only increment stale counter if the detected stales are discarded. - Attempt to re-initialise ADL should a device that previously reported fanspeed stops reporting it. - Move the ADL setup and clearing to separate functions and provide a reinit_adl function to be used when adl fails while running. - Use slightly more damping on the decay time function in the never-ending quest to smooth off the hashmeter. - Set the starting fanspeed to a safe and fairly neutral 50% when autofan is enabled. - Provide locking around updates of cgpu hashrates as well to prevent multiple threads accessing data fields on the same device. - Display the beginning of the new block in verbose mode in the logs. - Reinstate old diablo kernel variable ordering from 120222, adding only goffset and vector size hint. The massive variable ordering change only helped one SDK on - Change the version number on the correct kernels. - api.c devicecode/osinfo incorrectly swapped for json - Add extensive instructions on how to make a native windows build. - Update version numbers of poclbm and diablo kernels as their APIs have also changed. - Use global offset parameter to diablo and poclbm kernel ONLY for 1 vector kernels. - Use poclbm preferentially on Tahiti now regardless of SDK. - Remove unused constant passed to poclbm. - Clean up use of macros in poclbm and use bitselect everywhere possible. - Add vector type hint to diablo kernel. - Add worksize and vector attribute hints to the poclbm kernel. - Spaces for non-aligned variables in poclbm. - Swap Vals and W variables where they can overlap in poclbm. - More tidying of poclbm. - Tidy up first half of poclbm. - Clean up use of any() by diablo and poclbm kernels. - Minor variable symmetry changes in poclbm. - Put additions on separate lines for consistency in poclbm. - Consolidate last use of W11 into Vals4 in poclbm. - Change email due to SPAM - api.c miner.php add a '*' to the front of all notify counters -

of course - API returns the simple device history with the 'notify' command - code changes for supporting a simple device history - api.c Report an OS string in config to help with device issues - api.c fix Log Interval - integer in JSON - api.c config 'Device Code' to show list of compiled devices + README - api.c increase buffer size close to current code allowable limit - removed 8-component vector support from kernel, as this is not supported in CGMINER anyway - forgot to update kernel modification date, fixed ;) - reordered an addition in the kernel, which results in less instructions used in the GPU ISA code for GCN - miner.php: option for readonly or check privileged access - Ignore reduntant-with-build options --disable-gpu, --no-adl, and --no-restart - miner.php: ereg_replace is DEPRECATED so use preg_replace instead - Make curses TUI support optional at compile-time. - Bugfix: AC_ARG_WITH provides withval instead of enableval - miner.php split devs output for different devices - api.c: correct error messages - icarus.c modify (regular) timeout warning to only be debug -

Add API support for Icarus and Bitforce - Next API version is 1.4 (1.3 is current) - README/api.c add "When" the request was processed to STATUS - Bugfix: ZLX to read BitFORCE temp, not ZKX -.- - Use libudev to autodetect BitFORCE GPUs, if available - Use the return value of fan_autotune to set fan_optimal instead of passing it as a pointer. - Pass the lasttemp from the device we're using to adjust fanspeed in twin devices. - fix the name to 3 chars, fix the multi-icarus support - Bugfix: "-S auto" is the default if no -S is specified, and there is no such delay in using it - README add information missing from --scan-serial - Update README RPC API Version comment - Bugfix: Allow enabling CPU even without OpenCL support - Change failed-to-mine number of requested shares messge to avoid segfault on recursive calling of quit(). - Get rid of extra char which is just truncated in poclbm kernel. - only small code formating changes - removed vec_step() as this could lead to errors on older SDKs - unified code for generating nonce in kernel and moved addition of base to the end -> faster CGMiner Version 2.3.1 - February 24, 2012 - Revert input and output code on diakgcn and phatk kernels to old style which worked better for older hardware and SDKs. - Add a vector*worksize parameter passed to those kernels to avoid one op. - Increase the speed of hashrate adaptation. - Only send out extra longpoll requests if we want longpolls. - API implement addpool command - API return the untouched Total MH also (API now version 1.3) - Add enable/disablepool to miner.php example and reduce font size 1pt CGMiner Version 2.3.0 - February 23, 2012 - Consider extra longpoll work items as staged_extra so as to make sure we queue more work if queueing regular work items as longpolls. - Use diablo kernel on all future SDKs for Tahiti and set preferred vector width to 1 on poclbm kernel only. - Explicitly type the constants in diakgcn kernel as uint, to be in line with poclbm kernel. - Reset all hash counters at the same time as resetting start times to get accurate hashrates on exiting which is mandatory for benchmarking. - Report thread out before it starts to avoid being flagged as sick when waiting for the first work item. - Don't disable and re-enable devices as they may recover and in the meantime have their status set to OFF. - API new commands enablepool and disablepool (version already incremented) - Tolerate new-format temperature readings for bitforce - Modify cgminer.c pool control to allow API to call it - Bugfix: Fix BitFORCE driver memory leak in debug logging - Extra byte was being unused in poclbm leading to failure on some platforms. - Explicitly type the constants in poclbm kernel as uint. - Don't save 'include' when saving the configuration - Allow configuration file to include another recursively - Use the SDK and hardware information to choose good performing default kernels. - Move phatk kernel to offset vector based nonce bases as well. - Add a --benchmark feature which works on a fake item indefinitely to compare device performance without any server or networking influence. - Allow writing of multiple worksizes to the configuration file. - Allow writing of multiple vector sizes to the configuration file. - Allow writing of multiple kernels to the configuration file. - Allow multiple different kernels to be chosen per device. - Allow the worksize to be set per-device. - Allow different vectors to be set per device. - If we're well below the target temperature, increase gpu engine speed back to maximum in case we have gotten lost between profiles during an idle period. - We should be setting the value of fan_optimal, not its address. - As all kernels will be new versions it's an opportunity to change the .bin format and make it simpler. Specifying bitalign is redundant and long can be l. - Use any() in kernel output code. - Put the nonce for each vector offset in advance, avoiding one extra addition in the kernel. - Reset times after all mining threads are started to make estimating hashrates easier at startup. - Bugfix: allow no-exec (NX) stack - Fix minor warning. - fix the bitforce.c code style follow 1TBS - fix icarus.c compile warning - small changes to speedup no vec for AMD 898.1 OCL runtime - Update licensing to GPL V3. - Reset the longpoll flag after it's been used once to prevent it restarting work again. - Begin import of DiabloMiner kernel. - Modify API debug messages to say API instead of DBG - When API shuts down cgminer don't kill itself - Don't make rolled work from the longpoll be seen as other longpoll work items. - API add 'privileged' command so can verify access level - Set the lp_sent variable under lock since there will almost always be a race on setting this variable, potentially leading to multiple LPs being sent out. - API restrict access to all non display commands by default - Update API version to 1.2 for new 'Log Interval' - API add --log Interval to 'config' reply - --api-allow special case 0/0 means all CGMiner Version 2.2.7 - February 20, 2012 - Send out extra longpolls when we have switched pools and the longpoll thread is still bound to the old one. This is particularly useful with p2pool where longpolls do not correlate with main bitcoin block change and would have led to high reject rates on failover. - Store whether a work item is the result of a longpoll or not in struct work and use it to help determine block changes directly from the work longpoll bool. - Keep track of when a longpoll has been sent for a pool and if the current pool is requesting work but has not sent a longpoll request, convert one of the work items to a longpoll. - Store the longpoll url in the pool struct and update it from the pool_active test in case it changes. This is to allow further changes to longpoll management on switching pools. - Re-check for a longpoll supporting pool every 30 seconds if none is found initially. - Report threads as busy waiting on getwork on startup to avoid them being flagged sick on startup during slow networking. - Allow devices that are disabled due to overheating to be flagged as recovering instead of disabling them and re-enable them if they're below ideal temperatures - Tahiti prefers worksize 64 with poclbm. - No need to expressly retain the opencl program now that the zero binary issue is fixed. This actually fixes cgminer to work with the latest SDK included with the ATI catalyst driver 12.2. - Show error code on any opencl failure status. - Add detection for version 898.1 SDK as well but only give SDK 2.6 warning once on startup instead of with each device initialisation. - Always use a fresh connection for longpoll as prolonged persistent connections can fail for many reasons. - Keep track of intended engine clock speed and only adjust up if it's higher than the last intended speed. This avoids setting the clock speed to one relative to a lower profile one by mistake. - Use gpu-memdiff on startup if an engine clockspeed is set and a memdiff value is set. - Revert "Adjust engine speed up according to performance level engine setting, not the current engine speed." - ineffectual. - Freeze the queues on all threads that are sent the pause message to prevent them trying to start up again with saved pings in their queues. - Updates to diakgcn kernel/ - Consolidate all screen updates to the watchdog thread and touch both windows before refresh. - Curses will be disabled in clean_up so don't do it early in kill_work, and disable_adl so that GPU settings may be restored to normal in case shutting down curses leads to instability on windows. - Stop the mining threads before trying to kill them. - Plain refresh() does not give reliably screen updates so get rid of all uses of it. - First release with working diakgcn kernel. CGMiner Version 2.2.6 - February 16, 2012 - Provide warning on each startup about sdk 2.6 - Fix unused warnings on win32. - bitforce: Simplify BFopen WIN32 ifdef/else - Fix initialization warning with jansson 1.3 - bitforce: Cleanup extraneous TODO that isn't needed - Move tcsetattr (and new tcflush) into *nix BFopen to simplify things a bit - Add message explaining 2nd thread disabling for dynamic mode and how to tune it. - Move logwindow down once number of devices is known. - Automatically choose phatk kernel for bitalign non-gcn ATI cards, and then only select poclbm if SDK2.6 is detected. - Allow the refresh interval to be adjusted in dynamic intensity with a --gpu-dyninterval parameter. - Make curses display visible right from the beginning and fix the window sizes so the initial messages don't get lost once the status window is drawn. - The amount of work scanned can fluctuate when intensity changes and since we do this one cycle behind, we increment the work more than enough to prevent repeati - bitforce: Set a 30 second timeout for serial port on Windows, since the default is undefined - Use PreVal4addT1 instead of PreVal4 in poclbm kernel. - Import PreVal4 and PreVal0 into poclbm kernel. - Import more prepared constants into poclbm kernel. - Keep variables in one array but use Vals[] name for consistency with other kernel designs. - Replace constants that are mandatorily added in poclbm kernel with one value. - Remove addition of final constant before testing for result in poclbm kernel. - Hand optimise variable addition order. - Hand optimise first variable declaration order in poclbm kernel. - Radical reordering machine based first pass to change variables as late as possible, bringing their usage close together. - fix strcpy NULL pointer if env HOME unset. - bitforce: Disable automatic scanning when at least one device is specified manually - Unroll all poclbm additions to enable further optimisations. CGMiner Version 2.2.5 - February 13, 2012 - Make output buffer write only as per Diapolo's suggestion. - Constify nonce in poclbm. - Use local and group id on poclbm kernel as well. - Microoptimise phatk kernel on return code. - Adjust engine speed up according to performance level engine setting, not the current engine speed. - Try to load a binary if we've defaulted to the poclbm kernel on SDK2.6 - Use the poclbm kernel on SDK2.6 with bitalign devices only if there is no binary available. - Further generic microoptimisations to poclbm kernel. - The longstanding generation of a zero sized binary appears to be due to the OpenCL library putting the binary in a RANDOM SLOT amongst 4 possible binary locations. Iterate over each of them after building from source till the real binary is found and use that. - Fix harmless warnings with -Wsign-compare to allow cgminer to build with -W. - Fix missing field initialisers warnings. - Put win32 equivalents of nanosleep and sleep into compat.h fixing sleep() for adl.c. - Restore compatibility with Jansson 1.3 and 2.0 (api.c required 2.1) - Modularized logging, support for priority based logging - Move CPU chipset specific optimization into device-cpu CGMiner Version 2.2.4 - February 11, 2012 - Fix double definition of A0 B0 to zeroA zeroB. - Retain cl program after successfully loading a binary image. May decrease failures to build kernels at startup. - Variable unused after this so remove setting it. - BFI INT patching is not necessarily true on binary loading of files and not true on ATI SDK2.6+. Report bitalign instead. - Various string fixes for reject reason. - Generalize --temp-cutoff and implement support for reading temperature from BitFORCE FPGAs - Change message from recovered to alive since it is used on startup as well as when a pool has recovered. - Start mining as soon as any pool is found active and rely on the watchpool thread to bring up other pools. - Delayed responses from testing pools that are down can hold up the watchdog thread from getting to its device testing code, leading to false detection of the GPU not checking in, and can substantially delay auto gpu/auto fan management leading to overheating. Move pool watching to its own thread. - Bugfix: BitFORCE index needs to be static to count correctly - Space out retrieval of extra work according to the number of mining threads. - Make shutdown more robust. Enable the input thread only after the other threads exist. Don't kill off the workio thread and use it to exit main() only if there is an unexpected problem. Use kill_work() for all anticipated shutdowns where possible. Remove unused thread entry. - Change poclbm version number. - One array is faster than 2 separate arrays so change to that in poclbm kernel. - Microoptimisations to poclbm kernel which increase throughput slightly. - Import diablominer kernel. Currently disabled as not working. - Import diapolo kernel. Currently disabled as not working. - Conflicting entries of cl_kernel may have been causing problems, and automatically chosen kernel type was not being passed on. Rename the enum to cl_kernels and store the chosen kernel in each clState. - Set cl_amd_media_ops with the BITALIGN flag and allow non-bitselect devices to build. - ALlow much longer filenames for kernels to load properly. - Allow different kernels to be used by different devices and fix the logic fail of overcorrecting on last commit with !strstr. - Fix kernel selection process and build error. - queue_phatk_kernel now uses CL_SET_VARG() for base-nonce(s), too - added OpenCL >= 1.1 detection code, in preparation of OpenCL 1.1 global offset parameter support - Use K array explicitly to make it clear what is being added. - Work items have a tendency to expire at exactly the same time and we don't queue extra items when there are plenty in the queue, regardless of age. Allow extra work items to be queued if adequate time has passed since we last requested work even if over the limit. - Discard work when failover-only is enabled and the work has come from a different pool. - Missing include to build on newer mingw32. - Move from the thread safe localtime_r to regular localtime which is the only one supported on newer pthread libraries on mingw32 to make it compile with the newer ming. Thread safety is of no importance where localtime is used in this code. - Define in_addr_t in windows if required - sys/wait.h not required in windows - Allow API to restrict access by IP address - Add pool switching to example miner.php - Display X-Reject-Reason, when provided - Remove the test for whether the device is on the highest profil level before raising the GPU speed as it is ineffectual and may prevent raising the GPU speed. - Remove unnecessary check for opt_debug one every invocation of applog at LOG_DEBUG level and place the check in applog(). CGMiner Version 2.2.3 - February 6, 2012 - Revert "Rewrite the convoluted get_work() function to be much simpler and roll work as much as possible with each new work item." This seems to cause a race on work in free_work(). Presumably other threads are still accessing the structure. CGMiner Version 2.2.2 - February 6, 2012 - Provide support for the submitold extension on a per-pool basis based on the value being detected in a longpoll. - Don't send a ping to a dynamic device if it's not enabled as that will just enable it for one pass and then disable it again. - Rewrite the convoluted get_work() function to be much simpler and roll work as much as possible with each new work item. - Roll as much work as possible from the work returned from a longpoll. - Rolling work on each loop through the mining thread serves no purpose. - Allow to stage more than necessary work items if we're just rolling work. - Replace divide_work with reuse_work function used twice. - Give rolled work a new ID to make sure there is no confusion in the hashtable lookups. - Remove now-defunct hash_div variables. - Remove unused get_dondata function. - Silence ADL warnings. - Silence unused parameter warnings. - Stagger the restart of every next thread per device to keep devices busy ahead of accessory threads per device. - Deprecate the --donation feature. Needlessly complex, questionable usefulness, depends on author's server and a central pool of some kind, and was not heavily adopted. - It's devices that report back now, not threads, update message. - Continue auto-management of fan and engine speeds even if a device is disabled for safety reasons. - No need to check we're highest performance level when throttling GPU engine speed. - Abstract out tests for whether work has come from a block that has been seen before and whether a string is from a previously seen block. - Probe but don't set the timeout to 15 seconds as some networks take a long time to timeout. - Remove most compiler warnings from api.c - Add last share's pool info in cgpu_info - Allow the OpenCL platform ID to be chosen with --gpu-platform. - Iterate over all platforms displaying their information and number of devices when --ndevs is called. - Deprecate main.c - Some networks can take a long time to resolve so go back to 60 second timeouts instead of 15. - Only enable curses on failure if curses is desired. - Fix warnings in bitforce.c - Bugfix: Need to open BitForce tty for read-write - Fix various build issues. - Modularize code: main.c -> device-cpu + device-gpu - Fix phatk kernel not working on non-bitalign capable devices (Nvidia, older ATI). - Update poclbm kernel for better performance on GCN and new SDKs with bitalign support when not BFI INT patching.

Instead give a warning about - Display error codes should ADL not return ADL_OK in the more critical function calls. - Fix unused warning. - Fix compile warnings in api.c - Add extensive ADL based device info in debug mode. - Make --ndevs display verbose opencl information as well to make debugging version information easier. - Display information about the opencl platform with verbose enabled. - Explicitly check for nvidia in opencl platform strings as well. CGMiner Version 2.2.0 - January 29, 2012 NOTE: GPU Device order will change with this release with ATI GPUs as cgminer now can enumerate them according to their Bus ID which means the values should now correlate with their physical position on the motherboard. - Default to poclbm kernel on Tahiti (7970) since phatk does not work, even though performance is sub-standard so that at least it will mine successfully by defau - Retain cl program after every possible place we might build the program. - Update ADL SDK URL. - Fix potential overflow. - Map GPU devices to virtual devices in their true physical order based on BusNumber. - Change the warning that comes with failure to init cl on a device to be more generic and accurate. - Advertise longpoll support in X-Mining-Extensions - Detect dual GPU cards by iterating through all GPUs, finding ones without fanspeed and matching twins with fanspeed one bus ID apart. - Do not attempt to build the program that becomes the kernel twice. This could have been leading to failures on initialising cl. - Some opencl compilers have issues with no spaces after -D in the compiler options. - Allow intensity up to 14. - Use calloced stack memory for CompilerOptions to ensure sprintf writes to the beginning of the char. - Whitelist 79x0 cards to prefer no vectors as they perform better without. - Adjust fan speed gently while in the optimal range when temperature is drifting to minimise overshoot in either direction. - Detect dual GPU cards via the indirect information of - 1st card has a fan controller. 2nd card does not have a fan controller, cards share the same device name - Instead of using the BFI_INT patching hack on any device reporting cl_amd_media_ops, create a whitelist of devices that need it. This should enable GCN architec - Fixed API compiling issue on OS X - Add more explanation of JSON format and the 'save' command - Return an error if using ADL API commands when it's not available - Read off lpThermalControllerInfo from each ADL device. - Add ADL_Overdrive5_ThermalDevices_Enum interface. - Add API commands: config, switchpool, gpu settings, save - Implement socks4 proxy support. - Fix send() for JSON strings - Introduce a --net-delay option which guarantees at least 250ms between any networking requests to not overload slow routers. - Generalise locking init code. - Allow invalid values to be in the configuration file, just skipping over them provided the rest of the file is valid JSON. This will allow older configurat - Allow CPU mining explicitly enable only if other mining support is built in. - BitForce FPGA support - Configure out building and support of all CPU mining code unless --enable-cpumining is enabled. - Allow parsed values to be zero which will allow 0 values in the config file to work. - Advertise that we can make our own midstate, so the pool can skip generating it for us - Refactor the CPU scanhash_* functions to use a common API. Fixes bugs. - Don't consider a pool lagging if a request has only just been filed. This should decrease the false positives for "pool not providing work fast enough". - Invalidating work after longpoll made hash_pop return no work giving a false positive for dead pool. Rework hash_pop to retry while finds no staged work u - Remove TCP_NODELAY from curl options as many small packets may be contributing to network overload, when --net-delay is enabled. - Refactor miner_thread to be common code for any kind of device - Simplify submit_nonce loop and avoid potentially missing FOUND - 1 entry.

This fixes the very rare possibility that a block solve on solo mining was missed. - Add x86_64 w64 mingw32 target - Allow a fixed speed difference between memory and GPU clock speed with --gpu-memdiff that will change memory speed when GPU speed is changed in autotune mode. - Don't load the default config if a config file is specified on the command line. - Don't build VIA on apple since -a auto bombs instead of gracefully ignoring VIA failing. - Build fix for dlopen/dlclose errors in glibc. CGMiner Version 2.0.7 - October 17, 2011 - Support work without midstate or hash1, which are deprecated in bitcoind 0.5+ - Go to kernel build should we fail to clCreateProgramWithBinary instead of failing on that device. This should fix the windows problems with devices not initialising. - Support new configuration file format courtesy of Chris Savery which can write the config file from the menu and will load it on startup. - Write unix configuration to .cgminer/cgminer.conf by default and prompt to overwrite if given a filename from the menu that exists. CGMiner Version 2.0.6 - October 9, 2011 - Must initialise the donorpool mutex or it fails on windows. - Don't make donation work interfere with block change detection allowing donation to work regardless of the block chain we're mining on. - Expire shares as stale with a separate timeout from the scantime, defaulting to 120 seconds. - Retry pools after a delay of 15 seconds if none can be contacted on startup unless a key is pressed. - Don't try to build adl features without having adl. - Properly check shares against target difficulty - This will no longer show shares when solo mining at all unless they're considered to be a block solve. - Add altivec 4 way (cpu mining) support courtesy of Gilles Risch. - Try to use SSL if the server supports it. - Display the total solved blocks on exit (LOL if you're lucky). - Use ADL activity report to tell us if a sick GPU is still busy suggesting it is hard hung and do not attempt to restart it. CGMiner Version 2.0.5 - September 27, 2011 - Intensity can now be set to dynamic or static values per-device. - New donation feature --donation sends a proportion of shares to author's account of choice, but is disabled by default! - The hash being displayed and block detection has been fixed. - Devices not being mined on will not attempt to be ADL managed. - Intensity is now displayed per GPU device. - Make longpoll attempt to restart as often as opt_retries specifies. - We weren't rolling work as often as we could. - Correct some memory management issues. - Build fixes. - Don't mess with GPUs if we don't have them. CGMiner Version 2.0.4 - September 23, 2011 - Confused Longpoll messages should be finally fixed with cgminer knowing for sure who found the new block and possibly avoiding a rare crash. - Display now shows the actual hash and will say BLOCK! if a block is deemed solved. - Extra spaces, which would double space lines on small terminals, have been removed. - Fan speed change is now damped if it is already heading in the correct direction to minimise overshoot. - Building without opencl libraries is fixed. - GPUs are autoselected if there is only one when in the GPU management menu. - GPU menu is refreshed instead of returning to status after a GPU change. CGMiner Version 2.0.3 - September 17, 2011 - Various modes of failure to set fanspeeds and adl values have been addressed and auto-fan should work now on most hardware, and possibly other values which previously would not have worked. - Fixed a crash that can occur on switching pools due to longpoll thread races. - Use ATISTREAMSDKROOT if available at build time. - Fanspeed management is returned to the driver default on exit instead of whatever it was when cgminer was started. - Logging of events deemed WARNING or ERR now will display even during periods where menu input is being awaited on. CGMiner Version 2.0.2 - September 11, 2011 - Exit cleanly if we abort before various threads are set up or if they no longer exist. - Fix a rare crash in HASH_DEL due to using different mutexes to protect the data. - Flag devices that have never started and don't allow enabling of devices without restarting them. - Only force the adapter speed to high if we've flagged this device as being managed. - Flag any devices with autofan or autogpu as being managed. - Use a re-entrant value to store what fanspeed we're trying to set in case the card doesn't support small changes. Force it to a multiple of 10% if it fails on trying to speed up the fan. - Do not bother resetting values to old ones if changes to GPU parameters report failure, instead returning a failure code only if the return value from get() differs. - Remove redundant check. - Only display supported values from fanspeed on change settings. - Missing bracket from output. - Display fan percentage on devices that only support reporting percent and not RPM. - Properly substitute DLOPEN flags to build with ADL support when -ldl is needed and not when opencl is not found. CGMiner Version 2.0.1 - September 9, 2011 - Fix building on 32bit glibc with dlopen with -lpthread and -ldl - ByteReverse is not used and the bswap opcode breaks big endian builds. Remove it. - Ignore whether the display is active or not since only display enabled devices work this way, and we skip over repeat entries anwyay. - Only reset values on exiting if we've ever modified them. - Flag adl as active if any card is successfully activated. - Add a thermal cutoff option as well and set it to 95 degrees by default. - Change the fan speed by only 5% if it's over the target temperature but less than the hysteresis value to minimise overshoot down in temperature. - Add a --no-adl option to disable ADL monitoring and GPU settings. - Only show longpoll received delayed message at verbose level. - Allow temperatures greater than 100 degrees. - We should be passing a float for the remainder of the vddc values. - Implement accepting a range of engine speeds as well to allow a lower limit to be specified on the command line. - Allow per-device fan ranges to be set and use them in auto-fan mode. - Display which GPU has overheated in warning message. - Allow temperature targets to be set on a per-card basis on the command line. - Display fan range in autofan status. - Setting the hysteresis is unlikely to be useful on the fly and doesn't belong in the per-gpu submenu. - With many cards, the GPU summaries can be quite long so use a terse output line when showing them all. - Use a terser device status line to show fan RPM as well when available. - Define max gpudevices in one macro. - Allow adapterid 0 cards to enumerate as a device as they will be non-AMD cards, and enable ADL on any AMD card. - Do away with the increasingly confusing and irrelevant total queued and efficiency measures per device. - Only display values in the log if they're supported and standardise device log line printing. CGMiner Version 2.0.0 - September 6, 2011 Major feature upgrade - GPU monitoring, (over)clocking and fan control for ATI GPUs. New command line switches: --auto-fan- Automatically adjust all GPU fan speeds to maintain a target temperature --auto-gpu- Automatically adjust all GPU engine clock speeds to maintain a target temperature --gpu-engine Set the GPU engine (over)clock in Mhz - one value for all or separate by commas for per card. --gpu-fan Set the GPU fan percentage - one value for all or separate by commas for per card. --gpu-memclock Set the GPU memory (over)clock in Mhz - one value for all or separate by commas for per card. --gpu-powertune Set the GPU powertune percentage - one value for all or separate by commas for per card. --gpu-vddc Set the GPU voltage in Volts - one value for all or separate by commas for per card. --temp-hysteresis Set how much the temperature can fluctuate outside limits when automanaging speeds (default: 3) --temp-overheat Set the overheat temperature when automatically managing fan and GPU speeds (default: 85) --temp-target Set the target temperature when automatically managing fan and GPU speeds (default: 75) - Implement ATI ADL support for GPU parameter monitoring now and setting later (temp, fan, clocks etc.). - Check for the presence of the ADL header files in ADL_SDK. - Import adl_functions.h from amd overdrive ctrl. - Implement a setup function that tries to detect GPUs that support the ADL and link in the parameters into the gpus struct. - Put a summary of monitoring information from the GPU menu. - Implement changing memory speed and voltage on the fly. - Implement fan speed setting. - Minor corrections to set fan speed by percentage. - Make sure to read off the value in RPM only. - Implement auto fanspeed adjustment to maintain a target temperature and fanspeed below 85%, with an overheat check that will speed the fan up to 100%. - Add an --auto-fan command line option to allow all GPUs to have autofan enabled from startup. - Add a gpu autotune option which adjusts GPU speed to maintain a target temperature within the bounds of the default GPU speed and any overclocking set. - Avoid a dereference if the longpoll thread doesn't exist. - Clean up by setting performance profiles and fan settings to startup levels on exit. - Add a small amount of hysteresis before lowering clock speed. - Allow target, overheat and hysteresis temperatures to be set from command line. - Combine all stats collating into one function to avoid repeating function calls on each variable. - Add gpu statistics to debugging output via the watchdog thread. - Implement menus to change temperature limits. - Implement setting the GPU engine clock speed of all devices or each device as a comma separated value. - Implement setting the GPU memory clock speed of all devices or each device as a comma separated value. - Implement setting the GPU voltage of all devices or each device as a comma separated value. - Implement setting the GPU fan speed of all devices or each device as a comma separated value. - Add support for monitoring powertune setting. - Implement changing of powertune value from the GPU change settings menu. - Get the value of powertune in get_stats. - Implement setting the GPU powertune value of all devices or each device as a comma separated value. - Remove the safety checks in speed setting since confirmation is done first in the menu, then show the new current values after a short pause. - Force the speed to high on startup and restore it to whatever the setting was on exit. - Add temperature to standard output where possible and use more compact output. - Move and print at the same time in curses to avoid random trampling display errors. - Update the status window only from the watchdog thread, do not rewrite the top status messages and only refresh once all the status window is complete, clearing the window each time to avoid corruption. - Set a safe starting fan speed if we're automanaging the speeds. - Provide locking around all adl calls to prevent races. - Lower profile settings cannot be higher than higher profile ones so link any drops in settings. - Add new needed text files to distribution. - Queue requests ignoring the number of staged clones since they get discarded very easily leading to false positives for pool not providing work fast enough. - Include libgen.h in opt.c to fix win32 compilation warnings. - Fix compilation warning on win32. - Add the directory name from the arguments cgminer was called from as well to allow it running from a relative pathname. - Add a --disable-adl option to configure and only enable it if opencl support exists. - Retry before returning a failure to get upstream work as a failure to avoid false positives for pool dead. - Retry also if the decoding of work fails. - Use the presence of X-Roll-Ntime in the header as a bool for exists unless N is found in the response. CGMiner Version 1.6.2 - September 2, 2011 - Add --failover-only option to not leak work to backup pools when the primary pool is lagging. - Change recommendation to intensity 9 for dedicated miners. - Fix the bouncing short term value by allowing it to change dynamically when the latest value is very different from the rolling value, but damp the change when it gets close. - Use the curses_lock to protect the curses_active variable and test it under lock. - Go back to requesting work 2/3 of the way through the current scantime with CPU mining as reports of mining threads running out of work have occurred with only 5 seconds to retrieve work. - Add start and stop time scheduling for regular time of day running or once off start/stop options. - Print summary on quit modes. - Put some sanity checks on the times that can be input. - Give a verbose message when no active pools are found and pause before exiting. - Add verbose message when a GPU fails to initialise, and disable the correct GPU. - Cryptopp asm32 was not correctly updated to the incremental nonce code so the hash counter was bogus. - Get rid of poorly executed curl check. - If curl does not have sockopts, do not try to compile the json_rpc_call_sockopt_cb function, making it possible to build against older curl libraries. - Most people expect /usr/local when an unspecified prefix is used so change to that. - Rename localgen occasions to getwork fail occasions since localgen is unrelated now. CGMiner Version 1.6.1 - August 29, 2011 - Copy cgminer path, not cat it. - Switching between redrawing windows does not fix the crash with old libncurses, so redraw both windows, but only when the window size hasn't changed. - Reinstate minimum 1 extra in queue to make it extremely unlikely to ever have 0 staged work items and any idle time. - Return -1 if no input is detected from the menu to prevent it being interpreted as a 0. - Make pthread, libcurl and libcurses library checks mandatory or fail. - Add a --disable-opencl configure option to make it possible to override detection of opencl and build without GPU mining support. - Confusion over the variable name for number of devices was passing a bogus value which likely was causing the zero sized binary issue. - cgminer no longer supports default url user and pass so remove them. - Don't show value of intensity since it's dynamic by default. - Add options to explicitly enable CPU mining or disable GPU mining. - Convert the opt queue into a minimum number of work items to have queued instead of an extra number to decrease risk of getting idle devices without increasing risk of higher rejects. - Statify tv_sort. - Check for SSE2 before trying to build 32 bit SSE2 assembly version. Prevents build failure when yasm is installed but -msse2 is not specified. - Add some defines to configure.ac to enable exporting of values and packaging, and clean up output. - Give convenient summary at end of ./configure. - Display version information and add --version command line option, and make sure we flush stdout. - Enable curses after the mining threads are set up so that failure messages won't be lost in the curses interface. - Disable curses after inputting a pool if we requested no curses interface. - Add an option to break out after successfully mining a number of accepted shares. - Exit with a failed return code if we did not reach opt_shares. - The cpu mining work data can get modified before we copy it if we submit it async, and the sync submission is not truly sync anyway, so just submit it sync. CGMiner Version 1.6.0 - August 26, 2011 - Make restarting of GPUs optional for systems that hang on any attempt to restart them. Fix DEAD status by comparing it to last live time rather than last attempted restart time since that happens every minute. - Move staged threads to hashes so we can sort them by time. - Create a hash list of all the blocks created and search them to detect when a new block has definitely appeared, using that information to detect stale work and discard it. - Update configure.ac for newer autoconf tools. - Use the new hashes directly for counts instead of the fragile counters currently in use. - Update to latest sse2 code from cpuminer-ng. - Allow LP to reset block detect and block detect lp flags to know who really came first. - Get start times just before mining begins to not have very slow rise in average. - Add message about needing one server. - We can queue all the necessary work without hitting frequent stales now with the time and string stale protection active all the time. This prevents a pool being falsely labelled as not providing work fast enough. - Include uthash.h in distro. - Implement SSE2 32 bit assembly algorithm as well. - Fail gracefully if unable to open the opencl files. - Make cgminer look in the install directory for the .cl files making make install work correctly. - Allow a custom kernel path to be entered on the command line. - Bump threshhold for lag up to maximum queued but no staged work. - Remove fragile source patching for bitalign, vectors et. al and simply pass it with the compiler options. - Actually check the value returned for the x-roll-ntime extension to make sure it isn't saying N. - Prevent segfault on exit for when accessory threads don't exist. - Disable curl debugging with opt protocol since it spews to stderr. CGMiner Version 1.5.8 - August 23, 2011 - Minimise how much more work can be given in cpu mining threads each interval. - Make the fail-pause progressively longer each time it fails until the network recovers. - Only display the lagging message if we've requested the work earlier. - Clean up the pool switching to not be dependent on whether the work can roll or not by setting a lagging flag and then the idle flag. - Only use one thread to determine if a GPU is sick or well, and make sure to reset the sick restart attempt time. - The worksize was unintentionally changed back to 4k by mistake, this caused a slowdown. CGMiner Version 1.5.7 - August 22, 2011 - Fix a crash with --algo auto - Test at appropriate target difficulty now. - Add per-device statics log output with --per-device-stats - Fix breakage that occurs when 1 or 4 vectors are chosen on new phatk. - Make rolltime report debug level only now since we check it every work item. - Add the ability to enable/disable per-device stats on the fly and match logging on/off. - Explicitly tell the compiler to retain the program to minimise the chance of the zero sized binary errors. - Add one more instruction to avoid one branch point in the common path in the cl return code. Although this adds more ALUs overall and more branch points, the common path code has the same number of ALUs and one less jmp, jmps being more expensive. - Explicitly link in ws2_32 on the windows build and update README file on how to compile successfully on windows. - Release cl resources should the gpu mining thread abort. - Attempt to restart a GPU once every minute while it's sick. - Don't kill off the reinit thread if it fails to init a GPU but returns safely. - Only declare a GPU dead if there's been no sign of activity from the reinit thread for 10 mins. - Never automatically disable any pools but just specify them as idle if they're unresponsive at startup. - Use any longpoll available, and don't disable it if switching to a server that doesn't have it. This allows you to mine solo, yet use the longpoll from a pool even if the pool is the backup server. - Display which longpoll failed and don't free the ram for lp_url since it belongs to the pool hdr path. - Make the tcp setsockopts unique to linux in the hope it allows freebsd et. al to compile. CGMiner Version 1.5.6 - August 17, 2011 - New phatk and poclbm kernels. Updated phatk to be in sync with latest 2.2 courtesy of phateus. Custom modified to work best with cgminer. - Updated output buffer code to use a smaller buffer with the kernels. - Clean up the longpoll management to ensure the right paths go to the right pool and display whether we're connected to LP or not in the status line. CGMiner Version 1.5.5 - August 16, 2011 - Rework entirely the GPU restart code. Strike a balance between code that re-initialises the GPU entirely so that soft hangs in the code are properly managed, but if a GPU is completely hung, the thread restart code fails gracefully, so that it does not take out any other code or devices. This will allow cgminer to keep restarting GPUs that can be restarted, but continue mining even if one or more GPUs hangs which would normally require a reboot. - Add --submit-stale option which submits all shares, regardless of whether they would normally be considered stale. - Keep options in alphabetical order. - Probe for slightly longer for when network conditions are lagging. - Only display the CPU algo when we're CPU mining. - As we have keepalives now, blaming network flakiness on timeouts appears to have been wrong. Set a timeout for longpoll to 1 hour, and most other network connectivity to 1 minute. - Simplify output code and remove HW errors from CPU stats. - Simplify code and tidy output. - Only show cpu algo in summary if cpu mining. - Log summary at the end as per any other output. - Flush output. - Add a linux-usb-cgminer guide courtesy of Kano. CGMiner Version 1.5.4 - August 14, 2011 - Add new option: --monitor Option lets user specify a command that will get forked by cgminer on startup. cgminer's stderr output subsequently gets piped directly to this command. - Allocate work from one function to be able to initialise variables added later. - Add missing fflush(stdout) for --ndevs and conclusion summary. - Preinitialise the devices only once on startup. - Move the non cl_ variables into the cgpu info struct to allow creating a new cl state on reinit, preserving known GPU variables. - Create a new context from scratch in initCQ in case something was corrupted to maximise our chance of succesfully creating a new worker thread. Hopefully this makes thread restart on GPU failure more reliable, without hanging everything in the case of a completely wedged GPU. - Display last initialised time in gpu management info, to know if a GPU has been re-initialised. - When pinging a sick cpu, flush finish and then ping it in a separate thread in the hope it recovers without needing a restart, but without blocking code elsewhere. - Only consider a pool lagging if we actually need the work and we have none staged despite queue requests stacking up. This decreases significantly the amount of work that leaks to the backup pools. - The can_roll function fails inappropriately in stale_work. - Only put the message that a pool is down if not pinging it every minute. This prevents cgminer from saying pool down at 1 minute intervals unless in debug mode. - Free all work in one place allowing us to perform actions on it in the future. - Remove the extra shift in the output code which was of dubious benefit. In fact in cgminer's implementation, removing this caused a miniscule speedup. - Test each work item to see if it can be rolled instead of per-pool and roll whenever possible, adhering to the 60 second timeout. This makes the period after a longpoll have smaller dips in throughput, as well as requiring less getworks overall thus increasing efficiency. - Stick to rolling only work from the current pool unless we're in load balance mode or lagging to avoid aggressive rolling imitating load balancing. - If a work item has had any mining done on it, don't consider it discarded work. CGMiner Version 1.5.3 - July 30, 2011 - Significant work went into attempting to make the thread restart code robust to identify sick threads, tag them SICK after 1 minute, then DEAD after 5 minutes of inactivity and try to restart them. Instead of re-initialising the GPU completely, only a new cl context is created to avoid hanging the rest of the GPUs should the dead GPU be hung irrevocably. - Use correct application name in syslog. - Get rid of extra line feeds. - Use pkg-config to check for libcurl version - Implement per-thread getwork count with proper accounting to not over-account queued items when local work replaces it. - Create a command queue from the program created from source which allows us to flush the command queue in the hope it will not generate a zero sized binary any more. - Be more willing to get work from the backup pools if the work is simply being queued faster than it is being retrieved. CGMiner Version 1.5.2 - July 28, 2011 - Restarting a hung GPU can hang the rest of the GPUs so just declare it dead and provide the information in the status. - The work length in the miner thread gets smaller but doesn't get bigger if it's under 1 second. This could end up leading to CPU under-utilisation and lower and lower hash rates. Fix it by increasing work length if it drops under 1 second. - Make the "quiet" mode still update the status and display errors, and add a new --real-quiet option which disables all output and can be set once while running. - Update utility and efficiency figures when displaying them. - Some Intel HD graphics support the opencl commands but return errors since they don't support opencl. Don't fail with them, just provide a warning and disable GPU mining. - Add http:// if it's not explicitly set for URL entries. - Log to the output file at any time with warnings and errors, instead of just when verbose mode is on. - Display the correct current hash as per blockexplorer, truncated to 16 characters, with just the time. CGMiner Version 1.5.1 - July 27, 2011 - Two redraws in a row cause a crash in old libncurses so just do one redraw using the main window. - Don't adjust hash_div only up for GPUs. Disable hash_div adjustment for GPUs. - Only free the thread structures if the thread still exists. - Update both windows separately, but not at the same time to prevent the double refresh crash that old libncurses has. Do the window resize check only when about to redraw the log window to minimise ncurses cpu usage. - Abstract out the decay time function and use it to make hash_div a rolling average so it doesn't change too abruptly and divide work in chunks large enough to guarantee they won't overlap. - Sanity check to prove locking. - Don't take more than one lock at a time. - Make threads report out when they're queueing a request and report if they've failed. - Make cpu mining work submission asynchronous as well. - Properly detect stale work based on time from staging and discard instead of handing on, but be more lax about how long work can be divided for up to the scantime. - Do away with queueing work separately at the start and let each thread grab its own work as soon as it's ready. - Don't put an extra work item in the queue as each new device thread will do so itself. - Make sure to decrease queued count if we discard the work. - Attribute split work as local work generation. - If work has been cloned it is already at the head of the list and when being reinserted into the queue it should be placed back at the head of the list. - Dividing work is like the work is never removed at all so treat it as such. However the queued bool needs to be reset to ensure we *can* request more work even if we didn't initially. - Make the display options clearer. - Add debugging output to tq_push calls. - Add debugging output to all tq_pop calls. CGMiner Version 1.5.0 - July 26, 2011 - Increase efficiency of slow mining threads such as CPU miners dramatically. Do this by detecting which threads cannot complete searching a work item within the scantime and then divide up a work item into multiple smaller work items. Detect the age of the work items and if they've been cloned before to prevent doing the same work over. If the work is too old to be divided, then see if it can be time rolled and do that to generate work. This dramatically decreases the number of queued work items from a pool leading to higher overall efficiency (but the same hashrate and share submission rate). - Don't request work too early for CPUs as CPUs will scan for the full opt_scantime anyway. - Simplify gpu management enable/disable/restart code. - Implement much more accurate rolling statistics per thread and per gpu and improve accuracy of rolling displayed values. - Make the rolling log-second average more accurate. - Add a menu to manage GPUs on the fly allowing you to enable/disable GPUs or try restarting them. - Keep track of which GPUs are alive versus enabled. - Start threads for devices that are even disabled, but don't allow them to start working. - The last pool is when we are low in total_pools, not active_pools. - Make the thread restart do a pthread_join after disabling the device, only re-enabling it if we succeed in restarting the thread. Do this from a separate thread so as to not block any other code.This will allow cgminer to continue even if one GPU hangs. - Try to do every curses manipulation under the curses lock. - Only use the sockoptfunction if the version of curl is recent enough. CGMiner Version 1.4.1 - July 24, 2011 - Do away with GET for dealing with longpoll forever. POST is the one that works everywhere, not the other way around. - Detect when the primary pool is lagging and start queueing requests on backup pools if possible before needing to roll work. - Load balancing puts more into the current pool if there are disabled pools. Fix. - Disable a GPU device should the thread fail to init. - Out of order command queue may fail on osx. Try without if it fails. - Fix possible dereference on blank inputs during input_pool. - Defines missing would segfault on --help when no sse mining is built in. - Revert "Free up resources/stale compilers." - didn't help. - Only try to print the status of active devices or it would crash. - Some hardware might benefit from the less OPS so there's no harm in leaving kernel changes that do that apart from readability of the code. CGMiner Version 1.4.0 - July 23, 2011 - Feature upgrade: Add keyboard input during runtime to allow modification of and viewing of numerous settings such as adding/removing pools, changing multipool management strategy, switching pools, changing intensiy, verbosity, etc. with a simple keypress menu system. - Free up resources/stale compilers. - Kernels are safely flushed in a way that allows out of order execution to work. - Sometimes the cl compiler generates zero sized binaries and only a reboot seems to fix it. - Don't try to stop/cancel threads that don't exist. - Only set option to show devices and exit if built with opencl support. - Enable curses earlier and exit with message in main for messages to not be lost in curses windows. - Make it possible to enter server credentials with curses input if none are specified on the command line. - Abstract out a curses input function and separate input pool function to allow for live adding of pools later. - Remove the nil arguments check to allow starting without parameters. - Disable/enable echo & cbreak modes. - Add a thread that takes keyboard input and allow for quit, silent, debug, verbose, normal, rpc protocol debugging and clear screen options. - Add pool option to input and display current pool status, pending code to allow live changes. - Add a bool for explicit enabling/disabling of pools. - Make input pool capable of bringing up pools while running. - Do one last check of the work before submitting it. - Implement the ability to live add, enable, disable, and switch to pools. - Only internally test for block changes when the work matches the current pool to prevent interleaved block change timing on multipools. - Display current pool management strategy to enable changing it on the fly. - The longpoll blanking of the current_block data may not be happening before the work is converted and appears to be a detected block change. Blank the current block be - Make --no-longpoll work again. - Abstract out active pools count. - Allow the pool strategy to be modified on the fly. - Display pool information on the fly as well. - Add a menu and separate out display options. - Clean up the messy way the staging thread communicates with the longpoll thread to determine who found the block first. - Make the input windows update immediately instead of needing a refresh. - Allow log interval to be set in the menu. - Allow scan settings to be modified at runtime. - Abstract out the longpoll start and explicitly restart it on pool change. - Make it possible to enable/disable longpoll. - Set priority correctly on multipools. Display priority and alive/dead information in display_pools. - Implement pool removal. - Limit rolltime work generation to 10 iterations only. - Decrease testing log to info level. - Extra refresh not required. - With huge variation in GPU performance, allow intensity to go from -10 to +10. - Tell getwork how much of a work item we're likely to complete for future splitting up of work. - Remove the mandatory work requirement at startup by testing for invalid work being passed which allows for work to be queued immediately. This also removes the requirem - Make sure intensity is carried over to thread count and is at least the minimum necessary to work. - Unlocking error on retry. Locking unnecessary anyway so remove it. - Clear log window from consistent place. No need for locking since logging is disabled during input. - Cannot print the status of threads that don't exist so just queue enough work for the number of mining threads to prevent crash with -Q N. - Update phatk kernel to one with new parameters for slightly less overhead again. Make the queue kernel parameters call a function pointer to select phatk or poclbm. - Make it possible to select the choice of kernel on the command line. - Simplify the output part of the kernel. There's no demonstrable advantage from more complexity. - Merge pull request #18 from ycros/cgminer - No need to make leaveok changes win32 only. - Build support in for all SSE if possible and only set the default according to machine capabilities. - Win32 threading and longpoll keepalive fixes. - Win32: Fix for mangled output on the terminal on exit. CGMiner Version 1.3.1 - July 20, 2011 - Feature upgrade; Multiple strategies for failover. Choose from default which now falls back to a priority order from 1st to last, round robin which only changes pools when one is idle, rotate which changes pools at user-defined intervals, and load-balance which spreads the work evenly amongst all pools. - Implement pool rotation strategy. - Implement load balancing algorithm by rotating requests to each pool. - Timeout on failed discarding of staged requests. - Implement proper flagging of idle pools, test them with the watchdog thread, and failover correctly. - Move pool active test to own function. - Allow multiple strategies to be set for multipool management. - Track pool number. - Don't waste the work items queued on testing the pools at startup. - Reinstate the mining thread watchdog restart. - Add a getpoll bool into the thread information and don't restart threads stuck waiting on work. - Rename the idlenet bool for the pool for later use. - Allow the user/pass userpass urls to be input in any order. - When json rpc errors occur they occur in spits and starts, so trying to limit them with the comms error bool doesn't stop a flood of them appearing. - Reset the queued count to allow more work to be queued for the new pool on pool switch. CGMiner Version 1.3.0 - July 19, 2011 - Massive infrastructure update to support pool failover. - Accept multiple parameters for url, user and pass and set up structures of pool data accordingly. - Probe each pool for what it supports. - Implement per pool feature support according to rolltime support as advertised by server. - Do switching automatically based on a 300 second timeout of locally generated work or 60 seconds of no response from a server that doesn't support rolltime. - Implement longpoll server switching. - Keep per-pool data and display accordingly. - Make sure cgminer knows how long the pool has actually been out for before deeming it a prolonged outage. - Fix bug with ever increasing staged work in 1.2.8 that eventually caused infinite rejects. - Make warning about empty http requests not show by default since many servers do this regularly. CGMiner Version 1.2.8 - July 18, 2011 - More OSX build fixes. - Add an sse4 algorithm to CPU mining. - Fix CPU mining with other algorithms not working. - Rename the poclbm file to ensure a new binary is built since. - We now are guaranteed to have one fresh work item after a block change and we should only discard staged requests. - Don't waste the work we retrieve from a longpoll. - Provide a control lock around global bools to avoid racing on them. - Iterating over 1026 nonces when confirming data from the GPU is old code and unnecessary and can lead to repeats/stales. - The poclbm kernel needs to be updated to work with the change to 4k sized output buffers. - longpoll seems to work either way with post or get but some servers prefer get so change to httpget. CGMiner Version 1.2.7 - July 16, 2011 - Show last 8 characters of share submitted in log. - Display URL connected to and user logged in as in status. - Display current block and when it was started in the status line. - Only pthread_join the mining threads if they exist as determined by pthread_cancel and don't fail on pthread_cancel. - Create a unique work queue for all getworks instead of binding it to thread 0 to avoid any conflict over thread 0's queue. - Clean up the code to make it clear it's watchdog thread being messaged to restart the threads. - Check the current block description hasn't been blanked pending the real new current block data. - Re-enable signal handlers once the signal has been received to make it possible to kill cgminer if it fails to shut down. - Disable restarting of CPU mining threads pending further investigation. - Update longpoll messages. - Add new block data to status line. - Fix opencl tests for osx. - Only do local generation of work if the work item is not stale itself. - Check for stale work within the mining threads and grab new work if positive. - Test for idle network conditions and prevent threads from being restarted by the watchdog thread under those circumstances. - Make sure that local work generation does not continue indefinitely by stopping it after 10 minutes. - Tweak the kernel to have a shorter path using a 4k buffer and a mask on the nonce value instead of a compare and loop for a shorter code path. - Allow queue of zero and make that default again now that we can track how work is being queued versus staged. This can decrease reject rates. - Queue precisely the number of mining threads as longpoll_staged after a new block to not generate local work. CGMiner Version 1.2.6 - July 15, 2011 - Put a current system status line beneath the total work status line - Fix a counting error that would prevent cgminer from correctly detecting situations where getwork was failing - this would cause stalls sometimes unrecoverably. - Limit the maximum number of requests that can be put into the queue which otherwise could get arbitrarily long during a network outage. - Only count getworks that are real queue requests. CGMiner Version 1.2.5 - July 15, 2011 - Conflicting -n options corrected - Setting an intensity with -I disables dynamic intensity setting - Removed option to manually disable dynamic intensity - Improve display output - Implement signal handler and attempt to clean up properly on exit - Only restart threads that are not stuck waiting on mandatory getworks - Compatibility changes courtesy of Ycros to build on mingw32 and osx - Explicitly grab first work item to prevent false positive hardware errors due to working on uninitialised work structs - Add option for non curses --text-only output - Ensure we connect at least once successfully before continuing to retry to connect in case url/login parameters were wrong - Print an executive summary when cgminer is terminated - Make sure to refresh the status window CGMiner Versions -> 1.2.4 - Con Kolivas - July 2011.
