Generalize the submission helpers so they act on a whole struct v3d_submit (the entire job chain) rather than on individual jobs and a drm_exec. This lets a submission of several chained jobs be locked, fenced, and finalized as a single unit, and is the groundwork for collapsing the indirect CSD path into one chain. The following helpers were generalized: - v3d_lookup_bos() - v3d_lock_bo_reservations() (renamed to v3d_submit_lock_reservations()): - v3d_attach_fences_and_unlock_reservation() - v3d_setup_csd_jobs_and_bos() Now, the locking helper now iterates over all jobs and locks the union of their BOs under one DRM exec, using DRM_EXEC_IGNORE_DUPLICATES to tolerate shared BO references. The fence-attach helper similarly walks every job and attaches the chain's last fence to all touched BOs. Also, v3d_submit_jobs() becomes the single submit-and-finalize entry point and callers no longer need to open-code fence attachment, reservation unlocking, etc. Update CL/TFU/CSD/CPU ioctls to use the new helper signatures. The CPU ioctl still uses two struct v3d_submit instances (one for the CPU job, one for the indirect CSD jobs) and keeps its manual two-pass fence-attach flow. Converting the indirect CSD path into the unified chain is done in the next commit. No functional change.
