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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
