[git pull] habanalabs for drm-next-6.5

[Oded Gabbay]

Hi Dave, Daniel.

Habanalabs pull request for 6.5.

As Gaudi2 is pretty much stable, this contains mostly bug fixes and small
optimizations and improvements.

Full details are in the signed tag.

Thanks,
Oded

  accel/habanalabs: refactor error info reset (2023-06-08 12:35:56 +0300)

----------------------------------------------------------------
This tag contains additional habanalabs driver changes for v6.5:

- uAPI changes:
  - Return 0 when user queries if there was a h/w or f/w error and no such error happened.
    Previously we returned an error in such case.

- New features and improvements:
  - Add pci health check when we lose connection with the firmware. This can be used to
    distinguish between pci link down and firmware getting stuck.
  - Add more info to the error print when TPC interrupt occur.
  - Reduce amount of code under mutex in the command submission of signal event.

- Firmware related fixes:
  - Fixes to the handshake protocol during f/w initialization.
  - Display information that the f/w sends us when encountering a DMA error.
  - Do soft-reset using a message sent to firmware instead of writing to MMIO.
  - Prepare generic code to extract f/w version numbers.

- Bug fixes and code cleanups. Notable fixes are:
  - Unsecure certain TPC registers that the user should access.
  - Fix handling of QMAN errors
  - Fix memory leak when recording errors (to later pass them to the user)
  - Multiple fixes to razwi interrupt handling code
