Hi All, For those who are interested I have placed two new kernels (-lowlatency and -realtime) into my PPA: https://launchpad.net/~abogani/+archive/ppa
The -lowlatency kernel contains a more aggressive configuration to reduce latency than the -preempt one. But like -preempt it doesn't contain any code changes (so both start from the same -generic source tree). The -realtime kernel contains the upstream version of PREEMPT_RT patchset applied to a vanilla Linux kernel. The Ubuntu Archive already provides the linux-rt package but it uses the Karmic source tree as base for PREEMPT_RT patchset. The PPA also contains meta-packages so that after you have added PPA into your Ubuntu system a simple "sudo apt-get install linux-realtime" or "sudo apt-get install linux-lowlatency" will install what you need. There is also a recent copy of rt-tests for evaluation and comparison of all kernels and to better identify which meets your needs. I suggest following these simple rules: *) if you don't need a low latency system use -generic kernel *) If you need a low latency system please use -preempt kernel as a first choice (this reduces latency but doesn't sacrifice power saving features) from the Ubuntu archives directly from Ubuntu Kernel Team *) If you have an i386 system or -preempt isn't enough for your needs you should try the -lowlatency kernel present in my above-mentioned PPA. *) If -lowlatency also isn't enough you should try the -realtime kernel (like -lowlatency it is available through my PPA) Feel free to get in touch with me if you find these useful.
