CPU instruction set flags, ELF AT_HWCAP vector & errata inspector
Processor Feature and Errata Inspector is a desktop hardware capability, ELF auxiliary vector, simultaneous multithreading (SMT), and kernel CPU errata status viewer for Linux. An independent Linux alternative inspired by desktop processor feature utilities, it reads live kernel interfaces to inspect supported instruction set extensions, memory addressing limits, dynamic loader capability bitmasks, and active microarchitectural errata controls.
Key Features:
- ELF Auxiliary Vector Decoder (/proc/self/auxv): Reads and decodes AT_HWCAP, AT_HWCAP2, AT_PAGESZ, AT_CLKTCK, AT_PLATFORM, AT_MINSIGSTKSZ, AT_SYSINFO_EHDR, and program header entries passed directly from the Linux kernel to user-space processes.
- CPU Instruction Set & Microarchitecture Catalog (/proc/cpuinfo): Categorizes active SIMD vector extensions (SSE, AVX, AVX2, FMA), cryptographic instructions (AES-NI, SHA, VAES, RDRAND), paging and cache features, physical/virtual address widths, microcode revision, cache alignment, and per-thread clock frequencies.
- SMT & Kernel CPU Errata Telemetry (/sys/devices/system/cpu): Displays real-time SMT state and kernel-reported CPU hardware errata mitigation mechanisms alongside processor category distribution charts.
- Structured Reports: Exports complete processor capability, auxiliary vector, and errata tables to CSV and JSON files.
