>"When you say boards with OGL ES graphics chips come with the drivers
in them, do you mean the OGL ES driver is inside the graphics chip?"
inside box.. on CD or floppy :-)
____________________________
you got right to the point there actually, drivers do belong in hardware, if you
ask me... i just fail to see why not
we already do have pixel/vertex shaders, which is, roughly speaking, a way to
put software(drivers) into hardware..
but what scitech already did do, is that they "isolated" all platform
and OS specifics out of the drivers (device code)
so, we have: one device <-> one driver (+ os/platform specifics)
AMD if wanted could put those Scitech binaries *inside* the chip and you would
just get your +os/platform specific code on CD or floppy...
the same thing is with OpenGL ES drivers, as long as something is "standard
enough" drivers can be made easily to support multiple OS and architectures
(separate device code from os/cpu code)
the best thing with OpenGL ES is that - it came to be as no other standard
before, in computer video industry
as you know well, in windows and in linux nothing works without drivers... and
if you look around the internet all the problems people EVER have is because of
the drivers...
> Help, my ______ is not working? my OS is _____
where in most cases soulution is just to go somewhere and download and install
correct driver ...unless, of course, it is hardware fault or virus
and these OpenGL ES drivers are just like SciTech *os/platform independent*, and
as long as they are like that its fine - no real need to be inside the
hardware... i do believe, however, they will soon start doing this... and as a
matter of fact you might be right after all - its not impossible that OpenGL ES
chip comes with some 'driver' inside
http://www.compulab.co.il/x270/html/x270-cm-datasheet.htm
But apparently $350 for one board.

...........
it looks to me that modifying bumstix to use OpenGL ES might be a matter of only
purchasing OPTIONAL 2700G chip that somehow can be connected to that "LCD
controller", that would be great
howover, the only board that does offer that option right now seem to be one you
found:
CX-X270
http://www.compulab.co.il/x270/html/x270-cm-datasheet.htm
i can not find any similar boards with nvidia/fujitsu/ati(amd) graphic chips,
but i think soon there will be some, and all OpenGL ES boards are compatible
within one OS, no matter if its x86 or ARM or other
OpenGL ES seem to be very well supported by manufacturers - that means that
bumstix, even as an ARM architecture is not a problem anymore.. at all!
everythig is there - SDKs, development kits, 3D modeling software, 3d
visualisation engines.. everything!
so, i was wrong... there IS lots of people that DO compile for ARM and
apperantly it all works rather smoothly!
ah, buy the way... since ARM is popular platform it might be quite possible to
have OpenGL *without* 2700G chip, i was only worried that we might not be able
to compile stuff for ARM easily and i thought no one would ever bother to port
mesa there... / "CRT controller" does seem to be doing the job of
being "video chip", where it would be preferable to have one with as
much framebuffer as possible (framebuffer = "VRAM" - video memory),
only the memory that "LCD controllers" can utilize seem to be only
'normal' RAM (SDRAM)
in New Zealand, no one seem to have ever even heard of anything like bumstix,
the closes thing i can buy is DELL pda, full device with PXA270, but its $800
and doesnt have 2700G
so i oredered one of these from australia, i hope ill have it in a week
CX-X270 http://www.compulab.co.il/x270/html/x270-cm-datasheet.htm
one of my goals now is to make Linux based OS that will work just the same if
you boot it on PC, laptop, mobile phone or anywhere else where OpenGL can run -
with universal embedded/desktop *3D windowing sytem* built with OpenGL, visualy
similar to - Compiz/Beryl/Vista/MacosX
the other thing id like to be able to do is - to make a board even SMALLER than
bumstix
only to have CPU-RAM + GPU-VRAM pairs on it !
and get rid of all serial/parallel, ac97, wi-fi, advanced PCMCIA, I/O, COM..
well anything but CPU+GPU and memory they need.. / i would instead put only few
BUT much more Plug'n'Play' oriented connectors - like USBs for
keyboard/mouse and also couple TV-out CRT/LCD connectors like on graphic card,
so it would be easily pluggable just like any other PC.. its possible to connect
pretty much any device to usb and it wouldnt require any additional
accessories(there might be even more suitable connector for multy-purpose like
that)
i guess those pin based connectors that they use on bumstix are prefferable if
you want to integrate parts tightly together and minimize the use of cables, but
(all) connectores could be made two-sided, so that you could do both - connect
externaly with cable and/or internaly with some pin/slot connector
it looks like such *CPU+GPU only* combo could fit on 1/3 of bumstix
i'll try to conntact AMD to see if that can be ordered (it looks like thats
exactly what they offer, when they say - design your own board!), cost of that
stripped board might be even less that $70, especially if oredered directly from
AMD
they dont mention if thats open for individuals/hobbists or only for companies
that order large volumes..
i also sent e-mail to bomstix sales@ - to ask if they provide optional 2700G
chip and if there are any price drops on volume orders, since there is nothing
even close to that here in NZ, it seems i could make business just by importing
bumstix and selling customized embedded solution kits or something like that, i
guess i could also make my own Linux based mobile phone or PDA or Linux
"GameBoy" or whatever : - )
cheers,
p.s. did you get myOS running?

there is lot to read, but what i see, they let you modify and customize
products, so maybe you can order directly from them your custom-made
"gumstix"... / their stuff is mainly x86 which is good..

if not that,
than you MUST have *something* with that Intel 2700G, thats great chip!!
its based on GPU they used in SEGA Dreamcast !!!! its OpenGL ES and is fully
accelerated !!
**** The 3D accelerator is capable of processing about 831 000 triangles per
second.****
that probably is not quite true, but if it is thats around what average game on
playtation1 would need, im very surprised, that is FASTER THAN MOST OF DESKTOP
LINUX platforms, not because the chip is better than dektop nvidia/ati cards but
because drivers for Linux are terrible... this is GREAT, hope its not too
expensive
i dont know about you,
but im going shopping 1st thing tomorrow morning.. hopefully they sell that
stuff here..
i guess, i can always buy full device, like whole phone if theres one with 2700G
chip

gumstix does seem to be only the only one to make anything of that size, i
wonder how long before they do put some of above processors on gumstix

A little more info, not sure you saw this: http://docwiki.gumstix.org/Display
sheesh, if thats the best info we are in trouble...
however, now we know there are controllers with and without framebuffer, where
ones with fb could be much what graphic chip is.. thats good
if gumstic can confirm that it can run X11 on VESA drivers thats *green light*
if they tried to compile mesa or get OpenGL running they could tell us that too
unfortunately for ARM everything is in mesa/Xorg hands to get OpenGL run
however, for other platforms you have choice of these:
SciTech's products include, SciTech SNAP Graphics,
a fully accelerated binary compatible graphic device
driver solution for Enterprise, Thin Client and Embedded systems, and
SciTech MGL, a professional graphics library used to speed development
of today's multi-OS software programs. SciTech products support Linux
(with or without X11), Qt/Embedded, Windows NT, Windows 9x, Windows CE,
OS/2, On-Time RTOS 32, and DOS operating systems and now support x86,
x86-64, Power PC, and MIPS (32 and 64bit) processors.
