caf4daae87 ice: improve debug print for control queue messages
The ice_debug_cq function is called to print debug data for a control queue
descriptor in multiple places. This includes both before we send a message
on a transmit queue, after the writeback completion of a message on the
transmit queue, and when we receive a message on a receive queue.

This function does not include data about *which* control queue the message
is on, nor whether it was what we sent to the queue or what we received
from the queue.

Modify ice_debug_cq to take two extra parameters, a pointer to the control
queue and a boolean indicating if this was a response or a command. Improve
the debug messages by replacing "CQ CMD" with a string indicating which
specific control queue (based on cq->qtype) and whether this was a command
sent by the PF or a response from the queue.

This helps make the log output easier to understand and consume when
debugging.

Simon Horman says:

====================
net: header and core spelling corrections

This patchset addresses a number of spelling errors in comments in
Networking files under include/, and files in net/core/. Spelling
problems are as flagged by codespell.

It aims to provide patches that can be accepted directly into net-next.
And splits patches up based on maintainer boundaries: many things
feed directly into net-next. This is a complex process and I apologise
for any errors.

I also plan to address, via separate patches, spelling errors in other
files in the same directories, for files whose changes typically go
through trees other than net-next (which feed into net-next).

5f6df173f9 ice: implement and use rd32_poll_timeout for ice_sq_done timeout
The ice_sq_done function is used to check the control queue head register
and determine whether or not the control queue processing is done. This
function is called in a loop checking against jiffies for a specified
timeout.

The pattern of reading a register in a loop until a condition is true or a
timeout is reached is a relatively common pattern. In fact, the kernel
provides a read_poll_timeout function implementing this behavior in
<linux/iopoll.h>

Use of read_poll_timeout is preferred over directly coding these loops.
However, using it in the ice driver is a bit more difficult because of the
rd32 wrapper. Implement a rd32_poll_timeout wrapper based on
read_poll_timeout.

Refactor ice_sq_done to use rd32_poll_timeout, replacing the loop calling
ice_sq_done in ice_sq_send_cmd. This simplifies the logic down to a single
ice_sq_done() call.

The implementation of rd32_poll_timeout uses microseconds for its timeout
value, so update the CQ timeout macros used to be specified in microseconds
units as well instead of using HZ for jiffies.

f85cd6aec1 Merge branch 'add-alcd-support-to-cable-testing-interface'
Oleksij Rempel says:

====================
Add ALCD Support to Cable Testing Interface

This patch series introduces support for Active Link Cable Diagnostics
(ALCD) in the ethtool cable testing interface and the DP83TD510 PHY
driver.

Why ALCD?
On a 10BaseT1L interface, TDR (Time Domain Reflectometry) is not
possible if the link partner is active - TDR will fail in these cases
because it requires interrupting the link. Since the link is active, we
already know the cable is functioning, so instead of using TDR, we can
use ALCD.

ALCD lets us measure cable length without disrupting the active link,
which is crucial in environments where network uptime is important. It
provides a way to gather diagnostic data without the need for downtime.

What's in this series:
- Extended the ethtool cable testing interface to specify the source of
  diagnostic results (TDR or ALCD).
- Updated the DP83TD510 PHY driver to use ALCD when the link is
  active, ensuring we can still get cable length info without dropping the
  connection.

986a7fa4b4 phy: dp83td510: Utilize ALCD for cable length measurement when link is active
In industrial environments where 10BaseT1L PHYs are replacing existing
field bus systems like CAN, it's often essential to retain the existing
cable infrastructure. After installation, collecting metrics such as
cable length is crucial for assessing the quality of the infrastructure.
Traditionally, TDR (Time Domain Reflectometry) is used for this purpose.
However, TDR requires interrupting the link, and if the link partner
remains active, the TDR measurement will fail.

Unlike multi-pair systems, where TDR can be attempted during the MDI-X
switching window, 10BaseT1L systems face greater challenges. The TDR
sequence on 10BaseT1L is longer and coincides with uninterrupted
autonegotiation pulses, making TDR impossible when the link partner is
active.

The DP83TD510 PHY provides an alternative through ALCD (Active Link
Cable Diagnostics), which allows for cable length measurement without
disrupting an active link. Since a live link indicates no short or open
cable states, ALCD can be used effectively to gather cable length
information.

Enhance the dp83td510 driver by:
- Leveraging ALCD to measure cable length when the link is active.
- Bypassing TDR when a link is detected, as ALCD provides the required
  information without disruption.

4715d87e11 ethtool: Add support for specifying information source in cable test results

This is particularly useful for PHYs that offer multiple diagnostic
methods, such as Time Domain Reflectometry (TDR) and Active Link Cable
Diagnostic (ALCD).

Key changes:
- Added `ethnl_cable_test_result_with_src` and
  `ethnl_cable_test_fault_length_with_src` functions to allow specifying
  the information source when reporting cable test results.
- Updated existing `ethnl_cable_test_result` and
  `ethnl_cable_test_fault_length` functions to use TDR as the default
  source, ensuring backward compatibility.
- Modified the UAPI to support these new attributes, enabling drivers to
  provide more detailed diagnostic information.

For example, some TI 10BaseT1L PHYs provide two variants of cable

drivers to indicate whether the result was derived from TDR or ALCD,
improving the clarity and utility of diagnostic information.

09d77be560 arm64: dts: qcom: Add support for X1-based Surface Laptop 7 devices
Add support for Surface Laptop 7 machines, based on X1E80100.

The feature status is mostly on par with other X Elite machines,
notably lacking:

- USB-A and probably USB-over-Surface-connector (pending NXP retimer
  support)
- SD card reader (Realtek RTS5261 connected over PCIe)
- Touchscreen and touchpad support (hid-over-SPI [1])
- Audio (a quick look suggests the setup is very close to the one in
  X1E CRD)

The two Surface Laptop 7 SKUs (13.8" and 15") only have very minor
differences, amounting close to none on the software side. Even the
MBN firmware files and ACPI tables are shared between the two machines.

With that in mind, support is added for both, although only the larger
one was physically tested. Display differences will be taken care of
through fused-in EDID and other matters should be solved within the
EC and boot firmware.

====================
netconsole: Populate dynamic entry even if netpoll fails

The current implementation of netconsole removes the entry and fails
entirely if netpoll fails to initialize. This approach is suboptimal, as
it prevents reconfiguration or re-enabling of the target through
configfs.

While this issue might seem minor if it were rare, it actually occurs
frequently when the network module is configured as a loadable module.

In such cases, the network is unavailable when netconsole initializes,
causing netpoll to fail. This failure forces users to reconfigure the
target from scratch, discarding any settings provided via the command
line.

The proposed change would keep the target available in configfs, albeit
in a disabled state. This modification allows users to adjust settings
or simply re-enable the target once the network module has loaded,
providing a more flexible and user-friendly solution.

908ee298c8 net: netconsole: Populate dynamic entry even if netpoll fails
Currently, netconsole discards targets that fail during initialization,
causing two issues:

1) Inconsistency between target list and configfs entries
  * user pass cmdline0, cmdline1. If cmdline0 fails, then cmdline1
    becomes cmdline0 in configfs.

2) Inability to manage failed targets from userspace
  * If user pass a target that fails with netpoll (interface not loaded at
    netcons initialization time, such as interface is a module), then
    the target will not exist in the configfs, so, user cannot re-enable
    or modify it from userspace.

Failed targets are now added to the target list and configfs, but
remain disabled until manually enabled or reconfigured. This change does

ae5a0456e0 netpoll: Ensure clean state on setup failures
Modify netpoll_setup() and __netpoll_setup() to ensure that the netpoll
structure (np) is left in a clean state if setup fails for any reason.
This prevents carrying over misconfigured fields in case of partial
setup success.

Key changes:
- np->dev is now set only after successful setup, ensuring it's always
  NULL if netpoll is not configured or if netpoll_setup() fails.
- np->local_ip is zeroed if netpoll setup doesn't complete successfully.
- Added DEBUG_NET_WARN_ON_ONCE() checks to catch unexpected states.
- Reordered some operations in __netpoll_setup() for better logical flow.

These changes improve the reliability of netpoll configuration, since it
assures that the structure is fully initialized or totally unset.

ff555fc553 remoteproc: imx_rproc: Add support for poweroff and reboot
On some NXP platforms (e.g i.MX7ULP) the poweroff and reboot operations
are done via a separate remote core.

Typically Linux needs to send a message to the remote core and requests
for poweroff or reboot.

By default the communication between Linux core and the remote core is
is done via a blocking mailbox mechanism but Linux doesn't allow blocking
operations in the system off (reboot, power off) handlers.

So, we need to make sure the mailbox message send operations do not block
for this specific operations. Fortunately, Linux allows us to register
handlers that are called in preparation of the system off operations.

Thus, before carrying the power off or reboot preparations, just destroy
the existing mailboxes and create them as non-blocking.

Note that power off and restart are totally different operations and are
not complementary.

We introduce a new flag in the imx remoteproc per device data which tells
us when a device needs this special setup. For now, only imx7ulp needs it.

d9dbd7149c remoteproc: imx_rproc: Allow setting of the mailbox transmit mode
Current mailbox is blocking by default, but there are cases where we don't
need to wait for a response.

Linux just needs to send data to the remote processor, so let's
allow tx_block mode to be set (true/false) depending on usecase.

No functional changes.

3a84454f52 wifi: iwlwifi: mvm: don't wait for tx queues if firmware is dead
There is a WARNING in iwl_trans_wait_tx_queues_empty() (that was
recently converted from just a message), that can be hit if we
wait for TX queues to become empty after firmware died. Clearly,
we can't expect anything from the firmware after it's declared dead.

Don't call iwl_trans_wait_tx_queues_empty() in this case. While it could
be a good idea to stop the flow earlier, the flush functions do some
maintenance work that is not related to the firmware, so keep that part
of the code running even when the firmware is not running.
