Subject: [PATCH 09/33] drm/amd/display: Defer GAMCOR and DSCL power down sequence to vupdate
Date: Sun, 24 Oct 2021 09:31:17 -0400 [thread overview]
Message-ID: <20211024133141.239861-10-Rodrigo.Siqueira@amd.com> (raw)
In-Reply-To: <20211024133141.239861-1-Rodrigo.Siqueira@amd.com>
From: Michael Strauss <michael.strauss@amd.com>
[WHY]
Every other CM LUT power down sequence is deferred to next vupdate as
memory powerdown updates immediately while selecting LUTs is double
buffered. Previous update to defer LUT power down missed GAMCOR and
DSCL, causing some visible flicker when entering/exiting fullscreen
video playback.
[HOW]
Update dpp deferred update loop to check for valid DPPs in res_pool
instead of referencing dcn_ip which turns out to not be populated during
runtime. Move GAMCOR and DSCL powerdown to dpp deferred updates.
