[Intel-gfx] [PATCH 0/2] drm/i915/perf: Add support for loadable OA configs

[Lionel Landwerlin]

Hi,

This series adds support for loadable OA configurations. It is based
off Matthew's initial work. This idea is to let userspace mostly hold
these configurations, so they can be tweaked from userspace without
patching the kernel, which is quite useful for debug purposes.

I've made sent IGT tests for it :

   https://patchwork.freedesktop.org/series/27010/

Though this series depends on a bunch of commits not fully reviewed
yet. You can find the branch here :

   https://github.com/djdeath/intel-gpu-tools/tree/wip/djdeath/oa-next

I've also tested this with GPUTop :

https://github.com/rib/gputop/commits/for-master

Eventually I'll produce the patches for Mesa and we'll be able to
remove most of the config from kernel space. I think it's best to
leave the test configs which are quite useful to verify stuff works as
expected, but if people feel they should go too, I'm okay with that.

Cheers,
