From: miaoyubo <miaoy...@huawei.com> Currently pxb-pcie is not supported by arm and only one main host bridge is described in acpi tables, which means it is not impossible to present different io numas for different devices. This series of patches make arm to support PXB-PCIE.
Users can configure pxb-pcie with certain numa, Example command is: -device pxb-pcie,id=pci.7,bus_nr=128,numa_node=0,bus=pcie.0,addr=0x9 Since devices could not be plugged into pxb-pcie directly, one pcie-root-port is auto plugged into the pxb, therefore, the devices could be plugged into pxb-pcie. With the patches,io numa could be presented to the guest by define a pxb-pcie with the numa and plug the device into the pxb-pcie. miaoyubo (2): arm: acpi: pci-expender-bus: Make arm to support PXB-PCIE pci-expender-bus:Add pcie-root-port to pxb-pcie under arm. hw/arm/virt-acpi-build.c | 234 ++++++++++++++++++++++++++-- hw/pci-bridge/pci_expander_bridge.c | 9 ++ hw/pci-host/gpex.c | 4 + include/hw/arm/virt.h | 1 + include/hw/pci/pcie_port.h | 1 + 5 files changed, 238 insertions(+), 11 deletions(-) -- 2.19.1
