amdgpu_do_test_moves() is failing because of wrong usable gart size calculation and throwing: [drm:amdgpu_do_test_moves [amdgpu]] *ERROR* 0000000020bdc9f3 bind failed Signed-off-by: Nirmoy Das <nirmoy.das@xxxxxxx> --- This still doesn't work. As per my calculation 1st 4MB of GART is not accounted for in adev->gmc.gart_size - atomic64_read(&adev->gart_pin_size).
The member gart_pin_size should probably be renamed to gtt_pin_size, but since a gtt pin is also automatically visible in the GART that should probably be ok for now.
What am I missing ?
The two 2MB windows in the GART which are used for buffer moves. See AMDGPU_GTT_MAX_TRANSFER_SIZE and AMDGPU_GTT_NUM_TRANSFER_WINDOWS. Regards, Christian.
