const PciBar * bar (size_t n)

Returns a pointer to a base address register for this device.

Returns nullptr if the register is not implemented.

Defined at line 172 of file ../../src/virtualization/bin/vmm/pci.h

const Attributes & attrs ()

Return static device attributes.

Defined at line 175 of file ../../src/virtualization/bin/vmm/pci.h

zx_status_t ReadConfig (uint64_t reg, IoValue * value)

Handle accesses to this device config space.

template <typename T>

zx_status_t AddCapability (const T & capability)

Install the given standard layout, trivially copyable type as a PCI capability.

Capabilities types must have a size aligned to 32-bits.

The "next" pointer in cap header (byte 2) will be overwritten by

the function, and need not contain any particular value.

Defined at line 423 of file ../../src/virtualization/bin/vmm/pci.cc

zx::result<size_t> AddBar (PciBar bar)

Install the given PciBar in the next available slot, returning the index

the PciBar was installed at.

Returns ZX_ERR_NO_RESOURCES if all BARs have already been used.
