IA64 arch defines some more percpu events, like perfmon and MCA (Machine Check Abort), which can be categorized into VIRQ type since generated by xen just like virtual timer. Though I've not tidy up more types to be really added, this patch first gives chance. The way you've defined it makes it hard to add more base virqs (as that would shift the arch-specific virq numbers, which is unacceptable as they are visible to guests). How about doing as for hypercalls and define VIRQ_ARCH_0...VIRQ_ARCH_7 as virqs 16-23, say? -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
