Subject: [git pull] habanalabs pull request for kernel 6.2

Hi Greg,

This is habanalabs pull request for the merge window of kernel 6.2.

There isn't any fancy stuff to talk about. There are some minor features and
enhancements, but most of the commits are multiple bug fixes, refactors, etc.

Full details are in the tag.

Thanks,
Oded

  habanalabs: fix VA range calculation (2022-11-23 16:54:10 +0200)

----------------------------------------------------------------
This tag contains habanalabs driver changes for v6.2:

- New feature of graceful hard-reset. Instead of immediately killing the
  user-process when a command submission times out, we wait a bit and give
  the user-process notification and let it try to close things gracefully,
  with the ability to retrieve debug information.

- Enhance the EventFD mechanism. Add new events such as access to illegal
  address (RAZWI), page fault, device unavailable. In addition, change the
  event workqueue to be handled in a single-threaded workqueue.

- Allow the control device to work during reset of the ASIC, to enable
  monitoring applications to continue getting the data.

- Add handling for Gaudi2 with PCI revision 2.

- Reduce severity of prints due to power/thermal events.

- Change how we use the h/w to perform memory scrubbing in Gaudi2.

- Multiple bug fixes, refactors and renames.
