[Qemu-devel] [PATCH 00/10] PPC NewWorld fixery v4

[Alexander Graf]

I'm trying to get the PPC64 system emulation target working finally.
While doing so, I ran into several issues, most related to PCI this time.

This patchset fixes all the PCI config space access and PCI interrupt
mapping issues I've found on PPC64. Using this and a patched OpenBIOS
version, I can successfully access IDE devices and was booting a guest
into the shell from IDE using serial console.

To leverage this patch, you also need a few patches to OpenBIOS. I'll
present them to the OpenBIOS list, but in general getting patches into
Qemu is harder than getting them into OpenBIOS. So I want to wait for
the review process here first.

WARNING: This patchset is based on top of mst's rwhandler patches. You
         can find those here:

         git://git.kernel.org/pub/scm/linux/kernel/git/mst/qemu.git

v1 -> v2:

  - use decoding function for config space bits
  - merge config space data access functions
  - introduce encoding function for x86 style encodings
  - convert Uninorth to use config space decoder

v2 -> v3:

  - call pci_addr_to_devfn pci_addr_to_config_reg
  - split out debug fix
  - call convert functions config_addr instead of config_reg
  - no spaces between braces
  - dropped: Enable secondary cmd64x
  - new: Tell the guest about the time base frequency
  - new: Use macio IDE controller for Newworld
  - new: Get rid of segfaults in DBDMA emulation
  - new: Add USB per default on U3

v3 -> v4:

  - fix fgets warning
  - use self-contained config space data functions
  - use mst's rwhandler
  - move lspci output up
  - new: Fix large pages
  - new: Add timer when running KVM
