Dear Jan Hudec. Thanks for the information, well i have following difficulties. 1. How to handle/write the Bottom Half part of Interrupt for Device Drivers 2. If any error, then the messages during the running of Device Driver modules where(in which file) they are written by Kernel, or we have to specify the location/Pathname of file during the implimentation. Thanks in advance.

Buffers are rather transient stuff during IO operations. Kernel will allocate memory for them as they are needed. All memory, that is not used by kernel or applications is used for caching files (page cache). No need to configure that either. ------------------------------------------------------------------------------- Jan 'Bulb' Hudec <bulb@ucw.cz> -- Kernelnewbies: Help each other learn about the Linux kernel.
