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:

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)

Merge tag 'modules-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux
Pull module updates from Sami Tolvanen:
"Kernel symbol flags:
- Replace the separate *_gpl symbol sections (__ksymtab_gpl and
__kcrctab_gpl) with a unified symbol table and a new __kflagstab
section.
This section stores symbol flags, such as the GPL-only flag, as an
8-bit bitset for each exported symbol. This is a cleanup that
simplifies symbol lookup in the module loader by avoiding table
fragmentation and will allow a cleaner way to add more flags later
if needed.
Module signature UAPI:
- Move struct module_signature to the UAPI headers to allow reuse by
tools outside the kernel proper, such as kmod and
scripts/sign-file.
This also renames a few constants for clarity and drops unused
signature types as preparation for hash-based module integrity
checking work that's in progress.
Sysfs:
- Add a /sys/module/<module>/import_ns sysfs attribute to show the
symbol namespaces imported by loaded modules.
This makes it easier to verify driver API access at runtime on
systems that care about such things (e.g. Android).
Cleanups and fixes:
- Force sh_addr to 0 for all sections in module.lds. This prevents
non-zero section addresses when linking modules with 'ld.bfd -r',
which confused elfutils.
- Fix a memory leak of charp module parameters on module unload when
the kernel is configured with CONFIG_SYSFS=n.
- Override the -EEXIST error code returned by module_init() to
userspace. This prevents confusion with the errno reserved by the
module loader to indicate that a module is already loaded.
- Simplify the warning message and drop the stack dump on positive
returns from module_init().
- Drop unnecessary extern keywords from function declarations and
synchronize parse_args() arguments with their implementation"

Merge tag 'timers-core-2026-04-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
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

Merge tag 'gpio-updates-for-v7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"For this merge window we have two new drivers: support for
GPIO-signalled ACPI events on Intel platforms and a generic
GPIO-over-pinctrl driver using the ARM SCMI protocol for
controlling pins.
Several things have been reworked in GPIO core: we unduplicated GPIO
hog handling, reduced the number of SRCU locks and dereferences,
improved support for software-node-based lookup and removed more
legacy code after converting remaining users to modern alternatives.
There's also a number of driver reworks and refactoring, documentation
updates, some bug-fixes and new tests.
GPIO core:
- defer probe on software node lookups when the remote software node
exists but has not been registered as a firmware node yet
- unify GPIO hog handling by moving code duplicated in OF and ACPI
modules into GPIO core and allow setting up hogs with software
nodes
- allow matching GPIO controllers by secondary firmware node if
matching by primary does not succeed
- demote deferral warnings to debug level as they are quite normal
when using software nodes which don't support fw_devlink yet
- disable the legacy GPIO character device uAPI v1 supprt in Kconfig
by default
- rework several core functions in preparation for the upcoming
Revocable helper library for protecting resources against sudden
removal, this reduces the number of SRCU dereferences in GPIO core
- simplify file descriptor logic in GPIO character device code by
using FD_PREPARE()
- introduce a header defining symbols used by both GPIO consumers and
providers to avoid having to include provider-specific headers from
drivers which only consume GPIOs
- replace snprintf() with strscpy() where formatting is not required
New drivers:
- add the gpio-by-pinctrl generic driver using the ARM SCMI protocol
to control GPIOs (along with SCMI changes pulled from the pinctrl
tree)
- add a driver providing support for handling of platform events via
GPIO-signalled ACPI events (used on Intel Nova Lake and later
platforms)
Driver changes:
- extend the gpio-kempld driver with support for more recent models,
interrupts and setting/getting multiple values at once
- improve interrupt handling in gpio-brcmstb
- add support for multi-SoC systems in gpio-tegra186
- make sure we return correct values from the .get() callbacks in
several GPIO drivers by normalizing any values other than 0, 1 or
negative error numbers
- use flexible arrays in several drivers to reduce the number of
required memory allocations
- simplify synchronous waiting for virtual drivers to probe and
remove the dedicated, a bit overengineered helper library
dev-sync-probe
- remove unneeded Kconfig dependencies on OF_GPIO in several drivers
and subsystems
- convert the two remaining users of of_get_named_gpio() to using
GPIO descriptors and remove the (no longer used) function along
with the header that declares it
- add missing includes in gpio-mmio
- shrink and simplify code in gpio-max732x by using guard(mutex)
- remove duplicated code handling the 'ngpios' property from
gpio-ts4800, it's already handled in GPIO core
- use correct variable type in gpio-aspeed
- add support for a new model in gpio-realtek-otto
- allow to specify the active-low setting of simulated hogs over the
configfs interface (in addition to existing devicetree support) in
gpio-sim
Bug fixes:
- clear the OF_POPULATED flag on hog nodes in GPIO chip remove path
on OF systems
- fix resource leaks in error path in gpiochip_add_data_with_key()
- drop redundant device reference in gpio-mpsse
Tests:
- add selftests for use-after-free cases in GPIO character device
code
DT bindings:
- add a DT binding document for SCMI based, gpio-over-pinctrl devices
- fix interrupt description in microchip,mpfs-gpio
- add new compatible for gpio-realtek-otto
- describe the resets of the mpfs-gpio controller
- fix maintainer's email in gpio-delay bindings
- remove the binding document for cavium,thunder-8890 as the
corresponding device is bound over PCI and not firmware nodes
Documentation:
- update the recommended way of converting legacy boards to using
software nodes for GPIO description
- describe GPIO line value semantics
- misc updates to kerneldocs
Misc:
- convert OMAP1 ams-delta board to using GPIO hogs described with
software nodes"

Pull power management updates from Rafael Wysocki:
"Once again, cpufreq is the most active development area, mostly
because of the new feature additions and documentation updates in the
amd-pstate driver, but there are also changes in the cpufreq core
related to boost support and other assorted updates elsewhere.
Next up are power capping changes due to the major cleanup of the
Intel RAPL driver.
On the cpuidle front, a new C-states table for Intel Panther Lake is
added to the intel_idle driver, the stopped tick handling in the menu
and teo governors is updated, and there are a couple of cleanups.
Apart from the above, support for Tegra114 is added to devfreq and
there are assorted cleanups of that code, there are also two updates

- Fix sysfs files being present when HW missing and broken/outdated
documentation in the amd-pstate driver (Ninad Naik, Gautham Shenoy)
- Pass the policy to cpufreq_driver->adjust_perf() to avoid using

which leads to a scheduling-while-atomic bug (K Prateek Nayak)
- Clean up dead code in Kconfig for cpufreq (Julian Braha)
- Remove max_freq_req update for pre-existing cpufreq policy and add
a boost_freq_req QoS request to save the boost constraint instead

Pull ACPI support updates from Rafael Wysocki:
"These include an update of the CMOS RTC driver and the related ACPI
and x86 code that, among other things, switches it over to using the
platform device interface for device binding on x86 instead of the PNP
device driver interface (which allows the code in question to be
simplified quite a bit), a major update of the ACPI Time and Alarm
Device (TAD) driver adding an RTC class device interface to it, and
updates of core ACPI drivers that remove some unnecessary and not
really useful code from them.
Apart from that, two drivers are converted to using the platform
driver interface for device binding instead of the ACPI driver one,
which is slated for removal, support for the Performance Limited
register is added to the ACPI CPPC library and there are some
janitorial updates of it and the related cpufreq CPPC driver, the ACPI
processor driver is fixed and cleaned up, and NVIDIA vendor CPER
record handler is added to the APEI GHES code.
Also, the interface for obtaining a CPU UID from ACPI is consolidated
across architectures and used for fixing a problem with the PCI TPH
Steering Tag on ARM64, there are two updates related to ACPICA, a
minor ACPI OS Services Layer (OSL) update, and a few assorted updates
related to ACPI tables parsing.

- Replace strncpy() with strscpy_pad() in acpi_ut_safe_strncpy()
(Kees Cook)
- Trigger an ordered system power off after encountering a fatal

- Replace strlcat() in the ACPI processor idle drive with a better
alternative (Andy Shevchenko)
- Rearrange and clean up acpi_processor_errata_piix4() (Rafael
Wysocki)
- Move reference performance to capabilities and fix an uninitialized
variable in the ACPI CPPC library (Pengjie Zhang)
- Add support for the Performance Limited Register to the ACPI CPPC
library (Sumit Gupta)
- Add cppc_get_perf() API to read performance controls, extend
cppc_set_epp_perf() for FFH/SystemMemory, and make the ACPI CPPC
library warn on missing mandatory DESIRED_PERF register (Sumit
Gupta)
- Modify the cpufreq CPPC driver to update MIN_PERF/MAX_PERF in
target callbacks to allow it to control performance bounds via
standard scaling_min_freq and scaling_max_freq sysfs attributes and
add sysfs documentation for the Performance Limited Register to it
(Sumit Gupta)
- Add ACPI support to the platform device interface in the CMOS RTC
driver, make the ACPI core device enumeration code create a
platform device for the CMOS RTC, and drop CMOS RTC PNP device
support (Rafael Wysocki)
- Consolidate the x86-specific CMOS RTC handling with the ACPI TAD
driver and clean up the CMOS RTC ACPI address space handler (Rafael
Wysocki)
- Enable ACPI alarm in the CMOS RTC driver if advertised in ACPI FADT
and allow that driver to work without a dedicated IRQ if the ACPI
alarm is used (Rafael Wysocki)
- Clean up the ACPI TAD driver in various ways and add an RTC class
device interface, including both the RTC setting/reading and alarm
timer support, to it (Rafael Wysocki)
- Clean up the ACPI AC and ACPI PAD (processor aggregator device)
drivers (Rafael Wysocki)
- Rework checking for duplicate video bus devices and consolidate
pnp.bus_id workarounds handling in the ACPI video bus driver
(Rafael Wysocki)
- Update the ACPI core device drivers to stop setting
acpi_device_name() unnecessarily (Rafael Wysocki)
- Rearrange code using acpi_device_class() in the ACPI core device
drivers and update them to stop setting acpi_device_class()
unnecessarily (Rafael Wysocki)
- Define ACPI_AC_CLASS in one place (Rafael Wysocki)
- Convert the ni903x_wdt watchdog driver and the xen ACPI PAD driver
to bind to platform devices instead of ACPI devices (Rafael
Wysocki)
- Add devm_ghes_register_vendor_record_notifier(), use it in the PCI
hisi driver, and Add NVIDIA vendor CPER record handler (Kai-Heng
Feng)
- Consolidate the interface for obtaining a CPU UID from ACPI across
architectures and use it to address incorrect PCI TPH Steering Tag
on ARM64 resulting from the invalid assumption that the ACPI
Processor UID would always be the same as the corresponding logical
CPU ID in Linux (Chengwen Feng)"

Merge tag 'rust-7.1' of git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux
Pull Rust updates from Miguel Ojeda:
"Toolchain and infrastructure:
- Bump the minimum Rust version to 1.85.0 (and 'bindgen' to 0.71.1).
As proposed in LPC 2025 and the Maintainers Summit [1], we are
going to follow Debian Stable's Rust versions as our minimum
versions.
Debian Trixie was released on 2025-08-09 with a Rust 1.85.0 and
'bindgen' 0.71.1 toolchain, which is a fair amount of time for e.g.
kernel developers to upgrade.
Other major distributions support a Rust version that is high
enough as well, including:
+ Arch Linux.
+ Fedora Linux.
+ Gentoo Linux.
+ Nix.
+ openSUSE Slowroll and openSUSE Tumbleweed.
+ Ubuntu 25.10 and 26.04 LTS. In addition, 24.04 LTS using
their versioned packages.
The merged patch series comes with the associated cleanups and
simplifications treewide that can be performed thanks to both
bumps, as well as documentation updates.
In addition, start using 'bindgen''s '--with-attribute-custom-enum'
feature to set the 'cfi_encoding' attribute for the 'lru_status'
enum used in Binder.
Link: https://lwn.net/Articles/1050174/ [1]
- Add experimental Kconfig option ('CONFIG_RUST_INLINE_HELPERS') that
inlines C helpers into Rust.
Essentially, it performs a step similar to LTO, but just for the
helpers, i.e. very local and fast.
It relies on 'llvm-link' and its '--internalize' flag, and requires
a compatible LLVM between Clang and 'rustc' (i.e. same major
version, 'CONFIG_RUSTC_CLANG_LLVM_COMPATIBLE'). It is only enabled
for two architectures for now.
The result is a measurable speedup in different workloads that
different users have tested. For instance, for the null block
driver, it amounts to a 2%.
- Support global per-version flags.
While we already have per-version flags in many places, we didn't
have a place to set global ones that depend on the compiler
version, i.e. in 'rust_common_flags', which sometimes is needed to
e.g. tweak the lints set per version.
Use that to allow the 'clippy::precedence' lint for Rust < 1.86.0,
since it had a change in behavior.
- Support overriding the crate name and apply it to Rust Binder,
which wanted the module to be called 'rust_binder'.
- Add the remaining '__rust_helper' annotations (started in the
previous cycle).
'kernel' crate:
- Introduce the 'const_assert!' macro: a more powerful version of
'static_assert!' that can refer to generics inside functions or
implementation bodies, e.g.:
fn f<const N: usize>() {
const_assert!(N > 1);
}
fn g<T>() {
const_assert!(size_of::<T>() > 0, "T cannot be ZST");
}
In addition, reorganize our set of build-time assertion macros
('{build,const,static_assert}!') to live in the 'build_assert'
module.
Finally, improve the docs as well to clarify how these are
different from one another and how to pick the right one to use,
and their equivalence (if any) to the existing C ones for extra
clarity.
- 'sizes' module: add 'SizeConstants' trait.
This gives us typed 'SZ_*' constants (avoiding casts) for use in
device address spaces where the address width depends on the
hardware (e.g. 32-bit MMIO windows, 64-bit GPU framebuffers, etc.),
e.g.:
let gpu_heap = 14 * u64::SZ_1M;
let mmio_window = u32::SZ_16M;
- 'clk' module: implement 'Send' and 'Sync' for 'Clk' and thus
simplify the users in Tyr and PWM.
- 'ptr' module: add 'const_align_up'.
- 'str' module: improve the documentation of the 'c_str!' macro to
explain that one should only use it for non-literal cases (for the
other case we instead use C string literals, e.g. 'c"abc"').
- Disallow the use of 'CStr::{as_ptr,from_ptr}' and clean one such
use in the 'task' module.
- 'sync' module: finish the move of 'ARef' and 'AlwaysRefCounted'
outside of the 'types' module, i.e. update the last remaining
instances and finally remove the re-exports.
- 'error' module: clarify that 'from_err_ptr' can return 'Ok(NULL)',
including runtime-tested examples.
The intention is to hopefully prevent UB that assumes the result of
the function is not 'NULL' if successful. This originated from a
case of UB I noticed in 'regulator' that created a 'NonNull' on it.
Timekeeping:
- Expand the example section in the 'HrTimer' documentation.
- Mark the 'ClockSource' trait as unsafe to ensure valid values for
'ktime_get()'.
- Add 'Delta::from_nanos()'.
'pin-init' crate:
- Replace the 'Zeroable' impls for 'Option<NonZero*>' with impls of
'ZeroableOption' for 'NonZero*'.
- Improve feature gate handling for unstable features.
- Declutter the documentation of implementations of 'Zeroable' for
tuples.
- Replace uses of 'addr_of[_mut]!' with '&raw [mut]'.
rust-analyzer:
- Add type annotations to 'generate_rust_analyzer.py'.
- Add support for scripts written in Rust ('generate_rust_target.rs',
'rustdoc_test_builder.rs', 'rustdoc_test_gen.rs').
- Refactor 'generate_rust_analyzer.py' to explicitly identify host
and target crates, improve readability, and reduce duplication.
And some other fixes, cleanups and improvements"

This MDIO hardware is based on a Microsemi design supported in Linux by mdio-mscc-miim.c. However, The register interface is completely different with pic64hpsc, hence the need for separate documentation. The hardware supports C22 and C45. The documentation recommends an input clock of 156.25MHz and a prescaler of 39, which yields an MDIO clock of 1.95MHz. The hardware supports an interrupt pin to signal transaction completion which is not strictly needed as the software can also poll a "TRIGGER" bit for this.

dt-bindings: net: dsa: nxp,sja1105: make spi-cpol optional for sja1110
Currently, the binding requires 'spi-cpha' for SJA1105 and 'spi-cpol'
for SJA1110.
However, the SJA1110 supports both SPI modes 0 and 2. Mode 2
(cpha=0, cpol=1) is used by the NXP LX2160 Bluebox 3.
On the SolidRun i.MX8DXL HummingBoard Telematics, mode 0 is stable,
while forcing mode 2 introduces CRC errors especially during bursts.
Drop the requirement on spi-cpol for SJA1110.

Florian Westphal says:
====================
netfilter: updates for net-next
1-3) IPVS updates from Julian Anastasov to enhance visibility into
IPVS internal state by exposing hash size, load factor etc and
allows userspace to tune the load factor used for resizing hash
tables.
4) reject empty/not nul terminated device names from xt_physdev.
This isn't a bug fix; existing code doesn't require a c-string.
But clean this up anyway because conceptually the interface name
definitely should be a c-string.
5) Switch nfnetlink to skb_mac_header helpers that didn't exist back
when this code was written. This gives us additional debug checks
but is not intended to change functionality.
6) Let the xt ttl/hoplimit match reject unknown operator modes.
This is a cleanup, the evaluation function simply returns false when
the mode is out of range. From Marino Dzalto.
7) xt_socket match should enable defrag after all other checks. This
bug is harmless, historically defrag could not be disabled either
except by rmmod.
8) remove UDP-Lite conntrack support, from Fernando Fernandez Mancera.
9) Avoid a couple -Wflex-array-member-not-at-end warnings in the old
xtables 32bit compat code, from Gustavo A. R. Silva.
10) nftables fwd expression should drop packets when their ttl/hl has
expired. This is a bug fix deferred, its not deemed important
enough for -rc8.
11) Add additional checks before assuming the mac header is an ethernet
header, from Zhengchuan Liang.

dt-bindings: dpll: add ref-sync-sources property
Add ref-sync-sources phandle-array property to the dpll-pin schema allowing board designers to declare which input pins can serve as sync sources in a Reference-Sync pair. A Ref-Sync pair consists of a clock reference and a low-frequency sync signal where the DPLL locks to the clock but phase-aligns to the sync reference. Update both examples in the Microchip ZL3073x binding to demonstrate the new property with a 1 PPS sync source paired to a clock source.

Documentation: Add managed interrupts
I stumbled upon "isolcpus=managed_irq" which is the last piece which
can only be handled by isolcpus= and has no runtime knob. I knew roughly
what managed interrupts should do but I lacked some details how it is
used and what the managed_irq sub parameter means in practise.
This documents what we have as of today and how it works. I added some
examples how the parameter affects the configuration. Did I miss
something?
Given that the spreading as computed group_cpus_evenly() does not take
the mask of isolated CPUs into account I'm not sure how relevant the
managed_irq argument is. The virtio_scsi driver has no way to limit the
interrupts and I don't see this for the nvme. Even if the number of
queues can be reduced to two (as in the example) it is still spread
evenly in the system instead and the isolated CPUs are not taken into
account.
To make this worse, you can even argue further whether or not the
application on the isolated CPU wants to receive the interrupt directly
or would prefer not to.
Given all this, I am not sure if it makes sense to add 'io_queue' to the
mix or if it could be incorporated into 'managed_irq'.
One more point: Given that isolcpus= is marked deprecated as of commit

Pull RISC-V updates from Paul Walmsley:
"Before v7.0 is released, fix a few issues with the CFI patchset,
merged earlier in v7.0-rc, that primarily affect interfaces to
non-kernel code:
- Improve the prctl() interface for per-task indirect branch landing
pad control to expand abbreviations and to resemble the speculation
control prctl() interface
- Expand the "LP" and "SS" abbreviations in the ptrace uapi header
file to "branch landing pad" and "shadow stack", to improve
readability
- Fix a typo in a CFI-related macro name in the ptrace uapi header
file
- Ensure that the indirect branch tracking state and shadow stack
state are unlocked immediately after an exec() on the new task so
that libc subsequently can control it
- While working in this area, clean up the kernel-internal,
cross-architecture prctl() function names by expanding the
abbreviations mentioned above"

boost_freq_req QoS request to save the boost constraint instead of
overwriting the last scaling_max_freq constraint (Pierre Gondois)
- Embed cpufreq QoS freq_req objects in cpufreq policy so they all
are allocated in one go along with the policy to simplify lifetime
rules and avoid error handling issues (Viresh Kumar)
- Use DMI max speed when CPPC is unavailable in the acpi-cpufreq
scaling driver (Henry Tseng)
