Hi, all sorry to post here, i don't know other maillist for discussing deeply in linux. two questions here. firstly, How to check the values of kernel configurations. when we compile a kernel, we must set the values. and now, when the system is running, i want to know them again. how? maybe a command is ok or a file can be read. secondly, from somewhere, i know the device polling is been enabled in kernel of version 2.6, and a api named NAPI is supported for using this feature. is it true? maybe it is nothing at all or something else. i don't know but want to learn. would you like to give me some directions.
