This link shows that the in-kenrel documentation says that for a low- latency desktop preemption is recommented.
http://www.linuxtopia.org/online_books/linux_kernel/kernel_configuration/ch09s03.html <quote> Preemption Systems running as servers have very different workload requirements from those being used as a desktop for video and audio applications. The kernel allows different modes of "preemption" in order to handle these different workloads. Preemption is the ability of the kernel to interrupt itself while it is doing something else, in order to work on something with a higher priority, such as updating a sound or video program. To change to a different preemption model, use this menu: Processor type and features Preemption Model (X) No Forced Preemption (Server) ( ) Voluntary Kernel Preemption (Desktop) ( ) Preemptible Kernel (Low-Latency Desktop) If you wish to make the kernel even more responsive to higher priority tasks than the general preemption option provides, you can also allow interruptions to one of the main internal kernel locks: Processor type and features [*] Preempt The Big Kernel Lock This option is able to be selected only if you have already selected either the Preemptible Kernel or Symmetric multi-processing support options. </quote> -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1271742 Title: CONFIG_PREEMPT is not set.
