1) Make the driver "quiet" by sticking most boot messages behind bootverbose conditionals. This means that you won't see the sync and wide negotiation, but you will find out if they fail. 2) Add support to the 93cx6 serial eeprom code to read at an abitrary offset. This is needed so that we can access the second half of the eeprom on 3940 cards where the second channel's config is stored. 3) Add flags argument to ahcprobe(). This is used by the pci probe code to tell the generic driver that an adapter should be treated as a channel B device as well as notify it of the presence of external SCB SRAM. These are needed for some motherboard implementations of the aic7870 and for the 3940 controllers. 4) Print "Channel A"/"Channel B" instead of "Single Channel" for the two busses of the 3940. I received many reports of confusion about how the 3940 was probed since most people belived that only one ahc entry was needed. This will hopefully make it clearer. 5) Walk the SCBs to determine just how many their are if external SCB ram is detected. 6) Hard code that external SCB ram is present for the 3940 since it doesn't use the documented reporting facility for reporting the SRAM. :( 255 commands per channel are supported on the 3940. 7) Read the seeprom starting at addres 32 for the second channel of the 3940 so we get the right info for that channel. 8) Clean up printing of the "Disabling tagged queuing message". 9) Queue timeouts if they occur while we are handling a timeout. The code was totally unprotected in this scenario. Reviewed by: Timeout code reviewed by David Greenman <davidg> |
