No, uname did not show anything. Is there any way to get the kernel preemption mode, programatically?
Thanks, --Sri

Hi,
Am using kernel 2.6.18-195(centos 5.5). My kernel configs have CONFIG_PREEMPT_NONE=7 and "CONFIG_PREEMPT_VOLUNTERY is not set". How to check that preemption is really in place? Is there any way to check my kernel is configured with what preemption levels?
Hmm, uname -a?
I'm sure its in /sys somewhere.
Remember /sys is part of the official ABI. Also, you see what your config look like for sure by looking at /proc/config.gz (that file is virtual, but shows the contents of how your config file was at compile time for the running kernel. Greg
