Add a comment about an alternative to \usepackage{underscore}, in case we'll want to use it in the future. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> git-svn-id: https://tools.oasis-open.org/version-control/svn/virtio@116 0c8fb4dd-22a2-4bb5-bc14-6c75a5f43652

2013-11-25txt2latex.pl: script to convert text to latexmstsirkin
The result compiles and looks kind of OK. This reverse-engineers our txt format to generate the initial latex file. Tables are included in verbatim sections. Code is included in listing sections. Math is escaped with $$. TODO (possibly manually): - remove extra sections at the beginning of the document - format tales using tabular or similar environment - format lists using itemize/enumerate/description - prevent hyphenation in the middle of identifiers Signed-off-by: Michael S.

2013-11-25virtio: add latex templates from CMISmstsirkin
I imported latex templates from the CMIS specifications and changed s/CMIS/VIRTIO/ everywhere. The result is very close to one produced by exporting from the ODF we were supplied, with the exception of the TOC formatting, where section numbers are in blue instead of black, and major sections don't have dots leading to page numbers. I'm guessing this isn't very important, someone with more latex knowledge can try to figure this out. Generating html doesn't actually work for me. It doesn't work for me for CMIS either, so it's probably just an issue with my local latex setup. I'm not sure we need html output at all. Signed-off-by: Michael S.

2013-10-31Configuration (read) atomicity.rusty
Aka issue VIRTIO-35. This is solved per transport: 1) PCI: use the 8 bit reserved field.
