DAMON ABI doc is recommending DAMON admin-guide for people who are willing
to know further about DAMON. Nowadays the subsystem doc
(Documentation/mm/damon) is a more recommended place for even beginners.
Recommend the subsystem doc over admin-guide.

Some hardware monitoring chips support three alarm levels for current and

Add support for currX_emergency, inX_emergency, and inX_lemergency
attributes together with the appropriate alarm attributes to support such
chips.

Add a "preferred" file in /sys/devices/system/cpu/ when kernel is
built with CONFIG_PREFERRED_CPU=y.
This would help
- Users to quickly check which CPUs are marked as preferred.
- Userspace daemons such as irqbalance to use this mask to
route irqs into preferred CPUs.
For example:
cat /sys/devices/system/cpu/online
0-719
cat /sys/devices/system/cpu/preferred
0-599 <<< Implies 0-599 are preferred for workloads and 600-719
should be avoided at this moment.
cat /sys/devices/system/cpu/preferred
0-719 <<< All CPUs are usable. There is no preference.

Currently, the "label" and "acpi_index" attributes are created
whenever the _DSM function 0 bitmap advertises the Device Name
function, without evaluating that function. The documented ABI
states that each attribute is created only if the firmware has
given a name or an instance number to the PCI device.
The bitmap says nothing about the object the function returns.
Firmware that advertises the function but returns an object that
cannot be parsed therefore produces attributes that exist and fail
every read, as in the report below.
Thus, evaluate the Device Name _DSM when deciding attribute visibility
and create each attribute only when the element it exports has a type
the read path accepts, mirroring the checks performed at read time.
The SMBIOS attribute group already follows this pattern by performing
the DMI lookup in its is_visible() callback. The read side checks
remain in place since the two evaluations happen at different times.
This restores the behaviour from before commit 2fc59fe2ecdc ("PCI /
pci-label: treat PCI label with index 0 as valid label"), which
switched visibility from evaluating the function to checking only
the function 0 bitmap. The check is now made for each attribute,
not once for both.
Fixes: 2fc59fe2ecdc ("PCI / pci-label: treat PCI label with index 0 as valid label")

Add /sys/firmware/cca/realm_guest as a stable ABI for detecting whether
the kernel is running as an Arm CCA Realm guest. Create the file only in
Realm world, where it reads 1.
Document the new ABI in Documentation/ABI/testing/sysfs-firmware-cca.

"netdev" can run in hardware control according to hardware capabilities
and trigger options.
Implement hw_offloaded() callback to provide its hardware control state
to the LED core, and document the relation between the custom
"offloaded" attribute and the generic "trigger_may_offload_to_hw"
attribute.
The callback mimics how the existing "offloaded" attribute does, i.e.,
locklessly reads hw_control, as it's just a hint and don't need to be
accurate.

trigger_may_offload_to_hw attribute
There are multiple triggers implementing hardware control. However, the
LED trigger core doesn't really know the hardware control (offloaded)
state since the coordination is done directly between the trigger and
the LED driver. It can only assume private triggers as offloaded and
generic ones as not offloaded.
Add an hw_offloaded() callback so that triggers can report their
offloaded states to the LED trigger core. When unimplemented, it
defaults to true for private triggers and false for generic ones to keep
the current behavior unchanged.
With that, provide a new attribute "trigger_may_offload_to_hw", so that
userspace can determine:
- if the LED device supports hardware control (supported => visible)
- which trigger is the hardware control trigger selected by the LED
device and offloaded to hardware ("[foo_trigger]")
Note: the documentation describes the attribute as "returning a list"
despite the LED core currently only supports one hardware control
trigger per LED device. This is intentional to make the attribute
extensible in the future without breaking userspace. IOW, userspace
should parse the new attribute in the same way as
/sys/class/leds/<led>/trigger.

Since commit b819dc7d8fb2 ("leds: core: Report ENODATA for brightness of
hardware controlled LED"), the brightness attribute becomes write-only
when the LED is controlled fully by the hardware. A write-only attribute
is very confusing.
Moreover, most LED drivers set hardware brightness innocently with the
side effect of disabling hardware control, but the hardware control
trigger remains active, resulting in the software and hardware being out
of sync.
Fix it by removing the hardware control trigger when writing the
brightness attribute.
This should also match the semantics of hardware control:
When the LED is in hw control, no software blink is possible and
doing so will effectively disable hw control.

like EdgeLock Enclave, from:
- User-Space Applications via character driver.
ABI documentation for the NXP secure-enclave driver.
User-space library using this driver:
- i.MX Secure Enclave library:
-- URL: https://github.com/nxp-imx/imx-secure-enclave.git,
- i.MX Secure Middle-Ware:
-- URL: https://github.com/nxp-imx/imx-smw.git
Following checks are performed on the incoming msg-header,
to block exchanging invalid arbitrary commands:
- maximum allowed words,
- check if command-tag & response-tag are valid
- version,
- command id validation check, to allow limited base-line API(s)
and restrict following:
- exchanging power management commands.
- reset requests.
- BBSM configuration requests.
- re-initializing the FW.
- RNG init
- CAAM resource release management
- SE's internal memory management.
from user-space.
