[Qemu-devel] [PULL 00/14] Memory API conversion batch 9: ISA

[Qemu-devel] [PULL 00/14] Memory API conversion batch 9: ISA

[Avi Kivity]

Please pull from

   git://github.com/avikivity/qemu.git memory/batch

This is the delayed ISA conversion series, now hopefully working across the
board.

Avi Kivity (4):
  mips_malta: move i8259 initialization after piix4 initialization
  mips_jazz: initialize i8259 after the ISA bus
  mips_r4k: initialize i8259 after the ISA bus
  ppc_prep: initialize i8259 after the ISA bus

Richard Henderson (10):
  pci: add pci_address_space_io()
  isa: Pass i/o address space to isa_bus_new
  isa: add isa_register_ioport()
  pc: Re-order pc_init1 to initialize the ISA bus before ISA devices
  cs4231a: Convert to MemoryRegion
  i8254: Convert to MemoryRegion
  i8259: Convert to MemoryRegion
  pckbd: Convert to MemoryRegion
  serial: Convert serial_isa_initfn to MemoryRegion
  fdc: Convert isabus_fdc_init1 to MemoryRegion

[Qemu-devel] [PATCH 07/14] mips_malta: move i8259 initialization after piix4 initialization

[Avi Kivity]

i8259 is an ISA device (or at least, depends on the ISA infrastructure to
register its ioport); and the ISA bus is supplied by piix4.  Later patches
make this dependency explicit.

Use qemu_irq_proxy() to stop the cycle by adding an extra layer of
indirection.

[Avi Kivity]

From: Richard Henderson <rth@twiddle.net>

The only non-obvious part is pic_poll_read which used
"addr1 >> 7" to detect whether one referred to either
the master or slave PIC.  Instead, test this directly.

[Qemu-devel] [PATCH 14/14] fdc: Convert isabus_fdc_init1 to MemoryRegion

[Avi Kivity]

From: Richard Henderson <rth@twiddle.net>

This requires some amount of hoop-jumping, so that we don't
inadvertently claim port 0x3f6, which is used by ISA IDE.

The sysbus initialization path is as yet unconverted.
