osnews.com — Linux Kernel 2.6.21 has been announced. Linus writes: "So the big change during 2.6.21 is all the timer changes to support a tickless system (and even with ticks, more varied time sources). Thanks (when it no longer broke for lots of people ;) go to Thomas Gleixner and Ingo Molnar and a cadre of testers and coders."

@natenvousUm, windows does have a kernel. It has a miro-kernel to be specific. Maybe calling other people retarded isn't a good idea when you have no concept of OS theory (really it's rude all the time).Digg this down please, I posted in the wrong place.

There's this thing called Launchpad which solves all these upstream issues and... blah blah.The problem is the kernel doesn't use the normal bug tracking systems so probably Launchpad is opaque to it.

Wow, 500+ diggs and not even 1"I've had this in my custom kernel for 6 months" typical linux fanboy comment.Thank you.

Pity we didn't get away without a smartass preemptive Windows fanboy comment.

I've performed some "before and after" power measurements: <a class="user" href="http://digg.com/linux_unix/Linux_Kernel_2_6_21_s_Tickless_Kernel_Power_Measurements">http://digg.com/linux_unix/Linux_Kernel_2_6_21_s_Tickless_Kernel_Power_Measurements</a>

Any idea how this will affect VM clocks? Currently, VMs are really poor keeping their time. The only solution i have is a kludge: put "clock=pit" in the boot params. How will this affect it?

Dynticks in 2.6.21 doesn't include the power.saving features. It needs to set the CPU into a power saving mode; Current dynticks doesn't do it, it'll do in the future.
