| |
Hi all,
I am writing a kernel thread for serial port communication. If the serial character device file is opened by a filp_open() or manipulating using a struct file in the kernel, how can I know whether the previous written buffer has commit or not? Similarly, how do I know is there any data ready for read for non blocking access? Thanks.
regards, David Chow
