Tickless kernel

[bmarkus]

Just reading a Red Har article about RHEL 6 kernel at

http://press.redhat.com/2010/05/05/red-hat-enterprise-linux-6-kernel-an-overview-and-genealogy/

Amongst others it says:

"Power management. Of several features that improve power management, perhaps the most important is called the “tickless” kernel. This reduces the traditional requirement for the hardware clock to interrupt the operating system (typically 1,000 times per second) in order to maintain accurate system and event timing. When processing requirements allow, the clock interrupt rate can be reduced dramatically, thereby allowing processors to enter low power states when idle."

What is about TC 3.0 kernel and tickless?

Meh, even TC 2.0 was tickless Enterprise is late as usual, the feature has been stable for two years or more.

Oh.... I have to go through the kernel options again before asking instead of using my (unrealible) memory

BTW, my up to date CentOS box next to me is running on 2.6.18

RHEL can be used for free for 90 days.
- What happens after that if you don't pay?
It turns to CentOS.

OT, but just remembered that quote
