** Description changed:
[Impact]
- Some improvement are made to qat which makes it
- more resilient and able to handle reset in a
- better way.
+ This set improves the error recovery flows in the QAT drivers and
+ adds a mechanism to test it through an heartbeat simulator.
- There is an upstream patch set that improve this
- but it's applied to linux-next and scheduled for 6.9.
+ This is an upstream patch set 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 issues with qat and be more maintainable.
+ Link to the upstream submission:
+
https://patchwork.kernel.org/project/linux-crypto/cover/20240202105324.50391-1-mun.chun@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]
- Use the added mechanism to inject errors and rmmod/modprobe the module
- to verify that qat recover and log issues properly.
+ 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.
