I don't run pf-sources, but I run a BFS-patched gentoo-sources. One of |
| 16 |
the reasons I use it is because of its support for the SCHED_ISO process |
| 17 |
priority, which is important for audio applications. Otherwise, I would |
| 18 |
need to use a realtime-linux kernel, which is total overkill and I don't |
| 19 |
want to reboot into a different kernel just for an audio session. Also, |
| 20 |
SCHED_ISO works for normal users so I don't have to launch stuff like |
| 21 |
jack-audio as root. |
| 22 |
|
| 23 |
Another reason I use it is because my system becomes a bit more |
| 24 |
responsive with BFS (meaning the GUI - I use KDE). You can do that with |
| 25 |
the mainline scheduler too, but it's not automatic; you have to set up |
| 26 |
the cgroups feature (creating different cgroups for different |
| 27 |
applications), and I never bothered. It's up to the distro to provide a |
| 28 |
cgroups setup, but I don't know whether Gentoo or any other distro |
| 29 |
actually does it. My guess is not. Without a setup, users have to |
| 30 |
launch their applications from the terminal, which is kind of stupid. |
| 31 |
Launching them from the GUI will place them all in the same cgroup. |

So BFS it is for me :-) |
