I agree the naming is annoying. However the extensions aren't too hard to understand. They are much more regular than on other architectures. I wrote a deep dive into them here: https://research.redhat.com/blog/article/risc-v-extensions-whats-available-and-how-to-find-it/ https://research.redhat.com/blog/article/risc-v-extensions-w...
