writing a new trap handler
Hi,
I looked at the pid provider''s trap handler code
(usr/src/uts/sun4u/ml/trap_table.s and
usr/src/uts/sun4/os/dtrace_subr.c), and try to understand how it works.
Can someone point me some directions about trap handlers? I am interesed
in writing a new one (like dtrace does it in pid provider with the 0x38
trap id). At first, I would be pleased if I could write a trap handler
which just enters kernel mode, does nothing...
