[Intel-xe] [PATCH 00/21] Add OA functionality to Xe

[Ashutosh Dixit]

This patchset is the initial port of i915 perf/OA functionality to the XE
driver. 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)
* 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:

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

The series has been tested against this IGT series:
        https://gitlab.freedesktop.org/adixit/igt-gpu-tools/-/tree/xe-oa

v2: Fix build
v3: Rebase, due to s/xe_engine/xe_exec_queue/
v4: Re-run for testing
v5: Address review comments, new patches 11 through 17
v6: New patches 18 through 21
