The Dell OptiPlex 7770 AIO needs the same quirk as the 7760 AIO. The
backlight can be controlled with the native controller, intel_backlight,
but not with dell_uart_backlight.
I dumped the DSDT using acpidump, acpixtract and iasl, and confirmed
that it contains the DELL0501 device. When loading the
dell_uart_backlight driver with `rmmod dell_uart_backlight`, `modprobe
dell_uart_backlight dyndbg`, it reports "Firmware version: GL_Re_V18".

After acpi_init_device_object(), the lifetime of struct acpi_device is
managed by the driver core through reference counting.
Both acpi_add_power_resource() and acpi_add_single_object() call
acpi_init_device_object() and then invoke acpi_device_add(). If that
fails, their error paths call the release callback directly instead of
dropping the device reference through acpi_dev_put().
This bypasses the normal device lifetime rules and frees the object
without releasing the reference acquired by device_initialize(), which
may lead to a refcount leak.
The issue was identified by a static analysis tool I developed and
confirmed by manual review.
Fix both error paths by using acpi_dev_put() and let the release
callback handle the final cleanup.

When big joiner is enabled, it reserves the adjacent pipe as the
secondary pipe. This happens without the user space knowing, and
subsequent attempts at using the CRTC with that pipe will fail. If the
user space does not have a coping mechanism, i.e. trying another CRTC,
this leads to a black screen.
Try to reduce the impact of the problem on discrete platforms by mapping
the CRTCs to pipes in order A, C, B, and D. If the user space reserves
CRTCs in order, this should trick it to using pipes that are more likely
to be available for and after joining.
Limit this to discrete platforms, which have four pipes, and no eDP, a
combination that should benefit the most with least drawbacks.

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Support HW queue leasing, allowing containers to be granted access
to HW queues for zero-copy operations and AF_XDP
- Number of code moves to help the compiler with inlining. Avoid
output arguments for returning drop reason where possible
- Rework drop handling within qdiscs to include more metadata about
the reason and dropping qdisc in the tracepoints
- Remove the rtnl_lock use from IP Multicast Routing
- Pack size information into the Rx Flow Steering table pointer
itself. This allows making the table itself a flat array of u32s,
thus making the table allocation size a power of two
- Report TCP delayed ack timer information via socket diag
- Add ip_local_port_step_width sysctl to allow distributing the
randomly selected ports more evenly throughout the allowed space
- Add support for per-route tunsrc in IPv6 segment routing
- Start work of switching sockopt handling to iov_iter
- Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
buffer size drifting up
- Support MSG_EOR in MPTCP
- Add stp_mode attribute to the bridge driver for STP mode selection.
This addresses concerns about call_usermodehelper() usage
- Remove UDP-Lite support (as announced in 2023)
- Remove support for building IPv6 as a module. Remove the now
unnecessary function calling indirection
Cross-tree stuff:
- Move Michael MIC code from generic crypto into wireless, it's
considered insecure but some WiFi networks still need it
Netfilter:
- Switch nft_fib_ipv6 module to no longer need temporary dst_entry
object allocations by using fib6_lookup() + RCU.
Florian W reports this gets us ~13% higher packet rate
- Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
switch the service tables to be per-net. Convert some code that
walks the service lists to use RCU instead of the service_mutex
- Add more opinionated input validation to lower security exposure
- Make IPVS hash tables to be per-netns and resizable
Wireless:
- Finished assoc frame encryption/EPPKE/802.1X-over-auth
- Radar detection improvements
- Add 6 GHz incumbent signal detection APIs
- Multi-link support for FILS, probe response templates and client
probing
- New APIs and mac80211 support for NAN (Neighbor Aware Networking,
aka Wi-Fi Aware) so less work must be in firmware
Driver API:
- Add numerical ID for devlink instances (to avoid having to create
fake bus/device pairs just to have an ID). Support shared devlink
instances which span multiple PFs
- Add standard counters for reporting pause storm events (implement
in mlx5 and fbnic)
- Add configuration API for completion writeback buffering (implement
in mana)
- Support driver-initiated change of RSS context sizes

- Welcome new BPF maintainers: Kumar Kartikeya Dwivedi, Eduard
Zingerman while Martin KaFai Lau reduced his load to Reviwer.
- Lots of fixes everywhere from many first time contributors. Thank you
All.
- Diff stat is dominated by mechanical split of verifier.c into
multiple components:
- backtrack.c: backtracking logic and jump history
- states.c: state equivalence
- cfg.c: control flow graph, postorder, strongly connected
components
- liveness.c: register and stack liveness
- fixups.c: post-verification passes: instruction patching, dead
code removal, bpf_loop inlining, finalize fastcall
8k line were moved. verifier.c still stands at 20k lines.
Further refactoring is planned for the next release.

Pull arm64 updates from Catalin Marinas:
"The biggest changes are MPAM enablement in drivers/resctrl and new PMU
support under drivers/perf.
On the core side, FEAT_LSUI lets futex atomic operations with EL0
permissions, avoiding PAN toggling.
The rest is mostly TLB invalidation refactoring, further generic entry
work, sysreg updates and a few fixes.
Core features:
- Add support for FEAT_LSUI, allowing futex atomic operations without
toggling Privileged Access Never (PAN)
- Further refactor the arm64 exception handling code towards the
generic entry infrastructure
- Optimise __READ_ONCE() with CONFIG_LTO=y and allow alias analysis
through it
Memory management:
- Refactor the arm64 TLB invalidation API and implementation for
better control over barrier placement and level-hinted invalidation
- Enable batched TLB flushes during memory hot-unplug
- Fix rodata=full block mapping support for realm guests (when
BBML2_NOABORT is available)
Perf and PMU:
- Add support for a whole bunch of system PMUs featured in NVIDIA's
Tegra410 SoC (cspmu extensions for the fabric and PCIe, new drivers
for CPU/C2C memory latency PMUs)
- Clean up iomem resource handling in the Arm CMN driver
- Fix signedness handling of AA64DFR0.{PMUVer,PerfMon}
MPAM (Memory Partitioning And Monitoring):
- Add architecture context-switch and hiding of the feature from KVM
- Add interface to allow MPAM to be exposed to user-space using
resctrl
- Add errata workaround for some existing platforms
- Add documentation for using MPAM and what shape of platforms can
use resctrl
Miscellaneous:
- Check DAIF (and PMR, where relevant) at task-switch time
- Skip TFSR_EL1 checks and barriers in synchronous MTE tag check mode
(only relevant to asynchronous or asymmetric tag check modes)
- Remove a duplicate allocation in the kexec code
- Remove redundant save/restore of SCS SP on entry to/from EL0

Add conditional bus regulator enable/disable in mtk_i2c_transfer()
to support I2C bus power gating for platforms that require it.
This implementation:
- Enables bus_regulator before clk_bulk_enable() if vbus-supply is defined
- Disables bus_regulator after clk_bulk_disable()
- Only activates when vbus-supply is provided in device tree
- Has no impact on platforms without vbus-supply defined
This approach provides power savings for platforms with an extra I2C bus
regulator, while avoiding runtime PM complexity.
Tested on MT8188.

Pull x86 SEV updates from Borislav Petkov:
- Change the SEV host code handling of when SNP gets enabled in order
to allow the machine to claim SNP-related resources only when SNP
guests are really going to be launched. The user requests this by
loading the ccp module and thus it controls when SNP initialization
is done
So export an API which module code can call and do the necessary SNP
setup only when really needed
- Drop an unnecessary write-back and invalidate operation that was
being performed too early, since the ccp driver already issues its
own at the correct point in the initialization sequence
- Drop the hotplug callbacks for enabling SNP on newly onlined CPUs,
which were both architecturally unsound (the firmware rejects
initialization if any CPU lacks the required configuration) and buggy
(the MFDM SYSCFG MSR bit was not being set)

Under some circumstances I2C recovery fails on Armada 3700. At least
on the Methode uDPU board, removing and replugging an SFP module fails
often, like this:
[ 36.953127] sfp sfp-eth1: module removed
[ 38.468549] i2c i2c-1: i2c_pxa: timeout waiting for bus free
[ 38.486960] sfp sfp-eth1: module MENTECHOPTO POS22-LDCC-KR rev 1.0 sn MNC208U90009 dc 200828
[ 38.496867] mvneta d0040000.ethernet eth1: unsupported SFP module: no common interface modes
[ 38.521448] hwmon hwmon2: temp1_input not attached to any thermal zone
[ 39.249196] sfp sfp-eth1: module removed
...
[ 292.568799] sfp sfp-eth1: please wait, module slow to respond
...
[ 625.208814] sfp sfp-eth1: failed to read EEPROM: -EREMOTEIO
Note that the 'unsupported SFP module' messages are not relevant. The
module is used only for testing the I2C recovery funcionality, because
the error can be triggered easily with this specific one.
Enabling debug in the i2c-pxa driver reveals the following:
[ 82.034678] sfp sfp-eth1: module removed
[ 90.008654] i2c i2c-1: slave_0x50 error: timeout with active message
[ 90.015112] i2c i2c-1: msg_num: 2 msg_idx: 0 msg_ptr: 0
[ 90.020464] i2c i2c-1: IBMR: 00000003 IDBR: 000000a0 ICR: 000007e0 ISR: 00000802
[ 90.027906] i2c i2c-1: log:
[ 90.030787]
This continues until the retries are exhausted ...
[ 110.192489] i2c i2c-1: slave_0x50 error: exhausted retries
[ 110.198012] i2c i2c-1: msg_num: 2 msg_idx: 0 msg_ptr: 0
[ 110.203323] i2c i2c-1: IBMR: 00000003 IDBR: 000000a0 ICR: 000007e0 ISR: 00000802
[ 110.210810] i2c i2c-1: log:
[ 110.213633]
... then the whole sequence starts again ...
[ 115.368641] i2c i2c-1: slave_0x50 error: timeout with active message
... while finally the SFP core gives up:
[ 671.975258] sfp sfp-eth1: failed to read EEPROM: -EREMOTEIO
When we analyze the log, it can be seen that bit 1 and 11 is set in the
ISR (Interface Status Register). Bit 1 indicates the ACK/NACK status, but
the purpose of bit 11 is not documented in the driver code unfortunately.
The 'Functional Specification' document of the Armada 3700 SoCs family
however says that this bit indicates an 'Early Bus Busy' condition. The
document also notes that whenever this bit is set, it is not possible to
initiate a transaction on the I2C bus. The observed behaviour corresponds
to this statement.
Unfortunately, I2C recovery does not help as it never runs in this
special case. Although the driver checks the busyness of the bus at
several places, but since it does not consider the A3700 specific bit
in these checks it can't determine the actual status of the bus correctly
which results in the errors above.
In order to fix the problem, add a new member to struct 'i2c_pxa' to
store a controller specific bitmask containing the bits indicating the
busy status, and use that in the code while checking the actual status
of the bus. This ensures that the correct status can be determined on
the Armada 3700 based devices without causing functional changes on
devices based on other SoCs.
With the change applied, the driver detects the busy condition, and runs
the recovery process:
[ 742.617312] i2c i2c-1: state:i2c_pxa_wait_bus_not_busy:449: ISR=00000802, ICR=000007e0, IBMR=03
[ 742.626099] i2c i2c-1: i2c_pxa: timeout waiting for bus free
[ 742.631933] i2c i2c-1: recovery: resetting controller, ISR=0x00000802
[ 742.638421] i2c i2c-1: recovery: IBMR 0x00000003 ISR 0x00000000
This clears the EBB bit in the ISR register, so it makes it possible to
initiate transactions on the I2C bus again.
After this patch, the SFP module used for testing can be removed and
replugged numerous times without causing the error described at the
beginning. Previously, the error happened after a few such attempts.
The patch has been tested also with the following kernel versions:
5.10.251, 5.15.201, 6.1.164, 6.6.127, 6.12.74, 6.14.11, 6.15.10, 6.16.1,
6.18.13, 6.19.3
It improves recovery on all of them.

pse_control_find_by_id(). Correct the function name in the documentation
to match the implementation.

pre_exit
wg_netns_pre_exit() manually acquires rtnl_lock() inside the
pernet .pre_exit callback. This causes a hung task when another
thread holds rtnl_mutex - the cleanup_net workqueue (or the
setup_net failure rollback path) blocks indefinitely in
wg_netns_pre_exit() waiting to acquire the lock.
Convert to .exit_rtnl, introduced in commit 7a60d91c690b ("net:
Add ->exit_rtnl() hook to struct pernet_operations."), where the
framework already holds RTNL and batches all callbacks under a
single rtnl_lock()/rtnl_unlock() pair, eliminating the contention
window.
The rcu_assign_pointer(wg->creating_net, NULL) is safe to move
from .pre_exit to .exit_rtnl (which runs after synchronize_rcu())
because all RCU readers of creating_net either use maybe_get_net()
- which returns NULL for a dying namespace with zero refcount - or
access net->user_ns which remains valid throughout the entire
ops_undo_list sequence.

Pull timer core updates from Thomas Gleixner:
- A rework of the hrtimer subsystem to reduce the overhead for
frequently armed timers, especially the hrtick scheduler timer:
- Better timer locality decision
- Simplification of the evaluation of the first expiry time by
keeping track of the neighbor timers in the RB-tree by providing
a RB-tree variant with neighbor links. That avoids walking the
RB-tree on removal to find the next expiry time, but even more
important allows to quickly evaluate whether a timer which is
rearmed changes the position in the RB-tree with the modified
expiry time or not. If not, the dequeue/enqueue sequence which
both can end up in rebalancing can be completely avoided.
- Deferred reprogramming of the underlying clock event device. This
optimizes for the situation where a hrtimer callback sets the
need resched bit. In that case the code attempts to defer the
re-programming of the clock event device up to the point where
the scheduler has picked the next task and has the next hrtick
timer armed. In case that there is no immediate reschedule or
soft interrupts have to be handled before reaching the reschedule
point in the interrupt entry code the clock event is reprogrammed
in one of those code paths to prevent that the timer becomes
stale.
- Support for clocksource coupled clockevents
The TSC deadline timer is coupled to the TSC. The next event is
programmed in TSC time. Currently this is done by converting the
CLOCK_MONOTONIC based expiry value into a relative timeout,
converting it into TSC ticks, reading the TSC adding the delta
ticks and writing the deadline MSR.
As the timekeeping core has the conversion factors for the TSC
already, the whole back and forth conversion can be completely
avoided. The timekeeping core calculates the reverse conversion
factors from nanoseconds to TSC ticks and utilizes the base
timestamps of TSC and CLOCK_MONOTONIC which are updated once per
tick. This allows a direct conversion into the TSC deadline value
without reading the time and as a bonus keeps the deadline
conversion in sync with the TSC conversion factors, which are
updated by adjtimex() on systems with NTP/PTP enabled.
- Allow inlining of the clocksource read and clockevent write
functions when they are tiny enough, e.g. on x86 RDTSC and WRMSR.
With all those enhancements in place a hrtick enabled scheduler
provides the same performance as without hrtick. But also other
hrtimer users obviously benefit from these optimizations.
- Robustness improvements and cleanups of historical sins in the
hrtimer and timekeeping code.
- Rewrite of the clocksource watchdog.
The clocksource watchdog code has over time reached the state of an
impenetrable maze of duct tape and staples. The original design,
which was made in the context of systems far smaller than today, is
based on the assumption that the to be monitored clocksource (TSC)
can be trivially compared against a known to be stable clocksource
(HPET/ACPI-PM timer).
Over the years this rather naive approach turned out to have major
flaws. Long delays between the watchdog invocations can cause wrap
arounds of the reference clocksource. The access to the reference
clocksource degrades on large multi-sockets systems dure to
interconnect congestion. This has been addressed with various
heuristics which degraded the accuracy of the watchdog to the point
that it fails to detect actual TSC problems on older hardware which
exposes slow inter CPU drifts due to firmware manipulating the TSC to
hide SMI time.
The rewrite addresses this by:
- Restricting the validation against the reference clocksource to
the boot CPU which is usually closest to the legacy block which
contains the reference clocksource (HPET/ACPI-PM).
- Do a round robin validation betwen the boot CPU and the other
CPUs based only on the TSC with an algorithm similar to the TSC
synchronization code during CPU hotplug.
- Being more leniant versus remote timeouts
- The usual tiny fixes, cleanups and enhancements all over the place

The HP OMEN MAX 16-ak0xxx (8D87) requires the same WMI queries as other
Victus S devices, hence it has been added to the corresponding list.
For this reason, platform_profile_victus_s_get_ec() will be called
during thermal_profile_setup() and victus_s_powersource_event() to
obtain hardware state (platform profile) by reading from the Embedded
Controller, however, this particular board's EC does not seem to expose
the platform profile value, unlike other boards. Hence EC readback is
disabled.
Testing on board 8D87 confirmed that platform profile is registered
successfully and fan RPMs are readable and controllable.
