--- Comment #5 from A V <napseis@xxxxxxxxx> ---
hi, I have no special kernel configuration. I had "nomodeset", but removing it
doesn't help.

uname -r
4.4.27-2-default

I'm not using "tuned".

As for what you asked, here is the output from my laptop:

cat /sys/devices/system/cpu/intel_pstate/max_perf_pct
100


cat /sys/devices/system/cpu/intel_pstate/min_perf_pct
22

cat /sys/devices/system/cpu/intel_pstate/no_turbo
0

cat /sys/devices/system/cpu/intel_pstate/num_pstates
28

cat /sys/devices/system/cpu/intel_pstate/turbo_pct
33

num_pstates and turbo_pct looks funny...

I also add i7z output:

Cpu speed from cpuinfo 2693.00Mhz
cpuinfo might be wrong if cpufreq is enabled. To guess correctly try estimating
via tsc
Linux's inbuilt cpu_khz code emulated now
True Frequency (without accounting Turbo) 2693 MHz
CPU Multiplier 27x || Bus clock frequency (BCLK) 99.74 MHz

Socket [0] - [physical cores=4, logical cores=8, max online cores ever=4]
TURBO ENABLED on 4 Cores, Hyper Threading ON
Max Frequency without considering Turbo 2792.74 MHz (99.74 x [28])
Max TURBO Multiplier (if Enabled) with 1/2/3/4 Cores is 35x/35x/35x/35x
Real Current Frequency 3491.06 MHz [99.74 x 35.00] (Max of below)
Core [core-id] :Actual Freq (Mult.) C0% Halt(C1)% C3 % C6 %
Temp VCore
Core 1 [0]: 3486.94 (34.96x) 1.81 0.542 1 96.1
45 1.1337
Core 2 [1]: 3488.61 (34.98x) 1.99 2.72 2.67 92
44 1.1343
Core 3 [2]: 3491.06 (35.00x) 2.4 0 1 97.2
44 1.1342
Core 4 [3]: 3489.42 (34.98x) 1.13 0.854 1.13 96.5
44 1.1375


thanks
