drm/amdgpu: pass queue size and is_aql_queue to MES

2022-09-27T21:54:12Z

Update mes_v11_api_def.h add_queue API with is_aql_queue parameter. Also re-use gds_size for the queue size (unused for KFD). MES requires the queue size in order to compute the actual wptr offset within the queue RB since it increases monotonically for AQL queues. v2: Make is_aql_queue assign clearer Signed-off-by: Graham Sider Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Enable GFX11 usermode queue oversubscription

2022-06-23T21:22:12Z

Starting with GFX11, MES requires wptr BOs to be GTT allocated/mapped to GART for usermode queues in order to support oversubscription. In the case that work is submitted to an unmapped queue, MES must have a GART wptr address to determine whether the queue should be mapped. This change is accompanied with changes in MES and is applicable for MES_API_VERSION >= 2. v3: - Use amdgpu_vm_bo_lookup_mapping for wptr_bo mapping lookup - Move wptr_bo refcount increment to amdgpu_amdkfd_map_gtt_bo_to_gart - Remove list_del_init from amdgpu_amdkfd_map_gtt_bo_to_gart - Cleanup/fix create_queue wptr_bo error handling v4: - Add MES version shift/mask defines to amdgpu_mes.h - Change version check from MES_VERSION to MES_API_VERSION - Add check in kfd_ioctl_create_queue before wptr bo pin/GART map to ensure bo is a single page.
