Re: [Xen-ia64-devel] CONFIG_DOMAIN0_CONTIGUOUS in domain.c

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

Hi. 

I think that construct_dom0() is broken for CONFIG_DOMAIN0_CONTIGUOUS.
I had to modify it heavily to boot dom0 with P2M/VP model.

For example
construct_dom0()
    ...
    memcpy(__va(pinitrd_start),initrd_start,initrd_len);
    This memcpy() assumes p==m.


I thought that CONFIG_DOMAIN0_CONTIGUOUS option was introduced
at the eary develpment stage and it remained just because
no one removed it. However I don't know its history.

thanks.
