<pre>Although the fix from GuC perspective is not merged, other patch that is making
Host RPS handle erroneous adjustment properly is merged from
<a href="https://patchwork.freedesktop.org/series/18252/">https://patchwork.freedesktop.org/series/18252/</a>.
Specifically following patch is helping resolve the issue that is merged in
drm-tip:
7e79a68 drm/i915: Set adjustment to zero on Up/Down interrupts if freq is
already max/min
With current available GuC firmware 6.1 for SKL I could verify this fix for
workloads. Scores for 3 runs:
default:
glb_egypt_fixedtime = 129.0 <= 130.0 <= 131.0
gfxbench3_alu_offscreen = 287.9 <= 288.0 <= 288.1
with guc enabled
glb_egypt_fixedtime = 130.0 <= 130.0 <= 130.0
gfxbench3_alu_offscreen = 287.9 <= 288.2 <= 289.5
with fix reverted
glb_egypt_fixedtime = 119.0 <= 119.0 <= 120.0
gfxbench3_alu_offscreen = 254.5 <= 254.5 <= 254.5
If this bug is not gated by GuC submission enabling we can close this.
Hence I am marking this as resolved. Kindly correct if this needs to changed.</pre>
