From 03ff6d7238b77e5fb2b85dc5fe01d2db9eb893bd Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 19 Jan 2024 12:23:55 -0500 Subject: drm/amdgpu/gfx10: set UNORD_DISPATCH in compute MQDs This needs to be set to 1 to avoid a potential deadlock in the GC 10.x and newer. On GC 9.x and older, this needs to be set to 0. This can lead to hangs in some mixed graphics and compute workloads. Updated firmware is also required for AQL.
