UefiHidDxeV2: Add keystroke repeat functionality @joschock (#883)

Change Details

Description

Implement keyboard repeat for held keys, matching the behavior of the legacy C HidKeyboardDxe driver:

• 500ms initial delay before repeat begins
• 20ms repeat rate (~50 keys/sec) while key is held
• Modifier keys, toggle keys, and non-spacing (dead) keys are excluded
• Last newly pressed repeatable key wins in multi-key reports
• Timer cancelled on key release or keyboard reset

• [ ] Impacts security?
• [ ] Breaking change?
• [x] Includes tests?
• [ ] Includes documentation?

How This Was Tested

Included unit tests, tested on hardware at UEFI shell and confirmed expected repeat behavior.

Integration Instructions

None.

Fix missing UefiLib dependency in MfciPolicyParsingUnitTestApp @GiriMohanNaidu (#887)

Change Details

Description

Added the missing UefiLib library class dependency to MfciPolicyParsingUnitTestApp.inf. The module uses UefiLib APIs but did not declare the dependency in its [LibraryClasses] section, causing build failures when the library was not implicitly pulled in by the platform DSC. The module uses AsciiPrint() from UefiLib but did not declare the dependency in its LibraryClasses section.

• [X] Impacts functionality? No — build fix only; no logic changes.
• [ ] Impacts security?
• [ ] Breaking change?
• [ ] Includes tests? N/A — fixes the test app itself so it builds correctly.
• [ ] Includes documentation?

How This Was Tested

Built MfciPkg/UnitTests/MfciPolicyParsingUnitTest/MfciPolicyParsingUnitTestApp.inf and confirmed the build completes without missing library errors.

Integration Instructions

N/A — consumers of MfciPkg do not need any changes; this only affects the unit test app build.

Migrate mu\_plus from mu\_uefi\_boot\_services crate to patina crate @vineelko (#881)

Change Details

Description

• mu_uefi_boot_services is not maintained and its functionality is moved into patina.
• The mu_uefi_boot_services's crates.io point to non-existent repo.
• This cleanup is needed to move mu_plus's r-efi dependency to 6.0

Next, Once Patina is updated to r-efi 6.0 we can migrate mu_plus to patina vnext and r-efi to 6.0

AdvLoggerPkg/AdvancedLoggerLib: Print to HW if logger info is not available @makubacki (#876)

Change Details

Description

In the course of testing advanced logger changes with edk2 Standalone MM on OVMF, there was a change needed in MmPlatformHobProducerLibOvmf in OvmfPkg to account for gAdvancedLoggerHobGuid in the HOBs that are passed to the MM environment.

Prior to this change, the system appeared to hang entering that environment:

INFO - Loading PEIM at 0x00005B95000 EntryPoint=0x00005B95340 StandaloneMmIplPei.efi
INFO - StandaloneMM IPL loading MM Core at MMRAM address 7FF0000
INFO - MmCoreImageBase - 0x0000000007FF0000
INFO - MmCoreImageSize - 0x0000000000010000
INFO - StandaloneMM IPL calling Standalone MM Core at MMRAM address - 0x0000000007FF1000

After the change, the issue is clearly printed to serial output: ("MmCore AdvancedLoggerGetLoggerInfo: Advanced Logger Hob not found")

INFO - Loading PEIM at 0x00005B94000 EntryPoint=0x00005B94340 StandaloneMmIplPei.efi
INFO - StandaloneMM IPL loading MM Core at MMRAM address 7FF0000

INFO - MmHobStart - 0x7FEE810
INFO - MmInstallConfigurationTable For HobList
INFO - ASSERT [StandaloneMmCore] AdvancedLoggerLib.c(164): mLoggerInfo != ((void *) 0)

This change allows writes to proceed to hardware output if enabled even if the logger info is not available, to make information such as this available for debugging purposes.
