- 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. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEE7TEboABC71LctBLFZR1NuKta54AFAmHJcoMACgkQZR1NuKta 54BXBwf+NYkQ8w3TUR2JSkPs3/pk3XFL+OAXq9NBn2bGJ0qoj8VUz6VkcphJ3vAq 3PyLLxeVs8dk+cVePKEnBj1krED5fFBaxIQbp+g1VjS2LsMiHm2Nwi0iDkLWqo1i 7jwFgATzmnsRvEPhhwke7/Gd+rZ9eCfJ2NuE5Hbb2+JkzIaOCo6ZUZns9diSVDsq X9zaIQSnYxMd4XEhE8CP4BChJO87i+Ik56ZbqrtKhpLz3kkV+Re5S6dnsEluyGuZ FXmUXyu5I8NbsGmmHZ9aWrCm/DmhKsF8/UWhKD5i/ECvpQ+U4nO2ii9XiCeuaDwQ yhsYe1LbqMlroJVkIqTnbBbrSSP6bA== =anio -----END PGP SIGNATURE----- Merge tag 'misc-habanalabs-next-2021-12-27' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into char-misc-next Oded writes: This tag contains habanalabs driver changes for v5.17: - Support reset-during-reset.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
