[igt-dev] [PATCH i-g-t v2 6/6] tests/v3d_submit_cl: Create test for V3D's Submit CL IOCTL

Thu Jan 12 13:15:34 UTC 2023
Add eighteen igt_subtests for the DRM_IOCTL_V3D_SUBMIT_CL, which ensures
that improper parameters return an errno and test multisync and simple
sync abilities. For most of the subtests, the noop job is the base of
the submission, as it is one of the simplest jobs possible, allowing it
to test the synchronization abilities of the V3D.
