| H A D | isp_library.c | diff 292739 Sat Dec 26 02:42:17 MST 2015 mav Make virtual ports control asynchronous. Before this change virtual ports control IOCBs were executed synchronously via Execute IOCB mailbox command. It required exclusive use of scratch space of driver and mailbox registers of the hardware. Because of that shared resources use this code could not really sleep, having to spin for completion, blocking any other operation. This change introduces new asynchronous design, sending the IOCBs directly on request queue and gracefully waiting for their return on response queue. Returned IOCBs are identified with unified handle space from r292725. |
