hw/pci: PCIe Data Object Exchange emulation
Emulation of PCIe Data Object Exchange (DOE)
PCIE Base Specification r6.0 6.3 Data Object Exchange
Supports multiple DOE PCIe Extended Capabilities for a single PCIe
device. For each capability, a static array of DOEProtocol should be passed
to pcie_doe_init(). The protocols in that array will be registered under
the DOE capability structure. For each protocol, vendor ID, type, and
corresponding callback function (handle_request()) should be implemented.
This callback function represents how the DOE request for corresponding
protocol will be handled.
pcie_doe_{read/write}_config() must be appended to corresponding PCI
device's config_read/write() handler to enable DOE access. In
pcie_doe_read_config(), false will be returned if pci_config_read()
offset is not within DOE capability range. In pcie_doe_write_config(),
the function will have no affect if the address is not within the related
DOE PCIE extended capability.
