drm/ttm: rename ttm_mem_reg to ttm_resource.

2020-08-06T03:19:21Z

This name better reflects what the object does. I didn't rename all the pointers it seemed too messy.

Pull hmm updates from Jason Gunthorpe: "This is another round of bug fixing and cleanup. This time the focus is on the driver pattern to use mmu notifiers to monitor a VA range. This code is lifted out of many drivers and hmm_mirror directly into the mmu_notifier core and written using the best ideas from all the driver implementations. This removes many bugs from the drivers and has a very pleasing diffstat. More drivers can still be converted, but that is for another cycle. - A shared branch with RDMA reworking the RDMA ODP implementation - New mmu_interval_notifier API. This is focused on the use case of monitoring a VA and simplifies the process for drivers - A common seq-count locking scheme built into the mmu_interval_notifier API usable by drivers that call get_user_pages() or hmm_range_fault() with the VA range - Conversion of mlx5 ODP, hfi1, radeon, nouveau, AMD GPU, and Xen GntDev drivers to the new API. This deletes a lot of wonky driver code. - Two improvements for hmm_range_fault(), from testing done by Ralph" * tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: mm/hmm: remove hmm_range_dma_map and hmm_range_dma_unmap mm/hmm: make full use of walk_page_range() xen/gntdev: use mmu_interval_notifier_insert mm/hmm: remove hmm_mirror and related drm/amdgpu: Use mmu_interval_notifier instead of hmm_mirror drm/amdgpu: Use mmu_interval_insert instead of hmm_mirror drm/amdgpu: Call find_vma under mmap_sem nouveau: use mmu_interval_notifier instead of hmm_mirror nouveau: use mmu_notifier directly for invalidate_range_start drm/radeon: use mmu_interval_notifier_insert RDMA/hfi1: Use mmu_interval_notifier_insert for user_exp_rcv RDMA/odp: Use mmu_interval_notifier_insert() mm/hmm: define the pre-processor related parts of hmm.h even if disabled mm/hmm: allow hmm_range to be used with a mmu_interval_notifier or hmm_mirror mm/mmu_notifier: add an interval tree notifier mm/mmu_notifier: define the header pre-processor parts even if disabled mm/hmm: allow snapshot of the special zero page

drm/amdgpu: Use mmu_interval_insert instead of hmm_mirror

2019-11-23T23:56:45Z

Remove the interval tree in the driver and rely on the tree maintained by the mmu_notifier for delivering mmu_notifier invalidation callbacks. For some reason amdgpu has a very complicated arrangement where it tries to prevent duplicate entries in the interval_tree, this is not necessary, each amdgpu_bo can be its own stand alone entry. interval_tree already allows duplicates and overlaps in the tree. Also, there is no need to remove entries upon a release callback, the mmu_interval API safely allows objects to remain registered beyond the lifetime of the mm. The driver only has to stop touching the pages during release.
