The Linux 5.12 merge window is drawing to a close this weekend while being sent in this morning were the RISC-V updates that tend to excite the free software enthusiasts.
Notable with RISC-V in Linux 5.12 is initial support for the SiFive FU740, the SoC design announced at the end of last year. The most notable major user coming to market at the moment with the FU740 is the HiFive Unmatched development board. The SoC with its quad-core U74-MC and single S7 embedded core is joined by four USB 3.2 Gen 1 ports, PCI Express x16 (at x8 speeds), NVMe M.2, Gigabit Ethernet, and 16GB of RAM to make for the most interesting RISC-V development board to date. The HiFive Unmatched is slated to still begin shipping later this quarter for about $665 USD.
