This driver provides an i2c I/O mechanism for the core nct6775 driver,
as might be used by a BMC. Because the Super I/O chip is shared with
the host CPU in such a scenario (and the host should ultimately be in
control of it), the i2c driver is strictly read-only to avoid
interfering with any usage by the host (aside from the bank-select
register, which seems to be replicated for the i2c interface).

These Super I/O chips have an i2c interface that some systems expose

Boards such as
* PRO H410T
* PRIME H410M-R
* ROG STRIX X570-E GAMING WIFI II
have got a nct6775 chip, but by default there's no use of it
because of resource conflict with WMI method.
This commit adds such boards to the WMI monitoring list.

Some include directives are no longer necessary due to previous driver
changes. Remove them now to further improve driver code clarity.
Mutex usage has ceased since commit 719af4f1a40b ("hwmon: (lm83) Use
regmap").
Ever since commit a0ac840d99fa ("hwmon: (lm83) Convert to use
devm_hwmon_device_register_with_groups") functions sysfs_create_group
and sysfs_remove_group are no longer used by the driver.

Some pmbus device drivers have device tree support and
may want to use of-thermal to register a thermal zone
OF sensor for those device drivers.
This way we allow describing device tree thermal zones
for pmbus device drivers with device tree support.
This patch achieves this by registering pmbus sensors
with thermal subsystem if they are PSC_TEMPERATURE
and are providing _input hwmon interface.

The adt7473, adt7475, adt7476 and adt7490 have pins that can be used for
different functions. On the adt7473 and adt7475 this is pins 5 and 9.
On the adt7476 and adt7490 this is pins 10 and 14.
The first pin can either be PWM2(default) or SMBALERT#. The second pin
can be TACH4(default), THERM#, SMBALERT# or GPIO.
The adt7475 driver has always been able to detect the configuration if
it had been done by an earlier boot stage. Add support for configuring
the pins based on the hardware description in the device tree.

Add support for the temperatur sensor and the fan controller on the
Microchip LAN966x SoC. Apparently, an Analog Bits PVT sensor is used
which can measure temperature and process voltages. But only a forumlae
for the temperature sensor is known. Additionally, the SoC support a fan
tacho input as well as a PWM signal to control the fan.

Some temperature and voltage sensors use a polynomial to convert between
raw data points and actual temperature or voltage. The polynomial is
usually the result of a curve fitting of the diode characteristic.
The BT1 PVT hwmon driver already uses such a polynonmial calculation
which is rather generic. Move it to lib/ so other drivers can reuse it.

The macros implementing Atari ROM port I/O writes do not cast away their
output, unlike similar implementations for other I/O buses.
When they are combined using conditional expressions in the definitions of
outb() and friends, this triggers sparse warnings like:
drivers/net/appletalk/cops.c:382:17: error: incompatible types in conditional expression (different base types):
drivers/net/appletalk/cops.c:382:17: unsigned char

When generating callstack information from branch_stack(Intel LBR), the
actual number of callstack entry should be bigger than the number of
branch_stack, for example:
branch_stack records:
B() -> C()
A() -> B()
converted callstack records should be:
C()
B()
A()
though, the number of callstack equals
to the number of branch stack plus 1.
This patch fixes above issue in branch_stack__printf(). For example,
# echo 'scale=2000; 4*a(1)' > cmd
# perf record --call-graph lbr bc -l < cmd

Perf BPF filter test fails in environment where "clang" is not
installed.
Test failure logs:
<<>>
42: BPF filter :
42.1: Basic BPF filtering : Skip
42.2: BPF pinning : FAILED!
42.3: BPF prologue generation : FAILED!
<<>>
Enabling verbose option provided debug logs which says clang/llvm needs
to be installed. Snippet of verbose logs:
<<>>
42.2: BPF pinning :
--- start ---
test child forked, pid 61423
ERROR: unable to find clang.
Hint: Try to install latest clang/llvm to support BPF.

<<logs_here>>
Failed to compile test case: 'Basic BPF llvm compile'
Unable to get BPF object, fix kbuild first
test child finished with -1
---- end ----
BPF filter subtest 2: FAILED!
<<>>
Here subtests, "BPF pinning" and "BPF prologue generation" failed and
logs shows clang/llvm is needed. After installing clang, testcase
passes.
Reason on why subtest failure happens though logs has proper debug
information:
Main function __test__bpf calls test_llvm__fetch_bpf_obj by
passing 4th argument as true ( 4th arguments maps to parameter
"force" in test_llvm__fetch_bpf_obj ). But this will cause
test_llvm__fetch_bpf_obj to skip the check for clang/llvm.
Snippet of code part which checks for clang based on
parameter "force" in test_llvm__fetch_bpf_obj:
<<>>
if (!force && (!llvm_param.user_set_param &&
<<>>
Since force is set to "false", test won't get skipped and fails to
compile test case. The BPF code compilation needs clang, So pass the
fourth argument as "false" and also skip the test if reason for return
is "TEST_SKIP"
After the patch:
<<>>
42: BPF filter :
42.1: Basic BPF filtering : Skip
42.2: BPF pinning : Skip
42.3: BPF prologue generation : Skip

The session topology test fails in powerpc pSeries platform.
Test logs:
<<>>
Session topology : FAILED!
<<>>
This testcases tests cpu topology by checking the core_id and socket_id
stored in perf_env from perf session. The data from perf session is
compared with the cpu topology information from
"/sys/devices/system/cpu/cpuX/topology" like core_id,
physical_package_id.
In case of virtual environment, detail like physical_package_id is
restricted to be exposed. Hence physical_package_id is set to -1. The
testcase fails on such platforms since socket_id can't be fetched from
topology info.
Skip the testcase in powerpc if physical_package_id returns -1.

for_each_shell_test() is already strict in expecting tests to be files
and executable. It is sometimes possible when it iterates over all files
that it finds one that is executable and lacks a newline character. When
this happens the loop never terminates as it doesn't check for EOF.
Add the EOF check to make this loop at least bounded by the file size.
If the description is returned as NULL then also skip the test.

The X86 specific arch__intr_reg_mask() is to check whether the kernel
and hardware can collect XMM registers. But it doesn't work on some
hybrid platform.
Without the patch on ADL-N:
$ perf record -I?
available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10
R11 R12 R13 R14 R15
The config of the test event doesn't contain the PMU information. The
kernel may fail to initialize it on the correct hybrid PMU and return
the wrong non-supported information.
Add the PMU information into the config for the hybrid platform. The
same register set is supported among different hybrid PMUs. Checking
the first available one is good enough.
With the patch on ADL-N:
$ perf record -I?
available registers: AX BX CX DX SI DI BP SP IP FLAGS CS SS R8 R9 R10

"perf all PMU test" picks the input events from "perf list --raw-dump
pmu" list and runs "perf stat -e" for each of the event in the list. In
case of powerpc, the PowerVM environment supports events from hv_24x7
and hv_gpci PMU which is of example format like below:
- hv_24x7/CPM_ADJUNCT_INST,domain=?,core=?/
- hv_gpci/event,partition_id=?/
The value for "?" needs to be filled in depending on system and
respective event. CPM_ADJUNCT_INST needs have core value and domain
value. hv_gpci event needs partition_id. Similarly, there are other
events for hv_24x7 and hv_gpci having "?" in event format. Hence skip
these events on powerpc platform since values like partition_id, domain
is specific to system and event.

greater than 10 ms") made acpi_ex_system_do_sleep() log a warning for
sleep times greater than 10 ms, but such sleep times are used in
power management AML because of the PCI specification requirements.
This results with logging warnings that cannot really be acted on in
any useful way which is annoying and these warnings show up in the logs
on many production systems, so revert commit 6eaf08770ee8.

Rather than pass in a bool for whether or not this work item needs to go
into the priority list or not, provide separate helpers for it. For most
use cases, this also then gets rid of the branch for non-priority task
work.
While at it, rename the prior_task_list to prio_task_list. Prior is
a confusing name for it, as it would seem to indicate that this is the
previous task_work list. prio makes it clear that this is a priority
task_work list.

Before sending a MSI the hardware writes information pertinent to the
interrupt cause to a memory location pointed by SMTICL register. This
memory holds three double words where the least significant bit tells
whether the interrupt cause of master/target/error is valid. The driver
does not use this but we need to set it up because otherwise it will
perform DMA write to the default address (0) and this will cause an
IOMMU fault such as below:
DMAR: DRHD: handling fault status reg 2
DMAR: [DMA Write] Request device [00:12.0] PASID ffffffff fault addr 0
[fault reason 05] PTE Write access is not set
To prevent this from happening, provide a proper DMA buffer for this
that then gets mapped by the IOMMU accordingly.

Pull kvm fixes from Paolo Bonzini:
"ARM:
- Correctly expose GICv3 support even if no irqchip is created so
that userspace doesn't observe it changing pointlessly (fixing a
regression with QEMU)
- Don't issue a hypercall to set the id-mapped vectors when protected
mode is enabled (fix for pKVM in combination with CPUs affected by
Spectre-v3a)

- a NULL pointer dereference on INVPCID executed with paging
disabled, but only if KVM is using shadow paging
- an incorrect bsearch comparison function which could truncate the

with a selftests update too"

Norbert reported that it's possible to race sys_perf_event_open() such
that the looser ends up in another context from the group leader,
triggering many WARNs.
The move_group case checks for races against itself, but the
!move_group case doesn't, seemingly relying on the previous
group_leader->ctx == ctx check. However, that check is racy due to not
holding any locks at that time.
Therefore, re-check the result after acquiring locks and bailing
if they no longer match.
Additionally, clarify the not_move_group case from the
move_group-vs-move_group race.

Several of the manuals for devices supported by this driver describes
the need for a minimum wait time before the chip is ready to receive
next command.
This wait time is already implemented in the driver as a ltc_wait_ready
function with a driver defined wait time of 100 ms, and is considered
for specific devices before reading/writing data on the pmbus.
Since this driver uses the default pmbus_regulator_ops for the enable/
disable/is_enabled functions we should add a driver specific callback
for write_byte_data to prevent bypassing the wait time recommendations
for the following devices: ltc3880/ltc3882/ltc3883/ltc3884/ltc3886/
ltc3887/ltc3889/ltm4664/ltm4675/ltm4676/ltm4677/ltm4678/ltm4680/ltm4686/
ltm4700/ltc7880.

Some of the pmbus core functions uses pmbus_read_byte_data, which does
not support driver callbacks for chip specific write operations. This
could potentially influence some specific regulator chips that for
example need a time delay before each data access.
Lets use _pmbus_read_byte_data with callback check.
