fwk: SCP suspend execution until an interrupt occurs (!617) · Merge requests · Firmware / SCP-firmware

Darryl Green requested to merge github/fork/girishpathak/wfe into master Mar 11, 2022

Created by: girishpathak

Currently, the firmware is busy looping forever while waiting for any interrupts. This behaviour consumes power unnecessarily. To avoid the busy loop scenario the firmware will enter suspend state using WFE (Wait For Event) instruction. Any interrupt will wake up the CPU to handle new events.
