EmbeddedPkg: Clear keyboard queue buffer after reading

2025-10-09T08:02:51+00:00

There is a possibility to retrieve user input keystroke data stored in the queue buffer via the EFI_SIMPLE_TEXT_INPUT_PROTOCOL pointer. To prevent exposure of the password string, clear the queue buffer by filling it with zeros after reading. Signed-off-by: Nick Wang

EmbeddedPkg: Drop ARM32 Support

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

edk2 is dropping support for the ARM32 architecture. This commit removes ARM32 code from EmbeddedPkg. This also drops irrelevant VALID_ARCHITECTURES comments from infs that are not arch specific. Signed-off-by: Oliver Smith-Denny

EmbeddedPkg: Fix a data error in comment

2025-06-04T06:13:22+00:00

KEYBOARD_TIMER_INTERVAL is used as TriggerTime parameter of gBS->SetTimer() function. TriggerTime parameter represents the number of 100ns units, so number 500000 indicates 0.05s. Signed-off-by: Gao Qihang

ArmVirtPkg,DynamicTablesPkg,EmbeddedPkg,OvmfPkg: use MdePkg BaseFdtLib

EmbeddedPkg: Remove misleading error message in FindNextMemoryNodeReg

2025-01-09T11:35:00+00:00

FindNextMemoryNodeReg prints "ignoring disabled memory node" for all top-level disabled nodes in the tree, not just the ones with the "device_type" property set to "memory". Rework the loop to only print the message for the relevant nodes. Signed-off-by: Oleksandr Tymoshenko

Add missing includes of BaseMemoryLib.h and declaration of BaseLib/BaseMemoryLib dependencies hidden by use of EmbeddedPkg FdtLib, which is being deleted. Signed-off-by: Leif Lindholm

EmbeddedPkg: Add option to disable EFI Memory Attribute Protocol

2024-07-16T09:54:07+00:00

Introduce a driver that allows users to disable the EFI Memory Attribute protocol through an HII setup option, in order to work around a broken version of rhboot's shim used in some distros (e.g. CentOS Stream 9) which incorrectly invokes the protocol and results in a Synchronous Exception. Default is enabled, which can also be overridden at build time by changing `gEmbeddedTokenSpaceGuid.PcdMemoryAttributeEnabledDefault`. It is only applicable to ARM64 and there isn't any other technical reason for disabling this security feature.

EmbeddedPkg/NonCoherentIoMmuDxe: Make SetAttributes always succeed

2024-03-12T17:39:01+00:00

NonCoherentIoMmuSetAttribute() does nothing except return EFI_UNSUPPORTED. This was fine when it was introduced, but now, the PCI bus driver will fail a PCI I/O Map() operation if the call to SetAttributes() fails. So return EFI_SUCCESS instead.

EmbeddedPkg: Update code to be more C11 compliant by using func

2023-04-10T14:19:57+00:00

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among others support, while __func__ was standardized in C99. Since it's more standard, replace __FUNCTION__ with __func__ throughout EmbeddedPkg. Signed-off-by: Rebecca Cran Reviewed-by: Michael D Kinney Reviewed-by: Ard Biesheuvel Reviewed-by: Abner Chang
