[Qemu-devel] [PATCH v2 00/21] q35 qemu support

[Jason Baron <jbaron@redhat.com>]

Hi,

Qemu bits for q35 support, I'm posting the seabios changes separately. The
patches require '-M pc_q35' and -L 'seabios dir with q35 changes' on the
qemu command line. Hopefully, we can make it the default for x86 at some future
point when we feel comfortable with it.

Since q35 patches have been posted before I've tried to keep the authorship as
clear as possible.

The current patches have been tested with basic install testing and memory testing
on f16, f17, windows 7 and windows 8. They can be run on the various BSD flavors
by adding a 'piix4-ide' device to the pci bus. ie: -device piix4-ide.

I've dropped the ahci migration bits, which means q35 is not migratable at the
moment. I simply haven't had time to make them more complete yet.

I'm hoping that we'll come to some agreement on the minimal functionality
required for q35 to be merged.

Git trees:

git://github.com/jibaron/q35-qemu.git
git://github.com/jibaron/q35-seabios.git

todo:

-add ahci migration back (need to cover more fields, but basically works)
-add base addr for hpet in LPC device (for osx per agraf)
-convert hotplug to use MemoryRegionPortio for hotplug (need an IsaDevice?)

Thanks,

-Jason

Changes from v1:
 -Updated end of low mem from 0xe0000000 -> 0xb0000000 (Gerd Hoffmann)

 -style/various cleanups
 -introduced IF_AHCI
 -introduced mach_if
 -split dsdt out of bios, now passed for piix4 as well (Paolo, Gerd)
