Note that my miniinfo email account no longer exists, but I can still be reached at mmogilvi+qemu@zoho.com if desired. Regarding the patch, I haven't kept up with changes to qemu well enough to really have a useful opinion, although superficially it looks good. Perhaps it would make sense to include both my old and new email addresses in the sign-off section, to both tie it to the old threads and make it easier to reach me if someone wants to contact me? (But I'm not sure of a "clean" way to do so, and it is probably low priority. Perhaps this current email is good enough?) - Matthew Ogilvie P.S.: Explanation and keywords to find this message (and me) with search tools: With regards to qemu, my primary interest (from that thread and related 2012 threads) is/was being able to run "Microport UNIX System V/386 v2.1" (ca. 1987) under qemu, which especially required: - Fixing various inaccuracies in qemu's model of the i8259 interrupt controller. - Implementing very old graphics card model(s) that Microport UNIX actually knows how to control properly. Perhaps original IBM monochrome display adaptor (MDA), CGA, and/or hercules graphics card. Or else my nasty qemu hackish patches I wrote that allowed VGA to work in text mode despite Microport driving it like CGA in a way that didn't work with real VGA hardware.
