Instead do the move to SYSTEM and back to GTT when mapping these attachments to ensure the SG table gets updated after evictions.

2022-12-20drm/amdkfd: Fix double release compute pasidPhilip Yang
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.

It is to resolve a regression, which fails to allocate VRAM due to no free memory in application, the reason is we add check of vram_pin_size for memory limit, and application is pinning the memory for Peerdirect, KFD should not count it in memory limit.

2022-11-09drm/amdgpu: Set MTYPE in PTE based on BO flagsFelix Kuehling
The same BO may need different MTYPEs and SNOOP flags in PTEs depending on its current location relative to the mapping GPU. Setting MTYPEs from clients ahead of time is not practical for coherent memory sharing. Instead determine the correct MTYPE for the desired coherence model and current BO location when updating the page tables. To maintain backwards compatibility with MTYPE-selection in AMDGPU_VA_OP_MAP, the coherence-model-based MTYPE selection is only applied if it chooses an MTYPE other than MTYPE_NC (the default). Add two AMDGPU_GEM_CREATE_... flags to indicate the coherence model. The default if no flag is specified is non-coherent (i.e. coarse-grained coherent at dispatch boundaries). Update amdgpu_amdkfd_gpuvm.c to use this new method to choose the correct MTYPE depending on the current memory location. v2: * check that bo is not NULL (e.g. PRT mappings) * Fix missing ~ bitmask in gmc_v11_0.c v3: * squash in "drm/amdgpu: Inherit coherence flags on dmabuf import" Suggested-by: Christian König <christian.koenig@amd.com> Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
