What is AGESA on AMD systems?

AGESA is AMD's firmware for Zen CPUs — handles boot, memory init, security. Updates fix bugs, add support.

How to check AGESA version in Linux 7.1?

Boot Linux 7.1+, run `sudo dmesg | grep AGESA`. Version prints on detect.

No — needs this patch, mainline 7.1. Backport possible, but distros lag.

Not fully — UEFI still shows it. But way faster for Linux users.
