2023-06-09drm/amdgpu/sdma: set sched.ready status after ring/IB test in sdmaGuchun Chen1-2/+0
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.

2020-04-01drm/amdgpu: stop disable the scheduler during HW finiChristian König1-2/+0
When we stop the HW for example for GPU reset we should not stop the front-end scheduler. Otherwise we run into intermediate failures during command submission. The scheduler should only be stopped in very few cases: 1. We can't get the hardware working in ring or IB test after a GPU reset. 2. The KIQ scheduler is not used in the front-end and should be disabled during GPU reset. 3. In amdgpu_ring_fini() when the driver unloads.

When max_bytes is not 8 bytes aligned and bo size is larger than max_bytes, the last 8 bytes in a ttm node may be left unchanged. For example, on pre SDMA 4.0, max_bytes = 0x1fffff, and the bo size is 0x200000, the problem will happen. In order to fix the problem, we separately store the max nums of PTEs/PDEs a single operation can set in amdgpu_vm_pte_funcs structure, rather than inferring it from bytes limit of SDMA constant fill, i.e. fill_max_bytes. Together with the fix, we replace the hard code value "10" in amdgpu_vm_bo_update_mapping() with the corresponding values from structure amdgpu_vm_pte_funcs.
