From b3c942bb6c32a8ddc1d52ee6bc24b8cf732dddf4 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 26 Oct 2023 14:47:57 -0400 Subject: drm/amdgpu/gfx10,11: use memcpy_to/fromio for MQDs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since they were moved to VRAM, we need to use the IO variants of memcpy.
