I am writing a new piece of driver to go on top of OHCI. I generate messages and send them by calling hpsb_write(). My questions are: 1. The hpsb_write() function exists but no-one in the existing stack calls it. Is there any reason for that? 2. Eventuallt hpsb_write() calls hpsb_send_packet() which hangs the kernel before the two calls to down(), even though the semaphore is initialized. This is my major concern now and I will be happy if you have an idea why this happens. 3. Are there any restrictions on using hpsb_write()? Are there prerequisits one has to fulfill before calling it? Thank you, Alex. |
