Subject: [PATCH 0/7] improve AP queue reset processing
Date: Tue, 13 Dec 2022 10:44:30 -0500 [thread overview]
Message-ID: <20221213154437.15480-1-akrowiak@linux.ibm.com> (raw)
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.
* Always clean up IRQ resources when the ZAPQ response code indicates an
error.
* Consider reset complete when ZAPQ response code indicates the adapter to
which a queue is connected is deconfigured. All queues associated with an
adapter are reset when it is deconfigured.

s390/vfio_ap: verify ZAPQ completion after return of response code
zero
s390/vfio_ap: fix handling of error response codes
s390/vfio_ap: increase max wait time for reset verification
