Hi Greg,
This is habanalabs pull request for the merge window of kernel 5.17.
It mainly enhances the driver to deal with extreme cases, such as
reset-during-reset, events during reset and allowing monitoring
applications to continue running during reset.
Full details are in the tag.
Thanks,
Oded

habanalabs: support hard-reset scheduling during soft-reset (2021-12-26 14:42:31 +0200)
----------------------------------------------------------------
This tag contains habanalabs driver changes for v5.17:
- Support reset-during-reset. In case the f/w notifies the driver
that the f/w is going to reset the device, the driver should
support that even if it is in the middle of doing another
reset
- Support events from f/w that arrive during device resets.
These events would be ignored which is bad as critical errors
would not be reported and treated by the driver.
- Don't kill processes that hold the control device open during
hard-reset of the device. The control device operations can't
crash if done during hard-reset. And usually, only monitoring
applications are using the control device, so killing them
defies their purpose.
- Fix handling of hwmon nodes when working with legacy f/w
- Change the compute context pointer to be boolean. This pointer
was abused by multiple code paths that wanted fast access to
the compute context structure.
- Add uapi to fetch historical errors. This is necessary as errors
sometimes result in hard-reset where the user application is
being terminated.
- Optimize GAUDI's MMU cache invalidation.
- Add support for loading the latest f/w.
- Add uapi to fetch HBM replacement and pending rows information.
- Multiple bug fixes to the reset code.
- Multiple bug fixes for Multi-CS ioctl code.
- Multiple bug fixes for wait-for-interrupt ioctl code.
- Many small bug fixes and cleanups.
