[Qemu-devel] [RFC 0/8] Remove old_portio usage

[Hervé Poussineau]

These proposed patches aim at removing the .old_portio member of
MemoryRegionOps structure, and replacing their usage by .read/.write
handlers.

Patches 2 to 6 are already ready to be committed.
However, patches 7 and 8 depend of patch 1, where a better solution
needs to be found.

That way, faked I/O address space can be removed from architectures
which don't have it (MIPS, PowerPC...), and commits like
a178274efabcbbc5d44805b51def874e47051325 ("PPC: pseries: Remove hack
for PIO window") can be reapplied.

Hervé Poussineau (8):
  pc: disable bochs bios debug ports (do not apply!)
  xen_platform: do not use old_portio-style callbacks
  uhci: do not use old_portio-style callbacks
  acpi-piix4: do not use old_portio-style callbacks
  vga/qxl: do not use portio_list_init/portio_list_add
  isa: use memory regions instead of portio_list_* functions
  ioport: remove now useless portio_list_* functions
  memory: remove old_portio-style callbacks support
