Hi guys,

I am an happy switcher from vxworks to linux on a MPC8560. I would like
to probe a read or write access to the address of a peripheral. If I
were using vxworks, I would do a vxMemProbe.
When using Linux, what should I use:
- in kernel space ? ( ?? )
- in user space ? (install a signal handler ?)

I don't want to check the validity of the acces (read/write) from a MMU
point of view (for that I have the macro access_ok in
include/asm/uaccess.h) but to install on the fly a bus error handler and
get cleanly the result of the read or write access.

Thanks for your help,
