Add the first version of the VM_BIND locking document which is intended to be part of the xe driver upstreaming agreement. The document describes and discuss the locking used during exec- functions, evicton and for userptr gpu-vmas. Intention is to be using the same nomenclature as the drm-vm-bind-async.rst. v2: - s/gvm/gpu_vm/g (Rodrigo Vivi) - Clarify the userptr seqlock with a pointer to mm/mmu_notifier.c (Rodrigo Vivi) - Adjust commit message accordingly. - Add SPDX license header. v3: - Large update to align with the drm_gpuvm manager locking - Add "Efficient userptr gpu_vma exec function iteration" section - Add "Locking at bind- and unbind time" section. v4: - Fix tabs vs space errors by untabifying (Rodrigo Vivi) - Minor style fixes and typos (Rodrigo Vivi) - Clarify situations where stale GPU mappings are occurring and how access through these mappings are blocked. (Rodrigo Vivi) - Insert into the toctree in implementation_guidelines.rst v5: - Add a section about recoverable page-faults. - Use local references to other documentation where possible (Bagas Sanjaya) - General documentation fixes and typos (Danilo Krummrich and Boris Brezillon) - Improve the documentation around locks that need to be grabbed from the dm-fence critical section (Boris Brezillon) - Add more references to the DRM GPUVM helpers (Danilo Krummrich and Boriz Brezillon) - Update the rfc/xe.rst document. v6: - Rework wording to improve readability (Boris Brezillon, Rodrigo Vivi, Bagas Sanjaya) - Various minor fixes across the document (Boris Brezillon) Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Danilo Krummrich <dakr@redhat.com> Acked-by: John Hubbard <jhubbard@nvidia.com> # Documentation/core-api/pin_user_pages.rst changes Link: https://patchwork.freedesktop.org/patch/msgid/20231129090637.2629-1-thomas.hellstrom@linux.intel.com |
