There are around 710 tests for amd64 and around 650 tests for i386. When everything is compiled with GCC then I get a bit less than 20 failures on amd64. The figure goes up to about 60 failures for i386 and building everything with clang. I’m still working through the i386 and clang related issues.

I’m tracking issues on GitHub as they are analysed.

There’s a fairly large number of syscalls that predate FreeBSD 10 and are not implemented. Here are the ones added in FreeBSD 10 or later that aren’t implemented.

    // futimens                                 546
    // utimensat                                547
    /* 548 is obsolete numa_getaffinity */
    /* 549 is obsolete numa_setaffinity */
    // fdatasync                                550
    // fstatat                                  552
    // fhstat                                   553
    // getdirentries                            554
    // mknodat                                  559
    // kevent                                   560
    // cpuset_getdomain                         561
    // cpuset_setdomain                         562
    // getfhat                                  564
    // fhlink                                   565
