| l4_gpa_t | base, | |||
| l4_gpa_t | size = 1 | |||
| ) | const [pure virtual] |
Searchs an I/O region and returns it in a search_result struct.
base & size are I/O space addresses or guest physical addresses depending on the type to search for.
Implemented in pci_device_base< SpaceT >, pci_device_base< l4io_device_config_space >, pci_device_base< piix_ide_config_space >, and pci_device_base< dummy_device_config_space >.
| virtual l4_umword_t pci_device::read_config_space | ( | pci_config_header16::offset_t | offset, | |
| access_size | access_size | |||
| ) | [pure virtual] |
Emulates a device's PCI configuration space read access and returns the value that should have been read.
This function is intended to be overridden.
Implemented in i440fx_host_bridge, pci_device_base< SpaceT >, l4io_device, pci_device_base< l4io_device_config_space >, pci_device_base< piix_ide_config_space >, and pci_device_base< dummy_device_config_space >.

| ) | [pure virtual] |
Emulates a device's PCI configuration space write access.
This function is intended to be overridden.
Implemented in i440fx_host_bridge, pci_device_base< SpaceT >, dummy_device, l4io_device, piix_ide, pci_device_base< l4io_device_config_space >, pci_device_base< piix_ide_config_space >, and pci_device_base< dummy_device_config_space >.
