This is an effort to unify hmmptr (aka system allocator) and userptr code. hmm_range_fault is used to populate a virtual address range for both hmmptr and userptr, instead of hmmptr using hmm_range_fault and userptr using get_user_pages_fast. This also aligns with AMD gpu driver's behavior. In long term, we plan to put some common helpers in this area to drm layer so it can be re-used by different vendors. -v1 use the function with parameter to confirm whether lock is acquired by the caller or needs to be acquired in hmm_range_fault.

Introduce a helper function xe_userptr_populate_range to populate a userptr range. This functions calls hmm_range_fault to read CPU page tables and populate all pfns/pages of this virtual address range. For system memory page, dma-mapping is performed to get a dma-address which can be used later for GPU to access pages. v1: Address review comments: separate a npage_in_range function (Matt) reparameterize function xe_userptr_populate_range function (Matt) move mmu_interval_read_begin() call into while loop (Thomas) s/mark_range_accessed/xe_mark_range_accessed (Thomas) use set_page_dirty_lock (vs set_page_dirty) (Thomas) move a few checking in xe_vma_userptr_pin_pages to hmm.c (Matt) v2: Remove device private page support. Only support system pages for now. use dma-map-sg rather than dma-map-page (Matt/Thomas) v3: Address review comments: Squash patch "drm/xe: Introduce a helper to free sg table" to current patch (Matt) start and end addresses are already page aligned (Matt) Do mmap_read_lock and mmap_read_unlock for hmm_range_fault incase of non system allocator call. (Matt) Drop kthread_use_mm and kthread_unuse_mm. (Matt) No need of kernel-doc for static functions.(Matt) Modify function names. (Matt) Free sgtable incase of dma_map_sgtable failure.(Matt) Modify loop for hmm_range_fault.(Matt) v4: Remove the dummy function for xe_hmm_userptr_populate_range since CONFIG_HMM_MIRROR is needed. (Matt) Change variable names start/end to userptr_start/userptr_end.(Matt) v5: Remove device private page support info from commit message. Since the patch doesn't support device page handling.

This will remove devcoredump from file system and free its resources during driver unload. This fix the driver unload after gpu hang happened, otherwise this it would report that Xe KMD is still in use and it would leave the kernel in a state that Xe KMD can't be unload without a reboot.

We want to have an option to limit the number of the VFs that the PF driver will be able to manage. With this limit set to zero we will also have a way to completely disable the PF functionality.

We may leave pat.ops unset when running on brand new platform or when running as a VF. While the former is unlikely, the latter is valid (future) use case and will cause NPD when someone will try to dump PAT settings by debugfs. It's better to check pointer to pat.ops instead of specific .dump hook, as we have this hook always defined for every .ops variant. Signed-off-by:

On Xe2 dGPU, compression is only supported with VRAM. When copying from VRAM -> system memory the KMD uses mapping with uncompressed PAT so the copy in system memory is guaranteed to be uncompressed. When restoring such buffers from system memory -> VRAM the KMD can't easily know which pages were originally compressed, so we always use uncompressed -> uncompressed here. so this means that there's no need for extra CCS storage on such platforms. v2: More description added to commit message Signed-off-by:

Always capture exec queues on snapshot regardless if exec queue has pending jobs or not. Having jobs or not does indicate whether the exec queue capture is useful. Example bugs that would not be easily detected by skipping capture when pending job list is empty: - Jobs pending on exec queue have dependencies - Leaking exec queue refs - GuC protocol issues (i.e. losing G2H) In addition to above bugs, in general it just useful to see every exec queue registered with the GuC and its state.

Some flags now needed by the compute runtime are brought back in this commit: - DRM_XE_VM_BIND_FLAG_READONLY is used to write protect kernel ISA thus preventing accidental overwrites. - DRM_XE_VM_BIND_FLAG_IMMEDIATE is used to trigger mapping at the time of binding in order to prevent faulting at execution time.
