Re: sending messages, user process <--> kernel module

[Matthew Dillon <dillon@xxxxxxxxxxxxxxxxxxxx>]

:recently there was a question on freebsd-hackers, on how to send async from
:kernel to userspace (and vice versa).
:
:is our leightweight messaging able to do this (with only moderate work
:needed)?
:according to the lwkt_ prefix it is not intended.
:
:but as lwkt messaging has been ported to userspace...
:
:btw: i am aware of other possiblities, i am just curious, whether this is
:possible.

:~ibotty

    The answer is yes, the intention of the LWKT syscall messaging is to
    be able to do this.  It doesn't do it yet... that is, right now system
    call messages are executed synchronously, but it will eventually.

    It isn't easy, though... it's a lot more then just a moderate amount 
    of work.
