Hi I have few basic questions about programming intel 945GM/965 chipsets.
Offcourse 945GM doesnt have GPU but as i noticed by reading its linux drier
source can be programed aswell.
My first question is where in CPU memory area is window for displayed graphics
( there are few registers MMADR=e8400000h(19-31), GMADR=d0000000(28-31) chich
can control it, but my experimenting with them and memory pointed by them didnt
bring any resoults) like for example for VGA A0000-BFFFF where i can control
number of window by suitable registers. Maybe is there some book ro program
graphics on intel ?
Secund question is about GPU "direct" programming. Supouse that i have
assembler program writen in opcodes somewhere in host(CPU) memory ( shape of
this program is topic on another question )how to to start this program on some
EU in GPU ( copy to graphics memory, and set some register, lets call it
EIP/RIP on GPU, to start this program ). If there is some simple example of
such working programm ?
Third one, is there possibility to make some general purpouse commputing on
945GM, there is not much about it in intel manuals ( on linux intel graphics
not much either), and if its true how to do it ( again how to force chip to
make claculations etc. )
I will be welcome to any advices, books etc.
Luke
