[igt-dev] [PATCH i-g-t v3 0/3] V3D Mixed Job Submission Tests

[Maíra Canal]

Currently, the V3D tests only support CL job submissions, while V3D has also
capabilities for CSD and TFU jobs. Therefore, create tests for
DRM_IOCTL_V3D_SUBMIT_CSD, an ioctl for dispatching compute shader jobs to the
GPU. In order to create a simple CSD job, I hard-coded the pipeline assembly
shader of an empty shader in order to reproduce a shader and be able to create
an acceptable packet that can be sent to the GPU.

So, patch 1 introduces a helper function to submit a minimal CSD job to the GPU,
which will be useful for the tests. The minimal job will use the pipeline
assembly shader of an empty shader. Patches 2-3 will include new tests in the
V3D test suite for DRM_IOCTL_V3D_SUBMIT_CSD and create tests that mix different
types of jobs, in order to evaluate the synchronization between the two types of
jobs. 

v1 -> v2:

- Add a progress bar to the "threaded-job-submission" sub-test (Melissa Wen).
- Fix checkpatch issues.

v2 -> v3:

- Add descriptions to all the public functions added (Kamil Konieczny).
