-Subject: [PATCH] drm/i915: Use consistent forcewake auto-release timeout
- across kernel configs
-
-Upstream commit fde61b596b994195b9dd83feb325df95d99702ce
-
-Because it is based on jiffies, current implementation releases the
-forcewake at any time between straight away and between 1ms and 10ms,
-depending on the kernel configuration (CONFIG_HZ).
-
-This is probably not what has been desired, since the dynamics of keeping
-parts of the GPU awake should not be correlated with this kernel
-configuration parameter.
-
-Change the auto-release mechanism to use hrtimers and set the timeout to
-1ms with a 1ms of slack. This should make the GPU power consistent
-across kernel configs, and timer slack should enable some timer coalescing
-where multiple force-wake domains exist, or with unrelated timers.
-
-For GlBench/T-Rex this decreases the number of forcewake releases from
-~480 to ~300 per second, and for a heavy combined OGL/OCL test from
-~670 to ~360 (HZ=1000 kernel).
-
-Even though this reduction can be attributed to the average release period
-extending from 0-1ms to 1-2ms, as discussed above, it will make the
-forcewake timeout consistent for different CONFIG_HZ values.
-
-Real life measurements with the above workload has shown that, with this
-patch, both manage to auto-release the forcewake between 2-4 times per
-10ms, even though the number of forcewake gets is dramatically different.
-
-T-Rex requests between 5-10 explicit gets and 5-10 implict gets in each
-10ms period, while the OGL/OCL test requests 250 and 380 times in the same
-period.
-
-The two data points together suggest that the nature of the forwake
-accesses is bursty and that further changes and potential timeout
-extensions, or moving the start of timeout from the first to the last
-automatic forcewake grab, should be carefully measured for power and
-performance effects.
-
-v2:
-  * Commit spelling. (Dave Gordon)
-  * More discussion on numbers in the commit. (Chris Wilson)
