HMM interval notifier callback notify CPU page table will be updated, stop process queues if the updated address belongs to svm range registered in process svms objects tree. Scheduled restore work to update GPU page table using new pages address in the updated svm range. The restore worker flushes any deferred work to make sure it restores an up-to-date svm_range_list.

It will be used by kfd to map svm range to GPU, because svm range does not have amdgpu_bo and bo_va, cannot use amdgpu_bo_update interface, use amdgpu vm update interface directly. Signed-off-by:

When application explicitly call unmap or unmap from mmput when application exit, driver will receive MMU_NOTIFY_UNMAP event to remove svm range from process svms object tree and list first, unmap from GPUs (in the following patch). Split the svm ranges to handle partial unmapping of svm ranges. To avoid deadlocks, updating MMU notifiers, range lists and interval trees is done in a deferred worker. New child ranges are attached to their parent range's child_list until the worker can update the svm_range_list. svm_range_set_attr flushes deferred work and takes the mmap_write_lock to guarantee that it has an up-to-date svm_range_list.

svm range structure stores the range start address, size, attributes, flags, prefetch location and gpu bitmap which indicates which GPU this range maps to. Same virtual address is shared by CPU and GPUs. Process has svm range list which uses both interval tree and list to store all svm ranges registered by the process. Interval tree is used by GPU vm fault handler and CPU page fault handler to get svm range structure from the specific address. List is used to scan all ranges in eviction restore work. No overlap range interval [start, last] exist in svms object interval tree. If process registers new range which has overlap with old range, the old range split into 2 ranges depending on the overlap happens at head or tail part of old range. Apply attributes preferred location, prefetch location, mapping flags, migration granularity to svm range, store mapping gpu index into bitmap. Signed-off-by:

Add svm (shared virtual memory) ioctl data structure and API definition. The svm ioctl API is designed to be extensible in the future. All operations are provided by a single IOCTL to preserve ioctl number space. The arguments structure ends with a variable size array of attributes that can be used to set or get one or multiple attributes. Signed-off-by:

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.

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. Signed-off-by:

Fix the following issues with SDMA RAS error reporting: 1. Read the EDC_COUNTER2 register also to fetch error counts for all sub-blocks in SDMA. 2. SDMA RAS on Aldebaran suports single-bit uncorrectable errors only. So, report error count in UE count instead of CE count. Signed-off-by:
