MdePkg/BasePrintLib: Limit UCS-2 to ASCII conversion to Latin-1

2026-09-21T08:46:42+00:00

Only ASCII and Latin-1 characters can be cast between CHAR8 and CHAR16 transparently, other characters in the UCS-2 set cannot be represented at all. So when handling the %s conversion while generating a narrow string, replace characters outside of the Latin-1 range with a '?' character instead of producing garbage output, which may truncate the output string inadvertently if the UCS-2 low byte happens to equal \0. When the input and output character widths are the same, the encoding does not matter and the input can simply be copied to the output. Signed-off-by: Ard Biesheuvel

MdePkg/BaseFdtLib: Use BaseLib strrchr/strtoul, drop LibFdtWrapper.c

2026-09-15T10:49:49+00:00

Point the strrchr and strtoul macros in LibFdtSupport.h at the new AsciiStrRChr() and AsciiStrToUintn() BaseLib APIs instead of the private fdt_strrchr()/fdt_strtoul() implementations. This removes duplicated logic and picks up the overflow-detection already present in the underlying AsciiStrHexToUintnS()/AsciiStrDecimalToUintnS() conversion routines. LibFdtWrapper.c is now empty of purpose and is removed, along with its entry in BaseFdtLib.inf. Signed-off-by: Vishal Oliyil Kunnil

MdePkg/BaseLib: Add AsciiStrToUintn and AsciiStrToUint64

2026-09-15T10:49:49+00:00

Add AsciiStrToUintn() and AsciiStrToUint64() to BaseLib. These are thin wrappers that dispatch to the existing AsciiStrHexToUintnS()/ AsciiStrDecimalToUintnS() (and UINT64 equivalents) based on Base, which must be 0 (auto-detect via a "0x"/"0X" prefix), 10, or 16. No new radix-parsing logic is introduced; the existing conversion routines already cover the bases actually used in practice. Signed-off-by: Vishal Oliyil Kunnil

MdePkg/BaseLib: Add AsciiIsSpace

2026-09-15T10:49:49+00:00

Add AsciiIsSpace() to BaseLib, which checks whether an ASCII character is a space character as defined by the ISO C isspace() function. This will be used to implement AsciiStrToUintn() and AsciiStrToUint64(). Signed-off-by: Vishal Oliyil Kunnil

MdePkg/BaseLib: Add AsciiStrRChr

2026-09-15T10:49:49+00:00

Add AsciiStrRChr() to BaseLib, which returns the last occurrence of a character in a Null-terminated ASCII string. This mirrors the existing AsciiStrStr() API style and provides a reusable implementation for consumers that currently hand-roll this logic. Signed-off-by: Vishal Oliyil Kunnil

MdePkg/CompilerIntrinsicsLib: Fix IA32 with VS202x

2026-09-11T17:37:25+00:00

CompilerIntrinsicsLib is causing a #UD when used in IA32 mode. This was tracked back to memcpy using size_t, which locally defined in the file as __int64. When compiling for IA32 target, this results in the memcpy interpreting 64 bits from the calling convention instead of the 32 bits that were passed. Update the local size_t defines to use UINTN. This matches the functionality from CryptoPkg's Intrinsic functions. Add CompilerIntrinsics to IA32/X64 component so it is complied as part of CI. Add size_t as ECC check exclusion to MdePkg.ci.yaml.

MdePkg: ArmFfaMemMgmtLib: Fix ECC check failures

2026-09-06T10:12:38+00:00

This change fixes some ECC check failures around the usage of doxygen keywords. Signed-off-by: Kun Qin

MdePkg: UnitTestHostBaseLib: Support reading CNTPCT_EL0, ID_AA64ISAR0_EL1

2026-09-06T10:12:38+00:00

This change adds the support of reading CNTPCT_EL0 and ID_AA64ISAR0_EL1 through current BaseLib definition. This paves way to allow the linkage of these functions needed on other host based unit tests. Signed-off-by: Kun Qin

MdePkg: UnitTestHostBaseLib: Clean up source entries

2026-07-31T15:16:47+00:00

The existing UnitTestHostBaseLib has some source entries that are either redundant or for unsupported architectures. This change consolidated the redundant entries and removed the entries for unsupported architectures. Signed-off-by: Kun Qin
