Also sync ->head when moving slots in netmap_sw_to_nic(). * Remove a crashing selrecord() call. * Unclog the logic surrounding netmap_rxsync_from_host(). * Add timestamping to RX host ring. * Remove a couple of obsolete comments.

See details in the log for svn 261909. 2013-06-05T17:27:59Z Luigi Rizzo luigi@FreeBSD.org 2013-06-05T17:27:59Z urn:sha1:85233a7d39f577ef5cf55fac2b090d4bc32960bf from each batch flowing on the VALE switch - feature: add glue for 'indirect' buffers on the sender side: if a slot has NS_INDIRECT set, the netmap buffer contains pointer(s) to the actual userspace buffers, which are accessed with copyin(). The feature is not finalised yet, as it will likely need to deal with some iovec variant for proper scatter/gather support. This will save one copy for clients (e.g. qemu) that cannot use the netmap buffer directly. A curiosity: on amd64 copyin() appears to be 10-15% faster than pkt_copy() or bcopy() at least for sizes of 256 and greater. 2013-05-30T14:07:14Z Luigi Rizzo luigi@FreeBSD.org 2013-05-30T14:07:14Z urn:sha1:f18be5766f1c00051020f9f5b174db57e74f437e - the VALE switch now support up to 254 destinations per switch, unicast or broadcast (multicast goes to all ports). - we can attach hw interfaces and the host stack to a VALE switch, which means we will be able to use it more or less as a native bridge (minor tweaks still necessary). A 'vale-ctl' program is supplied in tools/tools/netmap to attach/detach ports the switch, and list current configuration. - the lookup function in the VALE switch can be reassigned to something else, similar to the pf hooks. This will enable attaching the firewall, or other processing functions (e.g. in-kernel openvswitch) directly on the netmap port. The internal API used by device drivers does not change. Userspace applications should be recompiled because we bump NETMAP_API as we now use some fields in the struct nmreq that were previously ignored -- otherwise, data structures are the same. Manpages will be committed separately. 2013-05-02T16:01:04Z Luigi Rizzo luigi@FreeBSD.org 2013-05-02T16:01:04Z urn:sha1:654ae8d68c0a79dfa51d1279de2bac7bebda6dae 2013-04-30T16:08:34Z Luigi Rizzo luigi@FreeBSD.org 2013-04-30T16:08:34Z urn:sha1:849bec0e760b99364545f0b4d570ed60767a1475 - netmap_rx_irq()/netmap_tx_irq() can now be called by FreeBSD drivers hiding the logic for handling NIC interrupts in netmap mode. This also simplifies the case of NICs attached to VALE switches. Individual drivers will be updated with separate commits. - use the same refcount() API for FreeBSD and linux - plus some comments, typos and formatting fixes Portions contributed by Michio Honda 2013-04-29T18:00:53Z Luigi Rizzo luigi@FreeBSD.org 2013-04-29T18:00:53Z urn:sha1:d4b42e08696b1dc7089bfd21edd6f0f621f30b0d remove $Id$ lines, and add blank lines around some #if / #elif /#endif 2013-04-19T21:08:21Z Luigi Rizzo luigi@FreeBSD.org 2013-04-19T21:08:21Z urn:sha1:2579e2d715f7a6d1731587402dce0b2c01c9eeea - remove vestiges of the old memory allocator - clean up some comments
