drm/amdkfd: Enable GFX11 usermode queue oversubscription
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.
