MdePkg/Library/BaseLib: Use PcdControlFlowEnforcementPropertyMask as fixed

2025-12-24T05:43:01+00:00

Always access PcdControlFlowEnforcementPropertyMask using FixedPcdGet() in NASM source files and update INFs to correctly declare that PcdControlFlowEnforcementPropertyMask is always accessed as a Fixed PCD. PcdControlFlowEnforcementPropertyMask is declared in MdePkg.dec in the [PcdsFixedAtBuild] section, so this PCD does not support any other PCD access types. This change resolves ld warnings from GCC and CLANGDWARF builds for relocations in read-only text sections because use of PcdGet() in NASM source files reads the value into eax from the memory location of a const global variable that requires a relocation fixup. By changing PcdGet() to FixedPcdGet(), eax is loaded with an immediate value known at build time and no relocation fixups for PcdControlFlowEnforcementPropertyMask are required.

MdePkg/BaseLib AARCH64: Drop special Unaligned.c version

2025-12-09T08:41:08+00:00

Now that the generic code takes alignment constraints into account, there is no longer a need for a special AArch64 version that performs byte by byte access in C. Signed-off-by: Ard Biesheuvel

MdePkg: Add code to detect running as an SEV guest

2025-11-04T06:51:50+00:00

Similar to Intel's Tdx, we need a mechanism to detect running as an AMD SEV guest that will work in all phases everywhere. This will be immediately used to prevent usage of MTRRs with SEV guests. Signed-off-by: Richard Relph

MdePkg: Remove ARM32 Support from BaseLib

2025-09-25T22:04:10+00:00

edk2 is dropping support for the ARM32 architecture. This commit removes ARM32 code from BaseLib. Signed-off-by: Oliver Smith-Denny

MdePkg/Library/BaseLib: Remove __chkstk() from BaseLib

2025-09-19T07:14:26+00:00

Remove workaround for GCC compilers that is no longer required. Keeping this implementation of __chkstk() generates duplicate symbol build failures with Windows/CLANGPDB builds host-based unit test builds. Signed-off-by: Michael D Kinney

MdePkg: BaseLib: Add UUID-GUID conversion function

2025-06-05T05:01:57+00:00

With interactions between Standalone MM partitions and normal UEFI environment, there is constant need to convert UUID to GUID and back. This change added 2 new interfaces to BaseLib that support such usage. Signed-off-by: Kun Qin

MdePkg/BaseLib: Add NULL version Tdx functions for other architectures

2024-09-09T02:57:02+00:00

Currently, the NULL version Tdx functions are only built for Ia32. In BaseLib, the others architectures also need such NULL version Tdx functions. Cc: Liming Gao Cc: Michael D Kinney Cc: Zhiguang Liu Cc: Gerd Hoffmann Cc: Jiewen Yao Cc: Min Xu Signed-off-by: Ceping Sun

MdePkg/BaseLib: AARCH64: Add ArmReadIdAA64Isar0Reg()

2024-08-01T13:41:01+00:00

To enable AARCH64 native instruction support for Openssl, some interfaces must be implemented. OPENSSL_cpuid_setup() allows to probe the supported features of the platform. Add ArmReadIdAA64Isar0Reg() to read the AA64Isar0, containing Arm64 instruction capabilities. A similar ArmReadIdAA64Isar0() function is available in the ArmPkg, but the CryptoPkg where OPENSSL_cpuid_setup will reside cannot rely on the ArmPkg. Signed-off-by: Pierre Gondois

MdePkg/BaseLib: AARCH64: Add ArmReadCntPctReg()

2024-08-01T13:41:01+00:00

To enable AARCH64 native instruction support for Openssl, some interfaces must be implemented. OPENSSL_rdtsc() requests an access to a counter to get some non-trusted entropy. Add ArmReadCntPctReg() to read system count. A similar ArmReadCntPct() function is available in the ArmPkg, but the CryptoPkg where OPENSSL_rdtsc will reside cannot rely on the ArmPkg.
