[Qemu-devel] [seabios patch 0/5] dynamic pci i/o windows

[Gerd Hoffmann]

  Hi,

This patch series makes the PCI I/O windows runtime-configurable via
qemu firmware config interface.  Main advantage is that we can size and
shuffle around the PCI i/O windows according to the amount of memory the
virtual machine has.  We don't need a hole for 64bit PCI bars, we can
just map them above the main memory.  The hole for 32bit PCI bars can be
enlarged for guests with less than 3.5 GB of memory.

Oh, and the pci device initialization fix is there too ;)

cheers,
  Gerd
