| |
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).
