Re: RISC-V port?
Hi Zach, Thanks. I will work on it. Can we get a ports-riscv list going? I hang out with Shakti RISC-V project guys when possible. I want FreeBSD, NetBSD, OpenBSD running on their boards. I have Sifive Linux and lowRISC linux running on FPGAs. As according to their docs. FreeBSD runs on qemu. We can consider sifive_u machine on qemu as common platform to get all BSDs up. qemu -machine virt first.
