#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] #42: tuned profile CPU governor controls must account for CPU generation

#42: tuned profile CPU governor controls must account for CPU generation ---------------------+-------------------- Reporter: jeder | Owner: Type: defect | Status: new Priority: major | Component: daemon Version: 2.0 | Keywords: Blocked By: | Blocking: ---------------------+-------------------- tuned profiles currently utilize CPU "governors" to configure cpufreq. With newer generation chips from Intel, this capability will go away, and we need tuned to support both older and current generations as well as newer generations, from different vendors such as ARM-based chips. So the specification for functional performance levels must be abstracted, and, based on the system hardware, would implement the required tuning. For example, newer generations of Intel CPUs default to the intel_pstate driver upstream and in Fedora. In order for tuned to handle these Sandy Bridge and newer chips, it will need to be taught about the intel_pstate driver, which has different knobs in sysfs. Setting governor=ondemand will be useless on systems where the kernel detects newer Intel chips and thus uses intel_pstate. For example, tuned could key off of the model number in /proc/cpuinfo (or similar). model : 45 model name : Intel(R) Xeon(R) CPU E5-2630 0 @ 2.30GHz Then if it finds a certain Intel model number or greater, it would skip setting ondemand. Ondemand is the new default of intel_pstate. $ for i in `find /sys/devices/system/cpu/intel_pstate -type f` ; do echo -n "$i: " ; cat $i ; done /sys/devices/system/cpu/intel_pstate/max_perf_pct: 100 /sys/devices/system/cpu/intel_pstate/no_turbo: 0 /sys/devices/system/cpu/intel_pstate/min_perf_pct: 31 All profiles that contain governor=performance have to set min_perf_pct=100. The default is currently 31. -- Ticket URL: <https://fedorahosted.org/tuned/ticket/42> 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.
