Thanks Jan.

Another thought: is there a direct Adeos =A0call to enable/disable all=20
interrupts, with nesting from user space?

I'm porting some legacy RTAI code to the Xenomai native skin. =A0The RTAI c=
ode=20
has rtai_save_flags_and_cli()/rtai_restore_flags() for enabling/disabling a=
ll=20
interrupts =A0direct from user space, with capability to handle nested call=
s. =A0

Yes, please add this to the native skin "wish list", along with a nesting=20
capability.

=A0=A0=A0=A0=A0=A0=A0=A0thanks,
=A0=A0=A0=A0=A0=A0=A0=A0Jeff
