since linux was originally going to be called Freax, I may as well do it myself
idk like use whatever package manager u use install qemu-system-riscv32 and probably opensbi seeing as thats like the bios
then run make run and it should work
oh yea i use llvm tools so u gonna want like the llvm suite of tools installed and clang and of course make sure it supports riscv you can check by running clang --print-targets and in the list there should be riscv if not then ur outta luck
yea thats about it bruh
