Hi all,
I am trying to find detailed explanation of preemption option in config. For desktop, server, and low-latency desktop. Can anyone explain in what scenarios these are useful.
for server, quite likely you need preempt voluntary or none. The reason: you need to get the things get done fast, but user responsiveness (i.e GUI click response) could be sacrificed for desktop: between voluntary or full preempt. reason: you likely need fast response (i.e responding mouse click). Full preempt allow kernel to do context switch even if it's still in kernel mode, as long as preemption is allowed. if you're in doubt, pick voluntary... :) -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
