2025-09-09MdePkg: Add the COHERENCY_SFW_NO CPUID bit fieldTom Lendacky1-2/+7
Update the CPUID 0x8000001F EBX definition to add the COHERENCY_SFW_NO bit field. The COHERENCY_SFW_NO bit is used to indicate that the SEV-SNP cache coherency mitigation is not needed. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com>

2025-09-08Global: fix ArmFfaLibRun() caller couldn't get ret-argsLevi Yun1-2/+4
When ArmFfaLibDirectMsgReq(2) is preempted, caller of these functions should resume it works via ArmFfaLibRun() and the secure partition will be return with FFA_DIRECT_MSG_RESP(2) with return arguments. However, since ArmFfaLibRun() gets its return in its stack variable, So caller of ArmFfaLibRun() doesn't get the return arguments from secure partition. To resolve this, add output parameter to ArmFfaLibRun() to receive return arguments.

2025-09-05MdePkg/Include: Deprecate EFI_NVDIMM_LABEL_FLAGS_UPDATINGGowtham M1-5/+0
The EFI_NVDIMM_LABEL_FLAGS_UPDATING flag is used in UEFI to indicate that an update was in progress across multiple Label Storage Areas (LSAs) on NVDIMM devices. Its purpose was to help ensure atomicity in the event of interruptions like power loss or system crashes. It is deprecated in UEFI 2.10 and 2.11, as label index blocks and checksums now provide better atomicity and consistency without requiring this flag.

2025-09-05MdePkg/Include: Deprecate EFI_NVDIMM_LABEL_FLAGS_RESERVEDGowtham M1-6/+0
EFI_NVDIMM_LABEL_FLAGS_RESERVED is a reserved bit in the NVDIMM label flags field, intended for future use. It was removed in UEFI 2.10A and 2.11 as it had no defined function and was unused in implementations. Cc: Sachin Ganesh <sachinganesh@ami.com> Signed-off-by: Gowtham M <gowthamm@ami.com>

2025-09-05MdePkg: Enable CompilerIntrinsicsLib for LoongArchChao Li2-0/+12
When arrays are lager enough, LoongArch compilers(such as GCC or Clang) will replace some libc functions to improve performace, which may cause building failures. Enabling this library can link edk2's own libc functions and fix this problem.

2025-09-02MdePkg/Library/BaseRngLib/Riscv: use CPU RNG instructions onlyAdriano Cordova1-92/+3
Generate random number using risc-v CPU RNG instructions only, as for the other architectures. This is safer than using Mersenne Twister from a seed, which is the current implementation, as the latter is known to be cryptographically unsafe (e.g. see https://www.schutzwerk.com/en/blog/attacking-a-rng/) Signed-off-by: Adriano Cordova <adriano.cordova@canonical.com>

2025-08-26MdePkg/BaseFdtLib: Remove unused macros and string APIsThamballi Sreelalitha1-20/+11
Removed legacy macros and string helper APIs that are no longer used in the BaseFdtLib implementation. Specifically: - Dropped strcmp macro that incorrectly expected 3 arguments but ignored the third parameter. - Cleaned up other unused macros and redundant string APIs. These changes align with the current upstream libfdt module and reduce dead code. Signed-off-by: Thamballi Sreelalitha <sreelali@qti.qualcomm.com>
2025-08-12MdePkg, EmbeddedPkg: Move Fdt Table Guid to MdePkgPrachotan Bathi2-0/+21
Move Fdt Table Guid from EmbeddedPkg to MdePkg to avoid unnecessary dependencies on EmbeddedPkg for packages like ShellPkg. This change may affect modules dependent on EmbeddedPkg but not on MdePkg, which is unlikely. Also, per 8c721d6, MdePkg has a more refined implementation of Fdt as compared to the EmbeddedPkg which was the initial implementation. Not moving gFdtVariableGuid since it'll be moved to platform code. Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Prachotan Bathi <prachotan.bathi@arm.com>

2025-08-06MdePkg/Library: Remove MM_STANDALONE LibraryClass in UefiDevicePathLib.infGowtham M1-1/+1
UefiDevicePathLib.inf consumes Boot Services in MdePkg/Library/UefiDevicePathLib/DevicePathUtilitiesDxeSmm.c - DevicePathFromHandle(). And so cannot be used by MM_STANDALONE drivers. Instead, MM_STANDALONE drivers can use UefiDevicePathLibBase.inf as the DevicePathLib of choice. Cc: Sachin Ganesh <sachinganesh@ami.com> Signed-off-by: Gowtham M <gowthamm@ami.com>
2025-08-06MdePkg/Library: Remove UefiDevicePathLibStandaloneMm.infGowtham M2-79/+0
The file UefiDevicePathLibStandaloneMm.inf was reintroduced in [#3187] to give downstream platforms time to transition to UefiDevicePathLibBase.inf As nearly three years have passed since that change, and downstream consumers have had sufficient time to migrate, this library can now be safely removed.

2025-07-14MdePkg: Add DEBUG_SECURITY Bit in PcdDebugPrintErrorLevelOliver Smith-Denny2-1/+4
Tcg2Dxe and its libraries are currently the noisiest modules in edk2. For a sample platform printing at INFO level, Tcg2Dxe printed 4,000 lines out of 5,700 total lines printed. This commit defines a DEBUG_SECURITY bit to control the debug output of Tcg2Dxe and other security related components. Most of the output is not useful except for deep debugging of TPM transactions, so it is appropriate to only print when the DEBUG_SECURITY bit is present.

FFA is a framework that supports various protocols built on top. i.e. memory protocol, which is nothing that can be done through existing interfaces. Instead of requiring protocol authors to check conduit PCD in every implementation, exposing the ArmCallFfa is a unified way to allow other protocols to leverage FFA interfaces.
