Docs/subsystem-apis: Remove '[The ]Linux' prefixes from titles of listed documents

2023-01-24T22:27:08+00:00

Some documents that listed on subsystem-apis have 'Linux' or 'The Linux' title prefixes. It's duplicated information, and makes finding the document of interest with human eyes not easy. Remove the prefixes from the titles.

watchdog/pseries-wdt: initial support for H_WATCHDOG-based watchdog timers

2022-07-20T11:57:39+00:00

PAPR v2.12 defines a new hypercall, H_WATCHDOG. The hypercall permits guest control of one or more virtual watchdog timers. The timers have millisecond granularity. The guest is terminated when a timer expires. This patch adds a watchdog driver for these timers, "pseries-wdt". pseries_wdt_probe() currently assumes the existence of only one platform device and always assigns it watchdogNumber 1. If we ever expose more than one timer to userspace we will need to devise a way to assign a distinct watchdogNumber to each platform device at device registration time.

watchdog: add support for adjusting last known HW keepalive time

2020-08-05T16:43:02+00:00

Certain watchdogs require the watchdog only to be pinged within a specific time window, pinging too early or too late cause the watchdog to fire. In cases where this sort of watchdog has been started before kernel comes up, we must adjust the watchdog keepalive window to match the actually running timer, so add a new driver API for this purpose.

docs: watchdog: codify ident.options as superset of possible status flags

2020-08-05T16:42:52+00:00

The FIXME comment has been in-tree since the very first git commit. The described behavior has been since relied on by some userspace, e.g. the util-linux wdctl command and has been ignored by some kernelspace, like the f71808e_wdt driver. The functionality is useful to have to be able to differentiate between a driver that doesn't support WDIOF_CARDRESET and one that does, but hasn't had a watchdog reset, thus drop the FIXME to encourage drivers adopting this convention.
