Hi All,
I'm about to compile a new kernel and running oldconfig brings up this new set
of options. There is no help available, grep-ping through the Documentation
wasn't particularly revealing and I haven't found anything in Google to help
me decide what I need/want out of the three:
===================================================
* CPU/Task time and stats accounting
*
Cputime accounting
1. Simple tick based cputime accounting (TICK_CPU_ACCOUNTING)
> 2. Full dynticks CPU time accounting (VIRT_CPU_ACCOUNTING_GEN) (NEW)
3. Fine granularity task level IRQ time accounting (IRQ_TIME_ACCOUNTING)
choice[1-3]: ?
There is no help available for this option.
Prompt: Cputime accounting
Location:
-> General setup
-> CPU/Task time and stats accounting
Defined at init/Kconfig:297
Selected by: m
===================================================
Option 2 seems to have been selected by default, but I am not sure if this is
right for a laptop.
What have you chosen and why?

Each of the three options has it's own individual help.

Oops! Thanks for pointing this out and sorry for the noise ... I had only
tried "?" instead of "<option_number> ?"
Help is also visible and available when using menuconfig.
The 2nd option is best for my needs.
