Yep! You can run linux even on an entirely open source from hardware to software toolchain: https://github.com/litex-hub/linux-on-litex-vexriscv https://github.com/litex-hub/linux-on-litex-vexriscv Though the FPGA IC itself of course is not open, the bitstream generation is, and there are many fully open source hardware board designs, for example the orangecrab. With a Lattice 85K gate FPGA, you can get 4x 32bit riscv cores at 50Mhz or 1 64bit riscv rocket 64 bit core at 20Mhz
