Thread-topic: Questions about VIRT_BASE and ELF_PADDR_OFFSET in __xen_guest
Keir,
I was looking at your changeset:
http://xenbits.xensource.com/xen-unstable.hg?cs=dbe396fd6fd8
I am finding that by making VIRT_BASE=0x0 is causing the builder to seg
fault. The same thing happens when VIRT_BASE and ELF_PADDR_OFFSET is set
to 0. I don't understand why dsi->elf_paddr_offset is being set to
VIRT_BASE and then overridden with ELF_PADDR_OFFSET if it is set. Does
ELF_PADDR_OFFSET have any real use? Does it correlate with anything in
the ELF program header? I am a little confused here :-), so could you
please explain.
Thanks,
Aravindh Puthiyaparambil
