[Xen-devel] about mini-os

["余上" <yusunn@xxxxxxxxx>]

Hi all ,

I find that it needs some hacks to run mini-os under xen-3.2 ,
followings are what I have done:

1, mini-os/arch/x86/x86_32.S , change the __xen_guest config :
from
        .ascii  ",VIRT_BASE=0x0" /* &_text from minios_x86_32.lds */
        .ascii  ",ELF_PADDR_OFFSET=0x0"
to
        .ascii  ",VIRT_BASE=0x0C0000000" /* &_text from minios_x86_32.lds */
        .ascii  ",ELF_PADDR_OFFSET=0x0C0000000"
because if I don't change VIRT_BASE xen will report "Initial loading
isn't allowed to lowest 1GB of memory"

2, mini-os/arch/x86/minios-x86_32.lds
from
  . = 0x0;
to
  . = 0x0C0000000;

so far , I can run mini-os to the banner and got a page fault:
Bootstraping ...
Xen Minimal OS!
Page fault at linear address 15555c08, eip c000cf61, code 0
(XEN) Domain 0 crashed

any idea ? Thank you very much
yushang
