[PATCH 00/11] drm/xe: initial changes for XE OA

[Ashutosh Dixit]

This patchset is the initial port of i915 perf/OA functionality to the Xe
driver. It has been tested against the following IGT patch:

https://patchwork.freedesktop.org/series/121082/

The following features in i915 have not been ported and will be added (as
new patches) if/as they are needed:
* Inline batch submission on stream exec_queue/hw_engine
* NOA wait
* GuC ctx id (guc_sw_ctx_id)
* CTX_R_PWR_CLK_STATE/GEN8_R_PWR_CLK_STATE
* hold_preemption (DRM_XE_OA_PROP_HOLD_PREEMPTION)
* sseu_config (DRM_XE_OA_PROP_GLOBAL_SSEU)
* Override gucrc (override_gucrc_mode)
* MTL bios_c6_setup
* ratelimits
* compat ioctl

This series contains an additional HAX patch to help review these
patches. The additional HAX patch contains:
a. Incomplete ports of the features listed above which are not included in
   this patchset
b. FIXME highlighting significant changes between i915 and xe, and
c. FIXME containing author comments about implementation caveats

Therefore FIXME's (and associated comments) in the HAX patch should guide
in reviewing this Xe OA patchset.
