EDK_r5418-5419: Non-Compatible: qhuang8
|
|
Class_Library: Update EfiDriverLib in ECP to make it compatible with EDK1.01(EDK1117),
|
|
but the change itself is incompatible.
|
|
With this change, EFI1.10 drivers can be directly dropped
|
|
in and built in UEFI build mode. EfiLibInstallAllDriverProtocols2() and
|
|
INSTALL_ALL_DRIVER_PROTOCOLS_OR_PROTOCOLS2() are added to support UEFI driver
|
|
model protocols. Please replace all the occurrences of EfiLibInstallAllDriverProtocols
|
|
and INSTALL_ALL_DRIVER_PROTOCOLS with INSTALL_ALL_DRIVER_PROTOCOLS_OR_PROTOCOLS2
|
|
in Edk 1.04 based source tree.
|
|
|
|
Code Change:
|
|
1) Edk\Foundation\Include\EfiCompNameSupport.h:
|
|
Add macro INSTALL_ALL_DRIVER_PROTOCOLS_OR_PROTOCOLS2().
|
|
2) Edk\Foundation\Library\Dxe\EfiDriverLib\EfiDriverModelLib.c
|
|
Edk\Foundation\Library\Dxe\Include\EfiDriverLib.h
|
|
Update EfiLibInstallAllDriverProtocols() and add EfiLibInstallAllDriverProtocols2()
|
|
|
|
Possible impact:
|
|
1) If your "EDK style" code base is based on ECP r5417 or below, please replace all the
|
|
occurrences of EfiLibInstallAllDriverProtocols and INSTALL_ALL_DRIVER_PROTOCOLS with
|
|
INSTALL_ALL_DRIVER_PROTOCOLS_OR_PROTOCOLS2
|
|
|
|
|
|
==========================================================================================
|
|
EDK_r4955: Non-Compatible: qhuang8
|
|
|
|
Class_HFile: Update the Device Type Value of MEDIA_FV_DP & MEDIA_FV_FILEPATH_DP.
|
|
The definitions in MdePkg have already been updated in r4632. This will remove the
|
|
potential compatibility issues when native EDK II modules & EDK modules built with
|
|
ECP and run with EDK II core.
|
|
|
|
Code Change:
|
|
1) Reverse the value of MEDIA_FV_DP & MEDIA_FV_FILEPATH_DP to fix a UEFI errata.
|
|
|
|
|
|
Possible impact:
|
|
1) EDK I modules built with this update might not work with old EDK environment.
|
|
|
|
|
|
==========================================================================================
|
|
EDK_r4960: Non-Compatible: qhuang8
|
|
|
|
Class_HFile: Remove the default value 0xE0000000 of EDKII_GLUE_PciExpressBaseAddress.
|
|
It now requires platform DSC file to specify it explicitly to avoid runtime issue
|
|
if they ever uses PciExpressLib in EDK GlueLib.
|
|
Unlike other default value in GlueLib, this value might not function for all real
|
|
platforms.
|
|
|
|
Code Change:
|
|
1) Replace 0xE0000000 to be PCD_EDKII_GLUE_PciExpressBaseAddress.
|
|
|
|
Possible impact:
|
|
1) If a platform ever uses PciExpressLib in Glue Lib. It needs to explictly specify
|
|
the value of PCD_EDKII_GLUE_PciExpressBaseAddress for their platform to function.
|
|
e.g. in EDK II DSC file to build EDK modules:
|
|
[BuildOptions]
|
|
*_*_*_CC_FLAGS = /D PCD_EDKII_GLUE_PciExpressBaseAddress=0xC0000000
|
|
|
|
|
|
EDK_r7286: Compatible: qhuang8
|
|
|
|
Class_HFile: Add several new UEFI definition to build with newest EFI shell source.
|
|
|
|
Code Change:
|
|
1) Add new UEFI Load File 2 protocol defininition.
|
|
2) Add MEDIA_RELATIVE_OFFSET_RANGE_DEVICE_PATH device path type.
|
|
|
|
Possible impact:
|
|
None. |
