Hi Duy,

The kernel options which are described in the "README" file are the 
kernel configurations we need to enable (before building the kernel) for 
testing that particular feature like controllers, power management or 
hotplugging. The facility of kernel config analysis and building the LTP 
based on that config options is not yet available. So you need to 
determine which tests you wish to run per your kernel configuration and 
than execute a customized LTP test run.

Thanks,
Shubham
