[Xen-devel] Re: Need some help about the build xen.efi

[liang tang <liang.tang@xxxxxxxxxx>]

Hi,konrad,Jan
Thank you very much for your help, now i can build xen.efi and i use 
basevideo and cfg file
kernel=vmlinuz-3.0.0+
ramdisk=initramfs-3.0.0+.img

after run xen.efi I got debug message "tangl debug xen loader debug 1" 
don't got the "tangl debug xen loader debug 2" .
    PrintStr(L"tangl debug xen loader debug 1\n");
    status = efi_bs->ExitBootServices(ImageHandle, map_key);
    if ( EFI_ERROR(status) )
        PrintErrMesg(L"Cannot exit boot services", status);

    PrintStr(L"tangl debug xen loader debug 2\n");

if I mark //status = efi_bs->ExitBootServices(ImageHandle, map_key); xen 
will halt in here load the domain 0.

    if ( (rc = bzimage_parse(image_base, &image_start, &image_len)) != 0 )
        return rc;
is configure file ok? any idea about that?
thank you very much!
