Subject: [PATCH 1/8] drm/amdgpu: Fix gfx_hqd_mask in mes 12.1
Date: Fri, 20 Mar 2026 16:02:01 -0400	[thread overview]
Message-ID: <20260320200208.1188307-2-Amber.Lin@amd.com> (raw)
In-Reply-To: <20260320200208.1188307-1-Amber.Lin@amd.com>

Same as compute and sdma, gfx_hqd_mask has been initialized properly in
amdgpu_mes_init. set_hw_res should use those initialization accordingly.
Hardcoding it causes the mismatch between driver and MES.
