[ Upstream commit ac84ca815a ]
In some cases, e.g. during resuming from suspend, there is a possibility
that some IPC reply messages get received by the host while the DSP
firmware has not yet reached the complete boot state.
Detect when this happens and do not attempt to process the unexpected
replies from DSP. Instead, provide proper debugging support.

[ Upstream commit 91b98d5a6e ]
Stress testing resume from suspend on Valve Steam Deck OLED (Galileo)
revealed that the DSP firmware could enter an unrecoverable faulty
state, where the kernel ring buffer is flooded with IPC related error
messages:

A system reboot would be necessary to restore the speakers
functionality.
However, by delaying a bit any host to DSP transmission right after
the firmware boot completed, the issue could not be reproduced anymore
and sound continued to work flawlessly even after performing thousands
of suspend/resume cycles.
Introduce the post_fw_run_delay ACP quirk to allow providing the
aforementioned delay via the snd_sof_dsp_ops->post_fw_run() callback for
the affected devices.

Current rsnd driver supports Synchronous SRC Mode, but HW allow to update
rate only within 1% from current rate. Adjust to it.
Becially, this feature is used to fine-tune subtle difference that occur
during sampling rate conversion in SRC. So, it should be called within 1%
margin of rate difference.
If there was difference over 1%, it will apply with 1% increments by using
loop without indicating error message.

[ Upstream commit c3fc002b20 ]
rsnd_kctrl_accept_runtime() (1) is used for runtime convert rate
(= Synchronous SRC Mode). Now, rsnd driver has 2 kctrls for it
(A): "SRC Out Rate Switch"
(B): "SRC Out Rate" // it calls (1)
(A): can be called anytime
(B): can be called only runtime, and will indicate warning if it was used
at non-runtime.
To use runtime convert rate (= Synchronous SRC Mode), user might uses
command in below order.
(X): > amixer set "SRC Out Rate" on
> aplay xxx.wav &
(Y): > amixer set "SRC Out Rate" 48010 // convert rate to 48010Hz
(Y): calls B
(X): calls both A and B.
In this case, when user calls (X), it calls both (A) and (B), but it is not
yet start running. So, (B) will indicate warning.
This warning was added by commit b5c0886898 ("ASoC: rsnd: add warning
message to rsnd_kctrl_accept_runtime()"), but the message sounds like the
operation was not correct. Let's update warning message.
The message is very SRC specific, implement it in src.c

In some environments, the SCLP firmware interface used to query a
CHPID's configured state is not supported. On these environments,
rapidly reading the corresponding sysfs attribute produces inconsistent
results:
$ cat /sys/devices/css0/chp0.00/configure
cat: /sys/devices/css0/chp0.00/configure: Operation not supported
$ cat /sys/devices/css0/chp0.00/configure
3
This occurs for example when Linux is run as a KVM guest. The
inconsistency is a result of CIO using cached results for generating
the value of the "configure" attribute while failing to handle the
situation where no data was returned by SCLP.
Fix this by not updating the cache-expiration timestamp when SCLP
returns no data. With the fix applied, the system response is
consistent:
$ cat /sys/devices/css0/chp0.00/configure
cat: /sys/devices/css0/chp0.00/configure: Operation not supported
$ cat /sys/devices/css0/chp0.00/configure

The Omoton KB066 is an Apple A1255 keyboard clone (HID product code
05ac:022c). On both keyboards, the F6 key becomes Num Lock when the Fn
key is held. But unlike its Apple exemplar, when the Omoton's F6 key is
pressed without Fn, it sends the usage code 0xC0301 from the reserved
section of the consumer page instead of the standard F6 usage code
0x7003F from the keyboard page. The nonstandard code is translated to
KEY_UNKNOWN and becomes useless on Linux. The Omoton KB066 is a pretty
popular keyboard, judging from its 29,058 reviews on Amazon at time of
writing, so let's account for its quirk to make it more usable.
By the way, it would be nice if we could automatically set fnmode to 0
for Omoton keyboards because they handle the Fn key internally and the
kernel's Fn key handling creates undesirable side effects such as making
F1 and F2 always Brightness Up and Brightness Down in fnmode=1 (the
default) or always F1 and F2 in fnmode=2. Unfortunately I don't think
there's a way to identify Bluetooth keyboards more specifically than the
HID product code which is obviously inaccurate. Users of Omoton
keyboards will just have to set fnmode to 0 manually to get full Fn key
functionality.

startup and then every 20 seconds. If a firmware reset occurs right
after a clock sync, the driver would wait 20 seconds before performing
another clock sync with the firmware. This is particularly problematic
with the introduction of the "load firmware from host" feature, where
the driver performs a clock sync with the bootloader and then has to
wait 20 seconds before syncing with the main firmware.
This patch clears prev_sync immediately upon receiving an IPC reset,
so that the main firmware and driver will perform a clock sync
immediately after completing the IPC handshake.

[ Upstream commit 4b54ae6919 ]
The timestamps in the Firmware log and HID sensor samples are incorrect.
They show 1970-01-01 because the current IPC driver only uses the first
8 bytes of bootup time when synchronizing time with the firmware. The
firmware converts the bootup time to UTC time, which results in the
display of 1970-01-01.
In write_ipc_from_queue(), when sending the MNG_SYNC_FW_CLOCK message,
the clock is updated according to the definition of ipc_time_update_msg.
However, in _ish_sync_fw_clock(), the message length is specified as the
size of uint64_t when building the doorbell. As a result, the firmware
only receives the first 8 bytes of struct ipc_time_update_msg.
This patch corrects the length in the doorbell to ensure the entire
ipc_time_update_msg is sent, fixing the timestamp issue.

[ Upstream commit e9fe182772 ]
dsp_local_on has several incorrect assumptions, one of which is that
p->nr_cpus_allowed always tracks p->cpus_ptr. This is not true when a task
is scheduled out while migration is disabled - p->cpus_ptr is temporarily
overridden to the previous CPU while p->nr_cpus_allowed remains unchanged.
This led to sporadic test faliures when dsp_local_on_dispatch() tries to put
a migration disabled task to a different CPU. Fix it by keeping the previous
CPU when migration is disabled.
There are SCX schedulers that make use of p->nr_cpus_allowed. They should
also implement explicit handling for p->migration_disabled.

STATMOUNT_MNT_OPTS can actually be missing if there are no options. This
is a change of behavior since 75ead69a71 ("fs: don't let statmount return
empty strings").
The other checks shouldn't actually trigger, but add them for correctness
and for easier debugging if the test fails.

Building with GCC 15 results in build error

24 | static const unsigned char VBSF_MOUNT_SIGNATURE[4] = "\000\377\376\375";

cc1: all warnings being treated as errors
Due to GCC having enabled -Werror=unterminated-string-initialization[0]
by default. Separately initializing each array element of
VBSF_MOUNT_SIGNATURE to ensure NUL termination, thus satisfying GCC 15
and fixing the build error.

In [2] it was pointed out that parts of setarch weren't working
properly on alpha because it has it's own SET_PERSONALITY
implementation. In the discussion that followed Richard Henderson
pointed out that the 32bit pointer support for alpha was never
completed.
Fix this by removing alpha's 32bit pointer support.
As a bit of paranoia refuse to execute any alpha binaries that have
the EF_ALPHA_32BIT flag set. Just in case someone somewhere has
binaries that try to use alpha's 32bit pointer support.

namespace from a DFS interlink target, the server will return
STATUS_BAD_NETWORK_NAME and the following will appear on dmesg:
CIFS: VFS: BAD_NETWORK_NAME: \\dom\dfs
Since a DFS share might contain several DFS interlinks and they expire
after 10 minutes, the above message might end up being flooded on
dmesg when mounting or accessing them.
Print this only once per share.
