bool DriverShouldProxyConfig ()

Contemporary methods:

Returns true if the bus driver should proxy all device config access to pciroot. This is

necessary in cases of IO config on x86, or for controllers that require configuration to

map in device config headers.

zx_status_t GetAddressSpace (uint64_t in_base, uint64_t size, pci_address_space_t type, bool low, uint64_t * out_base, zx::resource * out_resource, zx::eventpair * out_token)

Request address space reservations from platform bus to use for mapping bars / bridges

|in_base| is an optional requested start address which should otherwise be 0. |size| is the

size of the request in bytes. |low| dictates whether the allocation should be an address

below 4 GB or not.

On success, the base address is provided in |out_base| and the size is |size|.

An error will be returned if |size| cannot be fulfilled, |low| is set with |in_base|+|size|

being >=4GB, or if a requested |in_base| cannot be provided.

zx_status_t GetMsiHandle (zx::msi allocation, uint32_t options, uint16_t msi_id, zx::vmo cfg_vmo, uint64_t cfg_offset, zx::interrupt * out_interrupt)

Get a handle corresponding to an InterruptDispatcher for the provided |msi_id| in |allocation|.

Errors:

|ZX_ERR_INVALID_ARGS|: |options| is not 0, |msi_id| is out of bounds,

or |cfg_vmo| contains an invalid VMO handle.

|ZX_ERR_ALREADY_BOUND|: A handle for |msi_id| has already been returned and is still

outstanding.
