-Subject: drm/amdgpu/gfx9: manually control gfxoff for CS on RV
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-From: Alex Deucher <alexander.deucher@amd.com>
-
-commit b35eb9128ebeec534eed1cefd6b9b1b7282cf5ba upstream.
-
-When mesa started using compute queues more often
-we started seeing additional hangs with compute queues.
-Disabling gfxoff seems to mitigate that. Manually
-control gfxoff and gfx pg with command submissions to avoid
-any issues related to gfxoff. KFD already does the same
-thing for these chips.
-
-v2: limit to compute
-v3: limit to APUs
-v4: limit to Raven/PCO
-v5: only update the compute ring_funcs
-v6: Disable GFX PG
-v7: adjust order
