#### 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.

## Enable snaps on Pop!\_OS and install Processor Feature and Errata Inspector

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.

Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions.

### Enable snapd

Snap can be installed on Pop!\_OS from the command line. Open Terminal from the Applications launcher and type the following:

```
sudo apt update
sudo apt install snapd
```

Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.

### Install Processor Feature and Errata Inspector
