[Qemu-devel] [RFC v4 00/58] Memory API

[Avi Kivity]

New in this version:
  MemoryRegionOps gained .old_mmio and .old_portio members, which allow
  reusing old-style callbacks with the new API.  All uses were converted,
  except for eepro100.c, which uses the same MemoryRegionOps for both
  portio and mmio.  Some intermediate patches do introduce dispatching
  callbacks, but they are removed later.

Caveats:
- some devices still grab a global memory region instead of inheriting
  it from their bus.  Seen in the code as #include "exec-memory.h"

Avi Kivity (58):
  Hierarchical memory region API
  memory: implement dirty tracking
  memory: merge adjacent segments of a single memory region
  Internal interfaces for memory API
  memory: abstract address space operations
  memory: rename MemoryRegion::has_ram_addr to ::terminates
  memory: late initialization of ram_addr
  memory:  I/O address space support
  memory: add backward compatibility for old portio registration
  memory: add backward compatibility for old mmio registration
  memory: add ioeventfd support
  exec.c: initialize memory map
  ioport: register ranges by byte aligned addresses always
  pc: grab system_memory
  pc: convert pc_memory_init() to memory API
  pc: move global memory map out of pc_init1() and into its callers
  pci: pass address space to pci bus when created
  pci: add MemoryRegion based BAR management API
  sysbus: add MemoryRegion based memory management API
  usb-ohci: convert to MemoryRegion
  pci: add API to get a BAR's mapped address
  vmsvga: don't remember pci BAR address in callback any more
  vga: convert vga and its derivatives to the memory API
  cirrus: simplify mmio BAR access functions
  cirrus: simplify bitblt BAR access functions
  cirrus: simplify vga window mmio access functions
  vga: simplify vga window mmio access functions
  cirrus: simplify linear framebuffer access functions
  Integrate I/O memory regions into qemu
  exec.c: fix initialization of system I/O memory region
  pci: pass I/O address space to new PCI bus
  pci: allow I/O BARs to be registered with pci_register_bar_region()
