2022-12-20drm/amdkfd: Fix double release compute pasidPhilip Yang1-1/+3
If kfd_process_device_init_vm returns failure after vm is converted to compute vm and vm->pasid set to compute pasid, KFD will not take pdd->drm_file reference. As a result, drm close file handler maybe called to release the compute pasid before KFD process destroy worker to release the same pasid and set vm->pasid to zero, this generates below WARNING backtrace and NULL pointer access. Add helper amdgpu_amdkfd_gpuvm_set_vm_pasid and call it at the last step of kfd_process_device_init_vm, to ensure vm pasid is the original pasid if acquiring vm failed or is the compute pasid with pdd->drm_file reference taken to avoid double release same pasid. amdgpu: Failed to create process VM object ida_free called for id=32770 which is not allocated.

2022-06-23drm/amdkfd: Enable GFX11 usermode queue oversubscriptionGraham Sider1-0/+2
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.

2021-04-20drm/amdkfd: add svm_bo reference for eviction fenceAlex Sierra1-1/+3
[why] As part of the SVM functionality, the eviction mechanism used for SVM_BOs is different. This mechanism uses one eviction fence per prange, instead of one fence per kfd_process. [how] A svm_bo reference to amdgpu_amdkfd_fence to allow differentiate between SVM_BO or regular BO evictions. This also include modifications to set the reference at the fence creation call.

2021-04-20drm/amdkfd: set memory limit to avoid OOM with HMM enabledPhilip Yang1-0/+1
HMM migration alloc sizeof(struct page) on system memory for each VRAM page, it is 1GB system memory reserved for 64GB VRAM. To avoid application OOM, increase system memory used size based on VRAM size of all GPUs, then application alloc memory will fail if system memory usage reach the limit.

2021-04-20drm/amdkfd: Allow access for mmapping KFD BOsFelix Kuehling1-1/+2
DRM render node file handles are used for CPU mapping of BOs using mmap by the Thunk. It uses the DRM render node of the GPU where the BO was allocated. DRM allows mmap access automatically when it creates a GEM handle for a BO. KFD BOs don't have GEM handles, so KFD needs to manage access manually. Use drm_vma_node_allow to allow user mode to mmap BOs allocated with kfd_ioctl_alloc_memory_of_gpu through the DRM render node that was used in the kfd_ioctl_acquire_vm call for the same GPU.

2021-04-20drm/amdkfd: Use drm_priv to pass VM from KFD to amdgpuFelix Kuehling1-7/+7
amdgpu_amdkfd_gpuvm_alloc_memory_of_gpu needs the drm_priv to allow mmap to access the BO through the corresponding file descriptor. The VM can also be extracted from drm_priv, so drm_priv can replace the vm parameter in the kfd2kgd interface.
