Add function to set a custom coredump timeout.
For Xe driver usage, current 5 minutes timeout may be too short for
users to search and understand what needs to be done to capture
coredump to report bugs.
We have plans to automate(distribute a udev script) it but at the end
will be up to distros and users to pack it so having a option to
increase the timeout is a safer option.
v2:
- replace dev_coredump_timeout_set() by dev_coredumpm_timeout() (Mukesh)
v3:
- make dev_coredumpm() static inline (Johannes)
v5:
- rename DEVCOREDUMP_TIMEOUT -> DEVCD_TIMEOUT to avoid redefinition
in include/net/bluetooth/coredump.h
v6:
- fix definition of dev_coredumpm_timeout() when CONFIG_DEV_COREDUMP
is disabled

Synchronize the dev->driver usage in really_probe() and dev_uevent().
These can run in different threads, what can result in the following
race condition for dev->driver uninitialization:
Thread #1:
==========
really_probe() {
...
probe_failed:
...
device_unbind_cleanup(dev) {
...
dev->driver = NULL; // <= Failed probe sets dev->driver to NULL
...
}
...
}
Thread #2:
==========
dev_uevent() {
...
if (dev->driver)
// If dev->driver is NULLed from really_probe() from here on,
// after above check, the system crashes
add_uevent_var(env, "DRIVER=%s", dev->driver->name);
...
}
really_probe() holds the lock, already. So nothing needs to be done
there. dev_uevent() is called with lock held, often, too. But not
always. What implies that we can't add any locking in dev_uevent()
itself. So fix this race by adding the lock to the non-protected
path. This is the path where above race is observed:
dev_uevent+0x235/0x380
uevent_show+0x10c/0x1f0 <= Add lock here
dev_attr_show+0x3a/0xa0
sysfs_kf_seq_show+0x17c/0x250
kernfs_seq_show+0x7c/0x90
seq_read_iter+0x2d7/0x940
kernfs_fop_read_iter+0xc6/0x310
vfs_read+0x5bc/0x6b0
ksys_read+0xeb/0x1b0
__x64_sys_read+0x42/0x50
x64_sys_call+0x27ad/0x2d30
do_syscall_64+0xcd/0x1d0
entry_SYSCALL_64_after_hwframe+0x77/0x7f
Similar cases are reported by syzkaller in
https://syzkaller.appspot.com/bug?extid=ffa8143439596313a85a
But these are regarding the *initialization* of dev->driver
dev->driver = drv;
As this switches dev->driver to non-NULL these reports can be considered
to be false-positives (which should be "fixed" by this commit, as well,
though).
The same issue was reported and tried to be fixed back in 2015 in
https://lore.kernel.org/lkml/1421259054-2574-1-git-send-email-a.sangwan@samsung.com/

Currently, when an adapter defines a max_write_len quirk,
the data will be chunked into data sizes equal to the
max_write_len quirk value. But the payload will be increased by
the size of the register address before transmission. The
resulting value always ends up larger than the limit set
by the quirk.
Avoid this error by setting regmap's max_write to the quirk's
max_write_len minus the number of bytes for the register and
padding. This allows the chunking to work correctly for this
limited case without impacting other use-cases.

With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.
This means that with:
__string(field, mystring)
Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.
There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:
git grep -l __assign_str | while read a ; do
sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
mv /tmp/test-file $a;
done
I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.
Note, the same updates will need to be done for:
__assign_str_len()
__assign_rel_str()
__assign_rel_str_len()
I tested this with both an allmodconfig and an allyesconfig (build only for both).

Force the max_register of the test regmap to be one register longer
than the number of test registers, to prevent an array overflow in
the test loop.
The test defines num_reg_defaults = 6. With 6 registers and
stride == 2 the valid register addresses would be 0, 2, 4, 6, 8, 10.
However the loop checks attempting to access the odd address, so on
the final register it accesses address 11, and it writes entry [11]
of the read/written arrays.
Originally this worked because the max_register of the regmap was
hardcoded to be BLOCK_TEST_SIZE (== 12).
commit 710915743d53 ("regmap: kunit: Run sparse cache tests at non-zero
register addresses")
introduced the ability to start the test address range from any address,
which means adjusting the max_register. If max_register was not forced,
it was calculated either from num_reg_defaults or BLOCK_TEST_SIZE. This
correctly calculated that with num_reg_defaults == 6 and stride == 2 the
final valid address is 10. So the read/written arrays are allocated to
contain entries [0..10]. When stride attempted to access [11] it was
overflowing the array.

Using 'hw_pressure' for local variable name is confusing in regard to the
per-CPU 'hw_pressure' variable that uses the same name:
include/linux/arch_topology.h:DECLARE_PER_CPU(unsigned long, hw_pressure);
... which puts it into a global scope for all code that includes
<linux/topology.h>, shadowing the local variable.
Rename it to avoid compiler confusion & Sparse warnings.

For drivers wishing to expose an unsigned long, int or bool at a static
memory location in sysfs, the driver core provides ready-made helpers
such as device_show_ulong() to be used as ->show() callback.
Some drivers need to expose a string and so far they all provide their
own ->show() implementation. arch/powerpc/perf/hv-24x7.c went so far
as to create a device_show_string() helper but kept it private.
Make it public for reuse by other drivers. The pattern seems to be
sufficiently frequent to merit a public helper.
Add a DEVICE_STRING_ATTR_RO() macro in line with the existing
DEVICE_ULONG_ATTR() and similar macros to ease declaration of string
attributes.

arch_update_hw_pressure()
Now that cpufreq provides a pressure value to the scheduler, rename
arch_update_thermal_pressure into HW pressure to reflect that it returns
a pressure applied by HW (i.e. with a high frequency change) and not
always related to thermal mitigation but also generated by max current
limitation as an example. Such high frequency signal needs filtering to be
smoothed and provide an value that reflects the average available capacity
into the scheduler time scale.

IIO: 1st set of new device support, features and cleanup for 6.10
The Analog Device team (Paul Cercueil and Nuno Sa) have been working on
improving high speed device handling. They have had some support in their
own tree for many years, so it is great to see them bring it to upstream.
Some of that is seen here, with the first output device using the
IIO dmaengine infrastructure and a new DAC backend FPGA IP driver.
This makes use of a new set of interfaces to allow backend and
front end driver communication in a fashion that in theory at least
allows for a single driver for a given ADC / DAC independent of
the IP to which is being used to deal with the data bus and DMA aspects
of working with these devices. It is early days for this new
generic way of handling split devices, but as it's kernel internals only
we can merrily change anything about it as a wider diversity of devices
show up and we get a better feel for what works.
Alongside the usual set of new drivers and features we have
the automatic cleanup of fwnode_handle_put() which didn't quite make
it in last cycle. The equivalent DT version was merged by Rob Herring
via the DT binding tree and one patch using that in IIO can also be
found in this pull request. Rob has been making extensive use of that
infrastructure in the DT core which is good to see and provides more
evidence this basic approach is useful.
In some cases, the IIO driver was converted over from DT only to
using the generic firmware description handling of property.h
including using the new macros. The general preference for IIO
is to use this more generic handling where possible - a bunch of other
drivers have been converted this cycle as well.
New device support
==================
adi,ad7173
- New driver supporting AD7172-2, AD7172-4 AD7173-9, AD7175-2, AD7175-8,
AD7176-2 and AD7177-2 ADCs.
- Follow up fix for an accidental use of logic not instead of bitwise.
adi,ad7944
- New driver supporting AD7944, AD7985 and AD7986 pin compatible ADCs.
- Later patch added use of new spi_optimize_message() to reduce overheads
of setting up a reused message.
- Additional changes later in series reduced code duplication.
adi,ad9739a RF DAC
- New driver for this 14-bit 2.5 GSPS DAC via an LVDS interface.
adi,axi-dac
- Support for this FPGA IP used to send data to high performance DACs over
an interface such as JESD204B/C or parallel interfaces. Used in
conjunction with a DAC driver. The initial user is the ad9739a.
The dmaengine-buffer needed various changes to make it bidirectional.
avago,apds9306
- New driver for this ambient light sensor.
- Fix much later in this pull for an off by 1 error.
New device IDs
==============
For these at most an ID and a instance of chip specific data was needed.
Always nice to see manufacturers sticking to an existing software interface
for new parts.
allwinner,sun20i
- Add support for h616.
invensense,mpu6050
- Add support for ICM42688
maxim,max30102
- Add compatible for MAX30101
ti,dac5571
- Add compatible for DAC081C081
General
=======
fwnode_handle
- Support for cleanup.h based __free(fwnode_handle)
- Loop macro using this for looping over child nodes without needing to
call fwnode_handle_put() in ever early exit from the loop.
- Used in:
* adi,ad3552r
* adi,ad4130
* adi,ad5770r
* adi,ad74413r
* adi,ad7173
* adi,adfm2000
* linear,ltc2688
* linear,ltc2983
* maxim,max11410
* microchip,pac1934
* qcom,spmi-adc
* renesas,rz2gl
* st,ab8500
* st,stm32 (Fix for failure to set return value precedes this patch,
providing an example of why enabling direct returns makes bugs
less likely)
- Conversions to fwnode also using the cleanup logic
* adi,ad7124
* adi,ad7292
* freescale,fsl-imx25-gcq
- Other conversions to fwnode where the new cleanup handling isn't useful
* adi,ad7192
* avia,hx711
* freescale,mma8452
* nxp,fxls8962af
* st,spear
* ti,twl4030
Features
========
adi,adxl345
- Support SPI_3WIRE mode.
adi,ad9944
- Support 3-wire mode, note this isn't normal 3-wire SPI (unlike the
adxl345 change above), but rather a wiring scheme where the SPI
chip select is used to trigger conversions rather than using a
separate pin.
- Add some device specific documentation, mostly around the various wiring
schemes.
invensense,mpu6050
- Add Wake on Motion support as an IIO event and as a wake-up source.
linear,ltc2983
- Add vdd-supply.
ti,hdc3020
- Add power management using trigger on demand mode and adding suspend and
resume handling.
- Use reset GPIO if available.
Cleanup and fixes
================
iio core
- Use the various autocleanup and lock guards from cleanup.h to simplify
the IIO core.
- Don't set the pointer used for iio_priv() if it is zero sized as that
points beyond the end of the allocation. No driver actually uses it
in that case but good to clean this up.
various drivers
- Drop unnecessary casts of other pointer types to void *
docs
- Add missing ABI entry for in_temp_input.
adi,adx345
- General cleanup prior to adding spi-3wire mode.
adi,axi-adc
- Be more flexible and allow minor version changes as these are expected
to be backwards compatible.
avago,apds9300/9600
- Merge near identical bindings. The drivers are quite different, but
the bindings can be shared. The apds9306 binding introduced in this
series uses this shared binding doc as well.
- Add missing vdd-supply
- Update binding to use IRQ_TYPE_LEVEL_LOW instead of 8.
bosch,bmp280
- Organize headers
freescale,fxl-imx25-gcq
- Use devm_ for remaining probe() time setup allowing dropping
of specific error handling and remove() functions.
infineon,dps310
- Fix handling of negative temperatures
- Bring style of other similar calls inline with the form needed
for temperatures
- Ensure error handling of regmap calls is consistent within the driver.
- Simplify scale reading logic.
invensense,mpu6050
- Flip logic in binding to exclude devices without i2c-gate instead
of opting in. The list is expected to be much shorter as all recent
devices support this feature.
honeywell,hsc030pa
- Use spi_read() instead of opening coding.
renesas,rcar
- Use device_for_each_child_of_node_scoped() to remove need to manually
release. Left over from series the rest of which went in during 6.9.
st,ab8500
- Fix naming of function parameters in kernel-doc

Commit a72bbec70da2 ("crash: hotplug support for kexec_load()")
introduced a new kexec flag, `KEXEC_UPDATE_ELFCOREHDR`. Kexec tool uses
this flag to indicate to the kernel that it is safe to modify the
elfcorehdr of the kdump image loaded using the kexec_load system call.
However, it is possible that architectures may need to update kexec
segments other then elfcorehdr. For example, FDT (Flatten Device Tree)
on PowerPC. Introducing a new kexec flag for every new kexec segment
may not be a good solution. Hence, a generic kexec flag bit,
`KEXEC_CRASH_HOTPLUG_SUPPORT`, is introduced to share the CPU/Memory
hotplug support intent between the kexec tool and the kernel for the
kexec_load system call.
Now we have two kexec flags that enables crash hotplug support for
kexec_load system call. First is KEXEC_UPDATE_ELFCOREHDR (only used in
x86), and second is KEXEC_CRASH_HOTPLUG_SUPPORT (for all architectures).
To simplify the process of finding and reporting the crash hotplug
support the following changes are introduced.
1. Define arch specific function to process the kexec flags and
determine crash hotplug support
2. Rename the @update_elfcorehdr member of struct kimage to
@hotplug_support and populate it for both kexec_load and
kexec_file_load syscalls, because architecture can update more than
one kexec segment
3. Let generic function crash_check_hotplug_support report hotplug
support for loaded kdump image based on value of @hotplug_support
To bring the x86 crash hotplug support in line with the above points,
the following changes have been made:
- Introduce the arch_crash_hotplug_support function to process kexec
flags and determine crash hotplug support
- Remove the arch_crash_hotplug_[cpu|memory]_support functions

The kunit_device_register() function returns error pointers, not NULL.
Passing an error pointer to get_device() will lead to an Oops. Also

The sysfs_create_link() return code is marked as __must_check, but the
module_add_driver() function tries hard to not care, by assigning the
return code to a variable. When building with 'make W=1', gcc still
warns because this variable is only assigned but not used:
drivers/base/module.c: In function 'module_add_driver':
drivers/base/module.c:36:6: warning: variable 'no_warn' set but not used [-Wunused-but-set-variable]
Rework the code to properly unwind and return the error code to the
caller. My reading of the original code was that it tries to
not fail when the links already exist, so keep ignoring -EEXIST
errors.

Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:
This series adds some more test cases, mainly for testing:
commit eaa03486d932 ("regmap: maple: Fix uninitialized symbol 'ret' warnings")
commit 00bb549d7d63 ("regmap: maple: Fix cache corruption in regcache_maple_drop()")
And the pending patch ("regmap: Add regmap_read_bypassed()")
There are also a few small improvements to the KUnit implementation.

Add a test case for dropping only some cache blocks and leaving others
unchanged.
The regmap is divided into 8 register ranges, and only 4 of these are
written with values. This creates 4 non-contiguous ranges of registers
with cached values.
One whole range is then dropped, and part of another range. A cache
sync is then performed to check that the correct registers were written,
and the correct values were written to these registers.

Extend the testing of cache-sync.
- cache_sync() renamed cache_sync_marked_dirty() for clarity of
what conditions it is testing.
- cache_sync_defaults() renamed cache_sync_defaults_marked_dirty()
for clarity. Added code to write the register back to its default
value to check that a dirty sync doesn't write out the default value.
- Added cache_sync_after_cache_only(). Tests syncing the cache without
calling regcache_mark_dirty(). A register written while in cache-only
should be written out by regcache_sync().
- Added cache_sync_default_after_cache_only. This is similar to
cache_sync_after_cache_only(), but the register is changed to its
default value while in cache-only. Because regcache_mark_dirty() was
NOT called, regacache_sync() should write out the register.

Extend the testing of cache-drop.
- Added cache_drop_all_and_sync_marked_dirty(). If all registers are
dropped from the cache a regcache_mark_dirty() followed by
regcache_sync() should not write anything because the cache is empty.
- Added cache_drop_all_and_sync_no_defaults(). This is similar to
cache_drop_all_and_sync_marked_dirty() except that regcache_mark_dirty()
is NOT called. All registers were dropped so regcache_sync() should not
write anything.
- Added cache_drop_all_and_sync_has_defaults(). This is the same as
cache_drop_all_and_sync_no_defaults() except that the regmap has a
table of default values.

Change the tests parameterized by real_cache_types_list[] to test at some
register addresses that are not 0.
The cache_range_window_reg() test has hardcoded address assumptions that
are not present in any other tests using real_cache_types_list[] table. So
it has been given a separate parameter table, real_cache_types_only_list[],
that preserves the original parameterization.

Run the cache_drop() and cache_present() tests at blocks of addresses
that don't start at zero.
This adds a from_reg parameter to struct regmap_test_param. This is
used to set the base address of the register defaults created by
gen_regmap().
Extra entries are added to sparse_cache_types_list[] to test at non-zero
from_reg values. The cache_drop() and cache_present() tests are updated
to test at the given offset.
The aim here is to add test cases to cache_drop() for the bug fixed by
commit 00bb549d7d63 ("regmap: maple: Fix cache corruption in
regcache_maple_drop()")
But the same parameter table is used by the cache_present() test so
let's also update that to use from_reg.

Use kunit_device_register() to create a real struct device for the
regmap instead of leaving it at NULL.
The main reason for this is that it allows context data to be passed
into the readable_reg/writable_reg/volatile_reg functions by attaching
it to the struct device with dev_set_drvdata().
The gen_regmap() and gen_raw_regmap() functions are updated to take a
struct kunit * argument.
A new struct regmap_test_priv has been created to hold the struct device
created by kunit_device_register(). This allows the struct to be
extended in the future to hold more private data for the test suite.

Add a regmap_read_bypassed() to allow reads from the hardware registers
while the regmap is in cache-only mode.
A typical use for this is to keep the cache in cache-only mode until
the hardware has reached a valid state, but one or more status registers
must be polled to determine when this state is reached.
For example, firmware download on the cs35l56 can take several seconds if
there are multiple amps sharing limited bus bandwidth. This is too long
to block in probe() so it is done as a background task. The device must
be soft-reset to reboot the firmware and during this time the registers are
not accessible, so the cache should be in cache-only. But the driver must
poll a register to detect when reboot has completed.
