...to include support for booting a (b)zImage via a Real-Mode trampoline and very basic BIOS interupt services. I think that I may have this working to some level as I have put some raw serial outputs in the interrupt service routine and I'm getting hits on IRQs 0x10, 0x15 and 0x16. I then hacked __putstr() in arch/x86/boot/compressed/misc.c to output to the serial port rather than video memory but got no additional output so it looks like I'm not getting to the point of kernel decompression But, I really don't think this is the way I want to do it - U-Boot has already put the CPU into prot...

Hi All, I am not very familiar with xen details. Now I am thinking of building two privilged domain(domain 0 not driver domain) at boot time. The other question is that wether it is possible to create another domain 0 by domain-builder running in domain0? Does it make sense when domain 0 is shut down unexpectedly another domain 0 can run at once. Maybe it is absurd. I am looking forwards

Is there any real user for this vIRQ? I''m asking because, while debugging a problem that required to add some printk()s that could temporarily issue at a high rate, I ran into the situation that this extra output prevented guest/dom0 boot from making any progress. As I then realized this was due to the tasklet_schedule() called from inside the console handling code, which resulted in
