I copied the GENERIC to SIFIVE-COMPAT11 and then : 

enceladus# pwd
/usr/src/sys/riscv/conf
enceladus# 

enceladus# grep -E 'COMPAT_FREEBSD1?' SIFIVE-COMPAT11
options         COMPAT_FREEBSD11        # Compatible with FreeBSD11
options         COMPAT_FREEBSD12        # Compatible with FreeBSD12
options         COMPAT_FREEBSD13        # Compatible with FreeBSD13
options         COMPAT_FREEBSD14        # Compatible with FreeBSD14
enceladus# 

This will take a few days. The SiFive Unmatched Rev B board is amazingly slow.

Oh, also, I have already done a stop-start-curse cycle because I forgot
this lovely LLVM/Clang gack :

enceladus# diff -u lib/clang/llvm.build.mk.orig lib/clang/llvm.build.mk

Anyways ... we are looking at days and days before this completes.

That should be *if* it completes a build.
