4: Some Alpha AXP OSF/1 binaries directly use the facilities provided by
5: the Mach kernel that is the basis for OSF/1. These include (but are
6: surely not limited to) 'dd', 'ps', and 'w'.
7:
8: Invariably, the symptom that these binaries display is that they crash
9: with an "unimplemented system call" trap (SIGSYS signal) for a syscall
10: that has a negative number. In general, binaries that use the Mach
11: syscalls appear to invoke task_self() as their first syscall.
12:
13: The name, number, and number of arguments for each Mach syscall is
14: given below; this information was gleaned by looking through the OSF/1
15: libmach.a's object files with dbx, then double-checked against the
16: contents of OSF/1's <mach/syscall_sw.h>.
17:
18: These calls would be very difficult to implement properly in the
19: OSF/1 emulation code; by its very nature, NetBSD is not Mach, and we
20: don't and can't provide the underlying facilities that it does.
