Ok, just checking here. Those structs were a little suspicious. I'll
take your word for it so I think this can be used as a nice basis.
Just out of interest, are we sure that this is true. If for
instance I describe in code and comments exactly how some part of
the PCI specification works, are the PCI SIG going to be cross that
we've released internal information about how their "pay for" spec
works.
No clue here.
You're right, as I thought I said, there is no OGD specific code
here yet. This does nothing of any interest at all [*]. It's just
a line under the sand (to mix my metaphors). Don't bother to spend
too much time trying to understand it, it's just the start of a VGA
BIOS.
In that case I won't for now. I am curious though how much of this
code overlaps with the X driver that was developed a few ages ago for
the temporary HDL code, and how much of that is reusable. Have you
seen that code? You're obviously more experienced than me with this
kind of stuff so if you haven't, please do. :)
PS.
What's happened to project VGA?
<offtopic>
Worked my ass off last two months to have something demo-able for
college/uni/whatever you want to call it, and it's codebase is because
of that a little messy. I have to clean it up a somewhat before I toss
it online. Biggest issue with it is a) it has some off-by-one problems
(I'm guessing - but it looks like it) and b) it's ~12000 lines of new
code, so not entirely useable for anything else at the moment. The
demo works, sort of, over USB, but only half the time half the data
shows up on the screen, in a fixed resolution.

Also, the hardware turned out to be pretty buggy. The CPLD is /not/
working with the PCI bus and I couldn't be bothered to hack around it
until it did work, so I simply decided that I should cook up a second
revision of the card without the CPLD, but haven't gotten the time yet
to actually do that. What's also not helping is that I've got a few
connections here and there that are short-circuiting thanks to my
fantastic SMD skills. Makes debugging somewhat hellish.
So for the moment I just want to focus on the internship & entertain
myself with helping OGP, and I'll pick up pVGA once I've not touched
it for a month or two.
