[Intel-xe] [PATCH v2 00/10] Add OA functionality to Xe

[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:

* 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

I am providing the following additional HAX patch (not part of this series)
to help review these patches:

https://patchwork.freedesktop.org/patch/548718/?series=120100&rev=3

The commit message in the above patch explains how it can be useful for
reviewing this series.
