Ski accepts but ignores the system calls shown in Table 7-2.For those that return an error indication, the errno code is shown in parentheses. All other ignored system calls return with a success indication, having done nothing.

Table 7-2. Linux System Calls Accepted but Ignored by Ski

_sysctl (ENOSYS)	bdﬂush ( ENOSYS)	capget	capset
create_module (ENOSYS)	delete_module (ENOSYS)	get_kernel_syms (ENOSYS)	getpmsg
init_module (ENOSYS)	msgctl (ENOSYS)	munlockall	nfsservctl
prctl	ptrace (EOPNOTSUPP)	putpmsg	query_module (ENOSYS)
quotactl (ENOSYS)	rt_sigqueueinfo	rt_sigtimedwait	semctl (ENOSYS)
sendﬁle	shmctl ( ENOSYS)	sysfs (ENOSYS)	sysinfo (ENOSYS)

All other system calls are unsupported. When an IA-64 application-mode program makes an unsupported system call, the simulator stops the simulation and displays an error message.
