- Add support for memory mapped I/O. - Use DMA to get SCBs down to the adapters. - Remove old paging code. - Be much smarter about how we allocate SCB space. The old, simple method wasted almost half a page per SCB. Ooops. - Make command complete interrupt processing more efficient. - Break the monolithic ahc_intr into sub-routines. The sub-routines handle rare, special case events so the function call is not a penalty and the removal of the code from the main routine most likely improves performance instruction prefech will work better and less code is pushed into the cache. - Never, ever allow tagged queueing if a device has disconnection disabled. - Clean up and simplify timeout code. Many of the changes are to handle the new DMA scheme. |
