I re-read this thread and I am not sure I understand why we can't keep
host's RSDP descriptor. We are not mapping dom0 memory 1:1 (right?) so
we can place our versions of RSDT/XSDT at the address that the
descriptor points to.
Unless that address is beyond dom0 memory allocation so that could be a
problem I guess.
Also eventually we may want to add tables, not just remove some,
and then there may not be enough space at the original location.
Plus I think nothing precludes the XSDT living below 1Mb, and then
we're back into the same problems discussed in another branch of
this thread.
Yes, that is a problem.
I guess we will need to do something in Linux to override descriptor
search. There is already some cruft for this but it appears to be
kexec-specific.
