#47: Create new plugin for process scheduling/priority tuning --------------------------+-------------------- Reporter: jeder | Owner: Type: enhancement | Status: new Priority: major | Component: daemon Version: 2.0 | Keywords: Blocked By: | Blocking: --------------------------+-------------------- We have an init-based service now that, upon boot, applies some scheduler tuning to regexes matching threads. Below is an example: # Format is: <groupname>:<sched>:<prio>:affinity:<regex> kthreads:*:1:*:\[.*\]$ watchdog:f:99:*:\[watchdog.*\] migration:f:99:*:\[migration\/.*\] softirq:f:70:*:\[.*(softirq|sirq).*\] softirq-net-tx:f:75:*:\[(softirq|sirq)-net-tx.*\] softirq-net-rx:f:75:*:\[(softirq|sirq)-net-rx.*\] softirq-sched:f:1:*:\[(softirq|sirq)-sched\/.*\] rpciod:f:65:*:\[rpciod.*\] lockd:f:65:*:\[lockd.*\] nfsd:f:65:*:\[nfsd.*\] hardirq:f:85:*:\[(irq|IRQ)[\-_/].*\] We would like to move this functionality from the init system to a tuned profile, but it doesn't seem possible with the current tuned capabilities/plugins. In addition to one-shot tuning during profile load, there is also a use- case for monitoring new processes that are created, and applying this tuning. This could be a watchdog/scanning behavior in tuned daemon (not preferred because it creates background noise), or something more clever using perf events or even LD_PRELOAD of exec function call. -- Ticket URL: <https://fedorahosted.org/tuned/ticket/47> tuned <https://fedorahosted.org/tuned/> A daemon that performs monitoring and adaptive configuration of devices in the system.
