Bean Huo <beanhuo@iokpp.de> says:
Adding RTC support for embedded storage device UFS in its driver, it
is important for a few key reasons:
1. Helps with Regular Maintenance:
The RTC provides a basic way to keep track of time, making it useful for
scheduling routine maintenance tasks in the storage device. This includes
things like making sure data is spread
evenly across the storage to extend its life.
2. Figuring Out How Old Data Is:
The RTC helps the device estimate how long ago certain parts of the storage
were last used. This is handy for deciding when to do maintenance tasks to
keep the storage working well over time.
3. Making Devices Last Longer:
By using the RTC for regular upkeep, we can make sure the storage device lasts
longer and stays reliable. This is especially important for devices that need
to work well for a long time.
4.Fitting In with Other Devices:
The inclusion of RTC support aligns with existing UFS specifications (starting
from UFS Spec 2.0) and is consistent with the prevalent industry practice. Many
UFS devices currently on the market utilize RTC for internal timekeeping. By
ensuring compatibility with this widely adopted standard, the embedded storage
device becomes seamlessly integrable with existing hardware and software
ecosystems, reducing the risk of compatibility issues.
In short, adding RTC support to embedded storage device UFS helps with regular
upkeep, extends the device's life, ensures compatibility, and keeps everything
running smoothly with the rest of the system.

Introduce a sysfs node named 'rtc_update_ms' within the kernel, enabling
user to adjust the RTC periodic update frequency to suit the specific
requirements of the system and UFS. Also, this patch allows the user to
disable/enable periodic update RTC in the UFS idle time.

The serial tty interface also supports additional input signals, that
can also be evaluated within this trigger. This change is adding the
following additional input sources, which could be controlled
via the '/sys/class/<leds>/' sysfs interface.
Explanation:
DCE = Data Communication Equipment (Modem)
DTE = Data Terminal Equipment (Computer)
- cts:
DCE is ready to accept data from the DTE (CTS = Clear To Send). If
the line state is detected, the LED is switched on.
If set to 0 (default), the LED will not evaluate CTS.
If set to 1, the LED will evaluate CTS.
- dsr:
DCE is ready to receive and send data (DSR = Data Set Ready). If the
line state is detected, the LED is switched on.
If set to 0 (default), the LED will not evaluate DSR.
If set to 1, the LED will evaluate DSR.
- dcd:
DTE is receiving a carrier from the DCE (DCD = Data Carrier Detect).
If the line state is detected, the LED is switched on.
If set to 0 (default), the LED will not evaluate DCD.
If set to 1, the LED will evaluate DCD.
- rng:
DCE has detected an incoming ring signal on the telephone line
(RNG = Ring Indicator). If the line state is detected, the LED is
switched on.
If set to 0 (default), the LED will not evaluate RNG.
If set to 1, the LED will evaluate RNG.
Also add an invert flag on LED blink, so that the LED blinks in the
correct order.
* If one off the new enabled input signals are evaluatet as 'enabled',
and data are transmitted, then the LED should first blink 'off' and
then 'on' (invert).
* If all the new enabled input signals are evaluatet as 'disabled',
and data are transmitted, then the LED should first blink 'on' and
then 'off'.

Until now, the LED blinks when data is sent via the tty (rx/tx).
This is not configurable.
This change adds the possibility to make the indication for the direction
of the transmitted data independently controllable via the new rx and
tx sysfs entries.
- rx:
Signal reception (rx) of data on the named tty device.
If set to 0, the LED will not blink on reception.
If set to 1 (default), the LED will blink on reception.
- tx:
Signal transmission (tx) of data on the named tty device.
If set to 0, the LED will not blink on transmission.
If set to 1 (default), the LED will blink on transmission.
This new sysfs entry are on by default. Thus the trigger behaves as
before this change.

Preliminary step to add the missing humidity attributes in the ABI

Adding new elements alphabetically is a common practice that has been
loosely followed in the sysfs-class-hwmon documentation. Since most of
the humidity attributes must be added to the file, a single attribute
needs to be rearranged to reinforce alphabetical order.

The commit c7d80059b0 ("leds: class: Store the color index in struct
led_classdev") introduced a new sysfs entry "color" that is commonly
created for the led classdev. Unfortunately, this conflicts with the
"color" sysfs entry of already existing drivers such as Logitech HID
or System76 ACPI drivers. The driver probe fails due to the conflict,
hence it leads to a severe regression with the missing keyboard, for
example.
This patch reverts partially the change in the commit above for
removing the led class color sysfs entries again for addressing the
regressions. The newly introduced led_classdev.color field is kept as
it's already used by other driver.

Currently TMC-ETR automatically selects the buffer mode from all available
methods in the following sequentially fallback manner - also in that order.
1. FLAT mode with or without IOMMU
2. TMC-ETR-SG (scatter gather) mode when available
3. CATU mode when available
But this order might not be ideal for all situations. For example if there
is a CATU connected to ETR, it may be better to use TMC-ETR scatter gather
method, rather than CATU. But hard coding such order changes will prevent
us from testing or using a particular mode. This change provides following
new sysfs tunables for the user to control TMC-ETR buffer mode explicitly,
if required. This adds following new sysfs files for buffer mode selection
purpose explicitly in the user space.
/sys/bus/coresight/devices/tmc_etr<N>/buf_modes_available
/sys/bus/coresight/devices/tmc_etr<N>/buf_mode_preferred
$ cat buf_modes_available
auto flat tmc-sg catu ------------------> Supported TMC-ETR buffer modes
$ echo catu > buf_mode_preferred -------> Explicit buffer mode request
But explicit user request has to be within supported ETR buffer modes only.
These sysfs interface files are exclussive to ETR, and hence these are not
available for other TMC devices such as ETB or ETF etc.
A new auto' mode (i.e ETR_MODE_AUTO) has been added to help fallback to the
existing default behaviour, when user provided preferred buffer mode fails.
ETR_MODE_FLAT and ETR_MODE_AUTO are always available as preferred modes.

Pull CXL (Compute Express Link) updates from Dan Williams:
"The main new functionality this time is work to allow Linux to
natively handle CXL link protocol errors signalled via PCIe AER for
current generation CXL platforms. This required some enlightenment of
the PCIe AER core to workaround the fact that current generation RCH
(Restricted CXL Host) platforms physically hide topology details and
registers via a mechanism called RCRB (Root Complex Register Block).
The next major highlight is reworks to address bugs in parsing region
configurations for next generation VH (Virtual Host) topologies. The
old broken algorithm is replaced with a simpler one that significantly
increases the number of region configurations supported by Linux. This
is again relevant for error handling so that forward and reverse
address translation of memory errors can be carried out by Linux for
memory regions instantiated by platform firmware.
As for other cross-tree work, the ACPI table parsing code has been
refactored for reuse parsing the "CDAT" structure which is an
ACPI-like data structure that is reported by CXL devices. That work is
in preparation for v6.8 support for CXL QoS. Think of this as dynamic
generation of NUMA node topology information generated by Linux rather
than platform firmware.
Lastly, a number of internal object lifetime issues have been resolved
along with misc. fixes and feature updates (decoders_committed sysfs
ABI).
Summary:
- Add support for RCH (Restricted CXL Host) Error recovery
- Fix several region assembly bugs
- Fix mem-device lifetime issues relative to the sanitize command and

Pull unified attestation reporting from Dan Williams:
"In an ideal world there would be a cross-vendor standard attestation
report format for confidential guests along with a common device
definition to act as the transport.
In the real world the situation ended up with multiple platform
vendors inventing their own attestation report formats with the
SEV-SNP implementation being a first mover to define a custom
sev-guest character device and corresponding ioctl(). Later, this
configfs-tsm proposal intercepted an attempt to add a tdx-guest
character device and a corresponding new ioctl(). It also anticipated
ARM and RISC-V showing up with more chardevs and more ioctls().
The proposal takes for granted that Linux tolerates the vendor report
format differentiation until a standard arrives. From talking with
folks involved, it sounds like that standardization work is unlikely
to resolve anytime soon. It also takes the position that kernfs ABIs
are easier to maintain than ioctl(). The result is a shared configfs
mechanism to return per-vendor report-blobs with the option to later
support a standard when that arrives.
Part of the goal here also is to get the community into the
"uncomfortable, but beneficial to the long term maintainability of the
kernel" state of talking to each other about their differentiation and
opportunities to collaborate. Think of this like the device-driver
equivalent of the common memory-management infrastructure for
confidential-computing being built up in KVM.
As for establishing an "upstream path for cross-vendor
confidential-computing device driver infrastructure" this is something
I want to discuss at Plumbers. At present, the multiple vendor
proposals for assigning devices to confidential computing VMs likely
needs a new dedicated repository and maintainer team, but that is a
discussion for v6.8.
For now, Greg and Thomas have acked this approach and this is passing
is AMD, Intel, and Google tests.

Here is the "big" set of USB and Thunderbolt changes for 6.7-rc1.
Nothing really major in here, just lots of constant development for new
hardware. Included in here are:
- Thunderbolt (i.e. USB4) fixes for reported issues and support for
new hardware types and devices
- USB typec additions of new drivers and cleanups for some existing
ones
- xhci cleanups and expanded tracing support and some platform
specific updates
- USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio, spi,
and i2c drivers for that type of device (all acked by the respective
subsystem maintainers.)
- lots of USB gadget driver updates and cleanups
- new USB dwc3 platforms supported, as well as other dwc3 fixes and
cleanups
- USB chipidea driver updates
- other smaller driver cleanups and additions, full details in the
shortlog
All of these have been in the linux-next tree for a while with no
reported problems, EXCEPT for some merge conflicts that you will run
into in your tree. 2 of them are in device-tree files, which will be
trivial to resolve (accept both sides), and the last in the
drivers/gpio/gpio-ljca.c file, in the remove callback, resolution should
be pretty trivial (take the version in this branch), see here:
https://lore.kernel.org/all/20231016134159.11d8f849@canb.auug.org.au/

Currently supplicant dependent optee device enumeration only registers
devices whenever tee-supplicant is invoked for the first time. But it
forgets to remove devices when tee-supplicant daemon stops running and
closes its context gracefully. This leads to following error for fTPM
driver during reboot/shutdown:
[ 73.466791] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024
Fix this by adding an attribute for supplicant dependent devices so that
the user-space service can detect and detach supplicant devices before
closing the supplicant:
$ for dev in /sys/bus/tee/devices/*; do if [[ -f "$dev/need_supplicant" && -f "$dev/driver/unbind" ]]; \
then echo $(basename "$dev") > $dev/driver/unbind; fi done

newer boards).
Determine whether the gamma correction setting feature is supported and
add the ability to set it via sysfs attribute file.

Currently, the additional information of a branch entry is stored in a
u64 space. With more and more information added, the space is running
out. For example, the information of occurrences of events will be added
for each branch.
Two places were suggested to append the counters.
https://lore.kernel.org/lkml/20230802215814.GH231007@hirez.programming.kicks-ass.net/
One place is right after the flags of each branch entry. It changes the
existing struct perf_branch_entry. The later ARCH specific
implementation has to be really careful to consistently pick
the right struct.
The other place is right after the entire struct perf_branch_stack.
The disadvantage is that the pointer of the extra space has to be
recorded. The common interface perf_sample_save_brstack() has to be
updated.
The latter is much straightforward, and should be easily understood and
maintained. It is implemented in the patch.
Add a new branch sample type, PERF_SAMPLE_BRANCH_COUNTERS, to indicate
the event which is recorded in the branch info.
The "u64 counters" may store the occurrences of several events. The
information regarding the number of events/counters and the width of
each counter should be exposed via sysfs as a reference for the perf
tool. Define the branch_counter_nr and branch_counter_width ABI here.
The support will be implemented later in the Intel-specific patch.

Add an interface for the rate limiting feature which allows to add,
remove and modify a QAT SLA (Service Level Agreement).
This adds a new sysfs attribute group, `qat_rl`, which can be accessed
from /sys/bus/pci/devices/<BUS:DEV:FUNCTION> with the following
hierarchy:
|-+ qat_rl
|---- id (RW) # SLA identifier
|---- cir (RW) # Committed Information Rate
|---- pir (RW) # Peak Information Rate
|---- srv (RW) # Service to be rate limited
|---- rp (RW) (HEX) # Ring pairs to be rate limited
|---- cap_rem (RW) # Remaining capability for a service
|---- sla_op (WO) # Allows to perform an operation on an SLA
The API works by setting the appropriate RW attributes and then
issuing a command through the `sla_op`. For example, to create an SLA, a
user needs to input the necessary data into the attributes cir, pir, srv
and rp and then write into `sla_op` the command `add` to execute the
operation.
The API also provides `cap_rem` attribute to get information about
the remaining device capability within a certain service which is
required when setting an SLA.

Particularly great to see a resolver driver move out of staging via a
massive set of changes. Only took 13 years :)
One small patch added then reverted due to a report of test breakage
(ashai-kasei,ak8975: Drop deprecated enums.)
An immutable branch was used for some hid-senors changes in case
there was a need to take them into the HID tree as well.
New device support
-----------------
adi,hmc425a
- Add support for HMC540SLP3E broadband 4-bit digital attenuator.
kionix,kx022a
- Add support for the kx132-1211 accelerometer. Require significant
driver rework to enable this including add a chip type specific
structure to deal with the chip differences.
- Add support for the kx132acr-lbz accelerometer (subset of the kx022a
feature set).
lltc,ltc2309
- New driver for this 8 channel ADC.
microchip,mcp3911
- Add support for rest of mcp391x family of ADCs (there are various
differences beyond simple channel count variation.
Series includes some general driver cleanup.
microchip,mcp3564
- New driver for MCP3461, MCP3462, MCP3464, MCP3541, MCP3562, MCP3564
and their R variants of 16/24bit ADCs. A few minor fixed followed.
rohm,bu1390
- New driver for this pressure sensor.
Staging graduation
------------------
adi,ad1210 (after 13 or so years :)
- More or less a complete (step-wise) rewrite of this resolver driver
to bring it up to date with modern IIO standards. The fault signal
handling mapping to event channels was particularly complex and
significant part of the changes.
Features
--------
iio-core
- Add chromacity and color temperature channel types.
adi,ad7192
- Oversampling ratio control (called fast settling in datasheet).
adi,adis16475
- Add core support and then driver support for delta angle and delta
velocity channels. These are intended for summation to establish
angle and velocity changes over larger timescales. Fix was
needed for alignment after the temperature channel. Further fix
reduced set of devices for which the buffer support was applicable
as seems burst reads don't cover these on all devices.
hid-sensors-als
- Chromacity and color temperatures support including in amd sfh.
stx104
- Add support for counter subsystem to this multipurpose device.
ti,twl6030
- Add missing device tree binding description.
Clean up and minor fixes.
------------------------
treewide
- Drop some unused declarations across IIO.
- Make more use of device_get_match_data() instead of OF specific
approaches.
Similar cleanup to sets of drivers.
- Stop platform remove callbacks returning anything by using the
temporary remove_new() callback.
- Use i2c_get_match_data() to cope nicely with all types of ID table
entry.
- Use device_get_match_data() for various platform device to cope
with more types of firmware.
- Convert from enum to pointer in ID tables allowing use of
i2c_get_match_data().
- Fix sorting on some ID tables.
- Include specific string helper headers rather than simply string_helpers.h
docs
- Better description of the ordering requirements etc for
available_scan_masks.
tools
- Handle alignment of mixed sizes where the last element isn't the biggest
correctly. Seems that doesn't happen often!
adi,ad2s1210
- Lots of work from David Lechner on this driver including a few fixes
that are going with the rework to avoid slowing that down.
adi,ad4310
- Replace deprecated devm_clk_register()
adi,ad74413r
- Bring the channel function setting inline with the datasheet.
adi,ad7192
- Change to FIELD_PREP(), FIELD_GET().
- Calculate f_order from the sinc filter and chop filter states.
- Move more per chip config into data in struct ad7192_chip_info
- Cleanup unused parameter in channel macros.
adi,adf4350
- Make use of devm_* to simplify error handling for many of the setup
calls in probe() / tear down in remove() and error paths. Some more
work to be done on this one.
- Use dev_err_probe() for errors in probe() callback.
adi,adf4413
- Typo in function name prefix.
adi,adxl345
- Add channel scale to the chip type specific structure and drop
using a type field previously used for indirection.
asahi,ak8985
- Fix a mismatch introduced when switching from enum->pointers
in the match tables.
amlogic,meson
- Expand error logging during probe.
invensense,mpu6050
- Support level-shifter control. Whilst no one is sure exactly what this
is doing it is needed for some old boards.
- Document mount-matrix dt-binding.
mediatek,mt6577
- Use devm_clk_get_enabled() to replace open coded version and move
everything over to being device managed. Drop now empty remove()
callback. Fix follows to put the drvdata back.
- Use dev_err_probe() for error reporting in probe() callback.
memsic,mxc4005
- Add of_match_table.
microchip,mcp4725
- Move various chip specific data from being looked up by chip ID to
data in the chip type specific structure.
silicon-labs,si7005
- Add of_match_table and entry in trivial-devices.yaml
st,lsm6dsx
- Add missing mount-matrix dt binding documentation.
st,spear
- Use devm_clk_get_enabled() and some other devm calls to move everything
over to being device managed. Drop now empty remove() callback.
- Use dev_err_probe() to better handled deferred probing and tidy up
error reporting in probe() callback.
st,stm32-adc
- Add a bit of additional checking in probe() to protect against a NULL
pointer (no known path to trigger it today).
- Replace deprecated strncpy()
ti,ads1015

to bring it up to date with modern IIO standards. The fault signal
handling mapping to event channels was particularly complex and
significant part of the changes.
Features
--------
iio-core
- Add chromacity and color temperature channel types.
adi,ad7192
- Oversampling ratio control (called fast settling in datasheet).
adi,adis16475
- Add core support and then driver support for delta angle and delta
velocity channels. These are intended for summation to establish
angle and velocity changes over larger timescales. Fix was
needed for alignment after the temperature channel. Further fix
reduced set of devices for which the buffer support was applicable
as seems burst reads don't cover these on all devices.
hid-sensors-als
- Chromacity and color temperatures support including in amd sfh.
stx104
- Add support for counter subsystem to this multipurpose device.
ti,twl6030
- Add missing device tree binding description.
Clean up and minor fixes.
------------------------
treewide
- Drop some unused declarations across IIO.
- Make more use of device_get_match_data() instead of OF specific
approaches.
Similar cleanup to sets of drivers.
- Stop platform remove callbacks returning anything by using the
temporary remove_new() callback.
- Use i2c_get_match_data() to cope nicely with all types of ID table
entry.
- Use device_get_match_data() for various platform device to cope
with more types of firmware.
- Convert from enum to pointer in ID tables allowing use of
i2c_get_match_data().
- Fix sorting on some ID tables.
- Include specific string helper headers rather than simply string_helpers.h
docs
- Better description of the ordering requirements etc for
available_scan_masks.
tools
- Handle alignment of mixed sizes where the last element isn't the biggest
correctly. Seems that doesn't happen often!
adi,ad2s1210
- Lots of work from David Lechner on this driver including a few fixes
that are going with the rework to avoid slowing that down.
adi,ad4310
- Replace deprecated devm_clk_register()
adi,ad74413r
- Bring the channel function setting inline with the datasheet.
adi,ad7192
- Change to FIELD_PREP(), FIELD_GET().
- Calculate f_order from the sinc filter and chop filter states.
- Move more per chip config into data in struct ad7192_chip_info
- Cleanup unused parameter in channel macros.
adi,adf4350
- Make use of devm_* to simplify error handling for many of the setup
calls in probe() / tear down in remove() and error paths. Some more
work to be done on this one.
- Use dev_err_probe() for errors in probe() callback.
adi,adf4413
- Typo in function name prefix.
adi,adxl345
- Add channel scale to the chip type specific structure and drop
using a type field previously used for indirection.
asahi,ak8985
- Fix a mismatch introduced when switching from enum->pointers
in the match tables.
amlogic,meson
- Expand error logging during probe.
invensense,mpu6050
- Support level-shifter control. Whilst no one is sure exactly what this
is doing it is needed for some old boards.
- Document mount-matrix dt-binding.
mediatek,mt6577
- Use devm_clk_get_enabled() to replace open coded version and move
everything over to being device managed. Drop now empty remove()
callback. Fix follows to put the drvdata back.
- Use dev_err_probe() for error reporting in probe() callback.
memsic,mxc4005
- Add of_match_table.
microchip,mcp4725
- Move various chip specific data from being looked up by chip ID to
data in the chip type specific structure.
silicon-labs,si7005
- Add of_match_table and entry in trivial-devices.yaml
st,lsm6dsx
- Add missing mount-matrix dt binding documentation.
st,spear
- Use devm_clk_get_enabled() and some other devm calls to move everything
over to being device managed. Drop now empty remove() callback.
- Use dev_err_probe() to better handled deferred probing and tidy up
error reporting in probe() callback.
st,stm32-adc
- Add a bit of additional checking in probe() to protect against a NULL
pointer (no known path to trigger it today).
- Replace deprecated strncpy()
ti,ads1015
- Allow for edge triggers.
- Document interrupt in dt-bindings.

One of the common operations of a TSM (Trusted Security Module) is to
provide a way for a TVM (confidential computing guest execution
environment) to take a measurement of its launch state, sign it and
submit it to a verifying party. Upon successful attestation that
verifies the integrity of the TVM additional secrets may be deployed.
The concept is common across TSMs, but the implementations are
unfortunately vendor specific. While the industry grapples with a common
definition of this attestation format [1], Linux need not make this
problem worse by defining a new ABI per TSM that wants to perform a
similar operation. The current momentum has been to invent new ioctl-ABI
per TSM per function which at best is an abdication of the kernel's
responsibility to make common infrastructure concepts share common ABI.
The proposal, targeted to conceptually work with TDX, SEV-SNP, COVE if
not more, is to define a configfs interface to retrieve the TSM-specific
blob.
report=/sys/kernel/config/tsm/report/report0
mkdir $report
dd if=binary_userdata_plus_nonce > $report/inblob
hexdump $report/outblob
This approach later allows for the standardization of the attestation
blob format without needing to invent a new ABI. Once standardization
happens the standard format can be emitted by $report/outblob and
indicated by $report/provider, or a new attribute like
"$report/tcg_coco_report" can emit the standard format alongside the
vendor format.
Review of previous iterations of this interface identified that there is
a need to scale report generation for multiple container environments
[2]. Configfs enables a model where each container can bind mount one or
more report generation item instances. Still, within a container only a
single thread can be manipulating a given configuration instance at a
time. A 'generation' count is provided to detect conflicts between
multiple threads racing to configure a report instance.
The SEV-SNP concepts of "extended reports" and "privilege levels" are
optionally enabled by selecting 'tsm_report_ext_type' at register_tsm()
time. The expectation is that those concepts are generic enough that
they may be adopted by other TSM implementations. In other words,
configfs-tsm aims to address a superset of TSM specific functionality
with a common ABI where attributes may appear, or not appear, based on
the set of concepts the implementation supports.

On Lenovo platforms there is a limitation in the number of times an
attribute can be saved. This is an architectural limitation and it limits
the number of attributes that can be modified to 48.
A solution for this is instead of the attribute being saved after every
modification allow a user to bulk set the attributes and then trigger a
final save. This allows unlimited attributes.
This patch introduces a save_settings attribute that can be configured to
either single or bulk mode by the user.
Single mode is the default but customers who want to avoid the 48
attribute limit can enable bulk mode.
Displaying the save_settings attribute will display the enabled mode.
When in bulk mode writing 'save' to the save_settings attribute will
trigger a save. Once this has been done a reboot is required before more
attributes can be modified.

QAT GEN4 devices support chained compression operations. These
allow, with a single request to firmware, to hash then compress
data.
Extend the configuration to enable such mode. The cfg_services
operations in sysfs are extended to allow the string "dcc". When
selected, the driver downloads to the device both the symmetric
crypto and the compression firmware images and sends an admin message
to firmware which enables `chained` operations.
In addition, it sets the device's capabilities as the combination
of compression and symmetric crypto capabilities, while excluding
the ICP_ACCEL_CAPABILITIES_CRYPTO_SYMMETRIC bit to indicate
that in this mode, symmetric crypto instances are not supported.
When "dcc" is enabled, the device will handle compression requests
as if the "dc" configuration is loaded ("dcc" is a variation of "dc")
and the driver will register the acomp algorithms.
As for the other extended configurations, "dcc" is only available for
qat_4xxx devices and the chaining service will be only accessible from
user space.

In this cycle, we don't have a highlighted feature enhancement, but mostly
have fixed issues mainly in two parts: 1) zoned block device, 2) compression
support. For zoned block device, we've tried to improve the power-off recovery
flow as much as possible. For compression, we found some corner cases caused by
wrong compression policy and logics. Other than them, there were some reverts
and stat corrections.
Bug fix:
- use finish zone command when closing a zone
- check zone type before sending async reset zone command
- fix to assign compress_level for lz4 correctly
- fix error path of f2fs_submit_page_read()
- don't {,de}compress non-full cluster
- send small discard commands during checkpoint back
- flush inode if atomic file is aborted
- correct to account gc/cp stats
And, there are minor bug fixes, avoiding false lockdep warning, and clean-ups.

Pull powerpc updates from Michael Ellerman:
- Add HOTPLUG_SMT support (/sys/devices/system/cpu/smt) and honour the
configured SMT state when hotplugging CPUs into the system
- Combine final TLB flush and lazy TLB mm shootdown IPIs when using the
Radix MMU to avoid a broadcast TLBIE flush on exit
- Drop the exclusion between ptrace/perf watchpoints, and drop the now
unused associated arch hooks
- Add support for the "nohlt" command line option to disable CPU idle
- Add support for -fpatchable-function-entry for ftrace, with GCC >=
13.1
- Rework memory block size determination, and support 256MB size on
systems with GPUs that have hotpluggable memory
- Various other small features and fixes

The main change this time is the introduction of the drivers/genpd
subsystem that gets split out from drivers/soc to keep common
functionality together. Ulf Hansson is taking over maintainership for
these and is sending a separate pull request with the same commits,
but they are in the soc drivers tree to avoid conflicts against other
soc driver patches.
The SCMI driver subsystem gets an update to version 3.2 of the
specification. There are also updates to memory, reset and other firmware
drivers.
On the soc driver side, the updates are mostly cleanups across a number
of Arm platforms. On driver for loongarch adds power management for DT
based systems, another driver is for HiSilicon's Arm server chips with
their HCCS system health interface.
The remaining updates for the most part add support for additional
hardware in existing drivers or contain minor cleanups. Most of these
are for the Qualcomm Snapdragon platform.

- With commit 099f26f22f ("integrity: machine keyring CA
configuration") certificates may be loaded onto the IMA keyring,
directly or indirectly signed by keys on either the "builtin" or the
"machine" keyrings.
With the ability for the system/machine owner to sign the IMA policy
itself without needing to recompile the kernel, update the IMA
architecture specific policy rules to require the IMA policy itself
be signed.
[ As commit 099f26f22f was upstreamed in linux-6.4, updating the
IMA architecture specific policy now to require signed IMA policies
may break userspace expectations. ]

- Support partial SMT enablement.
So far the sysfs SMT control only allows to toggle between SMT on and
off. That's sufficient for x86 which usually has at max two threads
except for the Xeon PHI platform which has four threads per core.
Though PowerPC has up to 16 threads per core and so far it's only
possible to control the number of enabled threads per core via a
command line option. There is some way to control this at runtime, but
that lacks enforcement and the usability is awkward.
This update expands the sysfs interface and the core infrastructure to
accept numerical values so PowerPC can build SMT runtime control for
partial SMT enablement on top.
The core support has also been provided to the PowerPC maintainers who
added the PowerPC related changes on top.
- Minor cleanups and documentation updates.

Introduce the crash_hotplug attribute for memory and CPUs for use by
userspace. These attributes directly facilitate the udev rule for
managing userspace re-loading of the crash kernel upon hot un/plug
changes.
For memory, expose the crash_hotplug attribute to the
/sys/devices/system/memory directory. For example:
# udevadm info --attribute-walk /sys/devices/system/memory/memory81
looking at device '/devices/system/memory/memory81':
KERNEL=="memory81"
SUBSYSTEM=="memory"
DRIVER==""
ATTR{online}=="1"
ATTR{phys_device}=="0"
ATTR{phys_index}=="00000051"
ATTR{removable}=="1"
ATTR{state}=="online"
ATTR{valid_zones}=="Movable"
looking at parent device '/devices/system/memory':
KERNELS=="memory"
SUBSYSTEMS==""
DRIVERS==""
ATTRS{auto_online_blocks}=="offline"
ATTRS{block_size_bytes}=="8000000"
ATTRS{crash_hotplug}=="1"
For CPUs, expose the crash_hotplug attribute to the
/sys/devices/system/cpu directory. For example:
# udevadm info --attribute-walk /sys/devices/system/cpu/cpu0
looking at device '/devices/system/cpu/cpu0':
KERNEL=="cpu0"
SUBSYSTEM=="cpu"
DRIVER=="processor"
ATTR{crash_notes}=="277c38600"
ATTR{crash_notes_size}=="368"
ATTR{online}=="1"
looking at parent device '/devices/system/cpu':
KERNELS=="cpu"
SUBSYSTEMS==""
DRIVERS==""
ATTRS{crash_hotplug}=="1"
ATTRS{isolated}==""
ATTRS{kernel_max}=="8191"
ATTRS{nohz_full}==" (null)"
ATTRS{offline}=="4-7"
ATTRS{online}=="0-3"
ATTRS{possible}=="0-7"
ATTRS{present}=="0-3"
With these sysfs attributes in place, it is possible to efficiently
instruct the udev rule to skip crash kernel reloading for kernels
configured with crash hotplug support.
For example, the following is the proposed udev rule change for RHEL
system 98-kexec.rules (as the first lines of the rule file):
# The kernel updates the crash elfcorehdr for CPU and memory changes
SUBSYSTEM=="cpu", ATTRS{crash_hotplug}=="1", GOTO="kdump_reload_end"
SUBSYSTEM=="memory", ATTRS{crash_hotplug}=="1", GOTO="kdump_reload_end"
When examined in the context of 98-kexec.rules, the above rules test if
crash_hotplug is set, and if so, the userspace initiated
unload-then-reload of the crash kernel is skipped.
CPU and memory checks are separated in accordance with CONFIG_HOTPLUG_CPU
and CONFIG_MEMORY_HOTPLUG kernel config options. If an architecture
supports, for example, memory hotplug but not CPU hotplug, then the
/sys/devices/system/memory/crash_hotplug attribute file is present, but
the /sys/devices/system/cpu/crash_hotplug attribute file will NOT be
present. Thus the udev rule skips userspace processing of memory hot
un/plug events, but the udev rule will evaluate false for CPU events, thus
allowing userspace to process CPU hot un/plug events (ie the
unload-then-reload of the kdump capture kernel).

Commit b655892ffd ("leds: trigger: netdev: expose hw_control status
via sysfs") exposed to sysfs the flag that tells whether the LED trigger
is offloaded to hardware, under the name "hw_control", since that is the
name under which this setting is called in the code.
Everywhere else in kernel when some work that is normally done in
software can be made to be done by hardware instead, we use the word
"offloading" to describe this, e.g. "LED blinking is offloaded to
hardware".
Normally renaming sysfs entries is a no-go because of backwards
compatibility. But since this patch was not yet released in a stable
kernel, I think it is still possible to rename it, if there is
consensus.

Commit 273df864cf ("ima: Check against blacklisted hashes for files with
modsig") introduced an appraise_flag option for referencing the blacklist
keyring. Any matching binary found on this keyring fails signature
validation. This flag only works with module appended signatures.
An important part of a PKI infrastructure is to have the ability to do
revocation at a later time should a vulnerability be found. Expand the
revocation flag usage to all appraisal functions. The flag is now
enabled by default. Setting the flag with an IMA policy has been
deprecated. Without a revocation capability like this in place, only
authenticity can be maintained. With this change, integrity can now be
achieved with digital signature based IMA appraisal.

Add support to the /sys/devices/system/cpu/smt/control interface for
enabling a specified number of SMT threads per core, including partial
SMT states where not all threads are brought online.
The current interface accepts "on" and "off", to enable either 1 or all
SMT threads per core.
This commit allows writing an integer, between 1 and the number of SMT
threads supported by the machine. Writing 1 is a synonym for "off", 2 or
more enables SMT with the specified number of threads.
When reading the file, if all threads are online "on" is returned, to
avoid changing behaviour for existing users. If some other number of
threads is online then the integer value is returned.
Architectures like x86 only supporting 1 thread or all threads, should not
define CONFIG_SMT_NUM_THREADS_DYNAMIC. Architecture supporting partial SMT
states, like PowerPC, should define it.

When a grant entry is still in use by the remote domain, Linux must put
it on a deferred list. Normally, this list is very short, because
the PV network and block protocols expect the backend to unmap the grant
first. However, Qubes OS's GUI protocol is subject to the constraints
of the X Window System, and as such winds up with the frontend unmapping
the window first. As a result, the list can grow very large, resulting
in a massive memory leak and eventual VM freeze.
To partially solve this problem, make the number of entries that the VM
will attempt to free at each iteration tunable. The default is still
10, but it can be overridden via a module parameter.
This is Cc: stable because (when combined with appropriate userspace
changes) it fixes a severe performance and stability problem for Qubes
OS users.

This patch allows users to set up MIDI 1.0 ports more flexibly.
Namely, instead of the fixed mapping only from FB 0, now multiple
block definitions are applied to build up the MIDI 1.0 mapping.
The each block config has midi1_first_group and midi1_num_groups
attributes, and those specify which Groups are used for MIDI 1.0.
Those fields must be within the UMP Groups defined in the block
itself.

This patch adds the support of configfs to MIDI 2.0 function driver
for users to allow configuring the UMP Endpoint and Function Blocks
more flexibly. The configuration is in a tree form. The top-most
contains some card-level configurations. UMP Endpoints are defined in
subdirectories (ep.0, ep.1, etc) that contain Endpoint-specific
configurations such as ep_name, etc. And, UMP Function Blocks are
defined in the subdirectories (block.0, block.1, etc) under EP
subdirectory. As default, the driver creates a single UMP Endpoint
(ep.0) and a single Function Block (block.0) to work in a minimalistic
manner. User can modify those attributes freely to fit with the
demands.
When multiple Function Blocks are required, user can create another
directory as block.1, block.2, and so on (up to block.31). A block.*
directory can be deleted dynamically, too. A caveat is that the block
number has to be continuous.
Similarly, when multiple UMP Endpoints are required, user can create
another directory as ep.1, ep.2, up to ep.3.
Also, some driver behavior can be controlled in the card top-level
configs. e.g. you can pass process_ump=0 to disable the processing of
UMP Stream messages. This would be equivalent with the older MIDI 2.0
spec that doesn't support UMP v1.1 features.
The configfs interface checks upper- / lower-bound of input values,
and more sanity checks are performed at binding.
Attributes can't be changed any longer once when the instance is
linked to UDC.

There are devices (such as Murata IRS-D200 PIR proximity sensor) that
check the data signal with a running period. I.e. for a specified time,
they count the number of conditions that have occurred, and then signal
if that is more than a specified amount.
`IIO_EV_INFO_PERIOD` resets when the condition no longer is true and is
therefore not suitable for these devices. Add a new `iio_event_info`
`IIO_EV_INFO_RUNNING_PERIOD` that can be used as a running period. Also
add a new `IIO_EV_INFO_RUNNING_COUNT` that can be used to specify the
number of conditions that must occur during this running period.

Under some circumstances, firmware in the QAT devices could become
unresponsive. The Heartbeat feature provides a mechanism to detect
unresponsive devices.
The QAT FW periodically writes to memory a set of counters that allow
to detect the liveness of a device. This patch adds logic to enable
the reporting of those counters, analyze them and report if a device
is alive or not.
In particular this adds
(1) heartbeat enabling, reading and detection logic
(2) reporting of heartbeat status and configuration via debugfs
(3) documentation for the newly created sysfs entries
(4) configuration of FW settings related to heartbeat, e.g. tick period
(5) logic to convert time in ms (provided by the user) to clock ticks
This patch introduces a new folder in debugfs called heartbeat with the
following attributes:
- status
- queries_sent
- queries_failed
- config
All attributes except config are reading only. In particular:
- `status` file returns 0 when device is operational and -1 otherwise.
- `queries_sent` returns the total number of heartbeat queries sent.
- `queries_failed` returns the total number of heartbeat queries failed.
- `config` allows to adjust the frequency at which the firmware writes
counters to memory. This period is given in milliseconds and it is
fixed for GEN4 devices.

Gather Data Sampling (GDS) is a hardware vulnerability which allows
unprivileged speculative access to data which was previously stored in
vector registers.
Intel processors that support AVX2 and AVX512 have gather instructions
that fetch non-contiguous data elements from memory. On vulnerable
hardware, when a gather instruction is transiently executed and
encounters a fault, stale data from architectural or internal vector
registers may get transiently stored to the destination vector
register allowing an attacker to infer the stale data using typical
side channel techniques like cache timing attacks.
This mitigation is different from many earlier ones for two reasons.
First, it is enabled by default and a bit must be set to *DISABLE* it.
This is the opposite of normal mitigation polarity. This means GDS can
be mitigated simply by updating microcode and leaving the new control
bit alone.
Second, GDS has a "lock" bit. This lock bit is there because the
mitigation affects the hardware security features KeyLocker and SGX.
It needs to be enabled and *STAY* enabled for these features to be
mitigated against GDS.
The mitigation is enabled in the microcode by default. Disable it by
setting gather_data_sampling=off or by disabling all mitigations with
mitigations=off. The mitigation status can be checked by reading:

Merge tag 'cxl-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dan Williams:
"The highlights in terms of new functionality are support for the
standard CXL Performance Monitor definition that appeared in CXL 3.0,
support for device sanitization (wiping all data from a device),
secure-erase (re-keying encryption of user data), and support for
firmware update. The firmware update support is notable as it reuses
the simple sysfs_upload interface to just cat(1) a blob to a sysfs
file and pipe that to the device.
Additionally there are a substantial number of cleanups and
reorganizations to get ready for RCH error handling (RCH == Restricted
CXL Host == current shipping hardware generation / pre CXL-2.0
topologies) and type-2 (accelerator / vendor specific) devices.
For vendor specific devices they implement a subset of what the
generic type-3 (generic memory expander) driver expects. As a result
the rework decouples optional infrastructure from the core driver
context.
For RCH topologies, where the specification working group did not want
to confuse pre-CXL-aware operating systems, many of the standard
registers are hidden which makes support standard bus features like
AER (PCIe Advanced Error Reporting) difficult. The rework arranges for
the driver to help the PCI-AER core. Bjorn is on board with this
direction but a late regression disocvery means the completion of this
functionality needs to cook a bit longer, so it is code
reorganizations only for now.
Summary:
- Add infrastructure for supporting background commands along with
support for device sanitization and firmware update
- Introduce a CXL performance monitoring unit driver based on the
common definition in the specification.
- Land some preparatory cleanup and refactoring for the anticipated
arrival of CXL type-2 (accelerator devices) and CXL RCH (CXL-v1.1
topology) error handling.
- Rework CPU cache management with respect to region configuration

MSG_SPLICE_PAGES. Rework the handling of unexpected-end-of-file
to invoke an additional callback instead of trying to predict what
the right combination of MORE/NOTLAST flags is.
Remove the MSG_SENDPAGE_NOTLAST flag completely.
- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid.
- Enable socket busy polling with CONFIG_RT.
- Improve reliability and efficiency of reporting for ref_tracker.
- Auto-generate a user space C library for various Netlink families.
Protocols
---------
- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2].
- Use per-VMA locking for "page-flipping" TCP receive zerocopy.
- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags.
- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative.
- Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO).
- Avoid waking up applications using TLS sockets until we have
a full record.
- Allow using kernel memory for protocol ioctl callbacks, paving
the way to issuing ioctls over io_uring.
- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address.
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch.
- PPPoE: make number of hash bits configurable.
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig).
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge).
- Support matching on Connectivity Fault Management (CFM) packets.
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug.
- HSR: don't enable promiscuous mode if device offloads the proto.
- Support active scanning in IEEE 802.15.4.
- Continue work on Multi-Link Operation for WiFi 7.
BPF
---
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used,
or in fact passing the verifier at all for complex programs,
especially those using open-coded iterators.
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what
the output buffer *should* be, without writing anything.
- Accept dynptr memory as memory arguments passed to helpers.
- Add routing table ID to bpf_fib_lookup BPF helper.
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands.
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only).
- Show target_{obj,btf}_id in tracing link fdinfo.
- Addition of several new kfuncs (most of the names are self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter
---------
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value.
- Increase ip_vs_conn_tab_bits range for 64BIT builds.
- Allow updating size of a set.
- Improve NAT tuple selection when connection is closing.
Driver API
----------
- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out).
- Support configuring rate selection pins of SFP modules.
- Factor Clause 73 auto-negotiation code out of the drivers, provide
common helper routines.
- Add more fool-proof helpers for managing lifetime of MDIO devices
associated with the PCS layer.
- Allow drivers to report advanced statistics related to Time Aware
scheduler offload (taprio).
- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message.
- Split devlink instance and devlink port operations.

Add the first typical (non-sanitization) consumer of the new background
command infrastructure, firmware update. Given both firmware-update and
sanitization were developed in parallel from the common
background-command baseline, resolve some minor context conflicts.
The sysfs based firmware loader mechanism was created to easily allow
userspace to upload firmware images to FPGA cards. This also happens to
be pretty suitable to create a user-initiated but kernel-controlled
firmware update mechanism for CXL devices, using the CXL specified
mailbox commands.
Since firmware update commands can be long-running, and can be processed
in the background by the endpoint device, it is desirable to have the
ability to chunk the firmware transfer down to smaller pieces, so that
one operation does not monopolize the mailbox, locking out any other
long running background commands entirely - e.g. security commands like
'sanitize' or poison scanning operations.
The firmware loader mechanism allows a natural way to perform this
chunking, as after each mailbox command, that is restricted to the
maximum mailbox payload size, the cxl memdev driver relinquishes control
back to the fw_loader system and awaits the next chunk of data to
transfer. This opens opportunities for other background commands to
access the mailbox and send their own slices of background commands.
Add the necessary helpers and state tracking to be able to perform the
'Get FW Info', 'Transfer FW', and 'Activate FW' mailbox commands as
described in the CXL spec. Wire these up to the firmware loader
callbacks, and register with that system to create the memX/firmware/
sysfs ABI.

Implement support for the non-pmem exclusive secure erase, per
CXL specs. Create a write-only 'security/erase' sysfs file to
perform the requested operation.
As with the sanitation this requires the device being offline
and thus no active HPA-DPA decoding.
The expectation is that userspace can use it such as:
cxl disable-memdev memX
echo 1 > /sys/bus/cxl/devices/memX/security/erase
cxl enable-memdev memX

Implement support for CXL 3.0 8.2.9.8.5.1 Sanitize. This is done by
adding a security/sanitize' memdev sysfs file to trigger the operation
and extend the status file to make it poll(2)-capable for completion.
Unlike all other background commands, this is the only operation that
is special and monopolizes the device for long periods of time.
In addition to the traditional pmem security requirements, all regions
must also be offline in order to perform the operation. This permits
avoiding explicit global CPU cache management, relying instead on the
implict cache management when a region transitions between
CXL_CONFIG_ACTIVE and CXL_CONFIG_COMMIT.
The expectation is that userspace can use it such as:
cxl disable-memdev memX
echo 1 > /sys/bus/cxl/devices/memX/security/sanitize
cxl wait-sanitize memX
cxl enable-memdev memX

Architecture-specific documentation is being moved into Documentation/arch/
as a way of cleaning up the top-level documentation directory and making
the docs hierarchy more closely match the source hierarchy. Move
Documentation/arm64 into arch/ (along with the Chinese equvalent
translations) and fix up documentation references.

The PTT can only filter the traced TLP headers by the Root Ports or the
Requester ID of the Endpoint, which are located on the same PCIe core of
the PTT device. The filter value used is derived from the BDF number of
the supported Root Port or the Endpoint. It's not friendly enough for the
users since it requires the user to be familiar enough with the platform
and calculate the filter value manually.
This patch export the available filters through sysfs. Each available
filters is presented as an individual file with the name of the BDF
number of the related PCIe device. The files are created under
$(PTT PMU dir)/available_root_port_filters and
$(PTT PMU dir)/available_requester_filters respectively. The filter
value can be known by reading the related file.
Then the users can easily know the available filters for trace and get
the filter values without calculating.

There are three flags that control Write Booster Feature:
1. WB ON/OFF
2. WB Hibern Flush ON/OFF (implicitly)
3. WB Flush ON/OFF (explicit)
In the case of "Hibern Flush", one of the conditions for flush WB buffer is
that avail_wb_buff < wb_flush_threshold.
As we know, different users have different requirements for power
consumption and performance. Therefore, we need the ability to manually set
wb_flush_threshold, so that users can easily and flexibly adjust the
wb_flush_threshold value, thereby achieving a balance between power
consumption and performance.
So the sysfs attribute that controls this is necessary.
wb_flush_threshold represents the threshold for flushing WB buffer, whose
value expressed in unit of 10% granularity, such as '1' representing 10%,
'2' representing 20%, and so on.
