To address this grep 3.8 warning:
grep: warning: stray \ before #
We needed to remove the '' around the grep expression and keep the \
before # so that it is escaped by the $(shell grep ...) and thus doesn't
get to grep.
We need that \ before the #, otherwise we get this:
Makefile.perf:364: *** unterminated call to function 'shell': missing ')'. Stop.
As everything after the # will be considered a comment.
Removing the single quotes needs some more escaping so that _some_ of
the escaped chars gets to grep, like the '\|' that becomes '\\\|´.

we get:

The hierarchy mode needs to setup output formats for each evsel.
Normally setup_sorting() handles this at the beginning, but it cannot
do that if data comes from a pipe since there's no evsel info before
reading the data. And then perf report cannot process the samples
in hierarchy mode and think as if there's no sample.
Let's check the condition and setup the output formats after reading
data so that it can find evsels.
Before:
$ ./perf record -o- true | ./perf report -i- --hierarchy -q
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.000 MB - ]
Error:
The - data has no samples!
After:
$ ./perf record -o- true | ./perf report -i- --hierarchy -q

Currently lock contention timestamp is maintained in a hash map keyed by
pid. That means it needs to get and release a map element (which is
proctected by spinlock!) on each contention begin and end pair. This
can impact on performance if there are a lot of contention (usually from
spinlocks).
It used to go with task local storage but it had an issue on memory
allocation in some critical paths. Although it's addressed in recent
kernels IIUC, the tool should support old kernels too. So it cannot
simply switch to the task local storage at least for now.
As spinlocks create lots of contention and they disabled preemption
during the spinning, it can use per-cpu array to keep the timestamp to
avoid overhead in hashmap update and delete.
In contention_begin, it's easy to check the lock types since it can see
the flags. But contention_end cannot see it. So let's try to per-cpu
array first (unconditionally) if it has an active element (lock != 0).
Then it should be used and per-task tstamp map should not be used until
the per-cpu array element is cleared which means nested spinlock
contention (if any) was finished and it nows see (the outer) lock.

When pelem is NULL, it'd create a new entry with zero data. But it
might be preempted by IRQ/NMI just before calling bpf_map_update_elem()
then there's a chance to call it twice for the same pid. So it'd be
better to use BPF_NOEXIST flag and check the return value to prevent
the race.

It checks the current lock to calculated the delta of contention time.
The address is saved in the tstamp map which is allocated at begining of
contention and released at end of contention.
But it's possible for bpf_map_delete_elem() to fail. In that case, the
element in the tstamp map kept for the current lock and it makes the
next contention for the same lock tracked incorrectly. Specificially
the next contention begin will see the existing element for the task and
it'd just return. Then the next contention end will see the element and
calculate the time using the timestamp for the previous begin.
This can result in a large value for two small contentions happened from
time to time. Let's clear the lock address so that it can be updated
next time even if the bpf_map_delete_elem() failed.

Drop delayed_work_cb() instead make hidpp_connect_event() the workqueue
function itself.

There is a connect event race in hidpp_probe() in these 2 lines:
connected = hidpp_root_get_protocol_version(hidpp) == 0;
atomic_set(&hidpp->connected, connected);
Specifically the following can happen:
1. This line from hidpp_probe() is executed:
connected = hidpp_root_get_protocol_version(hidpp) == 0;
and sets connected to false;
2. A connect-event packet is received and does:
atomic_set(&hidpp->connected, true);
3. The next line from hidpp_probe() is executed:
atomic_set(&hidpp->connected, connected);
and sets the atomic_t back to 0 again.
4. hidpp_connect_event() runs and sees the connected device
as disconnected because of this.
To fix this make hidpp_connect_event() query the connection status
of the device itself instead of having it rely on possibly stale
data cached in struct hidpp_device.

Move the hidpp_overwrite_name() call to before the connect check, this
puts it at the same place in the probe() order as hidpp_serial_init()
which seems more logical. This should not make a difference since this
is in the non-unifying path and only unifying devices can be probed
in non-connected state.
This is a preparation patch for moving all connected state handling
to hidpp_connect_event().
Doing this before the connect check requires dropping the protocol
version check since protocol_major is not set yet now. Instead
this relies on hidpp_root_get_feature(HIDPP_PAGE_GET_DEVICE_NAME_TYPE)
failing on older devices, just like how hidpp_get_serial() relies on
hidpp_root_get_feature(HIDPP_PAGE_DEVICE_INFORMATION) failing on older
devices. So this again makes the code more consistent.
Also stop printing an error on failure now, since with the proto
version check gone failures are expected to happen on older devices.

receiver, but not connected atm) hidpp_connect_event() takes care
of calling wtp_get_config() when the device later connects.
There is no need to have a separate code path for WTP devices which
are connected at probe() time, these can use the same code-path since
probe() will queue hidpp_connect_event() for those at probe time.
Drop the unnecessary wtp_get_config() call from probe().

hidpp_connect_event()
Calling get_wireless_feature_index() from probe() causes
the wireless_feature_index to only get set for unifying devices which
are already connected at probe() time. It does not get set for devices
which connect later.
Fix this by moving get_wireless_feature_index() to hidpp_connect_event(),
this does not make a difference for devices connected at probe() since
probe() will queue the hidpp_connect_event() for those at probe time.

Commit 91cf9a98ae41 ("HID: logitech-hidpp: make .probe usbhid capable")
makes hidpp_probe() first call hid_hw_start(hdev, 0) to allow IO
without connecting any hid subdrivers (hid-input, hidraw).
This is done to allow to retrieve the device's name and serial number
and store these in hdev->name and hdev->uniq.
Then later on IO was stopped and started again with hid_hw_start(hdev,
HID_CONNECT_DEFAULT) connecting hid-input and hidraw after the name
and serial number have been setup.
Commit 498ba2069035 ("HID: logitech-hidpp: Don't restart communication
if not necessary") changed the probe() code to only do the start with
a 0 connect-mask + restart later for unifying devices.
But for non unifying devices hdev->name and hdev->uniq are updated too.
So this change re-introduces the problem for which the start with
a 0 connect-mask + restart later behavior was introduced.
The previous patch in this series changes the unifying path to instead of
restarting IO only call hid_connect() later. This avoids possible issues
with restarting IO seen on non unifying devices.
Revert the change to limit the restart behavior to unifying devices to
fix hdev->name changing after userspace facing devices have already been
registered.

Restarting IO causes 2 problems:
1. Some devices do not like IO being restarted this was addressed in
commit 498ba2069035 ("HID: logitech-hidpp: Don't restart communication
if not necessary"), but that change has issues of its own and needs to
be reverted.
2. Restarting IO and specifically calling hid_device_io_stop() causes
received packets to be missed, which may cause connect-events to
get missed.
Restarting IO was introduced in commit 91cf9a98ae41 ("HID: logitech-hidpp:
make .probe usbhid capable") to allow to retrieve the device's name and
serial number and store these in hdev->name and hdev->uniq before
connecting any hid subdrivers (hid-input, hidraw) exporting this info
to userspace.
But this does not require restarting IO, this merely requires deferring
calling hid_connect(). Calling hid_hw_start() with a connect-mask of
0 makes it skip calling hid_connect(), so hidpp_probe() can simply call
hid_connect() later without needing to restart IO.
Remove the stop + restart of IO and instead just call hid_connect() later
to avoid the issues caused by restarting IO.
Now that IO is no longer stopped, hid_hw_close() must be called at the end
of probe() to balance the hid_hw_open() done at the beginning probe().

The USB Compact Keyboard variant requires a reset_resume function to
restore keyboard configuration after a suspend in some situations. Move
configuration normally done on probe to lenovo_features_set_cptkbd(), then
recycle this for use on reset_resume.
Without, the keyboard and driver would end up in an inconsistent state,
breaking middle-button scrolling amongst other problems, and twiddling
sysfs values wouldn't help as the middle-button mode won't be set until
the driver is reloaded.
Tested on a USB and Bluetooth Thinkpad Compact Keyboard.

Some sc7180 devices use audio adsp to play sound. The setup for this
adsp is similar to the dirrect lpass usage but requires the use of
different link ids and clocks.
This commit adds support for the qdsp based audio, reusing the common
parts like audio codec setup and jack creation.
Since the setup is mostly generic and codec specific setup is guarded
behind a check, a generic compatible is added, similar to other
platforms. Even though those changes target Acer Aspire 1 as the only
user of the adsp audio on this platform present upstream at the moment
of the commit, those changes should be either dirrectly compatible or
trivially expandable to the other devices that will be added in the
future.

Unlike all designs supported sofar the Lenovo Yoga Tab 3 YT3-X90 does not

different input maps and add support for both setups with the current

The new INTMIC_IN1L_HSMIC_IN2L map is enabled by default on CHT because
the Lenovo Yoga Tab 3 YT3-X90 model is the only Cherry Trail design
