Hello, I wonder if it is possible to update dummynet code multi-threading capable practically? My idea is below: - A new sysctl tunable will be defined as "net.inet.ip.dummynet.thread_count" (default 1) - To distribute tasks along threads, each sched instance can be assigned to different thread. - By default, all schedulers assigned to thread 0 if no thread_id is set. With a new option named "thr_id" affinity can be set. as below: ipfw sched 1 config type QFQ (by defaut thr_id = 0) ipfw sched 2 config type QFQ thr_id 1 ipfw sched 3 config type QFQ thr_id 2 ipfw sched 4 config type FIFO thr_id 3 ipfw sched 5 config type FIFO thr_id 3 ( sched 4 & 5 assigned to same thread 3 )
I think this approach is more easy then completely rewrite or other solutions. What is the right way to do this? Where to start? I read the explanations in /usr/src/sys/netpfil/ipfw/dummynet.txt On this line below, multiple threads (count can be get from sysctl "net.inet.ip.dummynet. thread_count" tunable) https://github.com/freebsd/freebsd/blob/master/sys/netpfil/ipfw/ip_dummynet.c#L2556 Thanks _______________________________________________ freebsd-ipfw@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ipfw To unsubscribe, send any mail to "freebsd-ipfw-unsubscr...@freebsd.org"
