"rtt" is "return from trap". We were peacefully executing some code - may be userland, maybe privileged - and took an exception (aka trap) such as an interrupt, page fault etc. When the exception has run to completion we need to resume what we were doing before, and rtt code is the glue that gets us there. It also does a bunch of housekeeping jobs such as checking for signals that need to be delivered to a process we trapped in, see if time quantum on cpu has expired, etc. Gavin _______________________________________________ opensolaris-code mailing list opensolaris-code@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/opensolaris-code
