2016-11-28MdePkg IndustryStandard: Add DDR3, DDR4 and LPDDR definition per SPD specLiming Gao
https://bugzilla.tianocore.org/show_bug.cgi?id=201 In V3, Use Odt to replace ODT, Cke to replace CKE, Id to replace ID, and Cl to replace CL in structure field name. In V2, separate DDR3, DDR4 and LPDDR definition into the different files; use the different SPD prefix as structure definitions for each SPD type.

2016-11-21MdePkg BaseLib: API PathRemoveLastItem not handle root paths properlyHao Wu
https://bugzilla.tianocore.org/show_bug.cgi?id=239 When the input path for API PathRemoveLastItem() is a root path like 'fs0:\', the API will return TRUE (indicating a directory or file was removed from the path) and modifies the path to 'fs0:'. In fact, there's no directory or file removed in the above case. This commit adds additional check to resolve this issue and modifies the API's description to make it more straightforward.

https://bugzilla.tianocore.org/show_bug.cgi?id=180 The PCI_SEGMENT_LIB_ADDRESS() macro puts the Segment number into bits 32..47 of the logical address that is returned. The portable method to put Segment in this bit range is to use LShitU64(). For 64-bit CPUs, this is optimized well by the compiler. For 32-bit CPUs, a call to LSHiftU64() is included in the generated binaries. However, if the Segment parameter is 0, then no shift is required. Add a check for Segment set to 0 and provide an optimized macro implementation that does not call LShiftU64().

2016-10-25MdePkg/DebugLib.h: add ASSERT_RETURN_ERROR()Laszlo Ersek
ASSERT_EFI_ERROR() cannot be used in BASE type modules because - the replacement text calls EFI_ERROR(), - EFI_ERROR() is defined in "MdePkg/Include/Uefi/UefiBaseType.h", - the inclusion of "UefiBaseType.h" is not required for BASE type modules. While ASSERT (!RETURN_ERROR (StatusParameter)) would be a functional statement in BASE type modules, it would be less convenient and less informative: ASSERT_EFI_ERROR() prints the actual StatusParameter. Hence add ASSERT_RETURN_ERROR(), paralleling ASSERT_EFI_ERROR(). Copy the original macro definition and update it as follows: - replace EFI with RETURN, - wrap overlong lines in the comment block and in the code, - EFI_D_ERROR is deprecated, so employ DEBUG_ERROR instead.

As reported by Vishal, CompareGuid() is a hotspot, and switching from BaseMemoryLibStm in ArmPkg/ to BaseMemoryLibOptDxe causes a noticeable performance regression due to the fact that BaseMemoryLibOptDxe uses unaligned accessors explicitly to implement CompareGuid() and the related functions. Since BaseMemoryLibOptDxe on ARM and AARCH64 can only be used in contexts where unaligned accesses are allowed, reimplement these functions for ARM and AARCH64 specifically, using wide accessors that can tolerate any misalignment.
