We are pleased to announce the 2.6.24.7-rt8 tree, which can be downloaded from the location: http://rt.et.redhat.com/download/ Information on the RT patch can be found at: http://rt.wiki.kernel.org/index.php/Main_Page Changes since 2.6.24.7-rt7 - Read Write locks with multiple readers (Steven Rostedt) The previous versions of the RT tree would serialize the RW locks for all readers to allow for priority inheritance to take place. This change allows for multiple readers but still maintain priority inheritance. The number of readers that can hold a lock at any time may be limited by sysctl kernel.rwlocks_reader_limit Setting this to <= 0 will give allow for any number of readers. The default is set to NR_CPUS. ** Note: I made this change separate to allow for easy testing in case bugs have been introduced by this change. to build a 2.6.24.7-rt8 tree, the following patches should be applied: http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.24.tar.bz2 http://kernel.org/pub/linux/kernel/v2.6/patch-2.6.24.7.bz2 http://rt.et.redhat.com/download/patch-2.6.24.7-rt8.bz2 And like always, my RT version of Matt Mackall's ketchup will get this for you nicely: http://people.redhat.com/srostedt/rt/tools/ketchup-0.9.8-rt3 The broken out patches are also available. -- Steve -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
