Karol Wachowski 774e7cb503 accel/ivpu: Add dma fence to command buffers only ... Currently job->done_fence is added to every BO handle within a job. If job handle (command buffer) is shared between multiple submits, KMD will add the fence in each of them. Then bo_wait_ioctl() executed on command buffer will exit only when all jobs containing that handle are done. This creates deadlock scenario for user mode driver in case when job handle is added as dependency of another job, because bo_wait_ioctl() of first job will wait until second job finishes, and second job can not finish before first one. Having fences added only to job buffer handle allows user space to execute bo_wait_ioctl() on the job even if it's handle is submitted with other job.
