2020-04-09drm/amdgpu: rework sched_list generationNirmoy Das1-1/+2
Generate HW IP's sched_list in amdgpu_ring_init() instead of amdgpu_ctx.c. This makes amdgpu_ctx_init_compute_sched(), ring.has_high_prio and amdgpu_ctx_init_sched() unnecessary. This patch also stores sched_list for all HW IPs in one big array in struct amdgpu_device which makes amdgpu_ctx_init_entity() much more leaner. v2: fix a coding style issue do not use drm hw_ip const to populate amdgpu_ring_type enum v3: remove ctx reference and move sched array and num_sched to a struct use num_scheds to detect uninitialized scheduler list v4: use array_index_nospec for user space controlled variables fix possible checkpatch.pl warnings Signed-off-by: Nirmoy Das <nirmoy.das@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2020-04-01drm/amdgpu: stop disable the scheduler during HW finiChristian König1-1/+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.

2017-09-26drm/amdgpu: Fix a bug in amdgpu_fill_buffer()Yong Zhao1-0/+3
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.
