As promised earlier this week some new stuff for the lovers of the
bleeding edge is online. If I don't hit problems after a few days
(everything seems fine in the machines I have tested this on) I'll move
all this stuff off the edge and into the core of the planet :-)
- new Planet CCRMA kernel: 2.4.20-12.ll.acpi
lowest latency, may have hiccups with hardware that depends on RedHat
specific kernel patches.
. based on 2.4.21-rc7 (very up to date :-)
. capabilities, low latency, preemptible kernel patches
. full acpi
. HZ=1000
. alsa rtc patch
. drm updates from the RedHat kernel (provides newer drm version)
. use dma when extracting audio from cdroms (untested)
- new RedHat capabilities kernel: 2.4.20-18.1.caps
partial low latency patch but not so bad - the advantage is that it is
the same as the RedHat kernel (should work on all machines where you
managed to install RedHat).
. same exact kernel as the latest RedHat update (2.4.20-18.x)
. plus capabilities
. plus drm low latency patches
. plus alsa rtc patch
[BTW: the new kernels are compiled on 7.2 (for 7.2/7.3), 8.0 and 9 so
there should be less issues with building extra kernel modules]
- new alsa: 0.9.4-1.cvs: the latest and greatest, many bugs fixed, new
bugs created (I'm sure)!
- new jack: 0.72.0-1
. installs a mount point for /var/lib/jack/tmp in /etc/fstab and
mounts it at install time. Helps with low latency when /tmp is in a
journalled filesystem.
To install add (temporarily) these entries to your /etc/apt/sources.list
and do an "apt-get update" (beware of broken lines due to mailer
wrapping):
RedHat 7.2:
rpm http://www-ccrma.stanford.edu/mirrors/planetccrma/apt
redhat/7.2/en/i386 planetedge
rpm http://www-ccrma.stanford.edu/mirrors/planetccrma/apt
redhat/7.x/en/i386 planetedge
RedHat 7.3:
rpm http://www-ccrma.stanford.edu/mirrors/planetccrma/apt
redhat/7.3/en/i386 planetedge
rpm http://www-ccrma.stanford.edu/mirrors/planetccrma/apt
redhat/7.x/en/i386 planetedge
RedHat 8.0
rpm http://www-ccrma.stanford.edu/mirrors/planetccrma/apt
redhat/8.0/en/i386 planetedge
RedHat 9:
rpm http://www-ccrma.stanford.edu/mirrors/planetccrma/apt
redhat/9/en/i386 planetedge
Installing the Planet CCRMA kernel:
apt-get install planetccrma-core
apt-get install planetccrma-core-smp
Installing the RedHat kernel:
apt-get install planetccrma-core-redhat
apt-get install planetccrma-core-smp-redhat
Installing the newer jack:
apt-get install jack-audio-connection-kit
A dist-ugprade should bring in the new alsa...
Enjoy and let me know how it goes!
