A CPU job is a type of job that performs operations that requires CPU intervention. An indirect CSD job is a job that, when executed in the queue, will map the indirect buffer, read the dispatch parameters, and submit a regular dispatch. Therefore, it is a job that needs CPU intervention. So, create a user extension for the CPU job that enables the creation of an indirect CSD. This user extension will allow the creation of a CSD job linked to a CPU job. The CPU job will wait for the indirect CSD job dependencies and, once they are signaled, it will update the CSD job parameters. Co-developed-by:
