From 9343d0a1cd09544686b14dba5b428d7bc811f6b9 Mon Sep 17 00:00:00 2001 From: Dandan Bi Date: Fri, 5 Oct 2018 17:30:31 +0800 Subject: [PATCH] MdePkg: Use VENDOR_DEVICE_PATH structure for Debug Port device path REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1229 When converting DebugPort device path from text, current code use VENDOR_DEFINED_MESSAGING_DEVICE_PATH structure for Debug port device node. typedef struct { EFI_DEVICE_PATH_PROTOCOL Header; EFI_GUID Guid; UINT8 VendorDefinedData[1]; } VENDOR_DEFINED_MESSAGING_DEVICE_PATH; And Debugport Device Path is a vendor-defined messaging device path with no data, only a GUID. So it's better to use VENDOR_DEVICE_PATH to create the Debug port device node. typedef struct { EFI_DEVICE_PATH_PROTOCOL Header; EFI_GUID Guid; } VENDOR_DEVICE_PATH; Cc: Ruiyu Ni Cc: Michael D Kinney Cc: Liming Gao Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Dandan Bi Reviewed-by: Ruiyu Ni --- MdePkg/Library/UefiDevicePathLib/DevicePathFromText.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/MdePkg/Library/UefiDevicePathLib/DevicePathFromText.c b/MdePkg/Library/UefiDevicePathLib/DevicePathFromText.c index c5f3764fc0..49da8268eb 100644 --- a/MdePkg/Library/UefiDevicePathLib/DevicePathFromText.c +++ b/MdePkg/Library/UefiDevicePathLib/DevicePathFromText.c @@ -1758,12 +1758,12 @@ DevPathFromTextDebugPort ( IN CHAR16 *TextDeviceNode ) { - VENDOR_DEFINED_MESSAGING_DEVICE_PATH *Vend; + VENDOR_DEVICE_PATH *Vend; - Vend = (VENDOR_DEFINED_MESSAGING_DEVICE_PATH *) CreateDeviceNode ( + Vend = (VENDOR_DEVICE_PATH *) CreateDeviceNode ( MESSAGING_DEVICE_PATH, MSG_VENDOR_DP, - (UINT16) sizeof (VENDOR_DEFINED_MESSAGING_DEVICE_PATH) + (UINT16) sizeof (VENDOR_DEVICE_PATH) ); CopyGuid (&Vend->Guid, &gEfiDebugPortProtocolGuid); -- 2.39.2
