Hi All, I need to implement "select" system call for a character device. The character device i am talking to doesnt not raise any interrupt when there is data. It just writes the data on the HPI bus. Now for me to provide support for select, the poll_wait function should be waiting on a wait_queue and should be awakened by the Rx interrupt process. Is there a way to implement this other than creating a separate polling task(kernel_thread) for receive, which continuously polls the device and awakes the wait queue when there is data?
