The big change in this release is that Matti Vaittinen has factored out
the linear ranges support into a separate library in lib/ since it is
also useful for at least the power subsystem (and most likely others
too), it helps subsystems which need to map register values into more
useful real world values do so with minimal per-driver code.
- Factoring out of the linear ranges support into a library in lib/
from Matti Vaittinen.
- Trace points for bypass mode.
- Use the consumer name in debugfs to make it easier to understand.
- New drivers for Maxim MAX77826 and MAX8998.

This has been a very active release for the DesignWare driver in
particular - after a long period of inactivity we have had a lot of
people actively working on it for unrelated reasons this cycle with some
of that work still not landed. Otherwise it's been fairly quiet for the
subsystem. Highlights include:
- Lots of performance improvements and fixes for the DesignWare driver
from Serge Semin, Andy Shevchenko, Wan Ahmad Zainie, Clement Leger,
Dinh Nguyen and Jarkko Nikula.
- Support for octal mode transfers in spidev.
- Slave mode support for the Rockchip drivers.
- Support for AMD controllers, Broadcom mspi and Raspberry Pi 4,
and Intel Elkhart Lake.

KVM/arm64 updates for Linux 5.8:
- Move the arch-specific code into arch/arm64/kvm
- Start the post-32bit cleanup
- Cherry-pick a few non-invasive pre-NV patches
Add support for Hyper-V synthetic debugger (syndbg) interface.
The syndbg interface is using MSRs to emulate a way to send/recv packets
data.
The debug transport dll (kdvm/kdnet) will identify if Hyper-V is enabled
and if it supports the synthetic debugger interface it will attempt to
use it, instead of trying to initialize a network adapter.

Add new field to hold preemption timer expiration deadline
appended to struct kvm_vmx_nested_state_hdr. This is to prevent
the first VM-Enter after migration from incorrectly restarting the timer
with the full timer value instead of partially decayed timer value.
KVM_SET_NESTED_STATE restarts timer using migrated state regardless
of whether L1 sets VM_EXIT_SAVE_VMX_PREEMPTION_TIMER.

The problem the patch is trying to address is the fact that 'struct
kvm_hyperv_exit' has different layout on when compiling in 32 and 64 bit
modes.
In 64-bit mode the default alignment boundary is 64 bits thus
forcing extra gaps after 'type' and 'msr' but in 32-bit mode the
boundary is at 32 bits thus no extra gaps.
This is an issue as even when the kernel is 64 bit, the userspace using
the interface can be both 32 and 64 bit but the same 32 bit userspace has
to work with 32 bit kernel.
The issue is fixed by forcing the 64 bit layout, this leads to ABI
change for 32 bit builds and while we are obviously breaking '32 bit
userspace with 32 bit kernel' case, we're fixing the '32 bit userspace
with 64 bit kernel' one.
As the interface has no (known) users and 32 bit KVM is rather baroque
nowadays, this seems like a reasonable decision.

If two page ready notifications happen back to back the second one is not
delivered and the only mechanism we currently have is
kvm_check_async_pf_completion() check in vcpu_run() loop. The check will
only be performed with the next vmexit when it happens and in some cases
it may take a while. With interrupt based page ready notification delivery
the situation is even worse: unlike exceptions, interrupts are not handled
immediately so we must check if the slot is empty. This is slow and
unnecessary. Introduce dedicated MSR_KVM_ASYNC_PF_ACK MSR to communicate
the fact that the slot is free and host should check its notification
queue. Mandate using it for interrupt based 'page ready' APF event
delivery.
As kvm_check_async_pf_completion() is going away from vcpu_run() we need
a way to communicate the fact that vcpu->async_pf.done queue has
transitioned from empty to non-empty state. Introduce
kvm_arch_async_page_present_queued() and KVM_REQ_APF_READY to do the job.

Concerns were expressed around APF delivery via synthetic #PF exception as
in some cases such delivery may collide with real page fault. For 'page
ready' notifications we can easily switch to using an interrupt instead.
Introduce new MSR_KVM_ASYNC_PF_INT mechanism and deprecate the legacy one.
One notable difference between the two mechanisms is that interrupt may not
get handled immediately so whenever we would like to deliver next event
(regardless of its type) we must be sure the guest had read and cleared
previous event in the slot.
While on it, get rid on 'type 1/type 2' names for APF events in the
documentation as they are causing confusion. Use 'page not present'
and 'page ready' everywhere instead.

This introduces mtdpstore, which is similar to mtdoops but more
powerful. It uses pstore/blk, and aims to store panic and oops logs to
a flash partition, where pstore can later read back and present as files
in the mounted pstore filesystem.
To make mtdpstore work, the "blkdev" of pstore/blk should be set
as MTD device name or MTD device number. For more details, see
Documentation/admin-guide/pstore-blk.rst
This solves a number of issues:
- Work duplication: both of pstore and mtdoops do the same job storing
panic/oops log. They have very similar logic, registering to kmsg
dumper and storing logs to several chunks one by one.
- Layer violations: drivers should provides methods instead of polices.
MTD should provide read/write/erase operations, and allow a higher
level drivers to provide the chunk management, kmsg dump
configuration, etc.
- Missing features: pstore provides many additional features, including
presenting the logs as files, logging dump time and count, and
supporting other frontends like pmsg, console, etc.

Yes, staying withing 80 columns is certainly still _preferred_. But
it's not the hard limit that the checkpatch warnings imply, and other
concerns can most certainly dominate.
Increase the default limit to 100 characters. Not because 100
characters is some hard limit either, but that's certainly a "what are
you doing" kind of value and less likely to be about the occasional
slightly longer lines.
Miscellanea:
- to avoid unnecessary whitespace changes in files, checkpatch will no
longer emit a warning about line length when scanning files unless
--strict is also used
- Add a bit to coding-style about alignment to open parenthesis

After being gained by the CCU PLLs the signals must be transformed to
be suitable for the clock-consumers. This is done by a set of dividers
embedded into the CCU. A first block of dividers is used to create
reference clocks for AXI-bus of high-speed peripheral IP-cores of the
chip. The second block dividers alter the PLLs output signals to be then
consumed by SoC peripheral devices. Both block DT nodes are ordinary
clock-providers with standard set of properties supported. But in addition
to that each clock provider can be used to reset the corresponding clock
domain. This makes the AXI-bus and System Devices CCU DT nodes to be also
reset-providers.

firstly handled by the embedded into CCU PLLs. So the corresponding

the new max_reason setting has precedence.
For struct ramoops_platform_data, the "dump_oops" member is entirely

Additionally remove the "reason" filter logic from ramoops_pstore_write(),
as that is not specifically needed anymore, though technically
this is a change in behavior for any ramoops users also setting the
printk.always_kmsg_dump boot param, which will cause ramoops to behave as

Provide for a more generic solution by allowing specification of an

implements support for this pin for any 8250 driver. The binding is

In certain designs, it is possible to add a battery on a populated i2c
bus without an sbs compliant charger. In that case, the battery will
unnecessarily and sometimes undesirably master the bus trying to write
info in the charger.
It is observed in many occasion that these battery "broadcasts" are even
corrupting other ongoing master to slave communication. I.e. the
multi-master support in the battery is inadequate.
Thankfully, the CHARGER_MODE bit allows designers to disable that SBS
battery behaviour.
This needs to be done once when the battery is first seen on the bus.

Baikal-T1 SoC provides an embedded process, voltage and temperature
sensor to monitor an internal SoC environment (chip temperature, supply
voltage and process monitor) and on time detect critical situations,
which may cause the system instability and even damages. The IP-block
is based on the Analog Bits PVT sensor, but is equipped with a
dedicated control wrapper, which provides a MMIO registers-based access
to the sensor core functionality (APB3-bus based) and exposes an
additional functions like thresholds/data ready interrupts, its status
and masks, measurements timeout. All of these is used to create a hwmon
driver being added to the kernel by this commit.
The driver implements support for the hardware monitoring capabilities
of Baikal-T1 process, voltage and temperature sensors. PVT IP-core
consists of one temperature and four voltage sensors, each of which is
implemented as a dedicated hwmon channel config.
The driver can optionally provide the hwmon alarms for each sensor the
PVT controller supports. The alarms functionality is made compile-time
configurable due to the hardware interface implementation peculiarity,
which is connected with an ability to convert data from only one sensor
at a time. Additional limitation is that the controller performs the
thresholds checking synchronously with the data conversion procedure.
Due to these limitations in order to have the hwmon alarms
automatically detected the driver code must switch from one sensor to
another, read converted data and manually check the threshold status
bits. Depending on the measurements timeout settings this design may
cause additional burden on the system performance. By default if the
alarms kernel config is disabled the data conversion is performed by
the driver on demand when read operation is requested via corresponding
_input-file.

Baikal-T1 SoC is equipped with an embedded process, voltage and
temperature sensor to monitor the chip internal environment like
temperature, supply voltage and transistors performance.
This bindings describes the external Baikal-T1 PVT control interfaces
like MMIO registers space, interrupt request number and clocks source.
These are then used by the corresponding hwmon device driver to
implement the sysfs files-based access to the sensors functionality.

There is a single register provided by the SoC system controller,
which can be used to tune the L2-cache RAM up. It only provides a way
to change the L2-RAM access latencies. So aside from "be,bt1-l2-ctl"
compatible string the device node can be optionally equipped with the
properties of Tag/Data/WS latencies.

Currently, the root cgroup does not have a cpu.stat file. Add one which
is consistent with /proc/stat to capture global cpu statistics that
might not fall under cgroup accounting.
We haven't done this in the past because the data are already presented
in /proc/stat and we didn't want to add overhead from collecting root
cgroup stats when cgroups are configured, but no cgroups have been
created.
By keeping the data consistent with /proc/stat, I think we avoid the
first problem, while improving the usability of cgroups stats.
We avoid the second problem by computing the contents of cpu.stat from
existing data collected for /proc/stat anyway.

[arnd: This is a patch series from Serge Semin to add a few drivers
that don't have any other subsystem maintainer tree to go through,
so I'm picking them up through the soc tree, full series description
from the mailing list below]
Baikal-T1 SoC CPU is based on two MIPS Warrior P5600 cores. Their main
memory Non-Coherent IO interface is connected to the OCP2AXI bridge,
which in turn is then connected to the DW AMBA 3 AXI Interconnect (so
called Main Interconnect) with nine masters and four slaves ports. Main
Interconnect is responsible for the AXI-bus traffic arbitration (QoS)
and its routing from one component to another. In addition there is
a Errors Handler Block (EHB) accesible by means of the Baikal-T1 SoC
System Controller responsible to detect AXI protocol errors and device
not responding situations built on top the interconnect. Baikal-T1 AXI-bus
driver included in this patchset will be responsible for working with that
functionality, though currently it doesn't support QoS tuning. Instead
it's capable of detecting the error events, reporting an info about
them to the system log, injecting artificial errors to test the driver
functionality. Since AXI Interconnect doesn't provide a way to find
out which devices are connected to it, so its DT node is supposed to
be compatible with "simple-bus" driver, while sub-nodes shall represent
the masters attached to the bus.
One of the AXI Interconnect slaves is an AXI-APB bridge used to access the
Baikal-T1 SoC subsystems CSRs. MMIO request from CPU and DMAC masters are
routed there if they are detected to be within [0x08000000 0x1FFFFFFF]
range of the physical memory. In case if an attempted APB transaction
stays with no response for a pre-defined time it will be detected by
the APB-bus Errors Handler Block (EHB), which will raise an interrupt,
then the bus gets freed for a next operation. The APB-bus driver provides
the interrupt handler to detect the erroneous address, update an errors
counter and prints an error message about the faulty address. The counter
and the APB-bus operations timeout can be accessed via corresponding sysfs
nodes. A dedicated sysfs-node can be also used to artificially cause the
bus errors described above. Since APB-bus is a platform bus, it doesn't
provide a way to detect slave devices connected to it, so similarly to
the AXI-bus it's also supposed to be compatible with "simple-bus" driver.
Aside from PCIe/SATA/DDR/I2C/EHB/CPU/reboot specific settings the
Baikal-T1 System Controller provides a MIPS P5600 CM2 L2-cache tuning
block. It is responsible for the setting up the Tag/Data/WS L2-to-RAM
latencies. The last small patch in this patchset provides a driver and
DT-schema-based binding for the described device. So that the latencies
can be tuned up by means of dedicated DT properties and sysfs nodes.
This patchset is rebased and tested on the mainline Linux kernel
5.7-rc4.
Changelog v2 (AXI/APB bus):
- Assign dual GPL/BSD licenses to the bindings.
- Use single lined copyright headers in the bindings.
- Replace "additionalProperties: false" property with
"unevaluatedProperties: false" in the bindings.
- Don't use a multi-arg clock phandle reference in DT binding examples.
Thus remove includes from there.
- Fix some commit message and Kconfig help text spelling.
- Move drivers from soc to the bus subsystem.
- Convert a simple EHB drivers to the Baikal-T1 AXI and APB bus ones.
- Convert APB bus driver to using regmap MMIO API.
- Use syscon regmap to access the AXI-bus erroneous address.
- Add reset line support.
- Add Main Interconnect clock support to the AXI-bus driver.
- Remove probe-status info string printout.
- Discard of_match_ptr() macro utilization.
- Don't print error-message if no platform IRQ found. Just return an
error.
- Use generic FIELD_{GET,PREP} macros instead of handwritten ones in the
AXI-bus driver.
Changelog v2 (l2 driver):
- Fix some commit message and Kconfig help text spelling.
- Move the driver to the memory subsystem.
- Assign dual GPL/BSD license to the DT binding.
- Use single lined copyright header in the binding.
- Discard reg property and syscon compatible string.
- Move "allOf" restrictions to the root level of the properties.
- The DT node is supposed to be a child of the Baikal-T1 system
controller node. So regmap will be fetched from there.
- Use generic FIELD_{GET,PREP} macro.
- Remove probe-status info string printout.
- Since the driver depends on the OF config we can remove of_match_ptr()
macro utilization.
Changelog v3:
- Combine l2 and AXI/APB bus patches in a single patchset.
- Retrieve AXI-bus QoS registers by resource name "qos".
- Discard CONFIG_OF dependency since there is none at compile-time.
- Add syscon EHB registers range to the AXI-bus reg property as optional
entry.
- Fix invalid of_property_read_u32() return value test in the l2-ctl
driver.
- Get the reg property back into the l2-ctl DT bindings even though the
driver is using the parental syscon regmap.
- The l2-ctl DT schema will live separately from the system controller,
but the corresponding sub-node of the later DT schema will $ref this
one.
- Set non-default latencies in the l2-ctl DT example.

preempt_disable() and local_irq_disable/save() are in principle per CPU big
kernel locks. This has several downsides:
- The protection scope is unknown
- Violation of protection rules is hard to detect by instrumentation
- For PREEMPT_RT such sections, unless in low level critical code, can
violate the preemptability constraints.
To address this PREEMPT_RT introduced the concept of local_locks which are
strictly per CPU.
The lock operations map to preempt_disable(), local_irq_disable/save() and
the enabling counterparts on non RT enabled kernels.
If lockdep is enabled local locks gain a lock map which tracks the usage
context. This will catch cases where an area is protected by
preempt_disable() but the access also happens from interrupt context. local
locks have identified quite a few such issues over the years, the most
recent example is:
b7d5dc2107 ("random: add a spinlock_t to struct batched_entropy")
Aside of the lockdep coverage this also improves code readability as it
precisely annotates the protection scope.
PREEMPT_RT substitutes these local locks with 'sleeping' spinlocks to
protect such sections while maintaining preemtability and CPU locality.
local locks can replace:
- preempt_enable()/disable() pairs
- local_irq_disable/enable() pairs
- local_irq_save/restore() pairs
They are also used to replace code which implicitly disables preemption
like:
- get_cpu()/put_cpu()
- get_cpu_var()/put_cpu_var()
with PREEMPT_RT friendly constructs.

When an EFI variable is reading from:
/sys/firmware/efi/efivars
(for example using "hexdump"), the first 4 bytes of the
output are not the real EFI variable data, but the variable
attributes (in little-endian format).

This is a first pass at updating the basic documentation on
Linux Security Modules (LSM), which is frighteningly out of date.
Remove untrue statements about the LSM framework. Replace them
with true statements where it is convenient to do so. This is
the beginnig of a larger effort to bring the LSM documentation
up to date.

and documentation fixes for the RPMH driver. It adds a debugfs mechanism
for inspecting Command DB. Socinfo got the "soc_id" attribute defines
and definitions for a various variants of MSM8939.
RPMH, RPMPD and RPMHPD where made possible to build as modules, but RPMH
had to be reverted due to a compilation issue when tracing is enabled.
RPMHPD gained power-domains for the SM8250 voltage corners.
The SCM driver gained fixes for two build warnings and the SMP2P had an
unnecessary error print removed.

This driver adds support for Dynamic Platform and Thermal Framework
battery participant device support.
These attributes are presented via sysfs interface under the platform
device for the battery participant:
$ls /sys/bus/platform/devices/INT3532:00/dptf_battery
current_discharge_capbility_ma
max_platform_power_mw
no_load_voltage_mv
high_freq_impedance_mohm
max_steady_state_power_mw
Refer to the documentation at
Documentation/ABI/testing/sysfs-platform-dptf
for details.
Here the implementation reuses existing dptf-power.c as the motivation and
processing is same. It also shares one ACPI method. Here this change is
using participant type, "PTYP" method to identify and do different
processing. By using participant type, create/delete either "dptf_power"
or "dptf_battery" attribute group and send notifications.
The particpant type for for the battery participant is 0x0C.
ACPI methods description:
PMAX (Intel(R) Dynamic Tuning Platform Max Power Supplied by Battery):
This object evaluates to the maximum platform power that can be supported
by the battery in milli watts.
PBSS (Intel(R) Dynamic Tuning Power Battery Steady State):
This object returns the max sustained power for battery in milli watts.
RBHF (Intel(R) Dynamic Tuning High Frequency Impedance):
This object returns high frequency impedance value that can be obtained
from battery fuel gauge.
VBNL (Intel(R) Dynamic Tuning No-Load Voltage)
This object returns battery instantaneous no-load voltage that can be
obtained from battery fuel gauge in milli volts
CMPP (Intel(R) Dynamic Tuning Current Discharge Capability)
This object returns battery discharge current capability obtained from
battery fuel gauge milli amps.
Notifications:
0x80: PMAX change. Used to notify Intel(R)Dynamic Tuning Battery
participant driver when the PMAX has changed by 250mw.
0x83: PBSS change. Used to notify Intel(R) Dynamic Tuning Battery
participant driver when the power source has changed.
0x85: RBHF change. Used to notify Intel(R)Dynamic Tuning Battery
participant driver when the RBHF has changed over a threshold by
5mOhm.

Add two additional attributes to the existing power participant driver:
rest_of_platform_power_mw: (RO) Shows the rest of worst case platform
power in mW outside of S0C. This will help in power distribution to SoC
and rest of the system. For example on a test system, this value is 2.5W
with a 15W TDP SoC. Based on the adapter rating (adapter_rating_mw), user
space software can decide on proper power allocation to SoC to improve
short term performance via powercap/RAPL interface.
prochot_confirm: (WO) Confirm EC about a prochot notification.
Also userspace is notified via sysfs_notify(), whenever power source or
rest of the platform power is changed. So user space can use poll()
system call on those attributes.
The ACPI methods used in this patch are as follows:
PROP
This object evaluates to the rest of worst case platform power in mW.
Bits:
23:0 Worst case rest of platform power in mW.
PBOK
PBOK is a method designed to provide a mechanism for OSPM to change power
setting before EC can de-assert a PROCHOT from a device. The EC may
receive several PROCHOTs, so it has a sequence number attached to PSRC
(read via existing attribute "platform_power_source"). Once OSPM takes
action for a PSRC change notification, it can call PBOK method to confirm
with the sequence number.
Bits:
3:0 Power Delivery State Change Sequence number
30 Reserved
31 0 – Not OK to de-assert PROCHOT
1 – OK to de-assert PROCHOT
PSRC (Platform Power Source): Not new in this patch but for
documentation for new bits
This object evaluates to an integer that represents the system power
source as well as the power delivery state change sequence number.
Bits:
3:0 The current power source as an integer for AC, DC, USB, Wireless.
0 = DC, 1 = AC, 2 = USB, 3 = Wireless Charging
7:4 Power Delivery State Change Sequence Number. Default value is 0
Notifications:
0x81: (Power State Change) Used to notify when the power source has
changed.
0x84: (PROP change) Used to notify when the platform rest of power has
changed.

pull-request: bpf-next 2020-05-23
The following pull-request contains BPF updates for your *net-next* tree.
We've added 50 non-merge commits during the last 8 day(s) which contain
a total of 109 files changed, 2776 insertions(+), 2887 deletions(-).
The main changes are:
1) Add a new AF_XDP buffer allocation API to the core in order to help
lowering the bar for drivers adopting AF_XDP support. i40e, ice, ixgbe
as well as mlx5 have been moved over to the new API and also gained a
small improvement in performance, from Björn Töpel and Magnus Karlsson.
2) Add getpeername()/getsockname() attach types for BPF sock_addr programs
in order to allow for e.g. reverse translation of load-balancer backend
to service address/port tuple from a connected peer, from Daniel Borkmann.
3) Improve the BPF verifier is_branch_taken() logic to evaluate pointers
being non-NULL, e.g. if after an initial test another non-NULL test on
that pointer follows in a given path, then it can be pruned right away,
from John Fastabend.
4) Larger rework of BPF sockmap selftests to make output easier to understand
and to reduce overall runtime as well as adding new BPF kTLS selftests
that run in combination with sockmap, also from John Fastabend.
5) Batch of misc updates to BPF selftests including fixing up test_align
to match verifier output again and moving it under test_progs, allowing
bpf_iter selftest to compile on machines with older vmlinux.h, and
updating config options for lirc and v6 segment routing helpers, from
Stanislav Fomichev, Andrii Nakryiko and Alan Maguire.
6) Conversion of BPF tracing samples outdated internal BPF loader to use
libbpf API instead, from Daniel T. Lee.
7) Follow-up to BPF kernel test infrastructure in order to fix a flake in
the XDP selftests, from Jesper Dangaard Brouer.
8) Minor improvements to libbpf's internal hashmap implementation, from
Ian Rogers.

Modern device tree bindings are supposed to be created as YAML-files
in accordance with DT schema. This commit replaces Synopsys DW Timer
legacy bare text binding with YAML file. As before the binding file
states that the corresponding dts node is supposed to be compatible
with generic DW APB Timer indicated by the "snps,dw-apb-timer"
compatible string and to provide a mandatory registers memory range,
one timer interrupt, either reference clock source or a fixed clock
rate value. It may also have an optional APB bus reference clock
phandle specified.

As part of moving the thermal bindings to YAML, split it up into 3
bindings: thermal sensors, cooling devices and thermal zones.
The thermal-zone binding is a software abstraction to capture the
properties of each zone - how often they should be checked, the
temperature thresholds (trips) at which mitigation actions need to be
taken and the level of mitigation needed at those thresholds.

As part of moving the thermal bindings to YAML, split it up into 3
bindings: thermal sensors, cooling devices and thermal zones.
The property #cooling-cells is required in each device that acts as a
cooling device - whether active or passive. So any device that can
throttle its performance to passively reduce heat dissipation (e.g.
CPUs, GPUs) and any device that can actively dissipate heat at different
levels (e.g. fans) will contain this property.

Merge tag 'v5.8-rockchip-dts64-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into arm/dt
New soc variant the rk3326 which is essentially a px30 with only one
display controller and a new board using it, the Odroid Advance Go.
sdcard regulator for the rockpro64 and a lot of devicetree fixes
making the dt-binding check a lot happier.

Changing base clock frequency directly impacts TSC Hz but not CPUID.16h
value. An overclocked CPU supporting CPUID.16h and with partial CPUID.15h
support will set TSC KHZ according to "best guess" given by CPUID.16h
relying on tsc_refine_calibration_work to give better numbers later.
tsc_refine_calibration_work will refuse to do its work when the outcome is
off the early TSC KHZ value by more than 1% which is certain to happen on
an overclocked system.
Fix this by adding a tsc_early_khz command line parameter that makes the
kernel skip early TSC calibration and use the given value instead.
This allows the user to provide the expected TSC frequency that is closer
to reality than the one reported by the hardware, enabling
tsc_refine_calibration_work to do meaningful error checking.
[ tglx: Made the variable __initdata as it's only used on init and
removed the error checking in the argument parser because
kstrto*() only stores to the variable if the string is valid ]

For SDM845 this defines the IPA network accelerator and the CCI camera
control bus, it defines the required UFS reset and adds WiFi for the
Lenovo Yoga C630 and defines GPIO pin names and adds OV8856 and OC7251
camera nodes for DB845c.
For SC7180 it adds GPU support, defines the modem remoteproc, adds the
IPA network accelerator, Coresight and ETM support, adds cpuidle low
power states and updates the CPUs' compatible.
For SM8250 it adds regulators from the PM8150, PM8150L and PM8009 and
adds voltage corners, it defines the nodes for UFS PHY and controller
and finally corrects a typo in the PDC node to make SPMI functional.
For MSM8916 I2C1 and I2C5 are defined, a node for the CCI camera control
interface bus is added and Coresight is disabled by default to match
some product configurations. The Samsung A3U gained display support and
Samsung A5U gained touchscreen support.
MSM8996 now property describes the power supply chain for the GPU, the
CCI camera control interface bus is added and the DB820c has the
regulators of the secondary PMIC defined.
For QCS404 USB PHYs and controllers are defined and wired up for the

Userspace libraries, e.g. glibc's dprintf(), perform a SEEK_CUR operation
over any file descriptor requested to make sure the current position isn't
pointing to junk due to previous manipulation of that same fd. And whenever
that fd doesn't have support for such operation, the userspace code expects
-ESPIPE to be returned.
However, when the fd in question references the /dev/kmsg interface, the
current kernel code state returns -EINVAL instead, causing an unexpected
behavior in userspace: in the case of glibc, when -ESPIPE is returned it
gets ignored and the call completes successfully, while returning -EINVAL
forces dprintf to fail without performing any action over that fd:
if (_IO_SEEKOFF (fp, (off64_t)0, _IO_seek_cur, _IOS_INPUT|_IOS_OUTPUT) ==
_IO_pos_BAD && errno != ESPIPE)
return NULL;
With this patch we make sure to return the correct value when SEEK_CUR is
requested over kmsg and also add some kernel doc information to formalize
this behavior.

Implement handling for metadata version 2. The new metadata adds a
label and UUID for the device mapper device, and additional UUID for
the underlying block devices.
It also allows for an additional regular drive to be used for
emulating random access zones. The emulated zones will be placed
logically in front of the zones from the zoned block device, causing
the superblocks and metadata to be stored on that device.
The first zone of the original zoned device will be used to hold
another, tertiary copy of the metadata; this copy carries a generation
number of 0 and is never updated; it's just used for identification.

Add maintainer entries to a few ROHM devices and Linear Ranges
Linear Ranges helpers were refactored out of regulator core to lib so
that other drivers could utilize them too. (I guess power/supply drivers
and possibly clk drivers can benefit from them). As regulators is
currently the main user it makes sense the changes to linear_ranges go
through Mark's tree.
During past two years few ROHM PMIC drivers have been added to
mainstream. They deserve a supporter from ROHM side too :)

Expose MIPI DisCo Slave properties in sysfs.
For Slave properties and Data Port 0, the attributes are managed with
simple devm_ support.
A Slave Device may have more than one Data Port (DPN), and each Data
Port can be sink or source. The attributes are created dynamically
using pre-canned macros, but still use devm_ with a name attribute
group to avoid creating kobjects - as requested by GregKH. In the
_show function, we use container_of() to retrieve port number and
direction required to extract the information.
Audio modes are not supported for now. Depending on the discussions

By providing the default values configured into the kernel via sysfs, it

The gen_kselftest_tar.sh always packages *all* selftests and doesn't
pass along any variables to `make install` to influence what should be
built. This can result in an early error on the command line ("Unknown
tarball format TARGETS=XXX"), or unexpected test failures as the
tarball contains tests people wanted to skip on purpose.
Since the makefile already contains all the logic, we can add a target
for packaging. Keep the default .gz target the script uses, and actually
extend the supported formats by using tar's autodetection.
To not break current workflows, keep the gen_kselftest_tar.sh script as
it is, with an added suggestion to use the makefile target instead.

The eMMC inline crypto standard will only specify 32 DUN bits (a.k.a. IV
bits), unlike UFS's 64. IV_INO_LBLK_64 is therefore not applicable, but
an encryption format which uses one key per policy and permits the
moving of encrypted file contents (as f2fs's garbage collector requires)
is still desirable.
To support such hardware, add a new encryption format IV_INO_LBLK_32
that makes the best use of the 32 bits: the IV is set to
'SipHash-2-4(inode_number) + file_logical_block_number mod 2^32', where
the SipHash key is derived from the fscrypt master key. We hash only
the inode number and not also the block number, because we need to
maintain contiguity of DUNs to merge bios.
Unlike with IV_INO_LBLK_64, with this format IV reuse is possible; this
is unavoidable given the size of the DUN. This means this format should
only be used where the requirements of the first paragraph apply.
However, the hash spreads out the IVs in the whole usable range, and the
use of a keyed hash makes it difficult for an attacker to determine
which files use which IVs.
Besides the above differences, this flag works like IV_INO_LBLK_64 in
that on ext4 it is only allowed if the stable_inodes feature has been
enabled to prevent inode numbers and the filesystem UUID from changing.

Add a key/keyring change notification facility whereby notifications about
changes in key and keyring content and attributes can be received.
Firstly, an event queue needs to be created:
pipe2(fds, O_NOTIFICATION_PIPE);
ioctl(fds[1], IOC_WATCH_QUEUE_SET_SIZE, 256);
then a notification can be set up to report notifications via that queue:
struct watch_notification_filter filter = {
.nr_filters = 1,
.filters = {
[0] = {
.type = WATCH_TYPE_KEY_NOTIFY,
.subtype_filter[0] = UINT_MAX,
},
},
};
ioctl(fds[1], IOC_WATCH_QUEUE_SET_FILTER, &filter);
keyctl_watch_key(KEY_SPEC_SESSION_KEYRING, fds[1], 0x01);
After that, records will be placed into the queue when events occur in
which keys are changed in some way. Records are of the following format:
struct key_notification {
struct watch_notification watch;
__u32 key_id;
__u32 aux;
} *n;
Where:
n->watch.type will be WATCH_TYPE_KEY_NOTIFY.
n->watch.subtype will indicate the type of event, such as
NOTIFY_KEY_REVOKED.
n->watch.info & WATCH_INFO_LENGTH will indicate the length of the
record.
n->watch.info & WATCH_INFO_ID will be the second argument to
keyctl_watch_key(), shifted.
n->key will be the ID of the affected key.
n->aux will hold subtype-dependent information, such as the key
being linked into the keyring specified by n->key in the case of
NOTIFY_KEY_LINKED.
Note that it is permissible for event records to be of variable length -
or, at least, the length may be dependent on the subtype. Note also that
the queue can be shared between multiple notifications of various types.

Make it possible to have a general notification queue built on top of a
standard pipe. Notifications are 'spliced' into the pipe and then read
out. splice(), vmsplice() and sendfile() are forbidden on pipes used for
notifications as post_one_notification() cannot take pipe->mutex. This
means that notifications could be posted in between individual pipe
buffers, making iov_iter_revert() difficult to effect.
The way the notification queue is used is:
(1) An application opens a pipe with a special flag and indicates the
number of messages it wishes to be able to queue at once (this can
only be set once):
pipe2(fds, O_NOTIFICATION_PIPE);
ioctl(fds[0], IOC_WATCH_QUEUE_SET_SIZE, queue_depth);
(2) The application then uses poll() and read() as normal to extract data
from the pipe. read() will return multiple notifications if the
buffer is big enough, but it will not split a notification across
buffers - rather it will return a short read or EMSGSIZE.
Notification messages include a length in the header so that the
caller can split them up.
Each message has a header that describes it:
struct watch_notification {
__u32 type:24;
__u32 subtype:8;
__u32 info;
};
The type indicates the source (eg. mount tree changes, superblock events,
keyring changes, block layer events) and the subtype indicates the event
type (eg. mount, unmount; EIO, EDQUOT; link, unlink). The info field
indicates a number of things, including the entry length, an ID assigned to
a watchpoint contributing to this buffer and type-specific flags.
Supplementary data, such as the key ID that generated an event, can be
attached in additional slots. The maximum message size is 127 bytes.
Messages may not be padded or aligned, so there is no guarantee, for
example, that the notification type will be on a 4-byte bounary.

In Gaudi there is a feature of clock gating certain engines.
Therefore, add this property to the device structure.
In addition, due to a limitation of this feature, the driver needs to
dynamically enable or disable this feature during run-time. Therefore, add
ASIC interface functions to enable/disable this function from the common
code.
Moreover, this feature must be turned off when the user wishes to debug the
ASIC by reading/writing registers and/or memory through the driver's
debugfs. Therefore, add an option to enable/disable clock gating via the
debugfs interface.

Some devices are not able to cool down by reducing their voltage /
frequency because it could be not available or the system does not
allow voltage scaling. In this configuration, it is not possible to
use this strategy and the idle injection cooling device can be used
instead.
One idle cooling device is now present for the CPU as implemented by
the combination of the idle injection framework belonging to the power
capping framework and the thermal cooling device. The missing part is
the DT binding providing a way to describe how the cooling device will
work on the system.
A first iteration was done by making the cooling device to point to
the idle state. Unfortunately it does not make sense because it would
need to duplicate the idle state description for each CPU in order to
have a different phandle and make the thermal internal framework
happy.
It was proposed to add an cooling-cells to <3>, unfortunately the
thermal framework is expecting a value of <2> as stated by the
documentation and it is not possible from the cooling device generic
code to loop this third value to the back end cooling device.
Another proposal was to add a child 'thermal-idle' node as the SCMI
does. This approach allows to have a self-contained configuration for
the idle cooling device without colliding with the cpufreq cooling
device which is based on the CPU node. In addition, it allows to have
the cpufreq cooling device and the idle cooling device to co-exist
together as shown in the example.
