Thanks Jan.
Another thought: is there a direct Adeos call to enable/disable all
interrupts, with nesting from user space?
I'm porting some legacy RTAI code to the Xenomai native skin. The RTAI code
has rtai_save_flags_and_cli()/rtai_restore_flags() for enabling/disabling all
interrupts direct from user space, with capability to handle nested calls.
Yes, please add this to the native skin "wish list", along with a nesting
capability.
thanks,
Jeff
