* DynamicTablesPkg: SSDT CPU topology and LPI state generatorPierre Gondois2021-10-085-1/+1407
| | | | | | | | | | | | | | | In the GIC interrupt model, logical processors are required to have a Processor Device object in the DSDT and must convey each processor's GIC information to the OS using the GICC structure. Additionally, _LPI objects may be needed as they provide a method to describe Low Power Idle states that defines the local power states for each node in a hierarchical processor topology. Therefore, add support to generate the CPU topology and the LPI state information in an SSDT table.

* DynamicTablesPkg: AML code generation for a ResourceTemplatePierre Gondois2021-10-081-0/+190
| | | | | | | | | | | | | | | ASL provides a ResourceTemplate macro that creates a Buffer in which resource descriptor macros can be listed. The ResourceTemplate macro automatically generates an End descriptor and calculates the checksum for the resource template. Therefore, add AmlCodeGenResourceTemplate() to generate AML code for the ResourceTemplate() macro. This function generates a Buffer node with an EndTag resource data descriptor, which is similar to the ASL ResourceTemplate() macro.

* DynamicTablesPkg: Helper function to compute package lengthPierre Gondois2021-10-082-2/+132
| | | | | | | | | | | | | | | Some AML object have a PkgLen which indicates the size of the AML object. The package length can be encoded in 1 to 4 bytes. The bytes used to encode the PkgLen is itself counted in the PkgLen value. So, if an AML object's size increments/decrements, the number of bytes used to encode the PkgLen value can itself increment/decrement. Therefore, a helper function AmlComputePkgLength() is introduced to simply computation of the PkgLen.

If a new protocol added in step 2) by other task, e.g. (event timer handle USB device hotplug). The size of protocol database may be increased and cannot fit into the previous buffer in step 3). The protocol database cannot be returned successfully, EFI_BUFFER_TOO_SMALL error will be returned. This patch adds the lock to protect the whole three steps. It can make sure the correct protocol database be returned.

* ArmPkg: SmbiosMiscDxe: Don't populate ExtendedBiosSize when size < 16MBRebecca Cran2021-10-051-3/+4
| | | | | | | | | | | | | | | | | | | | | According to the SMBIOS specification, the ExtendedBiosSize field should be zero when the BIOS size is less than 16MB: "Size (n) where 64K * (n+1) is the size of the physical device containing the BIOS, in bytes. FFh - size is 16MB or greater, see Extended BIOS ROM Size for actual size." Fix the code in MiscBiosVendorFunction.c to only populate the ExtendedBiosSize field if the BIOS size is greater than 16MB. Fix the code to correctly populate the ExtendedBiosSize field with the unit bits set to MB if the size is between 16MB and 16GB.
