Elia, a security= researcher at Qualcomm is exploring ways to fuzz some hexagon OS kernel wi= th QEMU and in particular leveraging snapshotting, inspired by your researc= h and more. I'm not an expert on the details, but I'd like to make an intr= oduction and see if there's an opportunity for us to learn from one another= =2E Maybe we can have a call to kick things off? Hi Brian and Elia, Alexander investigated ways to reset state between fuzzing runs and has experience in this area. I suggest talking to him about it.
