[Oded Gabbay]

Hi Dave, Sima.

Habanalabs pull request for 6.9.

No uapi changes this time. Just minor features, improvements, code cleanups
and bug fixes. Also one small change in accel subsystem file.

Full details are in the signed tag.

Thanks,
Oded

  accel: constify the struct device_type usage (2024-02-26 09:59:18 +0200)

----------------------------------------------------------------
This tag contains habanalabs driver and accel changes for v6.9.

The notable changes are:

- New features and improvements:
  - Configure interrupt affinity according to NUMA nodes for the MSI-X interrupts that are
    assigned to the userspace application which acquires the device.
  - Move the HBM MMU page tables to reside inside the HBM to minimize latency when doing
    page-walks.
  - Improve the device reset mechanism when consecutive heartbeat failures occur (firmware
    fails to ack on heartbeat message).
  - Check also extended errors in the PCIe addr_dec interrupt information.
  - Rate limit the error messages that can be printed to dmesg log by userspace actions.

- Firmware related fixes:
  - Handle requests from firmware to reserve device memory

- Bug fixes and code cleanups:
  - constify the struct device_type usage in accel (accel_sysfs_device_minor).
  - Fix the PCI health check by reading uncached register.
  - Fix reporting of drain events.
  - Fix debugfs files permissions.
  - Fix calculation of DRAM BAR base address.
