The driver provides support for AMD Power Management Controller
primarily responsible for S2Idle transactions that are driven from
a platform firmware running on SMU. This driver also provides a debug
mechanism to investigate the S2Idle transactions and failures.
Say Y or M here if you have a notebook powered by AMD RYZEN CPU/APU.
If you choose to compile this driver as a module the module will be
called amd-pmc.

help
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.
