reproducer:
1. systemctl stop tuned.service
2. tuned-adm profile latency-performance
this shows two type of error.
case 1. invalid pid file
----------------------------
Traceback (most recent call last):
File "/usr/sbin/tuned-adm", line 145, in <module>
tuned_adm.run(args)
File "/usr/sbin/tuned-adm", line 69, in run
self.set_active_profile(args[1])
File "/usr/sbin/tuned-adm", line 129, in set_active_profile
os.kill(pid, signal.SIGHUP)
OSError: [Errno 3] No such process
----------------------------
case 2. no pid file (this caused if /var/run/tuned/tuned.pid isn't there)
-----------------------------------------------------------
Cannot read /var/run/tuned/tuned.pid: [Errno 2] No such file or directory:
'/var/run/tuned/tuned.pid'
-----------------------------------------------------------
description:
- case 1 can be problem if same pid is reused in other process than tuned.
mix with https://bugzilla.redhat.com/show_bug.cgi?id=845336, this can be a
security flaw. pid file should be removed when it found to be invalid.
- case 2 is less problematic, but adding some advisory message is nice to
have. "Please run tuned daemon to configure profile"

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

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

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.

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.
