[Mesa3d-dev] Mesa - Scitech? myOS - Miniature, Linux based OpenGL development system without X

2007-03-31 Thread ZeAtShuttle
hi,


brian suggested this was the best place to post this info and my questions, so 
here i go:


*** project

myOS - Miniature, Linux based OpenGL development system without X
It is bare bones Linux system, stripped down of everything, but core necessary 
files to compile and run OpenGL/C code. It has simplified directory structure 
and cleaned up internal cross referencing.

There is complete OpenGL Red Book together with 45 examples converted to use 
Scitech's drivers. Examples are organized to follow chapters and are ready to 
compile and run, they look very much like their GLUT version in Red Book. This 
little collection is really all one needs to learn OpenGL. In fact the whole 
system being very bare bones and really simple can be used as learning tool to 
teach Linux basics and C/OpenGL programming...

http://one.xthost.info/zelko/opengl.html

there are more OpenGL related downloads on that page
including old demos that were developed for Voodoo2 using Mesa





*** questions

1.)
can you please tell me,
since Scitech drivers are based on Mesa, why there is no mention of them on 
Mesa web site?



2.)
can you help me figure out,
how come no one uses Scitech to do Linux without X even tho they are clean, 
working solution?
and, i mean there is not a single Linux project using them, until now..



3.)
i could not figure out 'Mesa minixgl', dont even know what exactly and where is 
the source code for it, i tried GGI, directFB and looked into other without X 
projects, but they so much trouble to compile, have dependencies that i want to 
get rid of, hard to isolate, clean or are simply too big. since all the 'Linux 
without X' drivers are based on Mesa anyway, i assume minixgl might be most 
simplistic and smallest, therefore best solution for me, so:

is minixgl active? 
can someone point out if there is nice simple link that will download all 
necessary source of minixgl in ONE file?



4.)
im looking forward to Mesa fbdev/DRI project or similar to have wider supported 
hardware, but meanwhile can you suggest if you know of any other Linux drivers 
that might be used to create Linux-OpenGL without X system?



cheers,
zelko

Mesa is BSD licensed, anyone can and does take it and use it, the project 
may never find out or have any contact with the ppl using it...

closed source? no idea what level the drivers are at..

Miniglx isn't active in the sense of ppl do development on it to further 
it, I have deployed it in a number of OpenGL without X platforms, and I 
generally take the Mesa tree, make it work for what I want, and if the 
changes are applicable to upstream I push them back into the mesa tree, at 
this stage I'm probably the miniglx de-facto maintainer... miniglx ships 
as part of Mesa (but not in the tarballs..) you'll have to use git to grab 
the latest Mesa development tree then make linux-solo-x86 in theory 
should build a miniglx system, that along with a couple of hacks the drm 
to bypass the master authorisations should allow it to run on radeon or 
intel (granted I don't use radeon with it anymore so it may have 
bitrotted..)

Miniglx currently in theory works hw-accelerated on radeon and intel i9xx 
hardware using the Linux kernel fb-drivers to do modesetting, and the drm 
to do the 3D acceleration, when the intel modesetting code is in the drm 
tree I'll make a miniglx to use that as opposed to fbdev just for a proof 
of concept and for perhaps an upcoming deployment into a production 
system..

Dave.
