There are error messages like below that are occurring during stress
testing: "[ 31.004009] xe 0000:03:00.0: [drm] ERROR GT0: Global
invalidation timeout". Previously it was hitting this 3 out of 1000
executions of warm reboot. After raising it to 500, 1000 warm reboot
executions passed and it didn't fail.
Due to the way xe_mmio_wait32() is implemented, the timeout is able to
expire early when the register matches the expected value due to the
wait increments starting small. So, the larger timeout value should have
no effect during normal use cases.
v2 (Jonathan):
- rework the commit message
v3 (Lucas):
- add conclusive message for the fail rate and test case
v4:
- add suggested-by

In the ad7124_write_raw() function, parameter val can potentially
be zero. This may lead to a division by zero when DIV_ROUND_CLOSEST()
is called within ad7124_set_channel_odr(). The ad7124_write_raw()
function is invoked through the sequence: iio_write_channel_raw() ->
iio_write_channel_attribute() -> iio_channel_write(), with no checks
in place to ensure val is non-zero.

In the ad9832_write_frequency() function, clk_get_rate() might return 0.
This can lead to a division by zero when calling ad9832_calc_freqreg().
The check if (fout > (clk_get_rate(st->mclk) / 2)) does not protect
against the case when fout is 0. The ad9832_write_frequency() function
is called from ad9832_write(), and fout is derived from a text buffer,
which can contain any value.

The raw value conversion to obtain a measurement in lux as
INT_PLUS_MICRO does not calculate the decimal part properly to display
it as micro (in this case microlux). It only calculates the module to
obtain the decimal part from a resolution that is 10000 times the
provided in the datasheet (0.5376 lux/cnt for the veml6030). The
resulting value must still be multiplied by 100 to make it micro.
This bug was introduced with the original implementation of the driver.
Only the illuminance channel is fixed becuase the scale is non sensical
for the intensity channels anyway.

Hou Tao says:
====================
Add the missing BPF_LINK_TYPE invocation for sockmap
From: Hou Tao <houtao1@huawei.com>
Hi,
The tiny patch set fixes the out-of-bound read problem when reading the
fdinfo of sock map link fd. And in order to spot such omission early for
the newly-added link type in the future, it also checks the validity of
the link->type and adds a WARN_ONCE() for missed invocation.
Please see individual patches for more details. And comments are always
welcome.
v3:
* patch #2: check and warn the validity of link->type instead of
adding a static assertion for bpf_link_type_strs array.

Clang 19 prints a warning when we pass &th->guid to efi_pa_va_lookup():
drivers/acpi/prmt.c:156:29: error: passing 1-byte aligned argument to
4-byte aligned parameter 1 of 'efi_pa_va_lookup' may result in an
unaligned pointer access [-Werror,-Walign-mismatch]
156 | (void *)efi_pa_va_lookup(&th->guid, handler_info->handler_address);
| ^
The problem is that efi_pa_va_lookup() takes a efi_guid_t and &th->guid
is a regular guid_t. The difference between the two types is the
alignment. efi_guid_t is a typedef.
typedef guid_t efi_guid_t __aligned(__alignof__(u32));
It's possible that this a bug in Clang 19. Even though the alignment of
&th->guid is not explicitly specified, it will still end up being aligned
at 4 or 8 bytes.
Anyway, as Ard points out, it's cleaner to change guid to efi_guid_t type
and that also makes the warning go away.

CS42L84 is a headphone jack codec made by Cirrus Logic and seen in Apple
computer models starting with 2021 Macbook Pros. It is not a publicly
documented part. To a degree the part is similar to the public CS42L42.
(The L84 superseded L83 seen in earlier Apple models, and the L83 was
pretty much the same as L42.)

Some jacks integrated on devices with this codec, such as certain
Apple Silicon Macs, have quite trigger-happy tip sense switches that
cause a tip sense IRQ before the plug is fully seated. If users are
unfortunate with their timing, this can lead to headsets being detected
as mic-less headphones among other issues with the codec's device
detection routines.
Introduce some rudimentary ring sense interrupt handling so that we
can re-trigger the codec's detection routines when we are certain
that the plug is fully seated.
This seems to differ from what other Cirrus drivers do, but is
necessary for devices to be reliably detected properly here.

The CS42L84 is a codec from Cirrus Logic found in Apple Silicon Macs.
The chip continues Apple's long tradition of compelling vendors to
spin out bespoke SKUs that are based on existing IP but made subtly
incompatible with the publicly available part. CS42L84 is very similar
to CS42L42, but has a different regmap.

The H616 has an audio codec compatible with the sun4i-a10 driver.
The codec is relatively cut down compared to some of the other Allwinner
SoCs and only has a single line-out route (relying on a separate digital
microphone IP block for input). HDMI and SPDIF audio are handled
separately by an audio hub IP block, which is not currently implemented
in mainline kernels. This requires some additional flexibility in the
DMA bindings.
Add compatible string and routing for the H616 audio codec, and update
the required DMA descriptions.

Some devices only have the playback side of the codec implemented
so add a quirk to check for this. This flag is only required internally

p9_get_mapped_pages() uses iov_iter_get_pages_alloc2() to extract pages
from an iterator when performing a zero-copy request and under some
circumstances, this crashes with odd page errors[1], for example, I see:
page: refcount:0 mapcount:0 mapping:0000000000000000 index:0x0 pfn:0xbcf0
flags: 0x2000000000000000(zone=1)
...
page dumped because: VM_BUG_ON_FOLIO(((unsigned int) folio_ref_count(folio) + 127u <= 127u))
------------[ cut here ]------------
kernel BUG at include/linux/mm.h:1444!
This is because, unlike in iov_iter_extract_folioq_pages(), the
iter_folioq_get_pages() helper function doesn't skip the current folio
when iov_offset points to the end of it, but rather extracts the next
page beyond the end of the folio and adds it to the list. Reading will
then clobber the contents of this page, leading to system corruption,
and if the page is not in use, put_page() may try to clean up the unused
page.
This can be worked around by copying the iterator before each
extraction[2] and using iov_iter_advance() on the original as the
advance function steps over the page we're at the end of.
Fix this by skipping the page extraction if we're at the end of the
folio.
This was reproduced in the ktest environment[3] by forcing 9p to use the
fscache caching mode and then reading a file through 9p.

When rename moves an AFS subdirectory between parent directories, the
subdir also needs a bit of editing: the ".." entry needs updating to point
to the new parent (though I don't make use of the info) and the DV needs
incrementing by 1 to reflect the change of content. The server also sends
a callback break notification on the subdirectory if we have one, but we
can take care of recovering the promise next time we access the subdir.
This can be triggered by something like:
mount -t afs %example.com:xfstest.test20 /xfstest.test/
mkdir /xfstest.test/{aaa,bbb,aaa/ccc}
touch /xfstest.test/bbb/ccc/d
mv /xfstest.test/{aaa/ccc,bbb/ccc}
touch /xfstest.test/bbb/ccc/e
When the pathwalk for the second touch hits "ccc", kafs spots that the DV
is incorrect and downloads it again (so the fix is not critical).
Fix this, if the rename target is a directory and the old and new
parents are different, by:
(1) Incrementing the DV number of the target locally.
(2) Editing the ".." entry in the target to refer to its new parent's
vnode ID and uniquifier.

====================
net: dsa: mv88e6xxx: fix MV88E6393X PHC frequency on internal clock
The MV88E6393X family of switches can additionally run their cycle
counters using a 250MHz internal clock instead of the usual 125MHz
external clock [1].
The driver currently assumes all designs utilize that external clock,
but MikroTik's RB5009 uses the internal source - causing the PHC to be
seen running at 2x real time in userspace, making synchronization
with ptp4l impossible.
This series adds support for reading off the cycle counter frequency
known to the hardware in the TAI_CLOCK_PERIOD register and picking an
appropriate set of scaling coefficients instead of using a fixed set
for each switch family.
Patch 1 groups those cycle counter coefficients into a new structure to
make it easier to pass them around.
Patch 2 modifies PTP initialization to probe TAI_CLOCK_PERIOD and
use an appropriate set of coefficients.
Patch 3 adds support for 4000ps cycle counter periods.
Changes since v2 [2]:
- Patch 1: "net: dsa: mv88e6xxx: group cycle counter coefficients"
- Moved declaration of mv88e6xxx_cc_coeffs to avoid moving that in
Patch 2.
- Patch 2: "net: dsa: mv88e6xxx: read cycle counter period from hardware"
- Removed move of mv88e6xxx_cc_coeffs declaration.
- Patch 3: "net: dsa: mv88e6xxx: support 4000ps cycle counter periods"
- No change.

The MV88E6393X family of devices can run its cycle counter off
an internal 250MHz clock instead of an external 125MHz one.
Add support for this cycle counter period by adding another set
of coefficients and lowering the periodic cycle counter read interval
to compensate for faster overflows at the increased frequency.
Otherwise, the PHC runs at 2x real time in userspace and cannot be
synchronized.

The existing code moves VF to the same namespace as the synthetic NIC
during netvsc_register_vf(). But, if the synthetic device is moved to a
new namespace after the VF registration, the VF won't be moved together.
To make the behavior more consistent, add a namespace check for synthetic
NIC's NETDEV_REGISTER event (generated during its move), and move the VF
if it is not in the same namespace.

The well-known errata regarding EEE not being functional on various KSZ
switches has been refactored a few times. Recently the refactoring has
excluded several switches that the errata should also apply to.
Disable EEE for additional switches with this errata and provide
additional comments referring to the public errata document.
The original workaround for the errata was applied with a register
write to manually disable the EEE feature in MMD 7:60 which was being
applied for KSZ9477/KSZ9897/KSZ9567 switch ID's.
Then came commit 26dd2974c5b5 ("net: phy: micrel: Move KSZ9477 errata
fixes to PHY driver") and commit 6068e6d7ba50 ("net: dsa: microchip:
remove KSZ9477 PHY errata handling") which moved the errata from the
switch driver to the PHY driver but only for PHY_ID_KSZ9477 (PHY ID)
however that PHY code was dead code because an entry was never added
for PHY_ID_KSZ9477 via MODULE_DEVICE_TABLE.
This was apparently realized much later and commit 54a4e5c16382 ("net:
phy: micrel: add Microchip KSZ 9477 to the device table") added the
PHY_ID_KSZ9477 to the PHY driver but as the errata was only being
applied to PHY_ID_KSZ9477 it's not completely clear what switches
that relates to.
Later commit 6149db4997f5 ("net: phy: micrel: fix KSZ9477 PHY issues
after suspend/resume") breaks this again for all but KSZ9897 by only
applying the errata for that PHY ID.
Following that this was affected with commit 08c6d8bae48c("net: phy:
Provide Module 4 KSZ9477 errata (DS80000754C)") which removes
the blatant register write to MMD 7:60 and replaces it by
setting phydev->eee_broken_modes = -1 so that the generic phy-c45 code
disables EEE but this is only done for the KSZ9477_CHIP_ID (Switch ID).
Lastly commit 0411f73c13af ("net: dsa: microchip: disable EEE for
KSZ8567/KSZ9567/KSZ9896/KSZ9897.") adds some additional switches
that were missing to the errata due to the previous changes.
This commit adds an additional set of switches.

When ata_qc_complete() schedules a command for EH using
ata_qc_schedule_eh(), blk_abort_request() will be called, which leads to
req->q->mq_ops->timeout() / scsi_timeout() being called.
scsi_timeout(), if the LLDD has no abort handler (libata has no abort
handler), will set host byte to DID_TIME_OUT, and then call
scsi_eh_scmd_add() to add the command to EH.
Thus, when commands first enter libata's EH strategy_handler, all the
commands that have been added to EH will have DID_TIME_OUT set.
Commit e5dd410acb34 ("ata: libata: Clear DID_TIME_OUT for ATA PT commands
with sense data") clears this bogus DID_TIME_OUT flag for all commands
that reached libata's EH strategy_handler.
libata has its own flag (AC_ERR_TIMEOUT), that it sets for commands that
have not received a completion at the time of entering EH.
ata_eh_worth_retry() has no special handling for AC_ERR_TIMEOUT, so by
default timed out commands will get flag ATA_QCFLAG_RETRY set, and will be
retried after the port has been reset (ata_eh_link_autopsy() always
triggers a port reset if any command has AC_ERR_TIMEOUT set).
For a command that has ATA_QCFLAG_RETRY set, while also having an error
flag set (e.g. AC_ERR_TIMEOUT), ata_eh_finish() will not increment
scmd->allowed, so the command will at most be retried scmd->allowed number
of times (which by default is set to 3).
However, scsi_eh_flush_done_q() will only retry commands for which
scsi_noretry_cmd() returns false.
For a command that has DID_TIME_OUT set, while also having either the
FAILFAST flag set, or the command being a passthrough command,
scsi_noretry_cmd() will return true. Thus, such a command will never be
retried.
Thus, make sure that libata sets SCSI's DID_TIME_OUT flag for commands that
actually timed out (libata's AC_ERR_TIMEOUT flag), such that timed out
commands will once again not be retried if they are also a FAILFAST or
passthrough command.

An uncomfortably large set of fixes due to me not getting round to

is mostly smaller driver specific changes, but there are a couple of
generic changes:
- Bumping the minimal topology ABI we check for during validation, the
code had support for v4 removed previously but the update of the
define used for initial validation was missed.
- Fix the assumption that DAPM structs will be embedded in a component
which isn't true for card widgets when doing name comparisons, though
fortunately this is rarely triggered.
We've pulled in one Soundwire fix which was part of a larger series
fixing cleanup issues in on Intel Soundwire systems.
