Well, GCC 15 already ended support for the nios2 soft-core. The successor to it is Nios V which runs RISC-V. If users want us update the kernel, they'll also need to update their FPGA.
Microblaze also is a soft-core, based on RISC-V, presumably it could support actual RISC-V if anyone cared.
All others haven't received new hardware within the last 10 years, everybody using these will already be running an LTS kernel on there.
It looks like there really are no reasons not to require rust for new versions of the kernel from now on then!
Is this the same NIOS that runs on FPGA? We wrote some code for it during digital design in university, and even an a.out was terribly slow, can't imagine running a full kernel. Though that could have been the fault of the hardware or IP we were using.
You fell into the trap I predicted a few years ago when the renaming happened. Microblaze refers to the old microblaze soft core, not the new one that they named the same thing and that is based on RISCV.
