platform/x86: Update Mario Limonciello's email address in the docs

2021-08-13T11:18:15Z

Various pdx86 docs under Documentation/ABI/testing still use Mario's old, now defunct, address. Update the docs to point to either the new Dell.Client.Kernel@dell.com email alias for Dell specific drivers, or to Mario's new @outlook.com address for other drivers.

docs: ABI: cleanup several ABI documents

2020-10-30T12:14:29Z

There are some ABI documents that, while they don't generate any warnings, they have issues when parsed by get_abi.pl script on its output result. Address them, in order to provide a clean output.

PM: suspend: Add sysfs attribute to control the "sync on suspend" behavior

2020-01-16T20:47:03Z

The sysfs attribute `/sys/power/sync_on_suspend` controls, whether or not filesystems are synced by the kernel before system suspend. Congruously, the behaviour of build-time switch CONFIG_SUSPEND_SKIP_SYNC is slightly changed: It now defines the run-tim default for the new sysfs attribute `/sys/power/sync_on_suspend`. The run-time attribute is added because the existing corresponding build-time Kconfig flag for (`CONFIG_SUSPEND_SKIP_SYNC`) is not flexible enough. E.g. Linux distributions that provide pre-compiled kernels usually want to stick with the default (sync filesystems before suspend) but under special conditions this needs to be changed. One example for such a special condition is user-space handling of suspending block devices (e.g. using `cryptsetup luksSuspend` or `dmsetup suspend`) before system suspend. The Kernel trying to sync filesystems after the underlying block device already got suspended obviously leads to dead-locks. Be aware that you have to take care of the filesystem sync yourself before suspending the system in those scenarios. Signed-off-by: Jonas Meurer Signed-off-by: Rafael J. Wysocki

PM/sleep: Expose suspend stats in sysfs

2019-08-05T10:03:18Z

Userspace can get suspend stats from the suspend stats debugfs node. Since debugfs doesn't have stable ABI, expose suspend stats in sysfs under /sys/power/suspend_stats. Signed-off-by: Kalesh Singh Reviewed-by: Greg Kroah-Hartman Signed-off-by: Rafael J. Wysocki

PM / hibernate: Documentation: fix image_size default value

2018-09-10T10:07:06Z

This commit updates the default value of /sys/power/image_size in the documentation. Since ac5c24ec1e983313ef0015258fba6f630e54e7cn the `image_size' value is set to about 2/5 of RAM, according to kernel/power/snapshot.c: image_size = ((totalram_pages * 2) / 5) * PAGE_SIZE; but this change was not reflected everywhere in the documentation.

PM / hibernate: Make passing hibernate offsets more friendly

2018-03-30T10:01:20Z

Currently the only way to specify a hibernate offset for a swap file is on the kernel command line. Add a new /sys/power/resume_offset that lets userspace specify the offset and disk to use when initiating a hibernate cycle. Signed-off-by: Mario Limonciello Signed-off-by: Rafael J. Wysocki

Merge tag 'docs-4.15' of git://git.lwn.net/linux

Pull documentation updates from Jonathan Corbet: "A relatively calm cycle for the docs tree again. - The old driver statement has been added to the kernel docs. - We have a couple of new helper scripts. find-unused-docs.sh from Sayli Karnic will point out kerneldoc comments that are not actually used in the documentation. Jani Nikula's documentation-file-ref-check finds references to non-existing files. - A new ftrace document from Steve Rostedt. - Vinod Koul converted the dmaengine docs to RST Beyond that, it's mostly simple fixes. This set reaches outside of Documentation/ a bit more than most. In all cases, the changes are to comment docs, mostly from Randy, in places where there didn't seem to be anybody better to take them" * tag 'docs-4.15' of git://git.lwn.net/linux: (52 commits) documentation: fb: update list of available compiled-in fonts MAINTAINERS: update DMAengine documentation location dmaengine: doc: ReSTize pxa_dma doc dmaengine: doc: ReSTize dmatest doc dmaengine: doc: ReSTize client API doc dmaengine: doc: ReSTize provider doc dmaengine: doc: Add ReST style dmaengine document ftrace/docs: Add documentation on how to use ftrace from within the kernel bug-hunting.rst: Fix an example and a typo in a Sphinx tag scripts: Add a script to find unused documentation samples: Convert timers to use timer_setup() documentation: kernel-api: add more info on bitmap functions Documentation: fix selftests related file refs Documentation: fix ref to power basic-pm-debugging Documentation: fix ref to trace stm content Documentation: fix ref to coccinelle content Documentation: fix ref to workqueue content Documentation: fix ref to sphinx/kerneldoc.py Documentation: fix locking rt-mutex doc refs docs: dev-tools: correct Coccinelle version number ...
