Hello Simon, > From the openPOWERLINK documentation (linux-x86.txt): Thanks for the answer, but I already knew this documentation :) I have applied the described steps, and I think they work as expected. My box has two cores, and I can see in htop that nothing is running on the second cpu, except my tasks which I start with the tool taskset. Also in /proc/interrupts I can see that all IRQs are handled by the first cpu, except the POWERLINK-related ones, which are handled by the second cpu. So as far as I know everything is configured as expected, however, I still see non-satisfying results with kernel 3.2-rt. I have uploaded two images with measurements results for easy comparison: 2.6.33-rt: http://imageshack.us/photo/my-images/818/q4de.png/ 3.2-rt: http://imageshack.us/photo/my-images/845/nqdw.png/ Both images show the reaction of the openPOWERLINK-stack on different workloads on the two kernels. Any further hints on how to improve the 3.2-rt results are greatly appreciated :) kind regards, Wolfgang Wallner -- 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
