Merge cpuidle updates, PM core updates and changes related to system sleep handling for 6.3-rc1: - Make the TEO cpuidle governor check CPU utilization in order to refine idle state selection (Kajetan Puchalski). - Make Kconfig select the haltpoll cpuidle governor when the haltpoll cpuidle driver is selected and replace a default_idle() call in that driver with arch_cpu_idle() which allows MWAIT to be used (Li RongQing). - Add Emerald Rapids Xeon support to the intel_idle driver (Artem Bityutskiy). - Add ARCH_SUSPEND_POSSIBLE dependencies for ARMv4 cpuidle drivers to avoid randconfig build failures (Arnd Bergmann). - Make kobj_type structures used in the cpuidle sysfs interface constant (Thomas Weißschuh). - Make the cpuidle driver registration code update microsecond values of idle state parameters in accordance with their nanosecond values if they are provided (Rafael Wysocki). - Make the PSCI cpuidle driver prevent topology CPUs from being suspended on PREEMPT_RT (Krzysztof Kozlowski). - Document that pm_runtime_force_suspend() cannot be used with DPM_FLAG_SMART_SUSPEND (Richard Fitzgerald). - Add EXPORT macros for exporting PM functions from drivers (Richard Fitzgerald). - Drop "select SRCU" from system sleep Kconfig (Paul E. McKenney). - Remove /** from non-kernel-doc comments in hibernation code (Randy Dunlap). * pm-cpuidle: cpuidle: psci: Do not suspend topology CPUs on PREEMPT_RT cpuidle: driver: Update microsecond values of state parameters as needed cpuidle: sysfs: make kobj_type structures constant cpuidle: add ARCH_SUSPEND_POSSIBLE dependencies intel_idle: add Emerald Rapids Xeon support cpuidle-haltpoll: Replace default_idle() with arch_cpu_idle() cpuidle-haltpoll: select haltpoll governor cpuidle: teo: Introduce util-awareness cpuidle: teo: Optionally skip polling states in teo_find_shallower_state() * pm-core: PM: Add EXPORT macros for exporting PM functions PM: runtime: Document that force_suspend() is incompatible with SMART_SUSPEND * pm-sleep: PM: sleep: Remove "select SRCU" PM: hibernate: swap: don't use /** for non-kernel-doc comments
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
