[Qemu-devel] [PATCH V5 0/8] memory: unifiy ioport registration

[Julien Grall <julien.grall@citrix.com>]

This is the fifth version of patch series about ioport registration.
The fourth version was sent few months ago
(https://lists.gnu.org/archive/html/qemu-devel/2012-04/msg01396.html).

Some part of QEMU still use register_ioport* functions to register ioport.
These functions doesn't allow to use Memory Listener on it.

Modifications between V1 and V2:
   - Remove the use of get_system_io. Instead of use isa and pci IO
     address space.
   - Avoid allocation of PortioList. Use the different device
     structure.
   - Still remove register_ioport* (hw/dma.c, hw/apm.c,
     hw/acpi_piix4.c).
   - Use MemoryRegion when we have only a range of ioport.
   - For some functions, add IO address space as
     argument.
   - Add isa_address_space_io function

Modifications between V2 and V3:
   - Remove some register_ioport_* on hw/vt82c686.c.
   - Split smb ioport part in new patch.
   - Still replace MemoryRegion when we have only a range of ioport.
   - Fix read/write ioports prototype to  be compliant with memory callback.

Modifications between V3 and V4:
   - Fix compilation in hw/dma.c
   - Fix address conversion (hw/dma.c, hw/acpi_piix4.c) with MemorySection.
     Indeed the new version use offset from MemorySection start instead of 0.

Modifications between V4 and V4:
   - Rebase on qemu upstream.
   - Forget some ioport_register_* in acpi_piix4.c.
   - Register 0x3b0 - 0x3df range for cirrus instead of ioport by ioport.
