Synopsis

typedef struct dmi_processor_aarch64_data {
    dmi_processor_revision_t revision;
    dmi_byte_t length;
    dmi_byte_t __reserved;
    dmi_word_t vendor_id;

} dmi_processor_aarch64_data_t;

Description

The dmi_processor_aarch64_data_t structure describes the processor-specific data of the processor additional information structures (type 44) of 64-bit Arm (AArch64) processors: a header naming the vendor of the processor and the sub-type of the data, followed by the data of the sub-type. A system has at most one structure of each sub-type.

The structure is packed: it has no padding, and its fields are laid out as in the data, whose multi-byte values are little-endian. The decoder does not use it: it may be laid over the data field of dmi_processor_ex_t to read the processor-specific data, once its architecture and length have been checked.

Fields

revision

Revision of the format of the data, 1.0 at present.

length

Length of the processor-specific data, in bytes: the 8 bytes of the header and the length of the sub-type specific data.

__reserved

Reserved, zero.

vendor_id

JEP-106 code of the vendor of the processor or of the silicon provider: the bank index in bits 14:8, and the identification code with its parity bit in bits 7:0. Bit 15 is zero.

subtype

Sub-type of the data, one of the dmi_processor_aarch64_data_subtype_t values.

__reserved2

Reserved, zero.

subtype_specific_data

Data of the sub-type: AArch64 architecture data (dmi_processor_aarch64_arch_data), or data defined by the vendor.
