Hello,
I want to ask if there's any sort of minimalistic mesa implementation
out there ? I'm currently stuck on a sis chipset laptop that has no dri
support (the doomed 760 chipset). Therefor i can't have hardware
acceleration and opengl is awfully slow. I've looked at some suggestions
how to speed things up, but if i run someone else's compiled code that
has lots of features turned on i have no chance to apply some of the
most important ones.
Is there some kind of crippled mesa fork out there that does very basic
opengl rendering in software ? Or is there any kind of preload library
that overloads the hardcore visuality effect calls that transparently
disables the deeper wonders of opengl like dual lights etc. ?
We don't have anything like that.
I'm willing to give back a lot of beauty just to get some things
running over here :)
I've seen TiniGL that was programmed by a french programmer, but it's
implementation is rather incomplete and doesn't even pass the very basic
gl/glx calls. It can run glxgears but with weird results.
If there are no implementations out there yet, do you have any
suggestions ? I guess both, a lightweight mesa and a preloading
"autodisabler" are quite possible but am not sure which one should be
selected for implementation.
Some autodisablements and cutbacks should be enough to run things, i
see the opengl running much faster under windows with sis's native drivers.
If you want to forcibly disable certain rendering features (like
texturing or blending) you could go into src/mesa/main/enable.c and
no-op the code that turns those features on.
