non BPF mode
The --for-each-cgroup can have the same cgroup multiple times, but this
confuses BPF counters (since they have the same cgroup id), making only
the last cgroup events to be counted.
Let's check the cgroup name before adding a new entry to the cgroups
list.
Before:
$ sudo ./perf stat -a --bpf-counters --for-each-cgroup /,/ sleep 1
Performance counter stats for 'system wide':
<not counted> msec cpu-clock /
<not counted> context-switches /
<not counted> cpu-migrations /

3,385,168 branch-misses / # 5.87% of all branches
1.002220125 seconds time elapsed
After it becomes similar to the non-BPF mode:
$ sudo ./perf stat -a --bpf-counters --for-each-cgroup /,/ sleep 1
Performance counter stats for 'system wide':
8,013.38 msec cpu-clock / # 7.998 CPUs utilized

Committer notes:
As a reminder, to test with BPF counters one has to use BUILD_BPF_SKEL=1
in the make command line and have clang/llvm installed when building
perf, otherwise the --bpf-counters option will not be available:
# perf stat -a --bpf-counters --for-each-cgroup /,/ sleep 1
Error: unknown option `bpf-counters'
Usage: perf stat [<options>] [<command>]
-a, --all-cpus system-wide collection from all CPUs

When --for-each-cgroup option is used, it fails when any of events is
not supported and exits immediately. This is not how 'perf stat'
handles unsupported events.
Let's ignore the failure and proceed with others so that the output is
similar to when BPF counters are not used:
Before:
$ sudo ./perf stat -a --bpf-counters -e L1-icache-loads,L1-dcache-loads --for-each-cgroup system.slice,user.slice sleep 1
Failed to open first cgroup events
$
After it shows output similat to when --bpf-counters isn't specified:
$ sudo ./perf stat -a --bpf-counters -e L1-icache-loads,L1-dcache-loads --for-each-cgroup system.slice,user.slice sleep 1
Performance counter stats for 'system wide':
<not supported> L1-icache-loads system.slice
29,892,418 L1-dcache-loads system.slice
<not supported> L1-icache-loads user.slice

The busy timeout logic checks for the AUX BUSY, then waits for the
timeout period and then after timeout reads the register for BUSY or
Success.
Instead replace interrupt with polling so as to read the AUX CTL
register often before the timeout period. Looks like there might be some
issue with interrupt-on-read. Hence changing the logic to polling read.
v2: replace interrupt with polling read
v3: use usleep_rang instead of msleep, updated commit msg
v4: use intel_wait_for_regiter internal function
v5: use __intel_de_wait_for_register with 500us slow and 10ms fast timeout
v6: check return value of __intel_de_wait_for_register
v7: using default 2us for intel_de_wait_for_register

Both commits appeared in v6.2-rc1, so the latter missed the conversion from

Although we applied a workaround for the hw constraints code with the
implicit feedback sync, it still has a potential problem. Namely, as
the code treats only the first matching (sync) endpoint, it might be
too restrictive when multiple endpoints are listed in the substream's
format list.
This patch is another attempt to improve the hw constraint handling
for the implicit feedback sync. The code is rewritten and the sync EP
handling for the rate and the format is put inside the fmt_list loop
in each hw_rule_*() function instead of the additional rules. The
rules for the period size and periods are extended to loop over the
fmt_list like others, and they apply the constraints only if needed.

The fix commit the commit e4ea77f8e53f ("ALSA: usb-audio: Always apply
the hw constraints for implicit fb sync") tried to address the bug
where an incorrect PCM parameter is chosen when two (implicit fb)
streams are set up at the same time. This change had, however, some
side effect: once when the sync endpoint is chosen and set up, this
restriction is applied at the next hw params unless it's freed via hw
free explicitly.
This patch is a workaround for the problem by relaxing the hw
constraints a bit for the implicit fb sync. We still keep applying
the hw constraints for implicit fb sync, but only when the matching
sync EP is being used by other streams.

At the PCM hw params, we may re-configure the endpoints and it's done
by a temporary EP close followed by re-open. A potential problem
there is that the EP might be already running internally at the PCM
prepare stage; it's seen typically in the playback stream with the
implicit feedback sync. As this stream start isn't tracked by the
core PCM layer, we'd need to stop it explicitly, and that's the
missing piece.
This patch adds the stop_endpoints() call at snd_usb_hw_params() to
assure the stream stop before closing the EPs.

There are 3 possible interrupt sources are handled by DP controller,
HPDstatus, Controller state changes and Aux read/write transaction.
At every irq, DP controller have to check isr status of every interrupt
sources and service the interrupt if its isr status bits shows interrupts
are pending. There is potential race condition may happen at current aux
isr handler implementation since it is always complete dp_aux_cmd_fifo_tx()
even irq is not for aux read or write transaction. This may cause aux read
transaction return premature if host aux data read is in the middle of
waiting for sink to complete transferring data to host while irq happen.
This will cause host's receiving buffer contains unexpected data. This
patch fixes this problem by checking aux isr and return immediately at
aux isr handler if there are no any isr status bits set.
Current there is a bug report regrading eDP edid corruption happen during
system booting up. After lengthy debugging to found that VIDEO_READY
interrupt was continuously firing during system booting up which cause
dp_aux_isr() to complete dp_aux_cmd_fifo_tx() prematurely to retrieve data
from aux hardware buffer which is not yet contains complete data transfer
from sink. This cause edid corruption.
Follows are the signature at kernel logs when problem happen,
EDID has corrupt header

If memory has been found early_init_dt_scan_memory now returns 1. If
it hasn't found any memory it will return 0, allowing other memory
setup mechanisms to carry on.
Previously early_init_dt_scan_memory always returned 0 without

plat_mem_setup code wouldn't be executed anymore. Making
early_init_dt_scan_memory the only way to initialize the memory.

SwathSizePerSurfaceY[] and SwathSizePerSurfaceC[] values are uninitialized

[Why]
We skip dsc_validation on pipes that are underlays, but in the
acquire_dsc code we don't have this check.
In certain conditions (when underlay pipe index is lower) we will assign
the dsc resource to the underlay pipe and skip the base pipe.
Now during dsc_validation we will skip the underlay pipe (this has the
dsc resource) but try to validate the base pipe(this doesn't have a dsc
resource) due to this mismatch we hit a NULLPTR
[How]
In the acquire_dsc add a check for underlay pipe so we
don't acquire a dsc resource for this pipe. This will match the
acquire/validation conditions.

- Also update sequence for enabling / disabling phantom streams
(apply_ctx_to_hw). When enabling phantom pipes, enable before
doing front end programming for phantom pipes. If disabling
phantom pipes, disable after front end programming (i.e. after
phantom plane disable)
- TODO: Still need to properly handle transition case when a phantom
pipe is transitioned directly into a real pipe (need to fully disable
