the direct variable update in PasswordSmmInit fails with an EFI_NOT_AVAILABLE_YET error. This occurs because the initial NV variable write relies on the EFI_VARIABLE_WRITE_ARCH_PROTOCOL, which has not yet been installed during the early DXE/SMM init phase.

VirtualKeyboardFeaturePkg: convert SimpleIcon and FullIcon BMPs to paletted

2026-04-22T18:18:15+00:00

Follow-up to the 4-bit keyboard BMP conversion in PR #969 for the remaining two icon assets in VirtualKeyboardDxe. SimpleIcon.bmp uses only 2 unique colors (pure black/white); convert to 1-bit paletted BMP for a byte-level lossless reduction. FullIcon.bmp uses 198 unique colors; convert to 8-bit paletted BMP for a byte-level lossless reduction (198 < 256 palette entries, no quantization required). EDK2 BaseBmpSupportLib already supports 1-bit and 8-bit uncompressed BMP (TranslateBmpToGopBlt handles both BitsPerPixel values). Per-file size reduction (24-bit -> target): SimpleIcon.bmp: 2814 -> 182 (1-bit) FullIcon.bmp: 5454 -> 2878 (8-bit) Pixel dimensions and visual layout are unchanged. Signed-off-by: James Lu

VirtualKeyboardFeaturePkg: convert keyboard BMPs to 4-bit palette

2026-04-02T08:10:42+00:00

Convert the three VirtualKeyboardDxe keyboard bitmap assets from 24-bit BMP to 4-bit paletted BMP. Each bitmap uses fewer than 16 unique colors after median-cut quantization, so the 16-color palette is sufficient. Pixel dimensions and visual layout are unchanged. EDK2 BaseBmpSupportLib already supports 4-bit uncompressed BMP (TranslateBmpToGopBlt handles BitsPerPixel==4). Per-file size reduction (24-bit -> 4-bit): CapitalLetterKeyboard.bmp: 330454 -> 55318 DigitKeyboard.bmp: 330454 -> 55318 SimpleKeyboard.bmp: 30054 -> 5318 Signed-off-by: James Lu

Features/Intel: Improper Return Status

2025-10-27T22:35:10+00:00

SmmPasswordHandler returns EFI_SUCCESS even when the CommBufferSize is less than the expected header size. Change the return statement to return an appropriate error code EFI_INVALID_PARAMETER instead of EFI_SUCCESS. Signed-off-by: Reji, RencyX

Features/Intel: Failed to check return status

2025-10-18T01:24:02+00:00

KeyLibGenerateSalt function fails to check the return values of RandomSeed and RandomBytes function calls. Also SavePasswordToVariable fails to check return value from KeyLibGenerateSalt. Added error handling code to check the return values of RandomSeed, RandomBytes functions and KeyLibGenerateSalt in SavePasswordToVariable. Signed-off-by: Reji, RencyX

Pkg-Module: Features/VirtualKeyboardDxe PART 2

2024-11-28T07:03:21+00:00

The Keyboard.c driver did not include ScanCodes like F1,F2,F12,etc. and UnicodeChars like Backspace, Tab in VK_NOTIFY NotifyList which is why these keys were not getting registered and not getting pushed in the KeyBuffer stack which resulted in undefined behavior of continuous backspace and not recognizing the relevant key push after the buffer overflow condition.
