DynamicTablesPkg: Add AmlLib logical equality generator

2026-09-10T10:21:41+00:00

Add AmlCodeGenEqual() to create an AML LEqual expression from two supplied operands. Use the existing AML_METHOD_PARAM representation for integer, method argument, and local variable operands. The generated equality expression can be used as a predicate by control-flow objects. Signed-off-by: Varshit Pandya

DynamicTablesPkg: Add AmlLib If code generator

2026-09-10T10:21:41+00:00

Add AmlCodeGenIf() to create an AML If object from a supplied predicate node. The API takes ownership of the predicate and returns an If node to which executable statements can subsequently be appended. Signed-off-by: Varshit Pandya

DynamicTablesPkg: Add AmlLib Store generator

2026-09-10T10:21:41+00:00

Add AmlCodeGenStoreToName() to create an AML Store operation with a typed source operand and a named target. Support integer, method argument and local variable sources using the AML_METHOD_PARAM representation. Append the generated Store node to an optional parent object. Signed-off-by: Varshit Pandya

DynamicTablesPkg: Add AmlLib NamedField code generator

2026-09-10T10:21:41+00:00

Add AmlCodeGenFieldElemNamed() to create a named element within an AML Field list. The API validates the supplied NameSeg and field length, encodes the length using the AML FieldPkgLen format, and appends the resulting NamedField node to its parent Field object. Signed-off-by: Varshit Pandya

DynamicTablesPkg: Add AmlLib ReservedField code generator

2026-09-10T10:21:41+00:00

Add AmlCodeGenFieldElemReserved() to create an AML ReservedField element and append it to a Field list. The API accepts the reserved range length in bits and validates that the parent supports a Field list. ReservedField elements describe unnamed gaps in Field declarations and can be used when translating ASL Offset() declarations. Signed-off-by: Varshit Pandya

DynamicTablesPkg: Add AmlLib Field code generator

2026-09-10T10:21:41+00:00

Add AmlCodeGenField() to create an empty AML Field object associated with an OperationRegion. Expose access type, lock rule, and update rule through typed public enumerations and encode them in the Field flags byte. The generated Field node can be attached directly to a parent or returned so that field elements can subsequently be appended. For example, the API can generate: Field (REG0, DWordAcc, NoLock, Preserve) { } Signed-off-by: Varshit Pandya

DynamicTablesPkg: Add AmlLib OperationRegion code generator

2026-09-10T10:21:41+00:00

Add AmlCodeGenOperationRegion() to create an AML OperationRegion object from a region name, address space, integer offset, and integer length. The API creates the OperationRegion object and populates its four fixed AML operands: - RegionName - RegionSpace - RegionOffset - RegionLength RegionOffset and RegionLength are encoded using the smallest suitable AML integer representation. The generated node can either be attached directly to a supplied parent or returned to the caller for later use. For example, the API can generate an object equivalent to: OperationRegion ( REG0, SystemMemory, RegionOffset, RegionLength ) This provides generators with a reusable way to describe register regions without relying on a precompiled ASL template.

DynamicTablesPkg: Expose AmlLib Notify generator

2026-09-10T10:21:41+00:00

Make AmlCodeGenNotify() public and declare it in AmlLib.h. Add the new API to the CodeGen documentation group. Callers currently cannot append an individual Notify operation while incrementally constructing a method body. For example, this enables generators to construct _EVT methods containing conditional register writes and device notifications. Signed-off-by: Varshit Pandya

DynamicTablesPkg: Document AmlLib code generator APIs

2026-09-10T10:21:41+00:00

Add AmlCodeGenMethod() and other missing public functions to the CodeGen API documentation group. Signed-off-by: Varshit Pandya

DynamicTablesPkg/AmlLib: Add AmlCodeGenMethodRetBuffer API

2026-07-31T12:56:11+00:00

Add support for generating AML methods that return a buffer through the new AmlCodeGenMethodRetBuffer() API. Signed-off-by: Tuan Phan
