Since then we've been able to build riscv32 stages for Gentoo just fine using qemu-user, see https://www.gentoo.org/downloads/#riscv Cheers, Andreas commit f0907ff4cae743f1a4ef3d0a55a047029eed06ff Author: Richard Henderson <richard.hender...@linaro.org> AuthorDate: Fri Apr 5 11:58:14 2024 -1000 Commit: Richard Henderson <richard.hender...@linaro.org> CommitDate: Tue Apr 9 07:43:11 2024 -1000 linux-user: Fix waitid return of siginfo_t and rusage The copy back to siginfo_t should be conditional only on arg3, not the specific values that might have been written.
