/* |
* ScanLogic SL811HS/T USB Host Controller |
* The hard interrupt is the main entry point. Start, callbacks, and repeat |
|
* are the only others called frequently. |
|
* |
|
* Since this driver attaches to pcmcia, card removal at any point should be |
|
* expected and not cause panics or infinite loops. |
|
* |
|
* This driver does fine grained locking for its own data structures, however |
|
* the general USB code does not yet have locks, some of which would need to |
|
* be used in this driver. This is mostly for debug use on single processor |
|
* systems. Actual MP use of this driver would be unreliable on ports where |
|
* splipi is above splhigh unless splipi can be safely blocked when |
|
* calculating remaining bus time prior to transfers. |
|
* |
|
* The theory of the wait lock is that start is the only function that would |
|
* be frequently called from arbitrary processors, so it should not need to |
|
* wait for the rest to be completed. However, once entering the lock as much |
|
* device access as possible is done, so any other CPU that tries to service |
|
* an interrupt would be blocked. Ideally, the hard and soft interrupt could |
|
* be assigned to the same CPU and start would normally just put work on the |
|
* wait queue and generate a soft interrupt. |
|
* |
|
* Any use of the main lock must check the wait lock before returning. The |
|
* aquisition order is main lock then wait lock, but the wait lock must be |
|
* released last when clearing the wait queue. |

|
* |
|
* Disabling a power check and attaching aue to a keyboard and hub |
|
* that is directly attached (to CFU1U, 100mA max, aue 160mA, keyboard |
|
* 98mA) sometimes works and sometimes fails to configure. After |
|
* removing the aue and attaching a self-powered umass dvd reader |
|
* (unknown if it draws power from the host also) soon a single Error |
|
* status occurs then only timeouts. The controller soon halts freeing |
|
* memory due to being ONQU instead of BUSY. This may be the same |
|
* basic sequence that caused the no status/bad length errors. The |
|
* umass device seems to work (better at least) with the keyboard hub |
|
* when not first attaching aue (tested once reading an approximately |
|
* 200MB file). |
|
* |
|
* Overflow can indicate that the device and host disagree about how |
|
* much data has been transfered. This may indicate a problem at any |
|
* point during the transfer, not just when the error occurs. It may |
|
* indicate data corruption. A warning message is printed. |
|
* |
|
* Trying to use both A and B transfers at the same time results in |
|
* incorrect transfer completion ISR reports and the status will then |
|
* include SL11_EPSTAT_SETUP, which is apparently set while the |
|
* transfer is in progress. I also noticed data corruption, even |
|
* after waiting for the transfer to complete. The driver now avoids |
|
* trying to start both at the same time. |
|
* |
|
* I had accidently initialized the B registers before they were valid |
|
* in some driver versions. Since every other performance enhancing |
|
* feature has been confirmed buggy in the errata doc, I have not |
|
* tried both transfers at once again with the documented |
|
* initialization order. |
|
* |
|
* However, I have seen this problem again ("done but not started" |
|
* errors), which in some cases cases the SETUP status bit to remain |
|
* set on future transfers. In other cases, the SETUP bit is not set |
|
* and no data corruption occurs. This occured while using both umass |
|
* and aue on a powered hub (maybe triggered by some local activity |
|
* also) and needs several reads of the 200MB file to trigger. The |
|
* driver now halts if SETUP is detected. |
