I am interested in porting dom0 to an RTOS kernel. Could someone tell me if this is even feasible? Thanks, Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

There were some talks about real-time+xen at the last summit, and one at the 2009 summit too; they migth be a good starting point.

You just need to support PCI drivers, ACPI, IOAPIC, IRQ, MSI/MSI-X and naturally the hypercalls. Then you also need to support booting the kernel from protected mode and parsing the DIRECTMAP_P2M array for your MMU code. Ah, and be able to work with events (which is an IRQ mechanism for PV guests). Oh, and packages the RTOS kernel in an ELF format. I think that covers it. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
