Subject: [PATCH AUTOSEL 5.10 32/47] drm/msm/a5xx: Remove overwriting A5XX_PC_DBG_ECO_CNTL register
Date: Tue, 2 Mar 2021 06:56:31 -0500 [thread overview]
Message-ID: <20210302115646.62291-32-sashal@kernel.org> (raw)
In-Reply-To: <20210302115646.62291-1-sashal@kernel.org>
From: AngeloGioacchino Del Regno <angelogioacchino.delregno@somainline.org>
[ Upstream commit 8f03c30cb814213e36032084a01f49a9e604a3e3 ]
The PC_DBG_ECO_CNTL register on the Adreno A5xx family gets
programmed to some different values on a per-model basis.
At least, this is what we intend to do here;
Unfortunately, though, this register is being overwritten with a
static magic number, right after applying the GPU-specific
configuration (including the GPU-specific quirks) and that is
effectively nullifying the efforts.
Let's remove the redundant and wrong write to the PC_DBG_ECO_CNTL
register in order to retain the wanted configuration for the
target GPU.
