Are there any version requirements, or additional qemu patches, that
need to be taken into account. Should I expect to see output on stdio?
I tried to build hss 3faaaaf8ce0d, using
https://github.com/riscv/riscv-gnu-toolchain (7f1f4ab5b0e0), which
ends up being a gcc 10.1. That caused me to raise
https://github.com/polarfire-soc/hart-software-services/issues/2.
Suppressing that warning gets me a hss.bin, but neither that, nor one
I build with Debian's 8.3 riscv64-linux-gnu- produces any output when
I apply this set on top of 39335fab59. (Even when I change the wait to
nowait.)
