Public Methods

PciReg32 kBAR (uint bar)

0x10 is the address of the first BAR in config space

BAR rather than BaseAddress for space / sanity considerations

fbl::RefPtr<PciConfig> Create (uintptr_t base, PciAddrSpace addr_type)

Create a Pci Configuration object of the appropriate type.

Parameters

base The base address for the PCI configuration space.
addr_type An enum value of PciAddrSpace to identify the time of addressspace the configuration object will use.

Returns

a pointer to a new PciConfig instance on success, nullptr on failure.
