drm/amdgpu: move buffer funcs setting up a level

2023-10-26T20:04:24+00:00

Rather than doing this in the IP code for the SDMA paging engine, move it up to the core device level init level. This should fix the scheduler init ordering. v2: drop extra parens v3: drop SDMA helpers v4: Added a Fixes tag because amdgpu dereferences an uninitialized scheduler without this patch, and this patch fixes this.

drm/amdgpu/sdma: set sched.ready status after ring/IB test in sdma

2023-06-09T14:57:07+00:00

sched.ready is nothing with ring initialization, it needs to set to be true after ring/IB test in amdgpu_ring_test_helper to tell the ring is ready for submission. Signed-off-by: Guchun Chen Acked-by: Alex Deucher Signed-off-by: Alex Deucher
