I would like to run the real time kernel from the suser-jengelh repository on my laptop, which an ATI Radeon graphics card. I have the kernel installed (along the original one) and it runs fine in INIT 3, but I can’t get graphics to work properly. How do I compile the fglrx driver for this kernel?
Why do you need to run an RT kernel? Do you expect to gain speed or something? RT is to guarantee that a specific task accomplishes its set within a guaranteed timeframe (a deadline). RT will not magically speed up your system and more than often will actually slow it down, especially when it comes to throughput. There’s a great article over at LWN which discusses some of the cons and pros of RT kernels and some of the misbelieves about speed on RT kernels
Since about a week, there is now an fglrx package plus KMPs in my repository. Feedback is welcome, because I could not really test it (no ATI hardware).
