Hi All,
I've been trying to develop a gui to interact with some rtlinux modules.
The problem is, when a real time (high priority) task is running in kernel
space, svgalib degrades in performance: lower update rates and a lag in
mouse/keyboard handling. Also, I run my little gui, telnet into the
machine, and run "top". I see that the one svgalib program takes up
99% of the cpu. When X is running, it takes up 0.5 % of the cpu. Why is
this so?
Does anyone know how to keep svgalib robust when the system is under heavy
usage? Such as a way to lower the cpu usage of svgalib or change it's
priority.
Thanks.
-David
