options, status pointer and rusage pointer as arguments. It is up to the caller to copyout the status and rusage to userland if needed. This lets us axe the 'compat' argument and hide all that functionality in owait(), by the way. This also cleans up some locking in kern_wait() since it no longer has to drop locks around copyout() since all the copyout()'s are deferred. - Convert owait(), wait4(), and the various ABI compat wait() syscalls to use kern_wait() rather than wait1() or wait4(). This removes a bit more stackgap usage. Tested on: i386 Compiled on: i386, alpha, amd64 |

$NetBSD: README.mach-traps,v 1.2 1999/03/23 09:19:25 itohy Exp $ $FreeBSD$ Some Alpha AXP OSF/1 binaries directly use the facilities provided by the Mach kernel that is the basis for OSF/1. These include (but are surely not limited to) 'dd', 'ps', and 'w'. Invariably, the symptom that these binaries display is that they crash with an "unimplemented system call" trap (SIGSYS signal) for a syscall that has a negative number. In general, binaries that use the Mach syscalls appear to invoke task_self() as their first syscall. The name, number, and number of arguments for each Mach syscall is given below; this information was gleaned by looking through the OSF/1 libmach.a's object files with dbx, then double-checked against the contents of OSF/1's <mach/syscall_sw.h>. These calls would be very difficult to implement properly in the OSF/1 emulation code; by its very nature, NetBSD is not Mach, and we don't and can't provide the underlying facilities that it does. -- cgd trap name number nargs notes ---- ---- ------ ----- ----- task_self -10 0 thread_reply -11 0 task_notify -12 0 thread_self -13 0 msg_send_old -14 3 msg_receive_old -15 3 msg_rpc_old -16 5 msg_send_trap -20 4 msg_receive_trap -21 5 msg_rpc_trap -22 6 lw_wire -30 3 lw_unwire -31 1 nxm_task_init -33 2 nxm_sched_thread -34 1 nxm_idle -35 1 nxm_wakeup_idle -36 1 nxm_set_pthid -37 2 nxm_thread_kill -38 2 nxm_thread_block -39 1 nxm_thread_wakeup -40 1 inode_swap_preference -40 3 old call? init_process -41 0 map_fd -43 5 nxm_resched -44 2 htg_unix_syscall -52 3 host_self -55 1 host_priv_self -56 1 swtch_pri -59 1 swtch -60 0 thread_switch -61 3 semop_fast -62 4 mach_sctimes_0 -70 0 only if MACH_SCTIMES defined mach_sctimes_1 -71 1 only if MACH_SCTIMES defined mach_sctimes_2 -72 2 only if MACH_SCTIMES defined mach_sctimes_3 -73 3 only if MACH_SCTIMES defined mach_sctimes_4 -74 4 only if MACH_SCTIMES defined mach_sctimes_5 -75 5 only if MACH_SCTIMES defined mach_sctimes_6 -76 6 only if MACH_SCTIMES defined mach_sctimes_7 -77 0 only if MACH_SCTIMES defined mach_sctimes_8 -78 6 only if MACH_SCTIMES defined mach_sctimes_9 -79 1 only if MACH_SCTIMES defined mach_sctimes_10 -80 2 only if MACH_SCTIMES defined mach_sctimes_11 -81 2 only if MACH_SCTIMES defined mach_sctimes_port_alloc_dealloc -82 1 only if MACH_SCTIMES defined
