Hi,
The 2.6.24.x kernel has Tickless (Power Management) feature for MIPS. Has anyone tried it for MIPS boards like Malta.
If anyone has tried it please let me know, if Tickless (CONFIG_NO_HZ) is working fine. How is the power saving was measured and do you have any figures in terms of savings it can give.
Appreciate your help on this..
Thanking You..

It works except for SMTC which does it's own rather complicated time
keeping thing and the mix of SMTC and dyntick turned out to be rather
fragile.
