ck kernel config question

I understand that the ck patches are aimed at decreasing latency without preempting the kernel. My question is: Should the "Preempt the Big Kernel Lock" be enabled with ck patches?

Accrding to Con Kolivas no they should not - see this ML thread for more info:

So one should use the "No Forced Preemption" Preemption model then too?

I guess that is a yes...

Hi,

As mentioned you do not need the pre-empt set. Additionally, it is worth reading up on the additional patches applied to the CK kernel. I've run the CK kernel for quite a while and have found it extremely performant for a desktop system. However, you should not use it for a server, that is not what it is designed for

So, no prempt in the kernel options at all? Not even the desktop one or the big kernel lock?
