The MMTests benchmarking
system is normally associated with its initial use case: testing
memory-management changes. Increasingly, though, MMTests is not limited to
memory management testing; at the 2020 Power Management and Scheduling
in the Linux Kernel summit (OSPM), Dario Faggioli talked about how he
is using it to evaluate changes to the CPU scheduler, along with a
discussion of the changes he had to make to get useful results for systems
hosting virtualized guests.
