Subject: [PATCH RFT v3 09/14] drm/msm/a6xx: Resolve the meaning of rgb565_predicator
Date: Sat, 17 May 2025 19:32:43 +0200 [thread overview]
Message-ID: <20250517-topic-ubwc_central-v3-9-3c8465565f86@oss.qualcomm.com> (raw)
In-Reply-To: <20250517-topic-ubwc_central-v3-0-3c8465565f86@oss.qualcomm.com>
From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>
It's supposed to be on when the UBWC encoder version is >= 4.0.
Drop the per-GPU assignments.
