* watchdog: add setting to configure pretimeout governorLuca Boccassi2022-02-221-0/+1

* watchdog: Add watchdog pretimeout supportCurtis Klein2022-02-221-0/+1
| | | | | | | | | | | | | | Add support for managing and configuring watchdog pretimeout values if the watchdog hardware supports it. The ping interval is adjusted to account for a pretimeout so that it will still ping at half the timeout interval before a pretimeout event would be triggered. By default the pretimeout defaults to 0s or disabled. The RuntimeWatchdogPreSec config option is added to allow the pretimeout to be specified (similar to RuntimeWatchdogSec). The RuntimeWatchdogPreUSec dbus property is added to override the pretimeout value at runtime (similar to RuntimeWatchdogUSec). Setting the pretimeout to 0s will disable the pretimeout.

* watchdog: rename watchdog_set_timeout() into watchdog_setup()Franck Bui2021-09-151-1/+1
| | | | | "watchdog_set_timeout()" was misleading as the function is not just a setter - it must be called for activating the watchdog device.
* core: watchdog_set_timeout() doesn't need to return the timeout value used ↵Franck Bui2021-09-151-1/+1
| | | | | | | by the HW The manager currently doesn't need it and if it does in the future an helper should probably be introduced instead.

* watchdog: reduce watchdog pings in timeout intervalAlin Popa2020-04-161-0/+1
| | | | | | | | | | The watchdog ping is performed for every iteration of manager event loop. This results in a lot of ioctls on watchdog device driver especially during boot or if services are aggressively using sd_notify. Depending on the watchdog device driver this may have performance impact on embedded systems. The patch skips sending the watchdog to device driver if the ping is requested before half of the watchdog timeout.
* tree-wide: remove Lennart's copyright linesLennart Poettering2018-06-141-4/+0
| | | | | | | | | | | These lines are generally out-of-date, incomplete and unnecessary. With SPDX and git repository much more accurate and fine grained information about licensing and authorship is available, hence let's drop the per-file copyright notice. Of course, removing copyright lines of others is problematic, hence this commit only removes my own lines and leaves all others untouched. It might be nicer if sooner or later those could go away too, making git the only and accurate source of authorship information.
* tree-wide: drop 'This file is part of systemd' blurbLennart Poettering2018-06-141-2/+0
| | | | | | | | | | | | | | | | This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.
* tree-wide: drop license boilerplateZbigniew Jędrzejewski-Szmek2018-04-061-13/+0
| | | | | | | | | | Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.
* watchdog: allow a device path to be specifiedEdward A. James2017-12-081-0/+5
| | | | | | | | | Currently systemd hardcodes the use of /dev/watchdog. This is a legacy chardev that points to watchdog0 in the system. Modify the watchdog API to allow a different device path to be passed and stored. Opening the watchdog defaults to /dev/watchdog, maintaining existing behavior.
* Add SPDX license identifiers to source files under the LGPLZbigniew Jędrzejewski-Szmek2017-11-191-0/+1
| | | | | This follows what the kernel is doing, c.f. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5fd54ace4721fc5ce2bb5aef6318fcf17f421460.
* tree-wide: remove Emacs lines from all filesDaniel Mack2016-02-101-2/+0
| | | | | This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
* shared: include what we useThomas Hindoe Paaboel Andersen2015-12-061-0/+3
| | | | | The next step of a general cleanup of our includes. This one mostly adds missing includes but there are a few removals as well.
* use #pragma once instead of foo*foo #define guardsShawn Landden2012-07-191-4/+1
| | | | | | | | | | | | | | | | | #pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers
* move more common files to shared/ and add them to shared.laKay Sievers2012-04-121-0/+31
