virtio header resizes in the first I/O region, not in PCI configuration space as the spec v0.8.1 implied. Correct this. Signed-off-by: Michael S. Tsirkin <mst@xxxxxxxxxx> --- I started looking at virtio spec with the view to updating it with new features and possibly documenting more devices. I have used latex in the past but not lyx. As a start, here's a patch to correct a nit in wording. This is just what lyx generated for me, I'd like to get an idea how best to prepare such documentation patches. E.g. do we want change tracking in the document at this stage? Rusty? The patches are agaist initial version from here: http://ozlabs.org/~rusty/virtio-spec/virtio-spec-0.8.1.lyx This is just what google found for me. Is there a repository I should work against instead? virtio-spec.lyx | 13 +++++++++---- 1 files changed, 9 insertions(+), 4 deletions(-) diff --git a/virtio-spec.lyx b/virtio-spec.lyx index 7e39d77..33e8e0a 100644 --- a/virtio-spec.lyx +++ b/virtio-spec.lyx @@ -1,4 +1,4 @@ -#LyX 1.6.2 created this file.
