[Qemu-devel] [PATCH 00/16] isa_register_portio_list, v2

From: Richard Henderson
Subject: [Qemu-devel] [PATCH 00/16] isa_register_portio_list, v2
Date: Tue, 23 Aug 2011 17:13:39 -0700

The problem that malc saw with sb16 was a major think-o on my part
with the whole interface.  We can't re-use the const sub-arrays of
the original MemoryRegionPortio array because they have the wrong
offset for the MemoryRegion to which it is attached -- the lookup
in find_portio fails.  We must adjust the offsets of the old_portio
array to be based against the MemoryRegion.

Which means we can easily eliminate the major complaint that came
with the previous round of comments -- the double PORTIO_END_OF_LIST
and the explicit marking of the ranges.  All we require of users
is that the array be sorted by offset.

The entire patch set is at

  git://repo.or.cz/qemu/rth.git mem-api-isa

and is of course based on

  git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git memory/master

Avi, the first two patches are fixes for compile errors in your
tree.  They probably ought to be squashed when next you rebase.

Malc, I tested sb16 vs the xtc-play you provided.  However I failed
to test the gus changes; the xtc-play program could not recognize
the device with "--device gus" before or after the patch set.
Should I be using another set of command-line options for that?
