2021-11-05drm/amdgpu: Fix dangling kfd_bo pointer for shared BOsFelix Kuehling1-2/+2
If a kfd_bo was shared (e.g. a dmabuf export), the original kfd_bo may be freed when the amdgpu_bo still lives on. Free the kfd_bo struct in the release_notify callback then the amdgpu_bo is freed.

2021-10-28drm/amdkfd: Separate pinned BOs destruction from general routineLang Yu1-0/+2
Currently, all kfd BOs use same destruction routine. But pinned BOs are not unpinned properly.

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.

In order to surface the ASIC revision to user level, we want to put it into the HSA topology. This can be because different ASIC revisions may require user-level software to do different things (e.g. patch code for things that are changed in later hardware revisions). The ASIC revision from the hardware is maximum of 4 bits at this time, so put it into 4 of the open bits in the HSA capability.

2020-02-12drm/amdkfd: refactor runtime pm for bacoRajneesh Bhardwaj1-4/+4
So far the kfd driver implemented same routines for runtime and system wide suspend and resume (s2idle or mem). During system wide suspend the kfd aquires an atomic lock that prevents any more user processes to create queues and interact with kfd driver and amd gpu. This mechanism created problem when amdgpu device is runtime suspended with BACO enabled. Any application that relies on kfd driver fails to load because the driver reports a locked kfd device since gpu is runtime suspended. However, in an ideal case, when gpu is runtime suspended the kfd driver should be able to: - auto resume amdgpu driver whenever a client requests compute service - prevent runtime suspend for amdgpu while kfd is in use This change refactors the amdgpu and amdkfd drivers to support BACO and runtime power management.

2020-01-16drm/amdgpu: GPU TLB flush API moved to amdgpu_amdkfdAlex Sierra1-0/+2
[Why] TLB flush method has been deprecated using kfd2kgd interface. This implementation is now on the amdgpu_amdkfd API. [How] TLB flush functions now implemented in amdgpu_amdkfd.

2019-09-13drm/amdgpu: Disable page faults while reading user wptrsFelix Kuehling1-0/+8
These wptrs must be pinned and GPU accessible when this is called from hqd_load functions. So they should never fault. This resolves a circular lock dependency issue involving four locks including the DQM lock and mmap_sem.

2019-09-13drm/amdgpu: Determing PTE flags separately for each mapping (v3)Felix Kuehling1-1/+1
The same BO can be mapped with different PTE flags by different GPUs. Therefore determine the PTE flags separately for each mapping instead of storing them in the KFD buffer object. Add a helper function to determine the PTE flags to be extended with ASIC and memory-type-specific logic in subsequent commits. v2: Split Arcturus-specific MTYPE changes into separate commit v3: Fix return type of get_pte_flags to uint64_t Signed-off-by: Felix Kuehling <[email protected]> Acked-by: Christian König <[email protected]> Reviewed-by: Shaoyun Liu <[email protected]> Signed-off-by: Alex Deucher <[email protected]>
