DynamicTablesPkg/AcpiFadtLib: Preserve platform flags on Arm and RISC-V

2026-09-25T15:32:56+00:00

BuildFadtTable() adds platform-provided fixed-feature flags before calling FadtArchUpdate(). The Arm and RISC-V implementations assign Fadt->Flags, discarding the flags already added by the platform. Use bitwise OR assignment to add architecture defaults without overwriting the existing flags. Leave the generation order, validation masks, ACPI revision handling, and architecture defaults unchanged. Signed-off-by: Djordje Nedic

DynamicTablesPkg/AmlLib: Fix root node cleanup leak

2026-09-23T12:23:44+00:00

AmlCreateRootNode() calls AmlDeleteRootNode() when SDT header allocation fails. However, AmlDeleteRootNode() rejects a NULL header and returns without freeing the root node, leaking the node allocation. Allow AmlDeleteRootNode() to handle a NULL SDT header and always free the root node. Signed-off-by: Amrathesh

DynamicTablesPkg/AmlLib: Fix data node cleanup leak

2026-09-23T12:23:44+00:00

AmlCreateDataNode() calls AmlDeleteDataNode() when buffer allocation fails. However, AmlDeleteDataNode() rejects a NULL buffer and returns without freeing the data node, leaking the node allocation. Allow AmlDeleteDataNode() to handle a NULL buffer and always free the data node. Signed-off-by: Amrathesh

DynamicTablesPkg/AmlLib: Fix fixed argument bounds check

2026-09-23T12:23:44+00:00

AmlSetFixedArgument() accepts an index equal to the fixed argument count. The count is an exclusive upper bound, so this permits an out-of-bounds write to the FixedArgs array. Require the index to be strictly less than the fixed argument count. Signed-off-by: Amrathesh

DynamicTablesPkg/AmlLib: Fix serialization buffer size handling

2026-09-23T12:23:44+00:00

AmlSerializeTree uses a reversed buffer size comparison. As a result, it returns success without serializing when the buffer is larger than needed and attempts serialization when the buffer is too small. Return EFI_BUFFER_TOO_SMALL when Buffer is NULL or the supplied buffer is too small, and always report the required size. Update AmlSerializeDefinitionBlock to handle the expected size query status.

DynamicTablesPkg: Add ACPI ERST table generator

2026-09-18T17:22:49+00:00

Add a common Error Record Serialization Table (ERST) generator based on the ACPI 6.6 definition. Introduce an architecture-common Configuration Manager object to provide serialization instruction entries. Validate actions, instructions, flags, register masks, action grouping, and GOTO targets before generating the table. Signed-off-by: Amrathesh

DynamicTablesPkg: Add ACPI BERT table generator

Add a common Boot Error Record Table (BERT) generator based on the ACPI 6.6 definition. Introduce an architecture-common Configuration Manager object that provides the boot error region address and length. Signed-off-by: Amrathesh
