EmulatorPkg: Resolve GptLib library class

2026-07-20T21:50:57+00:00

GptLib is a new library class consumed both by PartitionDxe (built by essentially every platform) and by DxeTpm2MeasureBootLib. Any platform DSC that builds either module must resolve the GptLib library class, otherwise the build fails with "Instance of library class [GptLib] is not found". Resolve GptLib in EmulatorPkg/EmulatorPkg.dsc, which builds PartitionDxe. Out-of-tree platforms consuming either module need the same one-line resolution. Signed-off-by: Richard Lyu

EmulatorPkg: Remove VS2017 Visual Studio solution

2026-06-30T21:42:50+00:00

VS2017 support is being removed from edk2. This Visual Studio solution built the EmulatorPkg host with the VS2017 toolchain (`-t VS2017`), which will no longer exist in tools_def.template. The EmulatorPkg documentation and CI build with VS2022, so the VS2017 solution is removed. Signed-off-by: Michael Kubacki

EmulatorPkg: Replace manual alignment checks with helper macros

2026-06-09T07:20:10+00:00

Replace manual alignment checks with IS_ALIGNED() and ADDRESS_IS_ALIGNED(). Convert the following bitmask and modulo forms: - ((E & ((PowOf2Expr) - ONE)) == ZERO) - ((E & ((PowOf2Expr) - ONE)) != ZERO) - ((E % (PowOf2Expr)) == ZERO) - ((E % (PowOf2Expr)) != ZERO) to the corresponding helper macro forms: + IS_ALIGNED (E, PowOf2Expr) + !IS_ALIGNED (E, PowOf2Expr) PowOf2Expr is limited to known power-of-two expressions, including SIZE_* and BASE_* macros, EFI_PAGE_SIZE, CPU_STACK_ALIGNMENT, RUNTIME_PAGE_ALLOCATION_GRANULARITY, sizeof() of UEFI integer types (e.g. BOOLEAN, CHAR16, UINT32, UINTN) and pointer types, and 1 << E1 expressions. Address checks that cast the checked value to UINTN are written with ADDRESS_IS_ALIGNED(). The change was generated with the Coccinelle semantic patch below. ```smpl @power_of_2_expr@ expression PowOf2Expr; expression E1; typedef BOOLEAN, CHAR8, CHAR16, INT8, UINT8, INT16, UINT16, INT32, UINT32, INT64, UINT64, INTN, UINTN; type ScalarType = { BOOLEAN, CHAR8, CHAR16, INT8, UINT8, INT16, UINT16, INT32, UINT32, INT64, UINT64, INTN, UINTN }; type AnyType; type PointerType = AnyType *; idexpression ScalarType ScalarValue; idexpression PointerType PointerValue; constant SizeBase =~ "^(SIZE|BASE)_(1|2|4|8|16|32|64|128|256|512)[KMGTPE]B$"; constant NamedPowerOf2 =~ "^(EFI_PAGE_SIZE|CPU_STACK_ALIGNMENT|RUNTIME_PAGE_ALLOCATION_GRANULARITY)$"; constant ONE = {1, 1U, 1u}; @@ ( ( SizeBase | NamedPowerOf2 | ONE << E1 | sizeof (ScalarType) | sizeof (PointerType) | sizeof (ScalarValue) | sizeof (PointerValue) ) & PowOf2Expr ) @aligned depends on power_of_2_expr disable is_zero,isnt_zero@ expression E; expression power_of_2_expr.PowOf2Expr; constant ONE = {1, 1U, 1u}; constant ZERO = {0, 0U, 0u}; @@ ( ((E & (E - ONE)) == ZERO) | - ((E & ((PowOf2Expr) - ONE)) == ZERO) + IS_ALIGNED (E, PowOf2Expr) | ((E & (E - ONE)) != ZERO) | - ((E & ((PowOf2Expr) - ONE)) != ZERO) + !IS_ALIGNED (E, PowOf2Expr) | - ((E % (PowOf2Expr)) == ZERO) + IS_ALIGNED (E, PowOf2Expr) | - ((E % (PowOf2Expr)) != ZERO) + !IS_ALIGNED (E, PowOf2Expr) ) @address_is_aligned@ typedef UINTN; expression *Address; expression Alignment; @@ - IS_ALIGNED ((UINTN) Address, Alignment) + ADDRESS_IS_ALIGNED (Address, Alignment) @normalize_aligned disable paren expression@ expression E, SZ; @@ ( - (IS_ALIGNED (E, SZ)) + IS_ALIGNED (E, SZ) | - (!IS_ALIGNED (E, SZ)) + !IS_ALIGNED (E, SZ) ) @normalize_macro_args disable paren expression@ expression E, SZ; @@ ( - IS_ALIGNED ((E), SZ) + IS_ALIGNED (E, SZ) | - IS_ALIGNED (E, (SZ)) + IS_ALIGNED (E, SZ) ) ``` Signed-off-by: Mingjie Shen

EmulatorPkg/SecPeiServicesLib: Prevent overread with available size macros

2026-04-13T14:12:17+00:00

Symptom:Unsafe typecasting may lead to out‑of‑bound memory access RootCause: FileSize, FileLength and SectionLength are declared as UINT32 and masked with 0x00FFFFFF to store only the lower 24 bits. Although this approach yields the correct result, it introduces a potential risk due to unsafe typecasting and dereferencing. Solution: Using the predefined macro FFS_FILE_SIZE() and SECTION_SIZE from MdePkg\Include\Pi\PiFirmwareFile.h, which safely performs the same operation by reconstructing the size using individual byte access. This commit also addresses the fix for coverity issue "OVERRUN" Cc: Sachin Ganesh Signed-off-by: Gowtham M

EmulatorPkg: Clear DLINK_XIPFLAGS

2026-04-11T00:40:10+00:00

Clear DLINK_XIPFLAGS to disable use of alignment flags for all tool chains. Setting alignment flags other than the OS application defaults are not required for EmulatorPkg builds. Add and/or clarify comments to explain the overrides to the default firmware build configurations required for EmulatorPkg.dsc builds. Align Mingw CLANGDWARF to GCC by moving the application libraries into DLINK2_FLAGS. Signed-off-by: Michael D Kinney

EmulatorPkg: Add Windows CLANGPDB CI

2026-04-10T21:11:58+00:00

CLANGPDB build of EmulatorPkg is supported on Windows, but not Linux. In order to complete CLANGPDB CI, introduce an Azure pipelines file to run this build. The file is a duplicate of current Windows-VS.yml in the same directory simply with the toolchain changed, similar to the approach taken in recent commits to add Ubuntu CLANGDWARF and CLANGPDB CI.

EmulatorPkg: Remove EmulatorPkg from CLANGPDB CI

2026-03-17T15:52:22+00:00

EmulatorPkg currently fails to build under CLANGPDB with link time errors. Since EmulatorPkg is a legacy package which is currently not being built with CLANGPDB, it is considered simpler to simply exclude this. Signed-off-by: Mike Beaton
