GNU/Hurd has [1]long struggled with hardware support and [2]is still working on its x86_64 support while having [3]a host of various hardware limitations but it also appears they are eager to explore Hurd on RISC-V platforms.

Following this week's [4]GCC 15 compiler code branching and GCC 16 development opening on main, one of the early features for next year's GNU Compiler Collection release is introducing riscv*-*-gnu* targets.

[5]This commit for GCC 16 is enough to get a compiler toolchain in place that can build binaries targeting the RISC-V processor architecture on GNU Hurd.

While RISC-V is more open than other CPU ISAs, as recently as two years ago Hurd developers were apprehensive about it and instead exploring AArch64 ports and the like due to being better established than RISC-V. We'll see if GNU Hurd on RISC-V sees much uptake moving forward and ultimately what RISC-V boards end up seeing support under GNU/Hurd.
