[Qemu-ppc] [PATCH v3 0/8] qdev'ify PReP PCI host bridge and add PCI-to-I

From: Andreas Färber
Subject: [Qemu-ppc] [PATCH v3 0/8] qdev'ify PReP PCI host bridge and add PCI-to-ISA bridge
Date: Fri, 13 Jan 2012 04:09:20 +0100


Here's an updated initial qdev'ification series for PReP, as prerequisite
for Anthony's second QOM series.

As stated before, this is NOT a complete conversion of all PReP devices
and of all those shared with x86. Please comment on what's there, not on
what may be done, too. I'm sitting on these patches for over a year now,
so let's start getting some of it merged so that we can move on with QOM
and get some of the design issues fixed that kept the pc87312 Super I/O
and 40P machine from getting merged in the first place!


Changes since v2:
* Simplify I/O byte swaps.
* Convert I/O from old_mmio to MemoryRegion ops.
* Drop pci_prep_init() and instantiate the PCI host bridge in the machine,
  reintroducing PREPPCIState extension.
* Connect IRQs via qdev after instantiating. Suggested by Alex.
* Add a rebased PCI-to-ISA-bridge from the 40P series on top, to show why
  some suggestions from v2 and IRC don't work out.
  * Merge fix-up by Hervé: Add indirection for late-connected out[0] IRQ.
  * Add VMState for i82374 and i82378.
  * From i82378 drop the I/O address translation duplicated from the board.
  * Rebase i82378 onto Memory API.
* Add new patch from Hervé to wire up the PCI-to-ISA bridge for 'prep'.

Changes since v1:
* Use the new .vendor_id etc. in PCIDeviceInfo
* Rename from PRePPCI to Raven, adopt naming scheme from i440FX
* Rebase onto multiple Memory API conversions
* Split into PCIDevice and SysBus patches, leave out PREPPCIState changes
