I'm not familiar with Linux kernel internals, or how scaling_cur_freq is
implemented internally, but that doesn't look like a valid logic to me.
If it takes an IPI (or two, as the commit message suggests) to read the
core frequency, then make those IPIs. It doesn't matter how expensive it
is - if t
@arighi: Did you consider applying lowlatency settings to generic kernel
but keeping CONFIG_HZ=250?
I suspect, the majority of desktop usage issues (i.e. responsiveness)
would be solved by `preempt=full rcu_nocbs=all` being the default (or
whatever the equivalent boot options are). While keeping C
I have run a quick `7z b` benchmark on the lowlatency kernel with and
without `nohz_full` parameter, and the results are fairly close:
No `nohz_full` parameter:

> Note also, in my case, the CPU frequencies actually seem to be scaling
properly, it is just that they are not being reported properly via
"/sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq".
To be clear, I cannot be sure whether that was also the case in my
testing. I didn't test the actual
While testing locally, I have found this problem:

If this is indeed a valid bug and not something weirdly specific to my
system, I'd say `nohz_full` is non-functional.

Public bug reported:
With the lowlatency kernel, if I specify "nohz_full=1-15" boot parameter
then CPU frequency scaling doesn't work for the logical cores 1-15. That
is, only logical core 0 shows varying CPU frequency in its
/sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq file, all other

I couldn't find this in the benchmark description on Phoronix, so I'm
assuming the lowlatency kernel was booted with default parameters. Which
means CONFIG_NO_HZ_FULL basically had no effect. This is probably fair
for most users who won't specify `nohz_full` kernel parameter and will
observe the pe
