UefiPayloadPkg/DxeHobLib: Add lazy initialization for gHobList

2026-07-21T02:14:02+00:00

This change adds dynamic initialization of gHobList in GetHobList() to handle cases where library constructors are executed before DxeHobListLibConstructor. Issue: On ARM platforms using ArmMmuBaseLib, the ArmMmuBaseLibConstructor calls GetFirstGuidHob() before xeHobListLibConstructor has initialized gHobList, causing an ASSERT. Root Cause: ArmMmuBaseLib's constructor uses HobLib functions, but UefiPayloadPkg's DxeHobLib assumes gHobList is already initialized by DxeHobListLib's constructor. Solution: Add the same lazy initialization pattern already used in MdePkg/Library/DxeHobLib, which dynamically retrieves the HOB list from the System Configuration Table if gHobList is NULL. This change: - Aligns behavior with MdePkg/Library/DxeHobLib - Has no impact on existing functionality - Improves robustness for ARM platforms Signed-off-by: Jared Pan

UefiPayloadPkg: 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 UefiPayloadPkg/UefiPayloadPkg.dsc, which builds PartitionDxe. Out-of-tree platforms consuming either module need the same one-line resolution. Signed-off-by: Richard Lyu

UefiPayloadPkg: Fix incorrect EfiPciWidth* enum literals

2026-07-14T00:06:22+00:00

In arguments of EFI_PCI_IO_PROTOCOL member functions, replace the EfiPciWidth* enum literals from EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL_WIDTH with the matching EfiPciIoWidth* values from EFI_PCI_IO_PROTOCOL_WIDTH. This keeps the call sites aligned with the protocol they actually use. The old values were copied from EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL code, so they obscured the intent of the calls and relied on an explicit cast. This mimics commit 8ba64a9a9417 ("UefiPayloadPkg: Fix build failure with CLANGPDB"). Generated by coccinelle script. ``` smpl @initialize:python@ @@ def to_pci_io_width(name): return name.replace("EfiPciWidth", "EfiPciIoWidth", 1) @normalize@ typedef EFI_PCI_IO_PROTOCOL; typedef EDKII_PCI_DEVICE_PPI; type T =~ "^EFI_PCI_IO_PROTOCOL_WIDTH$"; EFI_PCI_IO_PROTOCOL *x; EDKII_PCI_DEVICE_PPI *y; identifier bad =~ "EfiPciWidth(Uint|FifoUint|FillUint)(8|16|32|64)"; identifier top_op =~ "^(PollMem|PollIo|CopyMem)$"; identifier space =~ "^(Mem|Io|Pci)$"; identifier rw =~ "^(Read|Write)$"; fresh identifier good = script:python(bad) { to_pci_io_width(bad) }; expression first; expression list rest; @@ ( x->top_op | y->PciIo.top_op | x->space.rw | y->PciIo.space.rw ) ( first, - (T)bad + good , rest ) ``` Verified with: - `build -p UefiPayloadPkg/UefiPayloadPkg.dsc -a IA32 -a X64 -b DEBUG -t GCC -D BOOTLOADER=SBL` - temporary IA32 PEIM harness that compiled X86_BuildFdtLib.c Signed-off-by: Mingjie Shen

UefiPayloadPkg: Fix AARCH64's ResetSystemLib class definition

UefiPayloadPkg: 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
