Linux Kernel Developers Begin Figuring Out Vendor-Specific RISC-V Code

With the increasingly popular RISC-V open-source processor instruction set architecture (ISA), there is the possibility for vendor-specific instruction set extensions. At this point the kernel has no infrastructure in place for its RISC-V port to allow for such bits, but that is being worked on as part of bringing up AndeStar RISC-V CPUs under the Linux kernel...
