Subject: [PATCH] drm/amdgpu/gfx10,11: use memcpy_to/fromio for MQDs
Date: Thu, 26 Oct 2023 14:56:08 -0400 [thread overview]
Message-ID: <20231026185609.28627-1-alexander.deucher@amd.com> (raw)
Since they were moved to VRAM, we need to use the IO
variants of memcpy.
Fixes: 1cfb4d612127 ("drm/amdgpu: put MQDs in VRAM")
