tracing: Remove "__attribute__()" from the type field of event format
With CONFIG_DEBUG_INFO_BTF=y and PAHOLE_HAS_BTF_TAG=y, `__user` is
converted to `__attribute__((btf_type_tag("user")))`. In this case,
some syscall events have it for __user data, like below;
/sys/kernel/tracing # cat events/syscalls/sys_enter_openat/format
name: sys_enter_openat
ID: 720
format:
field:unsigned short common_type; offset:0; size:2; signed:0;
field:unsigned char common_flags; offset:2; size:1; signed:0;
field:unsigned char common_preempt_count; offset:3; size:1; signed:0;
field:int common_pid; offset:4; size:4; signed:1;
field:int __syscall_nr; offset:8; size:4; signed:1;
field:int dfd; offset:16; size:8; signed:0;
field:const char __attribute__((btf_type_tag("user"))) * filename; offset:24; size:8; signed:0;
field:int flags; offset:32; size:8; signed:0;
field:umode_t mode; offset:40; size:8; signed:0;
Then the trace event filter fails to set the string acceptable flag
(FILTER_PTR_STRING) to the field and rejects setting string filter;
# echo 'filename.ustring ~ "*ftracetest-dir.wbx24v*"' \
>> events/syscalls/sys_enter_openat/filter
sh: write error: Invalid argument
# cat error_log
[ 723.743637] event filter parse error: error: Expecting numeric field
Command: filename.ustring ~ "*ftracetest-dir.wbx24v*"
Since this __attribute__ makes format parsing complicated and not
needed, remove the __attribute__(.*) from the type string.

KVM/arm64 changes for 6.17, round #1
- Host driver for GICv5, the next generation interrupt controller for
arm64, including support for interrupt routing, MSIs, interrupt
translation and wired interrupts.
- Use FEAT_GCIE_LEGACY on GICv5 systems to virtualize GICv3 VMs on
GICv5 hardware, leveraging the legacy VGIC interface.
- Userspace control of the 'nASSGIcap' GICv3 feature, allowing
userspace to disable support for SGIs w/o an active state on hardware
that previously advertised it unconditionally.
- Map supporting endpoints with cacheable memory attributes on systems
with FEAT_S2FWB and DIC where KVM no longer needs to perform cache
maintenance on the address range.
- Nested support for FEAT_RAS and FEAT_DoubleFault2, allowing the guest
hypervisor to inject external aborts into an L2 VM and take traps of
masked external aborts to the hypervisor.
- Convert more system register sanitization to the config-driven
implementation.
- Fixes to the visibility of EL2 registers, namely making VGICv3 system
registers accessible through the VGIC device instead of the ONE_REG
vCPU ioctls.
- Various cleanups and minor fixes.

pwm: imx-tpm: Reset counter if CMOD is 0
As per the i.MX93 TRM, section 67.3.2.1 "MOD register update", the value
of the TPM counter does NOT get updated when writing MOD.MOD unless
SC.CMOD != 0. Therefore, with the current code, assuming the following
sequence:
1) pwm_disable()
2) pwm_apply_might_sleep() /* period is changed here */
3) pwm_enable()
and assuming only one channel is active, if CNT.COUNT is higher than the
MOD.MOD value written during the pwm_apply_might_sleep() call then, when
re-enabling the PWM during pwm_enable(), the counter will end up resetting
after UINT32_MAX - CNT.COUNT + MOD.MOD cycles instead of MOD.MOD cycles as
normally expected.
Fix this problem by forcing a reset of the TPM counter before MOD.MOD is
written.

pwm: mediatek: Fix duty and period setting
The period generated by the hardware is
(PWMDWIDTH + 1) << CLKDIV) / freq
according to my tests with a signal analyser and also the documentation.
The current algorithm doesn't consider the `+ 1` part and so configures
slightly too high periods. The same issue exists for the duty cycle
setting. So subtract 1 from both the register values for period and
duty cycle. If period is 0, bail out, if duty_cycle is 0, just disable
the PWM which results in a constant low output.

regulator: core: correct convergence check in regulator_set_voltage()
The logic in regulator_set_voltage() which checks for a non-convergence
condition on a stepped regulator is flawed.
regulator_set_voltage() checks if the error in target voltage has increased
or decreased, and returns -EWOULDBLOCK if the error has not decreased
enough. The correct non-convergence condition is:
new_delta - delta > -rdev->constraints->max_uV_step
or equivalently:
delta - new_delta < rdev->constraints->max_uV_step
But the currently used condition is:
new_delta - delta > rdev->constraints->max_uV_step
Which may cause an infinite loop if the voltage error doesn't converge.
Fix this by correcting the convergence condition.

jfs: fix metapage reference count leak in dbAllocCtl
In dbAllocCtl(), read_metapage() increases the reference count of the
metapage. However, when dp->tree.budmin < 0, the function returns -EIO

ktest.pl: Add new PATCHCHECK_SKIP option to skip testing individual commits
When testing a series of commits that also includes changes to the Linux tools directory, it is useless to test the changes in tools as they may not affect the kernel itself. Doing tests on the kernel for changes that do not affect the kernel is a waste of time. Add a PATCHCHECK_SKIP that takes a series of shas that will be skipped while doing the individual commit tests. For example, the runtime verification may have a series of commits like: $ git log --abbrev-commit --pretty=oneline fac5493251a6~1..HEAD |

WFS, and then putting the vCPU into VMX Root Mode (post-VMXON). Use the same approach KVM uses for dealing with "impossible" emulation when running a !URG guest, and simply wait until KVM_RUN to detect that the vCPU has architecturally impossible state. - Add KVM_X86_DISABLE_EXITS_APERFMPERF to allow disabling interception of APERF/MPERF reads, so that a "properly" configured VM can "virtualize" APERF/MPERF (with many caveats). - Reject KVM_SET_TSC_KHZ if vCPUs have been created, as changing the "default" frequency is unsupported for VMs with a "secure" TSC, and there's no known use case for changing the default frequency for other VM types. |

KVM IRQ changes for 6.17 - Rework irqbypass to track/match producers and consumers via an xarray instead of a linked list. Using a linked list leads to O(n^2) insertion times, which is hugely problematic for use cases that create large numbers of VMs. Such use cases typically don't actually use irqbypass, but eliminating the pointless registration is a future problem to solve as it likely requires new uAPI. - Track irqbypass's "token" as "struct eventfd_ctx *" instead of a "void *", to avoid making a simple concept unnecessarily difficult to understand. - Add CONFIG_KVM_IOAPIC for x86 to allow disabling support for I/O APIC, PIC, and PIT emulation at compile time. - Drop x86's irq_comm.c, and move a pile of IRQ related code into irq.c. - Fix a variety of flaws and bugs in the AVIC device posted IRQ code. - Inhibited AVIC if a vCPU's ID is too big (relative to what hardware supports) instead of rejecting vCPU creation. - Extend enable_ipiv module param support to SVM, by simply leaving IsRunning clear in the vCPU's physical ID table entry. - Disable IPI virtualization, via enable_ipiv, if the CPU is affected by erratum #1235, to allow (safely) enabling AVIC on such CPUs. - Dedup x86's device posted IRQ code, as the vast majority of functionality can be shared verbatime between SVM and VMX. - Harden the device posted IRQ code against bugs and runtime errors. - Use vcpu_idx, not vcpu_id, for GA log tag/metadata, to make lookups O(1) instead of O(n). - Generate GA Log interrupts if and only if the target vCPU is blocking, i.e. only if KVM needs a notification in order to wake the vCPU. - Decouple device posted IRQs from VFIO device assignment, as binding a VM to a VFIO group is not a requirement for enabling device posted IRQs. - Clean up and document/comment the irqfd assignment code. - Disallow binding multiple irqfds to an eventfd with a priority waiter, i.e. ensure an eventfd is bound to at most one irqfd through the entire host, and add a selftest to verify eventfd:irqfd bindings are globally unique. |

block: Improve read ahead size for rotational devices
For a device that does not advertize an optimal I/O size, the function blk_apply_bdi_limits() defaults to an initial setting of the ra_pages field of struct backing_dev_info to VM_READAHEAD_PAGES, that is, 128 KB. This low I/O size value is far from being optimal for hard-disk devices: when reading files from multiple contexts using buffered I/Os, the seek overhead between the small read commands generated to read-ahead multiple files will significantly limit the performance that can be achieved. This fact applies to all ATA devices as ATA does not define an optimal I/O size and the SCSI SAT specification does not define a default value to expose to the host. Modify blk_apply_bdi_limits() to use a device max_sectors limit to calculate the ra_pages field of struct backing_dev_info, when the device is a rotational one (BLK_FEAT_ROTATIONAL feature is set). For a SCSI disk, this defaults to 2560 KB, which significantly improve performance for buffered reads. Using XFS and sequentially reading randomly selected (large) files stored on a SATA HDD, the maximum throughput achieved with 8 readers reading files with 1MB buffered I/Os increases from 122 MB/s to 167 MB/s (+36%). The improvement is even larger when reading files using 128 KB buffered I/Os, with a throughput increasing from 57 MB/s to 165 MB/s (+189%).

drm/i915/display: Avoid unnecessarily calling intel_cx0_get_owned_lane_mask
Currently we are always calling intel_cx0_get_owned_lane_mask when
intel_lnl_mac_transmit_lfps is called. Avoid this in cases where it's not
needed.

drm/i915/display: Write PHY_CMN1_CONTROL only when using AUXLess ALPM
We are seeing "dmesg-warn/abort - *ERROR* PHY * failed after 3 retries" since we started configuring LFPS sending. According to Bspec Configuring LFPS sending is needed only when using AUXLess ALPM. This patch avoids these failures by configuring LFPS sending only when using AUXLess ALPM. Bspec: 68849 Fixes: |

tracing: fprobe: Fix infinite recursion using preempt_*_notrace()
Since preempt_count_add/del() are tracable functions, it is not allowed
to use preempt_disable/enable() in ftrace handlers. Without this fix,
probing on `preempt_count_add%return` will cause an infinite recursion
of fprobes.
To fix this problem, use preempt_disable/enable_notrace() in
fprobe_return().

This release is almost entirely driver work, mostly new drivers with the
usual smattering of per driver updates anf fixes, with only trivial
changes in the core. Highlights include:
- Quite a bit of maintainence work on the STM32 and Qualcomm drivers.
- Usage of the newly added devm_dma_request_chan() in the ateml driver,
pulling in the relevant dmaengine change.
- Cleanups of our usage of the PM autosuspend functions, this pulls in
some PM core changes on a shared tag.
- Support for ADI sigma-delta triggers, Amlogic SPISG, Mediatek MT6991
and MT8196, Renesas RZ/V2H(P) and SOPHGO SG2042.

regulator: Updates for v6.17
The big change in this release is the addition of Rust bindings from
Daniel Almeida, allowing fairly basic consumer use with support for
enable and voltage setting operations. This should be good for the vast
majority of consumers. Otherwise it's been quite quiet, a few new
devices supported, plus some cleanups and fixes.
- Basic Rust bindings.
- A fix for making large voltage changes on regulators where we limit
the size of voltage change we will do in one step, previously we just
got as close as we could in one step.
- Cleanups of our usage of the PM autosuspend functions, this pulls in
some PM core changes on a shared tag.
- Mode setting support for PCA9450.
- Support for Mediatek MT6893 and MT8196 DVFSRC, Qualcomm PM7550 and
PMR735B, Raspberry Pi displays and TI TPS652G1.
The TI driver pulls in the MFD portion of the support for the device and
the pinctrl driver which was in the same tag.

gpio updates for v6.17-rc1
GPIOLIB core:
- introduce a parallel, limited sysfs user ABI that doesn't expose the
global GPIO numbers to user-space while maintaining backward
compatibility with the end goal of it completely replacing the existing
interface, allowing us to remove it
- remove the legacy devm_gpio_request() routine which has no more users
- start the process of allowing to compile-out the legacy parts of the
GPIO core for users who don't need it by introducing a new Kconfig
option: GPIOLIB_LEGACY
- don't use global GPIO numbers in debugfs output from the core code
(drivers still do it, the work is ongoing)
- start the process of moving the fields specific to the gpio-mmio helper
out of the core struct gpio_chip into their own structure that wraps
it: create a new header with modern interfaces and convert several
drivers to using it
- remove the platform data structure associated with the gpio-mmio helper
from the kernel after having converted all remaining users to generic
device properties
- remove legacy struct gpio definition as it has no more users
New drivers:
- add the GPIO driver for the Apple System Management Controller
Driver improvements:
- add support for new models to gpio-adp5585, gpio-tps65219 and
gpio-pca953x
- extend the interrupt support in gpio-loongson-64bit
- allow to mark the simulated GPIO lines as invalid in gpio-sim
- convert all remaining GPIO drivers to using the new GPIO value setter
callbacks
- convert gpio-rcar to using simple device power management ops callbacks
- don't check if current direction of a line is output before setting
the value in gpio-pisosr and ti-fpc202: the GPIO core already handles
that
- also drop unneeded GPIO range checks in drivers, the core already makes
sure we're within bounds when calling driver callbacks
- use dev_fwnode() where applicable across GPIO drivers
- set line value in gpio-zynqmp-modepin and gpio-twl6040 when the user
wants to change direction of the pin to output even though these
drivers don't need to do anything else to actually set the direction,
otherwise a call like gpiod_direction_output(d, 1) will not result in
the line driver high
- remove the reduntant call to pm_runtime_mark_last_busy() from
gpio-arizona
- use lock guards in gpio-cadence and gpio-mxc
- check the return values of regmap functions in gpio-wcd934x and
gpio-tps65912
- use better regmap interfaces in gpio-wcove and gpio-pca953x
- remove dummy GPIO chip callbacks from several drivers in cases where
the GPIO core can already handle their absence
- allow building gpio-palmas as a module
Fixes:
- use correct bit widths (according to the documentation) in gpio-virtio
Device-tree bindings:
- convert several of the legacy .txt documents for many different devices
to YAML, improving automatic validation
- create a "trivial" GPIO DT schema that covers a wide range of simple
hardware that share a set of basic GPIO properties
- document new HW: Apple MAC SMC GPIO block and adp5589 I/O expander
- document a new model for pca95xx
- add and/or remove properties in YAML documents for gpio-rockchip,
fsl,qoriq-gpio, arm,pl061 and gpio-xilinx
Misc:
- some minor refactoring in several places, adding/removing forward
declarations, moving defines to better places, constify the arguments
in some functions, remove duplicate includes, etc.
- documentation updates

Pull gpio updates from Bartosz Golaszewski:
"There's one new driver (Apple SMC) and extensions to existing drivers
for supporting new HW models. A lot of different impovements across
drivers and in core GPIO code. Details on that are in the signed tag
as usual.
We managed to remove some of the legacy APIs. Arnd Bergmann started to
work on making the legacy bits optional so that we may compile them
only for older platforms that still really need them.
Rob Herring has done a lot of work to convert legacy .txt dt-bindings
for GPIO controllers to YAML. There are only a few left now in the
GPIO tree.
A big part of the commits in this PR concern the conversion of GPIO
drivers to using the new line value setter callbacks. This conversion
is now complete treewide (unless I've missed something) and once all
the changes from different trees land in mainline, I'll send you
another PR containing a commit dropping the legacy callbacks from the
tree.
As the quest to pay back technical dept never really ends, we're
starting another set of interface conversions, this time it's about
moving fields specific to only a handful of drivers using the
gpio-mmio helper out of the core gpio_chip structure that every
controller implements and uses. This cycle we introduce a new set of
APIs and convert a few drivers under drivers/gpio/, next cycle we'll
convert remaining modules treewide (in gpio, pinctrl and mfd trees)
and finally remove the old interfaces and move the gpio-mmio fields
into their own structure wrapping gpio_chip.
One last change I should mention here is the rework of the sysfs
interface. In 2016, we introduced the GPIO character device as the
preferred alternative to the sysfs class under /sys/class/gpio. While
it has seen a wide adoption with the help of its user-space
counterpart - libgpiod - there are still users who prefer the
simplicity of sysfs.
As far as the GPIO subsystem is concerned, the problem is not the
existince of the GPIO class as such but rather the fact that it
exposes the global GPIO numbers to the user-space, stopping us from
ever being able to remove the numberspace from the kernel. To that
end, this release we introduced a parallel, limited sysfs interface
that doesn't expose these numbers and only implements a subset of
features that are relevant to the existing users. This is a result of
several discussions over the course of last year and should allow us
to remove the legacy part some time in the future.

sound updates for 6.17-rc1
This includes lots of file shuffling due to HD-audio code
reorganization and many trivial changes, but otherwise there shouldn't
be much surprise from the functionality POV. The PR includes the PM
changes as prerequisite, too. Some highlights below:
Core:
- Performance optimizations in PCM core code
- Refactoring of ASoC Kconfig menus to be hopefully more consistant
and easier to navigate.
- Refactoring of ASoC DAPM code, mainly hiding functionality that
doesn't need to be exposed to drivers
HD-audio reorganization:
- All code are moved under sound/hda with a bit more understandable
tree structure, as well as file renames
- The huge Realtek driver code is split to several parts, a common
helper module with driver modules per probe entry
- HDMI and Cirrus codec drivers also split
ASoC:
- Further work on the generic handling for SoundWire SDCA devices
- Support for AMD ACP7.2 and SoundWire on ACP 7.1, Fairphone 4 & 5,
various Intel systems, Qualcomm QCS8275, Richtek RTQ9124 and TI
TAS5753
HD-audio and USB-audio:
- TAS2781 driver cleanup and TAS2770 support
- EQ enablement in CA0132 driver
- USB audio quirk code cleanups
Others:
- Cleanups of PM autosuspend call patterns with the update from the PM
tree
- Lots of strcpy() -> strscpy() conversions for fixed size arrays

Pull power management updates from Rafael Wysocki:
"As is tradition, cpufreq is the part with the largest number of
updates that include core fixes and cleanups as well as updates of
several assorted drivers, but there are also quite a few updates
related to system sleep, mostly focused on asynchronous suspend and
resume of devices and on making the integration of system suspend
and resume with runtime PM easier.
Runtime PM is also updated to allow some code duplication in drivers
to be eliminated going forward and to work more consistently overall
in some cases.
Apart from that, there are some driver core updates related to PM
domains that should help to address ordering issues with devm_ cleanup
routines relying on PM domains, some assorted devfreq updates
including core fixes and cleanups, tooling updates, and documentation
and MAINTAINERS updates.
Specifics:
- Fix two initialization ordering issues in the cpufreq core and a
governor initialization error path in it, and clean it up (Lifeng
