drm/v3d: add multiple syncobjs support
Using the generic extension from the previous patch, a specific multisync extension enables more than one in/out binary syncobj per job submission. Arrays of syncobjs are set in struct drm_v3d_multisync, that also cares of determining the stage for sync (wait deps) according to the job queue. v2: - subclass the generic extension struct (Daniel) - simplify adding dependency conditions to make understandable (Iago) v3: - fix conditions to consider single or multiples in/out_syncs (Iago) - remove irrelevant comment (Iago) Signed-off-by: Melissa Wen <mwen@igalia.com> Reviewed-by: Iago Toral Quiroga <itoral@igalia.com> Signed-off-by: Melissa Wen <melissa.srw@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/ffd8b2e3dd2e0c686db441a0c0a4a0181ff85328.1633016479.git.mwen@igalia.com
