Defined at line 678 of file fidling/gen/sdk/fidl/fuchsia.hardware.pci/fuchsia.hardware.pci/cpp/fidl/fuchsia.hardware.pci/cpp/wire_messaging.h
Methods to make a sync FIDL call directly on an unowned handle or a
const reference to a |::fidl::ClientEnd
<
::fuchsia_hardware_pci::Bus>|,
avoiding setting up a client.
Public Methods
::fidl::WireResult< ::fuchsia_hardware_pci::Bus::GetHostBridgeInfo> GetHostBridgeInfo ()Retrieve information about the segment group and buses covered by a Bus.
Allocates 88 bytes of message buffer on the stack. No heap allocation necessary.
::fidl::WireResult< ::fuchsia_hardware_pci::Bus::GetDevices> GetDevices ()Retrieve all Devices on the Bus.
Allocates 16 bytes of request buffer on the stack. Response is heap-allocated.
::fidl::WireResult< ::fuchsia_hardware_pci::Bus::ReadBar> ReadBar (const ::fuchsia_hardware_pci::wire::Address & device, uint8_t bar_id, uint64_t offset, uint64_t size)Read from a Device's base address register (BAR). The BAR must be an MMIO type.
Parameters
|device|: The address of the device to read from.
|bar_id|: The ID of the BAR to read.
|offset|: The offset, in bytes, to start the read (default: 0 bytes).
|size|: The size of the read (default: 128 bytes). The max size for a
read is |READBAR_MAX_SIZE|.
Errors:
|ZX_ERR_NOT_FOUND|: |device| was not found, or |bar_id| did not exist in |device|.
|ZX_ERR_INVALID_ARGS|: |bar_id| is invalid, or offset / size combined
are invalid for the given BAR's size.
|ZX_ERR_NOT_SUPPORTED|: The BAR specified by |bar_id| is not an MMIO BAR.
Allocates 40 bytes of request buffer on the stack. Response is heap-allocated.
