[Intel-gfx] [PATCH v3 00/16] arb robustness enablers v3

[Mika Kuoppala]

Hi,

I have addressed all the feedback I got from v2 series.

Most notably the interface has changed.

Now those users who don't care about the exact counts can use batch_pending
and batch_active like they would be flags (see i-g-t testcase),
assuming they destroy the context after hang is dealt with.
For those users who want more detailed heuristics before deciding some action,
they can use batch_pending and batch_active as counts.

Non process context related statistics are only available
if CAP_SYS_ADMIN is hold.

Whole series can be found in:
https://github.com/mkuoppal/linux/commits/arb-robustness

Test case for i-g-t is in:
https://github.com/mkuoppal/intel-gpu-tools/commits/arb-robustness

Thanks for your feedback,
-Mika
