Hello fellow Archlinux users, I may be stuck with a little problem that has limited information available.
I use a Dell Inspiron 5570 laptop, with the processor Intel i7-8550U 1.8Ghz. This processor has turboboost up to 4Ghz.
$ sudo cpupower frequency-info
analyzing CPU 0:
driver: intel_pstate
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: Cannot determine or is not supported.
hardware limits: 400 MHz - 1.80 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 1.80 GHz and 1.80 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 1.80 GHz (asserted by call to kernel)
boost state support:
Supported: no
Active: no
$ cat /sys/devices/system/cpu/intel_pstate/no_turbo
1
$ su -c "echo 0 > /sys/devices/system/cpu/intel_pstate/no_turbo"
bash: line 0: echo: write error: Operation not permitted
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
performance
Turbo boost is enabled in the BIOS. What am I missing?

Dells have a knack for this, FWIW something that has been reported to be helping, shutdown, take out the battery for a few minutes, reinsert, recheck.

I removed the battery for 30 minutes and that unfortunately made no difference.

I disabled Turboboost in the BIOS, then booted into archlinux. I restarted Archlinux, went to the bios and enabled turboboost, and then booted back to Archlinux and that seems to have fixed the problem.
