[PATCH 1/2] drm/i915: Drop stray clearing of rps->last_adj

[PATCH 1/2] drm/i915: Drop stray clearing of rps->last_adj

[Chris Wilson]

We used to reset last_adj to 0 on crossing a power domain boundary, to
slow down our rate of change. However, commit 60548c554be2 ("drm/i915:
Interactive RPS mode") accidentally caused it to be reset on every
frequency update, nerfing the fast response granted by the slow start
algorithm.

Fixes: 60548c554be2 ("drm/i915: Interactive RPS mode")

[PATCH 2/2] drm/i915: Dampen RPS slow start

[Chris Wilson]

Currently, we note congestion for the slow start ramping up of RPS only
when we overshoot the target workload and have to reverse direction for
our reclocking. That is, if we have a period where the current GPU
frequency is enough to sustain the workload within our target
utilisation, we should not trigger any RPS EI interrupts, and then may
continue again with the previous last_adj after multiple periods causing
us to dramatically overreact. To prevent us not noticing a period where
the system is behaving correctly, we can schedule an extra interrupt
that will not be associated with either an up or down event causing to
reset last_adj back to zero, cancelling the slow start due to the
congestion.

The original plan was to use UP/DOWN EI as the danger is that the two
evaluation intervals are not aligned and so not we may falsely detect
congestion in the middle of the ramp. The reason I didn't was we do use
UP_EI_EXPIRED for the manual calcs for vlv.

Hmm, still it would be better not to mix the wrong EI.

[PATCH] drm/i915: Dampen RPS slow start

[Chris Wilson]

Currently, we note congestion for the slow start ramping up of RPS only
when we overshoot the target workload and have to reverse direction for
our reclocking. That is, if we have a period where the current GPU
frequency is enough to sustain the workload within our target
utilisation, we should not trigger any RPS EI interrupts, and then may
continue again with the previous last_adj after multiple periods causing
us to dramatically overreact. To prevent us not noticing a period where
the system is behaving correctly, we can schedule an extra interrupt
that will not be associated with either an up or down event causing to
reset last_adj back to zero, cancelling the slow start due to the
congestion.
