That is a simple console implementation that can works on both PVH guest and HVM guests, even if it rarely going to be use on HVM. Have PlatformBootManagerLib look for the new console, when running as a Xen guest. Since we use VENDOR_UART_DEVICE_PATH, fix its description and coding style. Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=1689 Signed-off-by: Anthony PERARD Reviewed-by: Laszlo Ersek --- Notes: v4: - instead of creating a new XEN_CONSOLE_DEVICE_PATH, use the existing VENDOR_UART_DEVICE_PATH. And explain why VENDOR_UART_DEVICE_PATH changed in the commit message. v3: - removed PciSioSerialDxe and IsaSerialDxe from OvmfXen, since they would not be used, maybe, to check. - some coding style fix - not changed: PciSioSerialDxe: even if we add SerialDxe, we still needs PciSioSerialDxe to have OVMF use the emulated serial port on HVM. v2: - Use MdeModulePkg/Universal/SerialDxe instead of something new. - Have PlatformInitializeConsole() look for it by using the known-in-advance device path for the xen console in the PLATFORM_CONSOLE_CONNECT_ENTRY.
