What function would you want to implement?
Display (including HDMI display interface) are initialized by Intel GOP (Graphic OutPut Protocol) driver. It locates at Vlv2MiscBinariesPkg\GOP\7.2.1011\RELEASE_VS2008x86\X64\IntelGopDriver.efi.
EFI_GRAPHICS_OUTPUT_PROTOCOL protocol, which is produced by this driver, provides functions to manipulate display. Please search in MinnowBoard Max source code to get samples on how to uses this protocol.
typedef struct _EFI_GRAPHICS_OUTPUT_PROTOCOL EFI_GRAPHICS_OUTPUT_PROTOCOL;
struct _EFI_GRAPHICS_OUTPUT_PROTOCOL {
EFI_GRAPHICS_OUTPUT_PROTOCOL_QUERY_MODE QueryMode;
EFI_GRAPHICS_OUTPUT_PROTOCOL_SET_MODE SetMode;
EFI_GRAPHICS_OUTPUT_PROTOCOL_BLT Blt;
EFI_GRAPHICS_OUTPUT_PROTOCOL_MODE *Mode;
};
extern EFI_GUID gEfiGraphicsOutputProtocolGuid;
