[git pull] habanalabs for drm-next-6.8

[Oded Gabbay]

Hi Dave, Daniel.

Habanalabs pull request for 6.8.

It's rather small this time, as Gaudi2 is very stable at this point.

Same as in the previous cycle, it's a bit all over the place.
A few uapi changes, mostly improvements and bug fixes.

Full details are in the signed tag.

Thanks,
Oded

  accel/habanalabs: fix information leak in sec_attest_info() (2023-12-19 11:09:44 +0200)

----------------------------------------------------------------
This tag contains habanalabs driver changes for v6.8.

The notable changes are:

- uAPI changes:
  - Add sysfs entry to allow users to identify a device minor id with its
    debugfs path
  - Add sysfs entry to expose the device's module id as given to us from
    the f/w
  - Add signed device information retrieval through the INFO ioctl

- New features and improvements:
  - Update documentation of debugfs paths
  - Add support for Gaudi2C device (new PCI revision number)
  - Add pcie reset prepare/done hooks

- Firmware related fixes and changes:
  - Print three instances version numbers of Infineon second stage
  - Assume hard-reset is done by f/w upon PCIe AXI drain

- Bug fixes and code cleanups:
  - Fix information leak in sec_attest_info()
  - Avoid overriding existing undefined opcode data in Gaudi2
  - Multiple Queue Manager (QMAN) fixes for Gaudi2
  - Set hard reset flag if graceful reset is skipped
  - Remove 'get temperature' debug print
  - Fix the new Event Queue heartbeat mechanism
