Many years ago i used a RT-os, But when seeing you asking for videodrivers and vmware......
For real RT-applications, you should want to avoid unneeded IRQ's at all time: barebone, no graphics (but serial console), no virtualisation, no add-on hardware and as much as possible unneeded io on your mobo disabled.
On linux kernels you can sort and prioritize IRQ's. They're called "Interrupt requests" for a reason.
If the realtime infrastructure is up and healthy then there's really no reason for your realtime applications to not deliver -- no matter what is going on on your desktop.
Well, the rt-application could suck, for that matter. Multiple rt-action might drain ressources. Hell, the metal could run hot :) And I don't know about hardware level virtualization and its effects on irq handling.

ps: What was the OS/application you were using?
Yes, well, i have to agree with the O.P. Some applications do need a graphical interface, But to use vmware on a rt-machine because the hardware is not supported by linux.... Well, i don't know. Probably it is not possible to seperate these functions into a seperate box.. For what i was using R.T.? The OS was (a cloned) mtos, and was used for frequency analysis (dtmf and dialtone recognition) for telefone exchanges, back in 85. hw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
