Hi Beleswar, It's fine to enable drivers that are only used on a specific platform, but those should generally be loadable modules, not built-in. For the generic (platform-independent) options, I would suggest splitting them out into a separate patch, so you can describe better what the purpose is, since this is clearly not just for OMAP. > IKCONFIG*: > Allows reading the current kernel configuration through /proc/config.gz This one seems particularly unnecessary in a "defconfig" build since the configuration is already known based on the version. > THERMAL_EMULATION: > Adds emul_temp sysfs node under thermal zones to allow emulating > temperature changes. The documentation for this option suggests that we probably don't want it enabled. > FANOTIFY: > Allows sending open file descriptors to userspace listeners along with > file access events. > > USER_NS: > NAMESPACES: > Enable user NS to provide user info of different users for different > process. > > POSIX_MQUEUE: > Supports POSIX message queues for priority-based IPC. > > BSD_PROCESS_ACCT: > Enables BSD process accounting to allow user space program to write > process accounting information to a file. I assume these are all in order to run a particular userspace distro? Arnd
