Examining the Top Five Fallacies About RISC-V

Article note: I went and listened to the RISC V BoF at SC22 a month or so ago, mostly because I wanted to hear what their plans for making the proliferation of extensions manageable for toolchains and libraries looked like... The presented plan included quality choices like "vendor toolchains forked from upstream that support their secret sauce features, but suck at everything else compared to mainline, and are only maintained until until the vendor runs out of VC money," "You can always use the nearest base profile and ignore the special hardware you theoretically paid this vendor a fortune for" and special attention to "Most of your workloads are torch or something anyway, just use the vendor's binaries." I was not impressed.
