That is oversimplified to the point of being wrong. As of HEAD r239255 and 9-stable r240097, there's no longer a limit on amd64. The limit is still required on 32-bit architectures due to the limited KVA available. The actual KVA requirements (RAM is only allocated when the swap space is actually used) is about 5MB KVA per 1GB swap. The default swzone for i386 was 32MiB - which is sufficient for ~7GB swap (the 1852656 pages reported above) and was increased to 34.5MB for i386 in r239730 to support ~8GB swap (this is also in r240097). (It's all approximate because of the way swap space is allocated using struct swblock).

If a VALE switch was a pseudo interface and you added real interfaces to it then it would be consistent with the current networking fu.

sysctl-controlled key-value store ?
Hi, in order to control some netmap feature (namely, which interfaces are attached to VALE switches), i would considering the use of a sysctl interface triggering a sysctl-proc, something of the form dev.netmap.switch.xyz=em0 ix1 dev.netmap.switch.foo=ix2 re0 where "xyz" and "foo" are the names of the netmap switch instances. Thing is, right now those names are created dynamically when users configure a netmap port, and I would like to have the same dynamic behaviour with the sysctl, so that an access to a not-yet-existent dev.netmap.switch.xyz node should both create the node and add a value. Is this possible (either now or with a modest modification to the sysctl infrastructure) ? Or should I use a workaround, say have a sysctl node that acts as a 'gate' and the procedure will create (readonly) values e.g. dev.netmap.switch.config="xyz: em0 ix1" # creates dev.netmap.switch.xyz=em0 ix1 dev.netmap.switch.config="xyz: ix1" # updates dev.netmap.switch.xyz=ix1 dev.netmap.switch.config="xyz:" # deletes dev.netmap.switch.xyz= cheers luigi ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"

If there is a clean way to do this without modifying the src/ tree prior to the build phase, I am happy to also provide bootonly.iso images and the necessary hierarchy for the various distribution sets.
