Dear sir,

I want to build the L27.IS.2.P2 release for a GP device. Its release notes says it is recommended not to build the SMC kernel driver. Do you know what's the SMC kernel driver for? How to build with or without this driver?

Thanks!

Connie

    Connie,

    The SMC kernel driver is the component "CONFIG_SECURITY_MIDDLEWARE_COMPONENT", which you can disable through the kernel config.  (By default, it is enabled.)  It is needed only for the HS (high security) OMAP devices, not GP (general purpose), and removing this component will save some space in the kernel binary.  However, your GP system should still boot and run fine whether or not you disable CONFIG_SECURITY_MIDDLEWARE_COMPONENT.  I just tested it both ways.

    Regards,

    Gina
