As I worked for QNX I liked to provoke my Canadian coworkers with arguments like: RTLinux is able to swap - not bad for a hack ;-) http://groups.google.de/groups?selm=378b7d25%240%24199%40nntp1.ba.best.com&output=gplain > Just... an .mp3 player for a desktop environment?

When talking about hard realtime it's all about worst case considerations. Average does not count (then you are talking about *soft realtime* -> like multimedia apps, where only the quality counts). So you could only tell how long your compile lasts at *maximum* As I said before: the OS is only the foundation for realtime *systems* > > Summary: Linux + RTOS should never become VxWorks. > Yes, given that vxworks is more like a realtime executive (but this seems to change: only true when running without VxVMI? ) http://www.windriver.com/products/html/vxwks5x_ds.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
