-## Expand on the MOpt mutator

-Work on the MOpt mutator that is already in AFL++.
-
-This is an excellent mutations scheduler based on Particle Swarm
-Optimization but the current implementation schedule only the mutations
-that were present on AFL.
-
-AFL++ added a lot of optional mutators like the Input-2-State one based
-on Redqueen, the Radamsa mutator, the Custom mutator (the user can define
-its own mutator) and the work is to generalize MOpt for all the current
-and future mutators.

## perf-fuzz Linux Kernel Module
-Either Port the patch to the upcoming Ubuntu LTS 20.04 default kernel
-and provide a qemu-kvm image or find a different userspace snapshot
-solution that has a good performance and is reliable, e.g. with docker.

-## QEMU 4-based Instrumentation
+## QEMU 5-based Instrumentation
First tests to use QEMU 4 for binary-only AFL++ showed that caching behavior
changed, which vastly decreases fuzzing speeds.
-This is the cause why, right now, we cannot switch to QEMU 4.2.
+In this task test if QEMU 5 performs better and port the afl++ QEMU 3.1
+patches to QEMU 5.
Understanding the current instrumentation and fixing the current caching
issues will be needed.
