This came in as a code fix and not a bug report, so I don't think it

Commit 2a9127fcf229 ("mm: rewrite wait_on_page_bit_common() logic") made
the page locking entirely fair, in that if a waiter came in while the
lock was held, the lock would be transferred to the lockers strictly in
order.
That was intended to finally get rid of the long-reported watchdog
failures that involved the page lock under extreme load, where a process
could end up waiting essentially forever, as other page lockers stole
the lock from under it.
It also improved some benchmarks, but it ended up causing huge
performance regressions on others, simply because fair lock behavior
doesn't end up giving out the lock as aggressively, causing better
worst-case latency, but potentially much worse average latencies and
throughput.
Instead of reverting that change entirely, this introduces a controlled
amount of unfairness, with a sysctl knob to tune it if somebody needs
to. But the default value should hopefully be good for any normal load,
allowing a few rounds of lock stealing, but enforcing the strict
ordering before the lock has been stolen too many times.
There is also a hint from Matthieu Baerts that the fair page coloring
may end up exposing an ABBA deadlock that is hidden by the usual
optimistic lock stealing, and while the unfairness doesn't fix the
fundamental issue (and I'm still looking at that), it avoids it in
practice.
The amount of unfairness can be modified by writing a new value to the
'sysctl_page_lock_unfairness' variable (default value of 5, exposed
through /proc/sys/vm/page_lock_unfairness), but that is hopefully
something we'd use mainly for debugging rather than being necessary for
any deep system tuning.
This whole issue has exposed just how critical the page lock can be, and
how contended it gets under certain locks. And the main contention
doesn't really seem to be anything related to IO (which was the origin
of this lock), but for things like just verifying that the page file
mapping is stable while faulting in the page into a page table.

[Why]
DTM topology updates happens by default now. This results in DTM
warnings when hdcp is not even being enabled. This spams the dmesg
and doesn't effect normal display functionality so it is better to log it
using DRM_DEBUG_KMS()
[How]
Change the DRM_WARN() to DRM_DEBUG_KMS()

On A20R machines the interrupt pending bits in cause register need to be
updated by requesting the chipset to do it. This needs to be done to
find the interrupt cause and after interrupt service. In
commit 0b888c7f3a03 ("MIPS: SNI: Convert to new irq_chip functions") the
function to do after service update got lost, which caused spurious
interrupts.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

- Set PERF_SAMPLE_PERIOD if attr->freq is set.
- Remove trailing commas from AMD JSON vendor event files.
- Don't clear event's period if set by a event definition term.
- Leader sampling shouldn't clear sample period in 'perf test'.
- Fix the "signal" test inline assembly when built with DEBUG=1.
- Fix memory leaks detected by ASAN, some in normal paths, some in
error paths.
- Fix 2 memory sanitizer warnings in 'perf bench'.
- Fix the ratio comments of miss-events in 'perf stat'.
- Prevent override of attr->sample_period for libpfm4 events.
- Sync kvm.h and in.h headers with the kernel sources.

'perf stat' displays miss ratio of L1-dcache, L1-icache, dTLB cache,
iTLB cache and LL-cache. Take L1-dcache for example, miss ratio is
caculated as "L1-dcache-load-misses/L1-dcache-loads". So "of all
L1-dcache hits" is unsuitable to describe it, and "of all L1-dcache
accesses" seems better.
The comments of L1-icache, dTLB cache, iTLB cache and LL-cache are
fixed in the same way.

(NOTE: This is the minimal backportable fix, a full fix is being
developed at https://patchwork.freedesktop.org/patch/388048/)
The flags passed to the wait_entry.func are passed onwards to
try_to_wake_up(), which has a very particular interpretation for its
wake_flags. In particular, beyond the published WF_SYNC, it has a few
internal flags as well. Since we passed the fence->error down the chain
via the flags argument, these ended up in the default_wake_function
confusing the kernel/sched.

To implement preempt-to-busy (and so efficient timeslicing and best utilization
of the hardware submission ports) we let the GPU run asynchronously in respect
to the ELSP submission queue. This created challenges in keeping and accessing
the driver state mirroring the asynchronous GPU execution.
The latest occurence of this was spotted by KCSAN:

To complicate matters, we have to both avoid the read tearing of *active and
avoid any write tearing as perform the pending[] -> inflight[] promotion of the
execlists.
This is because we cannot rely on the memcpy doing u64 aligned copies on all
kernels/platforms and so we opt to open-code it with explicit WRITE_ONCE
annotations to satisfy KCSAN.

As we now protect the timeline list using RCU, we can drop the
timeline->mutex for guarding the list iteration during context close, as
we are searching for an inflight request. Any new request will see the
context is banned and not be submitted. In doing so, pull the checks for
a concurrent submission of the request (notably the
i915_request_completed()) under the engine spinlock, to fully serialise
with __i915_request_submit()). That is in the case of preempt-to-busy
where the request may be completed during the __i915_request_submit(),
we need to be careful that we sample the request status after
serialising so that we don't miss the request the engine is actually
submitting.

atomic_remove_fb disables the CRTC as needed for disabling the primary

This prevents at least the following problems if the primary plane gets
disabled (e.g. due to destroying the FB assigned to the primary plane,
as happens e.g. with mutter in Wayland mode):
* The legacy cursor ioctl returned EINVAL for a non-0 cursor FB ID
(which enables the cursor plane).
* If the cursor plane was enabled, changing the legacy DPMS property
value from off to on returned EINVAL.

* Minor changes to code comment and commit log, per review feedback.

It's dangerous to free the original metric when it's called from
resolve_metric() as it's already in the metric_list and might have other
resources too. Instead, it'd better let them bail out and be released
properly at the later stage.
So add a check when it's called from metricgroup__add_metric() and
release it. Also make sure that mp is set properly.

The evsel->unit borrows a pointer of pmu event or alias instead of
owns a string. But tool event (duration_time) passes a result of
strdup() caused a leak.
It was found by ASAN during metric test:

Asan reported leak of cpu and thread maps as they have one more refcount
than released. I found that after setting evlist maps it should release
it's refcount.
It seems to be broken from the beginning so I chose the original commit
as the culprit. But not sure how it's applied to stable trees since
there are many changes in the code after that.

I found some memory leaks while reading the metric code. Some are real
and others only occur in the error path. When it failed during metric
or event parsing, it should release all resources properly.

The amdzen2/core.json and amdzen/core.json vendor events files have the

lets remove it.
