Kernel without RTC

[Shah, Nehal-bakulchandra]

Hi,

Currently we are having hardware which does not have RTC. It is single processor system. However it does have TSC timer.

Now, how to use scheduler with only TSC as current kernel scheduler leverage the RTC for scheduling? I had seen one old patch

http://marc.info/?l=linux-kernel&m=112013203625990&w=2 

But i guess this patch was later on not taken, It will be great if you can some pointers to move forward?


Thanks 
Nehal
