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.

9f19662550 iris: remove iris_monitor_config
perf_cfg is enough - it already contains almost all necessary
information and is constructed in a more optimal way (O(n) vs O(n^2)
- it uses hash table to build the unique counter list).

"Almost all", because it doesn't contain OA raw counters, but
we should have not exposed them anyway. Quoting Mark Janes:
"I see no reason to include the OA raw counters in the list that
are provided to the user. They are unusable.
The MDAPI library can be used to configure raw counters in a way
that provides esoteric metrics, but that library is written against
INTEL_performance_query."

A few hash_table users roll their own integer hash functions which
call _mesa_hash_data to perform the hashing which ultimately calls
into XXH32 with a dynamic key length. When using small keys with a
constant size the hash rate can be greatly improved by inlining
XXH32 and providing it a constant key length, see:
https://fastcompression.blogspot.com/2018/03/xxhash-for-small-keys-impressive-power.html

Additionally, this patch removes calls to _mesa_key_hash_string and
makes them instead call _mesa_has_string directly, matching the new
integer hash functions.

bd888bc1d6 i965/iris: perf-queries: don't invalidate/flush 3d pipeline
Our current implementation of performance queries is fairly harsh
because it completely flushes and invalidates the 3d pipeline caches
at the beginning and end of each query. An argument can be made that
this is how performance should be measured but it probably doesn't
reflect what the application is actually doing and the actual cost of
draw calls.

A more appropriate approach is to just stall the pipeline at
scoreboard, so that we measure the effect of a draw call without
having the pipeline in a completely pristine state for every draw
call.

v2: Use end of pipe PIPE_CONTROL instruction for Iris (Ken)

a575b3cd5c intel/perf: drop batchbuffer flushing at query begin
This was initially intended to fix issues with the query timings going
occassionally high.

It turns out there was a bug in the attribution of OA reports to our
context when parsing the OA data. This led to reports flagged with
other context IDs to be included in our queries results.

ddacd3d43b intel/perf: fix improper pointer access
This expression was unused by the macro, probably why it didn't
register in the compilation.

8c0b058263 intel/perf: simplify the processing of OA reports
This is a more accurate description of what happens in processing the
OA reports.

Previously we only had a somewhat difficult to parse state machine
tracking the context ID.

What we really only need to do to decide if the delta between 2
reports (r0 & r1) should be accumulated in the query result is :

   * whether the r0 is tagged with the context ID relevant to us

   * if r0 is not tagged with our context ID and r1 is: does r0 have a
     invalid context id? If not then we're in a case where i915 has
     resubmitted the same context for execution through the execlist
     submission port

v2: Update comment (Ken)

b364e920bf intel/perf: take into account that reports read can be fairly old
If we read the OA reports late enough after the query happens, we can
get a timestamp in the report that is significantly in the past
compared to the start timestamp of the query. The current code must
deal with the wraparound of the timestamp value (every ~6 minute). So
consider that if the difference is greater than half that wraparound
period, we're probably dealing with an old report and make the caller
aware it should read more reports when they're available.
