Linux is not heavily used in safety-critical systems — yet. There is an
increasing level of interest in such deployments, though, and that is
driving a number of initiatives to determine how Linux can be made suitable
for safety-critical environments. At the 2020 Power Management and Scheduling
in the Linux Kernel summit (OSPM), Michal Sojka shone a light on one
corner of this work: testing the thermal characteristics of Linux systems
with an eye toward deployment in avionics systems.
