The V3D engine has various hardware counters which might be interesting to userspace performance analysis tools. Expose new ioctls to create/destroy a performance monitor object and query the counter values of this perfmance monitor. Note that a perfomance monitor is given an ID that is only valid on the file descriptor it has been allocated from. A performance monitor can be attached to a CL submission and the driver will enable HW counters for this request and update the performance monitor values at the end of the job.
