...d a lot of guests, as our smallest hardware has 32GiB ram, and our median guest has 256MiB ram. we followed http://lists.xensource.com/archives/html/xen-devel/2010-04/msg01537.html and changed NR_DYNAMIC_IRQS in arch/x86/include/asm/irq_vectors.h to 2048. we changed the .config like so: CONFIG_SPARSE_IRQ=n then we applied the following patch to arch/x86/include/asm/irq_vectors.h: --- ./linux-2.6-pvops.git/arch/x86/include/asm/irq_vectors.h.old 2010-08-11 15:40:53.000000000 +0000 +++ ./linux-2.6-pvops.git/arch/x86/include/asm/irq_vectors.h 2010-08-11 15:41:39.000000000 +0000 @@...

Gerry, thanks for you explanation. :) This should no longer be an issue, as arm64 uses CONFIG_SPARSE_IRQ and the number of interrupts is not limited in any form. My point was more that the device driver should not need to care about the interrupt number: it gets made up on the spot when the MSI is needed, and then it is only used to request the IRQ. This can be simplified into one interface at the de...

I''ve been trying for several days to get a xen dom0 booting as described on Boris Derzhavets blog. I have been able to boot Jeremy Fitzhardinge''s pv_ops kernel under xen, but my X server wouldn''t start so I''ve been trying to get Andrew Lyon''s rebased opensuse patches to work. I have asked for help in the freenode ##xen channel but they
