[Qemu-devel] [PATCH v3 0/4] pc: pass pci window data to guests

[Michael S. Tsirkin]

This makes it possible for bios to load pci window
data from host.

This makes it possible for host to make sure
setup matches hardware exactly.
This will also make it easier to add more chipsets
down the road.

Ranges are passed within a generic GuestInfo
structure, can add more fields of interest
to Guests in the future.

Note: this is on top of my PCI branch,
if no one objects I'd like to merge it through
there as there are some trivial dependencies on that.

Changes from v1:
    - fix v1.5-v1.6 migration compatibility
    - address Peter Maydell's comments on range.h
    - make addresses a bit smaller, compatible to what seabios does at the
      moment. We can increase the windows, carefully, at a later time.

Changes from v2:
    - document alignment requirements for 32 bit as suggested by Gerd
    - align 64 bit windows as suggested by Gerd
    - tweak field name for 1.5 compat support
    - smash compat patch into main fw cfg patch,
      avoid bisect breakage
    - add patch to reduce compat code duplication
Michael S. Tsirkin (5):
  range: add Range structure
  pci: store PCI hole ranges in guestinfo structure
  pc: pass PCI hole ranges to Guests
  pc: add 1.6 compat type
  pc: pci-info add compat support
