2022-06-23drm/amdkfd: Enable GFX11 usermode queue oversubscriptionGraham Sider1-0/+48
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.

MMIO/DOORBELL BOs' backing resources(bus address resources that are used to talk to the GPU) are not managed by GTT manager, but they are counted by GTT manager. That makes no sense. With AMDGPU_GEM_CREATE_PREEMPTIBLE flag, such BOs will be managed by PREEMPT manager(for preemptible contexts, e.g., KFD). Then they won't be evicted and don't need to be pinned as well. But we still leave these BOs pinned to indicate that the underlying resource never moves.
