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)

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 <mtosa...@redhat.com> 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 <bonz...@gnu.org> 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 Isaku Yamahata (26): pci: replace the magic, 256, for the maximum of slot pci: add opaque argument to pci_map_irq_fn pci: introduce pci_swizzle_map_irq_fn() for standardized interrupt pin swizzle pci: add accessor function to get irq levels piix_pci: eliminate PIIX3State::pci_irq_levels pci_bridge: add helper function to convert PCIBridge into PCIDevice pci/p2pbr: generic pci p2p bridge apb_pci: simplify apb_pci.c by using pci_p2pbr dec_pci: simplify dec_pci.c by using pci_p2pbr ide/ahci/ich: use qdev.reset ahci: add ide device initialization helper usb/uhci: generalize initialization usb/uhci: add ich9 usb uhci id's device ide: consolidate drive_get(IF_IDE) smbus_eeprom: consolidate smbus eeprom creation pc, pc_piix: split out allocating isa irqs pc, pc_piix: split out pc nic initialization ioapic: move ioapic_init() from pc_piix.c to pc.c pc/piix_pci: factor out smram/pam logic pc, i440fx: simply i440fx initialization acpi, acpi_piix: factor out PM_TMR logic acpi, acpi_piix: factor out PM1a EVT logic acpi, acpi_piix: factor out PM1_CNT logic acpi, acpi_piix: factor out GPE logic pci_ids: add intel 82801BA pci-to-pci bridge id and PCI_CLASS_SERIAL_SMBUS pc q35 based chipset emulator Makefile.objs | 2 +- Makefile.target | 3 +- hw/acpi.c | 197 ++++++++++++ hw/acpi.h | 68 ++++ hw/acpi_ich9.c | 314 +++++++++++++++++++ hw/acpi_ich9.h | 53 ++++ hw/acpi_piix4.c | 220 ++++---------- hw/apb_pci.c | 67 ++--- hw/bonito.c | 2 +- hw/dec_pci.c | 51 +--- hw/grackle_pci.c | 2 +- hw/gt64xxx.c | 2 +- hw/ide.h | 6 + hw/ide/ahci.c | 15 + hw/ide/core.c | 14 + hw/ide/ich.c | 9 +- hw/mips_fulong2e.c | 18 +- hw/mips_malta.c | 22 +-- hw/mips_r4k.c | 10 +- hw/pam.c | 128 ++++++++ hw/pam.h | 96 ++++++ hw/pc.c | 47 +++- hw/pc.h | 7 +- hw/pc_piix.c | 64 +---- hw/pc_q35.c | 359 +++++++++++++++++++++ hw/pci.c | 27 ++- hw/pci.h | 6 +- hw/pci_bridge.c | 6 + hw/pci_bridge.h | 1 + hw/pci_ids.h | 17 + hw/pci_internals.h | 2 +- hw/pci_p2pbr.c | 151 +++++++++ hw/pci_p2pbr.h | 61 ++++ hw/piix_pci.c | 117 +++----- hw/ppc4xx_pci.c | 2 +- hw/ppc_newworld.c | 11 +- hw/ppc_oldworld.c | 11 +- hw/ppc_prep.c | 10 +- hw/ppce500_pci.c | 2 +- hw/prep_pci.c | 2 +- hw/q35.c | 877 ++++++++++++++++++++++++++++++++++++++++++++++++++++ hw/q35.h | 271 ++++++++++++++++ hw/q35_smbus.c | 154 +++++++++ hw/sh_pci.c | 2 +- hw/smbus.h | 3 + hw/smbus_eeprom.c | 22 ++- hw/sun4u.c | 9 +- hw/unin_pci.c | 2 +- hw/usb-uhci.c | 93 +++--- hw/versatile_pci.c | 2 +- 50 files changed, 3116 insertions(+), 521 deletions(-) create mode 100644 hw/acpi_ich9.c create mode 100644 hw/acpi_ich9.h create mode 100644 hw/pam.c create mode 100644 hw/pam.h create mode 100644 hw/pc_q35.c create mode 100644 hw/pci_p2pbr.c create mode 100644 hw/pci_p2pbr.h create mode 100644 hw/q35.c create mode 100644 hw/q35.h create mode 100644 hw/q35_smbus.c
