Public bug reported:
I have an HP laptop with Core i5-8300h and it almost doesn't use all-
core turbo after couple minutes after boot. When I run a single threaded
task, it maintains frequencies of 3.5-4 GHz, but as I run anything on
all cores the clock drops to rates near the base frequency of 2.3 GHz
(runs at 1.7-2.5Ghz). The first couple minutes after boot all cores run
on full multi-core boost frequency of 3.9 GHz if loaded. It can't be a
thermal issue as the temperature drops to about 55°C and the fans go
almost silent (much more quiet than under single-core load).
The issue was present on 18.04 and original 20.04, disappeared with some
update in 20.04 branch (the laptop would maintain 3.9 GHz turbo on all
cores) and now returned in 22.04 and 22.10 (I've tried various DE
flavors). Under the Windows the full multi-core turbo sustains for
indefinite time during non SIMD workloads.
Switching governors makes no difference. I've tried disabling
intel_pstate, turning thermald on or off, throttled and auto-cpufreq
custom daemons and nothing helped.
