| | | * | | ath10k: fix copy engine 5 destination ring stuckRajkumar Manoharan2016-09-281-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Firmware is running watchdog timer for tracking copy engine ring index and write index. Whenever both indices are stuck at same location for given duration, watchdog will be trigger to assert target. While updating copy engine destination ring write index, driver ensures that write index will not be same as read index by finding delta between these two indices (CE_RING_DELTA). HTT target to host copy engine (CE5) is special case where ring buffers will be reused and delta check is not applied while updating write index. In rare scenario, whenever CE5 ring is full, both indices will be referring same location and this is causing CE ring stuck issue as explained above. This issue is originally reported on IPQ4019 during long hour stress testing and during veriwave max clients testsuites. The same issue is also observed in other chips as well. Fix this by ensuring that write index is one less than read index which means that full ring is available for receiving data.

It mostly happens on A-MPDU stalls (e.g. when station goes out of range). It may take up to 5-10 secods for the firmware to recover and for that time it doesn't process packets. It's still useful to have a message on time out as it may indicate some firmware problem and incorrect key update. Raising a WARNING however wasn't really that necessary, it doesn't point to any driver bug anymore and backtrace wasn't much useful.

Move the fall-through code into else branches to avoid variable shadowing. While doing so, rename some of the variables and do some other cleanups (like removing void * casts of void * pointers.)

As this quantity is usually zero, this output is not needed. In fact, there will be a report if the status is not zero, thus the debug line in question could probably be deleted. Rather than taking that action, I have changed it to only be printed when the newly added RTL8XXXU_DEBUG_INTERRUPT bit is set in the debug mask.
