[PATCHES] sys/dev/videomode

[tlaronde%polynum.com@localhost]

Since the choice of the resolution (with 10.0 BETA) is not optimal, I
have started to review sys/dev/videomode in order to fix the
preferences.

The first step was to update the timings.

Since, with whatever choice for the resolution, a monitor will not do
what it is not able to do, I replaced the modelines, derived from
XFree86, with the specifications taken directly from the latest VESA DMT
specification (this is an update even compared to the current
xsrc/external/mit/xorg-server/dist/hw/xfree86/common/vesamodes).

One of the main difference is that I do not put the specification in the
XFree86 modeline format, but I take all the relevant informations from
the spec, from which the modelines can also---obviously---be derived
(the reverse is not true: a modeline doesn't distinguish between
back/front porch and borders; and the VESA identifiers are not
present even for VESA DMT modes).

I attach the "dmt" file for reference (the awk script is updated and
some modifications to other files are made in order to fit this in the
present code without modifying its behavior for now; so it is useless
alone).

To my surprise, some of the "Established timings" (there is a bitmap in
the EDID for these) are not specified in the VESA DMT.

So I added an "extradmt". I had to derive the pseudo DMT timings from
the XFree86 extramodes modelines, the problem being that, as said above,
the distinction between porch and border is not made. So some values are
fake ones.

A supplementary problem is that some of the Mac II modes are
not in the XFree86 modelines; but I found them in
linux/drivers/video/macmodes.c i.e. in a Linux source file, allowing
me to describe all the Established timing thus getting rid of the
disturbing DIAGNOSTIC "no data for est. mode %s\n".

The Linux source file is GPL 2.

The question is: when it comes to parameters/hardware specs (I'm not
taking code, I'm taking numbers), what is the license? Is it considered
as "public" information or is the license binding? Or is an acknowledge
of the source enough without being tied to the license of the file where
the information (not code) was found? Note: these go to an extradmt
file, i.e. is severed from the VESA DMT.
