Hi, Definitive numbers are hard to give since it's quite system specific, also most of the work on RT-Preempt have been to bring it inte mainline, so last stable is 2.6.33-rt<something>.
But the BKL is gone in linus 3.0 , and the really nice thing is that RT-Preempt gives nice performance on SMP systems and HT-Processors. osadl.org have a nice test farm with a varity of system and graphs , generally if youre 'lucky' and have hardware with 'nice' drivers ( which are the biggest offenders ), you 'should be able to get 10 - 20 u , now with a 'bad system youre running up agains 1 ms .... all of this is progressing. The biggest thing is that it's sneaking into mainline, and can give really good results on some systems, and it would be nice to run EMC on an unpatched kernel. For emc it's basicly an rt-api file and some makefile changes. / Lars Segerlund. 2011/6/9 Jon Elson <el...@pico-systems.com>: > Lars Segerlund wrote: >> Hi guys, >> >> A while ago ( se : >> http://permalink.gmane.org/gmane.linux.distributions.emc.devel/3470 ) >> , I asked about emc2 and RT-Preempt ... >> > Can you give some latency and jitter figures for this kernel patch? > > Thanks, > > Jon > > ------------------------------------------------------------------------------ > EditLive Enterprise is the world's most technically advanced content > authoring tool.
