virtio_balloon: use simplified virtqueue accessors.

2013-03-20T05:15:06Z

We never add buffers with input and output parts, so use the new accessors. Signed-off-by: Rusty Russell

virtio_ring: virtqueue_add_outbuf / virtqueue_add_inbuf.

2013-03-20T05:14:52Z

These are specialized versions of virtqueue_add_buf(), which cover over 80% of cases and are far clearer. In particular, the scatterlists passed to these functions don't have to be clean (ie. we ignore end markers). Signed-off-by: Rusty Russell

virtio_ring: virtqueue_add_sgs, to add multiple sgs.

2013-03-20T05:13:29Z

virtio_scsi can really use this, to avoid the current hack of copying the whole sg array. Some other things get slightly neater, too. This causes a slowdown in virtqueue_add_buf(), which is implemented as a wrapper. This is addressed in the next patches. for i in `seq 50`; do /usr/bin/time -f 'Wall time:%e' ./vringh_test --indirect --eventidx --parallel --fast-vringh; done 2>&1 | stats --trim-outliers: Before: Using CPUS 0 and 3 Guest: notified 0, pinged 39009-39063(39062) Host: notified 39009-39063(39062), pinged 0 Wall time:1.700000-1.950000(1.723542) After: Using CPUS 0 and 3 Guest: notified 0, pinged 39062-39063(39063) Host: notified 39062-39063(39063), pinged 0 Wall time:1.760000-2.220000(1.789167) Signed-off-by: Rusty Russell Reviewed-by: Wanlong Gao Reviewed-by: Asias He

virtio_ring: expose virtio barriers for use in vringh.

The host side of ring needs this logic too. Signed-off-by: Rusty Russell

drivers/virtio: remove depends on CONFIG_EXPERIMENTAL

2013-01-11T19:39:04Z

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs. CC: Rusty Russell CC: "Michael S. Tsirkin" Signed-off-by: Kees Cook Acked-by: Rusty Russell
