#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] #32: tuned-adm list, active, profile should work even if the daemon is stopped

#32: tuned-adm list, active, profile should work even if the daemon is stopped -----------------------+-------------------- Reporter: jskarvad | Owner: Type: defect | Status: new Priority: major | Component: daemon Version: 2.0 | Keywords: Blocked By: | Blocking: -----------------------+-------------------- Currently it is not possible to set the profile before the daemon is started. You need to start the daemon (with unwanted profile) and then change to required profile. There is the same problem if you need to only observe which profiles are available on your system - you need to start the daemon. This is weird. Proposal: - the tuned-adm should query the data on filesystem directly if the dbus call fail. - for set_profile there should be locking, i.e. during the initialization of the daemon, if there is tuned-adm running, the daemon should wait for tuned-adm completion. -- Ticket URL: <https://fedorahosted.org/tuned/ticket/32> tuned <https://fedorahosted.org/tuned/> A daemon that performs monitoring and adaptive configuration of devices in the system.

Fedora 19 Power Management Test Day
by Jaroslav Skarvada 16 Apr '13

16 Apr '13

Fedora 19 power management test day will start this Wednesday (2013-04-17). The event will be mainly focused on laptops, but even desktop machines can be tested. There are also prepared three test cases which are suitable for secondary architectures, thus e.g. if you are running Fedora 19 pre-release on your ARM box, please join us and share your numbers. There are also prepared special test cases targeting aggressive power-savings on Intel, Nvidia and ATI / AMD (Radeon) graphics cards. This is also on-site event that is running along with the Redhat Open House event. So if you are near Brno, feel free to join us in person. You can bring your hardware and test it there. There will be available calibrated digital power meter (Chroma 66202) so you will be able to measure power consumption of your hardware. Live USB/CD will be available so you can participate in the test day without affecting your production machine. There is also prepared new web application which you can use for submitting your results, but if you prefer the wiki, you can still submit your results through the wiki as usual. Everybody is welcome to attend this event and your attendance will help us to make the Fedora better. Going through all test cases take less an hour, but you don't need to finish them all - just select test cases you are interested in, partial results are also valuable for us. Just visit the PM test day WWW page [1] and follow on-site instructions or join us in person [2] thanks & regards Jaroslav [1] http://fedoraproject.org/wiki/Test_Day:2013-04-17_Power_Management [2] http://redhatopenhouse.shdlr.com/grid
