-Subject: ath10k: fix copy engine 5 destination ring stuck
-
-From: Rajkumar Manoharan <rmanohar@qti.qualcomm.com>
-
-commit 0628467f97b5227755428bac10a68257322f7e34 upstream.
-
-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.
