Is there any workaround or alternative approach which will solve my problem?

Many thanks,

HI,

Is it possible to specify CONFIG_PREEMPT_RT=y in the Dom0 kernel? It seems that it is forbidden as it is not a menu option in make menuconfig and gets removed if I manually add it to the .config.

I want to run a sound server on Dom0 and am having problems with xruns at present, so need to be able to run a preemptive kernel.

Thanks,

Chris
