| H A D | pci-bridge-emul.h | 05241c13 Tue Jan 04 09:35:22 CST 2022 Pali Rohár <pali@kernel.org> PCI: pci-bridge-emul: Add support for new flag PCI_BRIDGE_EMUL_NO_IO_FORWARD
Like PCI_BRIDGE_EMUL_NO_PREFMEM_FORWARD, this new flag specifies that
emulated PCI bridge does not support forwarding of IO requests in given
range between primary and secondary buses. This flag should be used as
argument for pci_bridge_emul_init() for hardware setup without IO support.
Setting this flag cause that IO base and limit registers are read-only.
