[PATCH 0/1] Xe OA Consolidated Diffs

[Ashutosh Dixit]

Because Xe OA changes between successive revisions are distributed across
multiple patches, I am providing a combined diff of all changes in a single
patch to help with the code review.

These changes pertain to: https://patchwork.freedesktop.org/series/121084/

[PATCH 1/1] drm/xe/oa: Combined diff of changes between v10 and v11

[Ashutosh Dixit]

Because Xe OA changes between successive revisions are distributed across
multiple patches, provide a combined diff of all changes in a single patch
to help with the code review.

These changes pertain to: https://patchwork.freedesktop.org/series/121084/

This patch will not compile, it's purpose is to just provide the diff.

The diff between v10 and v11 consists of the following uapi changes:
* Use a chain of drm_xe_ext_set_property struct's also for stream
  reconfiguration (using DRM_XE_PERF_IOCTL_CONFIG perf fd ioctl). This
  will enable additional properties such as syncobj's during stream
  reconfiguration.
* Add extensions also to output structs from the kernel so they can also be
  extended if needed in the future
* Change DRM_XE_PERF ioctl number to 0x0b

Just wanted to propose a few minor tweaks to the Perf/OA uapi with this
patch. I have sent the new series with these changes here:

https://patchwork.freedesktop.org/series/121084/#rev11

But didn't copy you on the series itself (just this combined diff) so as
not to spam you. I have also retained your previous R-b's on the patches.

So please just take a look at this combined diff and let me know if there's
anything here you don't agree with or want done differently.

Thanks.
