Two comments:
1) I don't see how passing a single region is any help. I'd rather like to see
a device tree like table structure
You'd get one variable for len of the table, one with the contents. So for a
universal reserved region specifier you'd get:
<u64 base><u64 len>
Then have len=2 and put data in the table:
<u64 base1><u64 len1><u64 base2><u64 len2>
That way we'd get 2 entries and the chance to enhance them later on. In fact,
it might even make sense to pass the whole table in such a form. That way qemu
generates all of the e820 tables and we can declare whatever we want. Just add
a type field in the table.
I am fine with having QEMU build the e820 tables completely if there is
a consensus to take that path.
2) Please inline patches. They showed up as attachments here, making them
really hard to comment on.
Sorry Thunderbug doesn't do that well, but they should be attached as
txt?
Cheers,
Jes
