[Qemu-devel] [PATCH 00/26] q35 chipset support for native pci express support

[Isaku Yamahata]

This patch series adds basic q35 chipset support for native pci express
support. Some bios related patches are still needed.
For those who want to try it, the following repo is avaiable.
(vgabios doesn't need patches, so use the upstream one)

git clone http://people.valinux.co.jp/~yamahata/qemu/q35/20110316/qemu
git clone http://people.valinux.co.jp/~yamahata/qemu/q35/20110316/seabios

Example:
qemu-system-x86_64 ... -M pc_q35 -acpitable 
'load_header,data=roms/seabios/src/q35-acpi-dsdt.aml


The motivation is to support newer hardware features because
piix chipset is very old.
Especially I have PCI express in mind and this is the basic infrastructure
for PCI express hot plug and PCI express native direct attach.
I can boot Linux with PCIe MMCONFIG with APIC mode pci interrupt routing.
I haven't tested other OSes.

The patch series consist as following

- Firstly, some PCI patches which introduce helper functions and so on.
- Then, PC initialization related patches which simplifies pc board
  initialization, pc_init1().
- Thirdly, factoring out the logics which are common to the existing
   piix and q35. ie. smram, pam and acpi logic.
- At last introduce q35 chipset emulator which is able to handle
  pci express natively.

Thanks,

Change from v7:
- heavily reorganized and improved.
- factoring out code duplication.
- improved irq routing fully.

Changes from split out piix specific part from pc emulator. V6
- rebased to 731c54f86988d3f28268f184fabfe9b2a32fb5d3
- PCIe MMCONFIG
- pci bridge related fixes
- chipset emulator works.
- IOAPIC patches

Changes from v5:
- rebased 0.11.0-rc0
- changed qemu_system_powerdown_register() to call
  qemu_system_shutdown_request() if qemu_system_shutdown() is called before
  registering.

Changes from v4:
- fix version number.
- rebased anthony's staging tree whose latest change set is
  62969268f876c547ee64da6d60e0f363e0f1df75

Changes from v3:
- move qemu_system_powerdown() in vl.c and more generic
  following the comment by Marcelo Tosatti <address@hidden>
  acpi.c: make qemu_system_powerdown() piix independent.
- define cmos_set_s3_resume_init() and cmos_set_s3_resume() in pc.c
  even if TARGET_I386 isn't defined following th ecommit by
  Paolo Bonzini <address@hidden>
  pc.c: remove a global variable, RTCState *rtc_state.
- minor compilation fixes

Changes from v2:
- clean up pc_pci_device_init() not to use unnecessary braces.

Changes from v1:
- make patches full bisectable
- typo s/allocte/allocate/
- some minor fixes
- dropped a merged patch
