I'm trying to get my Xen Dom0 distributing the irqs in an smp enviroment. As far as I know there are 2 Options:
- Use irqbalance
- Configure the kernel without cpu hotplug support
My System is Debian Squeeze, Xen 4.0.4, Kernel 3.2.31.
My Problem is:
- irqbalance segfaults due to a changed /proc/irq* layout or irq0 missing (this seems to be a very old bug existing since Lenny)
- To configure a kernel without cpu hotplug support you must disable cpu powermanagement which seems to be impossible through the standard wys (make config / make menuconfig) - the option CONFIG_PM simply defaults to "Y".
Any idea anyone on how to get a debian dom0 kernel with a proper irq distribution?
