Monk or perhaps Felix,
Do you by any chance know why the CS ioctl returns -EINVAL for all compute
submissions if num_kcq <= 4 and what could cause that?
If not, is there any way to disable mid-IB preemption for compute?
Thanks,
Marek

what:
the MQD's save and restore of KCQ (kernel compute queue)
cost lots of clocks during world switch which impacts a lot
to multi-VF performance
how:
introduce a paramter to control the number of KCQ to avoid
performance drop if there is no kernel compute queue needed
notes:
this paramter only
