Subject: [git pull] habanalabs pull request for kernel 5.17
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.
