[Impact]
Some improvement are made to qat which makes it
more resilient and able to handle reset in a
better way.
There is an upstream patch set that improve this
but it's applied to linux-next and scheduled for 6.9.
We should apply the patch set to the Noble 6.8 kernel,
so we experience less issue with qat and be more maintainable.
[Test case]
Use the added mechanism to inject errors and rmmod/modprobe the module
to verify that qat recover and log issues properly.
[Fix]
Apply the following commits (from linux-next):
2ecd43413d76 Documentation: qat: fix auto_reset section
7d42e097607c crypto: qat - resolve race condition during AER recovery
c2304e1a0b80 crypto: qat - change SLAs cleanup flow at shutdown
9567d3dc7609 crypto: qat - improve aer error reset handling
750fa7c20e60 crypto: qat - limit heartbeat notifications
f5419a4239af crypto: qat - add auto reset on error
2aaa1995a94a crypto: qat - add fatal error notification
4469f9b23468 crypto: qat - re-enable sriov after pf reset
ec26f8e6c784 crypto: qat - update PFVF protocol for recovery
758a0087db98 crypto: qat - disable arbitration before reset
ae508d7afb75 crypto: qat - add fatal error notify method
e2b67859ab6e crypto: qat - add heartbeat error simulator
[Regression potential]
We may experience qat regression when crashing or restarting the module. |

e2b67859ab6e crypto: qat - add heartbeat error simulator
[Regression potential]
We may experience qat regression when crashing or restarting the module. |
[Impact]
This set improves the error recovery flows in the QAT drivers and
adds a mechanism to test it through an heartbeat simulator.
This is an upstream patch set applied to linux-next and scheduled for 6.9.
Link to the upstream submission:
https://patchwork.kernel.org/project/linux-crypto/cover/20240202105324.50391-1-mun.chun.yep@intel.com/
We should apply this set to the Noble 6.8 kernel,
in order to experience less issues with qat and improve maintainability.
An added commit is required to update the configuration.
[Test case]
Unload and reload the module to verify that qat recover
and log issues properly. Use the added error injection mechanism
to verify the recovery flow.
