This aligns with the uAPI of an array of binds or single bind that results in multiple GPUVA ops to be considered a single atomic operations. The design is roughly: - xe_vma_ops is a list of xe_vma_op (GPUVA op) - each xe_vma_op resolves to 0-3 PT ops - xe_vma_ops creates a single job - if at any point during binding a failure occurs, xe_vma_ops contains the information necessary unwind the PT and VMA (GPUVA) state v2: - add missing dma-resv slot reservation (CI, testing) v4: - Fix TLB invalidation (Paulo) - Add missing xe_sched_job_last_fence_add/test_dep check (Inspection) v5: - Invert i, j usage (Matthew Auld) - Add helper to test and add job dep (Matthew Auld) - Return on anything but -ETIME for cpu bind (Matthew Auld) - Return -ENOBUFS if suballoc of BB fails due to size (Matthew Auld) - s/do/Do (Matthew Auld) - Add missing comma (Matthew Auld) - Do not assign return value to xe_range_fence_insert (Matthew Auld) v6: - s/0x1ff/MAX_PTE_PER_SDI (Matthew Auld, CI) - Check to large of SA in Xe to avoid triggering WARN (Matthew Auld) - Fix checkpatch issues v7: - Rebase - Support more than 510 PTEs updates in a bind job (Paulo, mesa testing) v8: - Rebase Cc: Thomas Hellström <thomas.hellstrom@linux.intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240704041652.272920-5-matthew.brost@intel.com
