Lock all BOs used in gpuva ops and validate all BOs in a single step during the VM bind IOCTL. This help with the transition to making all gpuva ops in a VM bind IOCTL a single atomic job which is required for proper error handling. v2: - Better commit message (Oak) - s/op_lock/op_lock_and_prep, few other renames too (Oak) - Use DRM_EXEC_IGNORE_DUPLICATES flag in drm_exec_init (local testing) - Do not reserve slots in locking step (direction based on series from Thomas) v3: - Validate BO if is immediate set (Oak) Cc: Oak Zeng <oak.zeng@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: Oak Zeng <oak.zeng@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240425045513.1913039-2-matthew.brost@intel.com
