|
|
|
|
|
|
|
|
|
Major feature upgrade - GPU monitoring, (over)clocking and fan control for ATI |
|
|
|
|
GPUs. |
|
|
|
|
|

|
|

|
|
|
|
|
|
|
|
|
- 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. |

|
|
