The latest version of rt-tests is now available as a tarball from: http://www.kernel.org/pub/linux//kernel/people/clrkwllms/rt-tests/rt-tests-0.63.tar.bz2 Also available in my git repo: git://git.kernel.org/pub/scm/linux/kernel/git/clrkwllms/rt-tests.git under tag v0.63 This version includes a new option: --numa, which is a counterpart to the recently introduced --smp option. The --smp option is a shorthand for: -t -a -n, meaning that one measurement thread is created per active CPU and is affined to that cpu and that clock_nanosleep is used for measurements. The --numa option does the same options as --smp, but also makes calls into libnuma to ensure that measurement threads are always bound to the memory node that is local to it's cpu (avoiding cross-node memory references). Each measurement thread's stack and major data structures are allocated from the local memory node. Note that to actually use --numa mode, you must pass NUMA=1 to the make build command: $ make NUMA=1 This is for all you embedded guys that could care less about NUMA :) Other changes from previous releases are that the hwlatdetect test has been moved to the python site-library (so that other tests can import it) and then symlinked to /usr/bin/hwlatdetect. Also, copyright messages have been updated in the source files (thanks Uwe). Clark
