| |
This series introduces several improvements to the function that performs AP queue resets:
* Breaks up reset processing into multiple smaller, more concise functions.
* Use TAPQ to verify completion of a reset in progress rather than mulitple invocations of ZAPQ.
* Check TAPQ response codes when verifying successful completion of ZAPQ.
* Fix erroneous handling of some error response codes.
* Increase the maximum amount of time to wait for successful completion of ZAPQ.
Change log v1 => v2: ------------------- Remove patch 7/7 to restore original behavior since we don't know whether interrupts are disabled when an unexpected response code is returned from ZAPQ. (Halil)
