[Intel-gfx] [RFC] [PATCH 0/7] arb robustness enablers

[Mika Kuoppala]

Hi,

This patchset adds ioctl and related changes to allow
userspace to query about the context loss status of the
specified context. The aim is to provide enabler
for the ARB_Robustness GL extension.

I post this as RFC to get ack/nack on the interface.
The interface is in 0004-drm-i915-add-i915_get_reset_status_ioctl.patch

Also any feedback on the other parts of the patchset is most
welcomed.

The i-g-t testcase can be found here:
https://github.com/mkuoppal/intel-gpu-tools/commits/arb-robustness

Thanks,
--Mika
