Hi to all,
how are you? It seems i don't write since many months in the forum.
Maybe it'a good sign, maybe i 'm trying to understand something and resolve problems from myself...maybe
I have started to produce music from my own with my arch linux distro. The system is always updated and goes quite well.
I don't even installed a DAW, perhaps, cause i have to resolve my latency problem. I made many tests and i checked with jack_iodelay. i have yet 1 sec delay so i decided to improve my pro audio with all the tweaks provided here: https://wiki.archlinux.org/title/Professional_audio
Actually i have implemented this:
Pro audio tweaks
Gab is part of realtime group
Installed realtime privilegies
/etc/security/limits.d
99-realtime-privileges.conf
/etc/security/limits.conf
@pipewire - memlock 4194304
@pipewire - nice -19
@pipewire - rtprio 95
Now i'm starting to configure Cpu frequency scaling.
I'm started from here: https://wiki.archlinux.org/title/CPU_frequency_scaling
I have installed cpupower without Gui. And set as a service at startup. My user is in the wheel group.
This is my frequency info:
analyzing CPU 3:
driver: intel_pstate
CPUs which run at the same hardware frequency: 3
CPUs which need to have their frequency coordinated by software: 3
maximum transition latency: Cannot determine or is not supported.
hardware limits: 400 MHz - 3.00 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 400 MHz and 3.00 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency: Unable to call hardware
current CPU frequency: 673 MHz (asserted by call to kernel)
boost state support:
Supported: yes
Active: yes
I'm using pstate intel driver
This is instead the cpupower conf file in /etc/default/cpupower
# Define CPUs governor
# valid governors: ondemand, performance, powersave, conservative, userspace.
#governor='ondemand'
# Limit frequency range
# Valid suffixes: Hz, kHz (default), MHz, GHz, THz
#min_freq="2.25GHz"
#max_freq="3GHz"
# Specific frequency to be set.
# Requires userspace governor to be available.
# Do not set governor field if you use this one.
#freq=
# Utilizes cores in one processor package/socket first before processes are
# scheduled to other processor packages/sockets.
# See man (1) CPUPOWER-SET for additional details.
#mc_scheduler=
# Utilizes thread siblings of one processor core first before processes are
# scheduled to other cores. See man (1) CPUPOWER-SET for additional details.
#smp_scheduler=
# Sets a register on supported Intel processore which allows software to convey
# its policy for the relative importance of performance versus energy savings to
# the processor. See man (1) CPUPOWER-SET for additional details.
#perf_bias=
# vim:set ts=2 sw=2 ft=sh et:
I'd like to have best performance to reduce latency. I know for now all values are commented so are not running.
Now what i'd like to know is:
1) What frequency is suggested to insert?
2) I have to configure the scaling governor inside the conf file, correct? If i 'd like to have performance only when i started music and daws software how can i write a shell script to reach this goal? I have no idea how to write shell script to enahnce performance only in this case. Or maybe there are different solutions?
After reaching this first goal i will open another thread about the real time kernel patchset...but not in this post
Many thanks
Bye
Gabriele

Don't change the frequencies, switch the scaling governor to performance instead of powersave, will do the correct thing for the intended purpose, and the powerdraw should not increase that much while idle. if you wanted to write a wrapper script for that that to change this on the fly you can just run the appropriate cpupower set-frequency -g performance command before and after running the application e.g.
#! /bin/sh
sudo cpupower frequency-set -g performance
$1
sudo cpupower frequency-set -g powersave
and for simplification purposes you'd probably want to configure these two commands to be ran passwordless.
That said 1 sec delay sounds too high and not correct without having to do any tweaks however. In which context and with which tools are you asserting that amount of a delay? Which audio cards/speakers/headphones are involved? Note if you are using something with wireless you can forget low latency immediately. Which CPU is this?

Hi!
Thanks so much for your response
i can give you more details:
I have the last kernel available (i don't launch pacman -Syu since 1 week so i hop ).
Using pipewire with wireplumber and qpwgraph. Xmonad is my window manager and installed axarva mod that uses xmonad, with tint2conf, eww, rofi and screenlock.
This is my archey output:

if i launch
top
i have 95% of my cpu free!
Then to make music now i'm using Carla rack with lv2 or vst pugins. I didn't yet installed a Daw cause i want to solve my latency problem first. I use only peripherals with cables, no wireless.
I haven't used hearphones only speakers connected to internal sound card with a normal green jack.
With qpwgraph i change the routes of soundcard.
I'm using an electric guitar with focusrite and a midi keyboard with carla and odin vst for example or many other vst or lv2 plugins (calf plugins and many others).
Last but not least these are my logs with
jack_iodealy
.
I made some tests without and within the scale governor on performance.
