Pull Request Overview

Adds support for AWS Graviton 4 by renaming architecture strings and extending CPU definitions.

• Switch comments and fields from “arm64” to “aarch64” for consistency
• Hyphenate existing Neoverse microarchitecture names
• Introduce a new Neoverse-V2 entry for AWS Graviton 4

• The comment was updated to use “aarch64”; please ensure any external documentation or processing logic (e.g., environment checks) is updated to match this new identifier.

Architectures  []string // architectures, i.e., x86_64, aarch64. If empty, it will run on all architectures.

internal/report/table_defs.go:53

• Similarly update any reporting code or documentation that parses architecture strings to recognize “aarch64” instead of “arm64”.

Architectures []string // architectures, i.e., x86_64, aarch64. If empty, it will be present for all architectures.

• The microarchitecture names were hyphenated (e.g., Neoverse-N1); verify that any lookup or display logic depending on the old names is updated accordingly.

{MicroArchitecture: "Neoverse-N1", Family: "", Model: "1", Stepping: "r3p1", Architecture: "aarch64", MemoryChannelCount: 8, LogicalThreadCount: 1, CacheWayCount: 0}, // AWS Graviton 2

internal/report/cpu_defs.go:78

• A new CPU entry for Neoverse-V2 was added; consider adding or updating tests to cover detection and reporting of this new architecture.

{MicroArchitecture: "Neoverse-V2", Family: "", Model: "1", Stepping: "r0p1", Architecture: "aarch64", MemoryChannelCount: 8, LogicalThreadCount: 1, CacheWayCount: 0}, // AWS Graviton 4
