What is the exact difference between kernel-rt and the kernel-default package?
Technically speaking, the config options: http://rafb.net/p/ciyR0n64.html
While the config options do play a role, the bigger difference is an additional 1.6 MB patch[1] that gets applied to the -rt tree that changes the latency behaviors in a lot of areas. With a few exceptions, most spinlocks become sleeping locks. It targets low latency rather than overall throughput. Realtime simulations use it, so the behavior of the system is more predictable. I've also seen favorable reports from users doing audio/video work as well. In general, though, it's not really what you want for your default system. It's the only kernel we ship where the source tree differs between flavors. In the long term, we hope to eliminate that distinction, but there are too many parts of -rt that can't be built conditionally and we don't want to suck it all in for ever flavor. - -Jeff [1] http://www.kernel.org/pub/linux/kernel/projects/rt/ - Note: This patch is different than the one in the CVS repo since we have to port it to our kernel source. However, for demonstration purposes, it's sufficient. The changes were pretty minor. - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.4-svn0 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFHEkAALPWxlyuTD7IRAtrRAKCKBCYNH0L01ugSeH2r+zfa5nWKLACfXpJk ijgAXT+xf/Y0bGlDlc7jO4s= =ezbf -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
