Hi all,
I am doing a port of a shared library; in this library , a shared memory
segment is being mapped (now using the Xenomai POSIX skin.)
Some semaphores and data are placed on that shared segment.
Is there a way to mark the shared memory segment for deletion (unlink) after
the last process

Please could I get some background with respect of the possible causes of this
message? I have read it might be related to __copy_to/from user but I have
already validated that path in the driver. Must be something else.
Also, I am OK to assume that the system is not reliable after this event.

Typical PCI devices have many sources of interrupts (some level, some edge
triggered) normally all routed through PIN A.
When writing an RTDM pci driver for one of these devices, how does the
microkernel manage the edge interrupts?
I am looking at some traces where the CPU seems to be interrupt

Is there an API to switch domains from a user RT task and a kernel based task?

For what purpose
On a Xenomai multi-threaded application, I need to access the process list of
virtual memory areas in an rtdm driver.
Since this region is protected by mmap_sem, I am unsure how to perform the
access.
Any guidance will be appreciated.
thanks
Jorge
