Hi Shaun... > possible to change the kernel hz live show how with out having to > recompile? ztdummy needs the hz value set to 1000 AFAIK, you can't. Even if you use something like dynamic tick patch once included in -ck patchset, the timer tick itself can't be set from user space. I also check kernel boot parameter and I failed to find such a parameter. regards Mulyadi -- Kernelnewbies: Help each other learn about the Linux kernel.
