Merge tag 'misc-habanalabs-next-2022-09-21' 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 v6.1:
- Support new notifier event for device state change through eventfd.
- Add uAPI to retrieve device attestation information for Gaudi2.
- Add uAPI to retrieve the h/w status of all h/w blocks.
- Add uAPI to control the running mode of the engine cores in Gaudi2.
- Expose whether the device runs with secured firmware through the INFO ioctl
and sysfs.
- Support trace events in DMA allocations and MMU map/unmap operations.
- Notify firmware when the device was acquired by a user process and when it
was released. This is done as part of the RAS that the f/w performs.
- Multiple bug fixes, refactors and renames.
- Cleanup of error messages, moving some to debug level.
- Enhance log prints in case of h/w error events for Gaudi2."
