In linux kernel since version 4.19.318 (release Date: 2024-07-18)  
AMD MP2 STB function provides a data buffer used to log debug
information about the system execution during S2Idle suspend/resume.
A data buffer known as the STB (Smart Trace Buffer) is a circular
buffer which is a low-level log for the SoC which is used to debug
any hangs/stalls during S2Idle suspend/resume.

Creates debugfs to get STB, a userspace daemon can access STB log of
last S2Idle suspend/resume which can help to debug if hangs/stalls
during S2Idle suspend/resume.
