My application have N balancer thread and M worker thread. Application serve outside interface w/ K rings (and ring size N) and inside interface w/ L rings (and ring size M). All balancer threads share rings from interfaces in next maner: first thread open descriptors to 1st ring of inside and outside interface next thread open descriptors to 2nd ring of inside and outside interface and etc in round-roubin. every balancer thread open 2 pipe to every worker thread. how many if_num, ring_num, buf_num I am need to configure? > 2017-02-16 21:38 GMT+01:00 Slawa Olhovchenkov <s...@zxy.spb.ru>: > > > On Thu, Feb 16, 2017 at 09:14:19PM +0100, Vincenzo Maffione wrote: > > > > > Hi, > > > You're right, we'll try to add more details. > > > > > > In any case, buf_size, ring_size and if_size are the sizes in bytes of > > each > > > buffer, ring and netmap_if (control data structure), respectively. > > > So the maximum amount of slots for each ring is ring_size/16, as 16 is > > the > > > size in bytes of struct netmap_slot. > > > > > > On the other side, buf_num, ring_num and if_num are the total number of > > > biffers, rings and netmap_if objects in each netmap memory area (aka > > > "allocator"). > > > By default there is a single memory area used by all the hardware NICs > > and > > > a separate memory area for each VALE port. > > > This is already configurable, however. > > > > This values also depends on open netmap descriptors, right? > > > > > 2017-02-14 13:36 GMT+01:00 Slawa Olhovchenkov <s...@zxy.spb.ru>: > > > > > > > On Tue, Feb 14, 2017 at 12:26:55PM +0100, Vincenzo Maffione wrote: > > > > > > > > > Hi, > > > > > Have you tried to play with netmap sysctl parameters like: > > > > > > > > > > dev.netmap.buf_num > > > > > dev.netmap.ring_num > > > > > dev.netmap.if_num > > > > > > > > > > those are listed in the sysctl section of the netmap man page. > > > > > > > > man page hide details about calcul rules of this parameters. > > > > > > > > > > > > > > > > -- > > > Vincenzo Maffione > > > > > > -- > Vincenzo Maffione _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
