Subject: [PATCH RESEND 0/2] drm/msm/dpu: use full scale alpha in generic code
Date: Tue, 18 Nov 2025 16:51:39 +0200 [thread overview]
Message-ID: <20251118-dpu-rework-alpha-v1-0-293d39402b59@oss.qualcomm.com> (raw)
Both _dpu_crtc_setup_blend_cfg() and setup_blend_config_alpha()
callbacks embed knowledge about platform's alpha range (8-bit or
10-bit). Make _dpu_crtc_setup_blend_cfg() use full 16-bit values for
alpha and reduce alpha only in DPU-specific callbacks.
