#34: Please add tool (or option) to show all the options and their values for the selected profile --------------------------+-------------------- Reporter: jskarvad | Owner: Type: enhancement | Status: new Priority: major | Component: daemon Version: 2.0 | Keywords: Blocked By: | Blocking: --------------------------+-------------------- Currently with the introduced inheritance, there should be complex dependencies between profiles. It would be nice to have tool, that would output all the resulting options and their values for the selected profile. -- Ticket URL: <https://fedorahosted.org/tuned/ticket/34> tuned <https://fedorahosted.org/tuned/> A daemon that performs monitoring and adaptive configuration of devices in the system.

[tuned] #47: Create new plugin for process scheduling/priority tuning

#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.

[tuned] #45: Provide white/blacklist for tunings

#45: Provide white/blacklist for tunings ---------------------+-------------------- Reporter: jeder | Owner: Type: defect | Status: new Priority: major | Component: daemon Version: 2.0 | Keywords: Blocked By: | Blocking: ---------------------+-------------------- Tuned sets readahead for all devices to the same value. But a system might have different storage devices attached that require different readahead values (i.e. local storage vs flash). Tuned should provide a way for users to specify readaheads on a per-device basis. This could be implemented as a regex in the profile tuned.conf. i.e. readahead={4096,devices=*} readahead={8192,devices=fio*} Other example tunings that need this feature: - I/O scheduler - Filesystem barriers -- Ticket URL: <https://fedorahosted.org/tuned/ticket/45> tuned <https://fedorahosted.org/tuned/> A daemon that performs monitoring and adaptive configuration of devices in the system.

[tuned] #44: Resolve interaction between tuned and udev

#44: Resolve interaction between tuned and udev ---------------------+-------------------- Reporter: jeder | Owner: Type: defect | Status: new Priority: major | Component: daemon Version: 2.0 | Keywords: Blocked By: | Blocking: ---------------------+-------------------- Vendors use udev rules to apply tunings specific to their application/hardware. Tuned may overwrite these tunings. For example, the user specifies a readahead value of 8192 below. By default, tuned would overwrite this with 4096. Tuned should not overwrite these tunings. cat /etc/udev/rules.d/80-readahead.rules # increase readahead for sd* devices ACTION=="add", KERNEL=="sd*", ATTR{bdi/read_ahead_kb}="8192" -- Ticket URL: <https://fedorahosted.org/tuned/ticket/44> tuned <https://fedorahosted.org/tuned/> A daemon that performs monitoring and adaptive configuration of devices in the system.
