https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=269823 --- Comment #6 from Mina Galić <freebsd@igalic.co> --- n.b.: virtio_random is the only call-site of virtqueue_poll() that passes something other than NULL to the *len parameter: sys/dev/virtio/console/virtio_console.c 988: virtqueue_poll(vq, NULL); 1382: virtqueue_poll(vq, NULL); sys/dev/virtio/random/virtio_random.c 288: virtqueue_poll(vq, &rdlen); sys/dev/virtio/block/virtio_blk.c 1442: virtqueue_poll(vq, NULL); sys/dev/virtio/network/if_vtnet.c 3526: virtqueue_poll(vq, NULL); tho i don't see how that would influence it. -- You are receiving this mail because: You are on the CC list for the bug.home | help
