Hi Maintainers, Recently we faced an cpu online issue with maxcpus= parameter.
We want to have 4 cpus onlined at bootup, test 3.8.13-stable on an 72 cpus env with maxcpus=4, I found more cpus than 4 are onlined. It's the udev scripts make them onlined. But below script exist for a long time. ACTION=="add", KERNEL=="cpu[0-9]*", RUN+="/bin/bash -c 'echo 1 > /sys/devices/system/cpu/%k/online'"
maxcpu= parameter didn't take effect, so is this a kernel bug? Or that script should be removed?
Btw: 2.6.39 works fine, I checked udev log, seems CPU ADD event is only sent for 4cpus.
Why the difference between 2.6.39 and 3.8.13? thanks zduan -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
