3c51325025 intel/perf: switch query code to use query layout
That way we can describe new registers to that could be used both by
Anv & Iris/i965 without having to modifying code in multiple places.

v2: Do reverse order for begin queries so that we have MI_RPC as close
    as possible from the drawcall

8750f43a90 intel/perf: add performance query layout using MI_SRM
For all generations supported we had a layout describing what register
to store to implement a MI_RPC replacement.

This is because, on Gen12 we need to snapshot OAG registers to get
correct values for the perf equations. There, the MI_RPC instruction
captures OAR register which do not have all the information we need.

v2: Fix commented code for debug (Marcin)

a6e980e9bf intel/perf: prep work to enable new perf counters
Those are not part of the OA reports and need some additional
scaffolding. Those counters are only available when doing queries as
we need to emit MI_SRMs to record them.

Equations making use of those counters are not there yet, they will
come in a follow up commit updating a bunch of oa-*.xml files.

v2: Fix typo

v3: Use PERF_CNT_VALUE_MASK (Marcin)

9a54aa131e intel/perf: move gt_frequency to results
We want to unify things a bit between GL & Vulkan. So store those
values in the results rather than just in the GL query code.

ec1fa1d51f intel/perf: fix raw query kernel metric selection
The raw query is meant to be used with MDAPI [1]. When using this
metric without this library, we usually selected the TestOa metric to
provide some default sensible values (instead of undefined).
Historically this TestOa metric lived in the kernel at ID=1. We
removed all metrics from the kernel in kernel commit 9aba9c188da136
("drm/i915/perf: remove generated code").

This fixes the Mesa code to use a valid metric set ID (1 could work
some of the time, but not guaranteed).

[1] : https://github.com/intel/metrics-discovery

v2: Store fallback metric at init time

v3: Drop TestOa lookout

v4: Skip the existing queries (Marcin)

2fbab5a1b3 intel/perf: fix performance counters availability after glFinish
Currently Linux kernel gathers performance counters at fixed
intervals (~5-10ms), so if application uses AMD_performance_monitor
extension and immediately after glFinish() asks GL driver for HW
performance counter values it might not get any data (values == 0).

Fix this by moving the "read counters from kernel" code from
"is query ready" to "get counter values" callback with a loop around
it. Unfortunately it means that the "read counters from kernel"
code can spin for up to 10ms.

Ideally kernel should gather performance counters whenever we ask
it for counter values, but for now we have deal with what we have.
