Hi,
I would like to enable a kernel-desktop for ARM, especially for GFX images.
I modified kernel-default by using CONFIG_PREEMPT instead of CONFIG_PREEMPT_NONE. Couldn't we just make preempt_desktop the default for armv7?
It could save us a kernel flavour build but CONFIG_PREEMPT_NONE would be better for servers (better dry performances) and CONFIG_PREEMPT would be better for desktop interfaces (less latency).
Well, is the difference significant? If the loss in performance for server style workloads is negligible, why not always enable preemption? Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
