Subject: [PATCH] drm/i915/guc/slpc: Apply min softlimit correctly
Date: Fri, 9 Jun 2023 15:02:52 -0700 [thread overview]
Message-ID: <20230609220252.410740-1-vinay.belgaumkar@intel.com> (raw)
We were skipping when min_softlimit was equal to RPn. We need to apply
it rergardless as efficient frequency will push the SLPC min to RPe.
This will break scenarios where user sets a min softlimit < RPe before
reset and then performs a GT reset.
Fixes: 95ccf312a1e4 ("drm/i915/guc/slpc: Allow SLPC to use efficient frequency")
