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 <arg> Set the GPU engine (over)clock in Mhz - one value for all or
separate by commas for per card.
--gpu-fan <arg> Set the GPU fan percentage - one value for all or separate
by commas for per card.
--gpu-memclock <arg> Set the GPU memory (over)clock in Mhz - one value for all
or separate by commas for per card.
--gpu-powertune <arg> Set the GPU powertune percentage - one value for all or
separate by commas for per card.
--gpu-vddc <arg> Set the GPU voltage in Volts - one value for all or separate
by commas for per card.
--temp-hysteresis <arg> Set how much the temperature can fluctuate outside
limits when automanaging speeds (default: 3)
--temp-overheat <arg> Set the overheat temperature when automatically managing
fan and GPU speeds (default: 85)
--temp-target <arg> 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.
Version 1.6.2 - September 2, 2011
- Add --failover-only option to not leak work to backup pools when the primary
