Accroding to sys/_types.h: typedef __int64_t __id_t; typedef __int32_t __lwpid_t; typedef __int32_t __pid_t; typedef __int32_t __clockid_t; There is no freebsd32_clock_getcpuclockid2 at all. The 64-bit argument is misplaced in compat32. >How-To-Repeat: >Fix: The PID/TID is encoded in lower 30 bits of clockid. I.e. whole id_t space cannot be used anyway. Please either change signature of syscall to int clock_getcpuclockid2(long id, int which, clockid_t *clock_id); or provide real freebsd32_clock_getcpuclockid2 (); >Release-Note: >Audit-Trail: >Unformatted:
