Hm, I have made some changed in VGA Drivers to test. I found that using Java
to Fill Memory
IS VERY SLOW. I have added a operation using C/ASM to fill memory with a
value. Is that
good to have such a operation ? Also, when I want to fill whole screen with
the same color using Java.
It will hangs after a period of time. I guessed it would be a stack
overflow. Any Idea about it ?
Also, will Graphics Drivers are under JJOS Modules ?
