Subject: [Intel-gfx] [PATCH] drm/i915/display: Defeature PSR2 for RKL and ADL-S
Date: Thu,  8 Apr 2021 14:42:05 -0700	[thread overview]
Message-ID: <20210408214205.327704-1-jose.souza@intel.com> (raw)

PSR2 is defeatured for RKL and ADL-S, no important power impact as
those are desktop CPUs and PSR2 was not even enabled by default yet
in platforms without PSR2 HW tracking.
