Originally the type of path_ok is bool to denote that DPK is ready on

more than one calibration set, so use type u8 instead to record the

In most cases zcomp_available_show() is the only emitting
function that is called from sysfs read() handler, so it
assumes that there is a whole PAGE_SIZE buffer to work with.
There is an exception, however: recomp_algorithm_show().
In recomp_algorithm_show() we prepend the buffer with
priority number before we pass it to zcomp_available_show(),
so it cannot assume PAGE_SIZE anymore and must take
recomp_algorithm_show() modifications into consideration.
Therefore we need to pass buffer offset to zcomp_available_show().
Also convert it to use sysfs_emit_at(), to stay aligned
with the rest of zram's sysfs read() handlers.
On practice we are never even close to using the whole PAGE_SIZE
buffer, so that's not a critical bug, but still.

Replace scnprintf() with sysfs_emit() or sysfs_emit_at() in sysfs
*_show() functions in zram_drv.c to follow the kernel's guidelines
from Documentation/filesystems/sysfs.rst.
This improves consistency, safety, and makes the code easier to
maintain and update in the future.

The pll1_d8 clock is enabled by the boot loader, and is ultimately a
parent for numerous clocks, including those used by APB and AXI buses.
Guodong Xu discovered that this clock got disabled while responding to
getting -EPROBE_DEFER when requesting a reset controller.
The needed clock (CLK_DMA, along with its parents) had already been
enabled. To respond to the probe deferral return, the CLK_DMA clock
was disabled, and this led to parent clocks also reducing their enable
count. When the enable count for pll1_d8 was decremented it became 0,
which caused it to be disabled. This led to a system hang.
Marking that clock critical resolves this by preventing it from being
disabled.
Define a new macro CCU_FACTOR_GATE_DEFINE() to allow clock flags to
be supplied for a CCU_FACTOR_GATE clock.

Fixups
- Fixed raw pointer leakage and unsafe behavior in printk()
. Switch from %pK to %p for pointer formatting, as %p is now safer
and prevents issues like raw pointer leakage and acquiring sleeping
locks in atomic contexts.
- Fixed kernel panic during boot
. A NULL pointer dereference issue occasionally occurred
when the vblank interrupt handler was called before
the DRM driver was fully initialized during boot.
So this patch fixes the issue by adding a check in the interrupt handler
to ensure the DRM driver is properly initialized.
- Fixed a lockup issue on Samsung Peach-Pit/Pi Chromebooks
. The issue occurred after commit c9b1150a68d9 changed
the call order of CRTC enable/disable and bridge pre_enable/post_disable
methods, causing fimd_dp_clock_enable() to be called
before the FIMD device was activated. To fix this,
runtime PM guards were added to fimd_dp_clock_enable()
to ensure proper operation even when CRTC is not enabled.

soc-button-array hardcodes a debounce value by means of gpio_keys
which uses pinctrl-amd as a backend to program debounce for a GPIO.
This hardcoded value doesn't match what the firmware intended to be
programmed in _AEI. The hardcoded debounce leads to problems waking
from suspend. There isn't appetite to conditionalize the behavior in
soc-button-array or gpio-keys so clear it when the system suspends to
avoid problems with being able to resume.

This fixes a bunch of command hangs after runtime suspend/resume.
This fixes a regression caused by code movement in the commit below,
the commit seems to just change timings enough to cause this to happen
now, and adding the sleep seems to avoid it.
I've spent some time trying to root cause it to no great avail,
it seems like a bug on the firmware side, but it could be a bug
in our rpc handling that I can't find.
Either way, we should land the workaround to fix the problem,
while we continue to work out the root cause.

If CONFIG_DEBUG_FS is enabled, nouveau_drm_init() returns an error if it
fails to create the "nouveau" directory in debugfs. One case where that
will happen is when debugfs access is restricted by
CONFIG_DEBUG_FS_ALLOW_NONE or by the boot parameter debugfs=off, which
cause the debugfs APIs to return -EPERM.
So just ignore errors from debugfs. Note that nouveau_debugfs_root may
be an error now, but that is a standard pattern for debugfs. From
include/linux/debugfs.h:
"NOTE: it's expected that most callers should _ignore_ the errors
returned by this function. Other debugfs functions handle the fact that
the "dentry" passed to them could be an error and they don't crash in
that case. Drivers should generally work fine even if debugfs fails to
init anyway."

Add support for selecting multiple TLMM regions using the

The current implementation only selects the TLMM Node region
0, which can lead to incorrect region selection.
QCS 615 TLMM Node dts reg:
tlmm: pinctrl@3100000 {
compatible = "qcom,qcs615-tlmm";
reg = <0x0 0x03100000 0x0 0x300000>,

<0x0 0x03d00000 0x0 0x300000>;
reg-names = "east",
"west",
"south";
QCS615 gpio57 is in the south region with an offset of 0x39000,
and its address is 0x3d39000. However, the default region selection
is region 0 (east region), resulting in a wrong calculated address
of 0x3139000.
Add a tlmm option parameter named tlmm_reg_name to select the region.
If the user does not input the parameter, the default region is 0.

Seeing some unexplained random failures during LRC context switches with

Commit 3a1edef8f4b5 ("drm/xe: Make WA BB part of LRC BO") helped to
reduce the issues in the context switches, but didn't eliminate them
completely.
Indirect ring state is not required for any current features, so disable

There is a remote chance that after migration, some GTs will not
send the MIGRATED interrupt, or due to current VF KMD state the
interrupt will not lead to marking the GT for recovery.
Requiring IRQs from all GTs before starting migration introduces
the possibility that the process will get stalled due to one GuC.
One could argue it is also waste of time to wait for all IRQs,
but we should get them all IRQs as soon as VGPU starts, so that's
not really an impactful argument.
Still, not waiting for all GTs makes it easier to handle situations:
* where one GuC IRQ is missing
* where state before probe is unclean - getting MIGRATED IRQ as soon
as interrupts are enabled
* where multiple migrations happen close to each other
To help with these cases, this patch alters the post-migration
recovery so that recovery task is started as soon as one GuC IRQ
is handled, and other GTs are included in recovery later as the
subsequent IRQs are serviced.
The post-migration recovery can now be called for any selection of
GTs, and it will perform recovery on all GTs for which IRQs have
arrived, even multiple times if necessary.

recovery. Under this circumstance, the hardware restart fails and the
radio is rendered inoperational.

The default timeout set in mt76_connac2_mcu_fill_message of 20 seconds
leads to excessive stalling in case messages are lost.
Testing showed that a smaller timeout of 5 seconds is sufficient in
normal operation.

Increase the timeout for MCU_EXT_CMD_EFUSE_BUFFER_MODE command.
Regular retries upon hardware-recovery have been observed. Increasing
the timeout slightly remedies this problem.

Rather than returning ERR_PTR or NULL on failure, replace the NULL
return with ERR_PTR(-ENOMEM). This simplifies error handling at the
caller. While here, add kernel documentation for
drmm_alloc_ordered_workqueue.

Add `tx_timeout_count` to ethtool statistics to provide visibility into
transmit timeout events, bringing igbvf in line with other Intel
ethernet drivers.
Currently `tx_timeout_count` is incremented in igbvf_watchdog_task() and
igbvf_tx_timeout() but is not exposed to userspace nor used elsewhere in
the driver.
Before:
# ethtool -S ens5 | grep tx
tx_packets: 43
tx_bytes: 4408
tx_restart_queue: 0
After:
# ethtool -S ens5 | grep tx
tx_packets: 41
tx_bytes: 4241
tx_restart_queue: 0
tx_timeout_count: 0

Remove `int_counter0` and `int_counter1` from struct igbvf_adapter since
they are only incremented in interrupt handlers igbvf_intr_msix_rx() and
igbvf_msix_other(), but never read or used anywhere in the driver.
Note that igbvf_intr_msix_tx() does not have similar counter increments,
suggesting that these were likely overlooked during development.
Eliminate the fields and their unnecessary accesses in interrupt
handlers.

Add Tx Hang detection due to an unhandled MDD Event.
Previously, a malicious VF could disable the entire port causing
TX to hang on the E610 card.
Those events that caused PF to freeze were not detected
as an MDD event and usually required a Tx Hang watchdog timer
to catch the suspension, and perform a physical function reset.
Implement flows in the affected PF driver in such a way to check
the cause of the hang, detect it as an MDD event and log an
entry of the malicious VF that caused the Hang.
The PF blocks the malicious VF, if it continues to be the source
of several MDD events.

When an event is detected it is logged and, for the time being, the
queue is immediately re-enabled. This is due to the lack of an API
to the hypervisor so it could deal with it as it chooses.

Add malicious driver detection to ixgbe driver. The supported devices
are E610 and X550.
Handling MDD events is enabled while VFs are created and turned off
when they are disabled. There is no runtime command to enable or
disable MDD independently.
MDD event is logged when malicious VF driver is detected. For example VF
can try to send incorrect Tx descriptor (TSO on, but length field not
correct). It can be reproduced by manipulating the driver, or using
driver with incorrect descriptor values.
Example log:
"Malicious event on VF 0 tx:128 rx:128"

New timestamping API was introduced in commit 66f7223039c0 ("net: add
NDOs for configuring hardware timestamping") from kernel v6.6.
It is time to convert the Intel i40e driver to the new API, so that
timestamping configuration can be removed from the ndo_eth_ioctl() path
completely.
