I'm running my Gentoo as a DAW (on jack). My memlock limits are set quite high due to the requirements of jack and ardour6. the pipewire was silently introduced into my system as a gnome-shell dependency. It installs a file into the /etc/security/limits.d that clamps memlock at 256K - far too low for my DAW. I spend a couple of days searching why I'm memlock limited all of a sudden. I think the file should have this line commented: 1000:60000 - memlock 256 It is based on userids and overrides the traditional approach to have the member of @audio or @realtime memlock unlimited. i don't run pipewire as a pulseaudio/jack replacement. It was just pulled in as the dependency. The warning in the ebuild should alert users to enable it if needs to, from my PoV
I'm sorry to hear about that. In my testing the sys-auth/realtime-base seemed to take precedence, so I assumed it will be okay. I will be retesting this once more but in the meantime you can either set INSTALL_MASK="/etc/security/limits.d/40-pipewire.conf" in make.conf or use package.env to set INSTALL_MASK="/etc/security/limits.d" on specifically media-video/pipewire.
Turns out I was probably using the realtime early on, and by the time the limits.d/ file was made things were pretty hectic, so it might have slipped my mind to double check if @realtime can still override it. Turns out - UID range is probably stronger match than any @<group> and will take precedence disregarding the lexicographical order of limits.d/ files. As such this is the best solution, I could come up with (i.e. replace 1000:6000 UID range with * for default marker, which can be overridden by @realtime): * - memlock 256 If no one voices any objections in this bug, I'll try to get that included in one of the future ebuilds.
Seems to work fine for me
