And yes an app might ask a video controller to do something.
That violate my understanding of how an OS is supposed to keep an app from directly accessing hardware. One of the big problems, back in the DOS days, was how apps would bypass the OS and talk directly to the hardware. However, it was pretty much necessary to do that in light of the poor support in DOS
I won't get into a pizzing match over how a virtual system should or should no map clients onto hardware, for example letting a virtual DOS/Windows access the hardware. But do look at how X-Windows/xorg has its various hardware specific modules access the hardware. Also look at how 3rd party drivers do it. One way is via shared memory .... Also look at DRI (Direct Rendering Infrastructure) which is a framework for allowing software to access graphics hardware in a safe and efficient manner. -- The heresies we should fear are those which can be confused with orthodoxy. -- Borges, "The Theologians" -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
