- Drop L3 bank mask reporting from the media GT on Xe3 and later. Only
do that for the primary GT. No userspace needs or uses it for media
and some platforms may report bogus values.
- Add SLPC power_profile sysfs interface with support for base and
power_saving modes (Vinay Belgaumkar, Rodrigo Vivi)
- Add configfs attributes to add post/mid context-switch commands
(Lucas De Marchi)
Cross-subsystem Changes:
- Fix hmm_pfn_to_map_order() usage in gpusvm and refactor APIs to
align with pieces previous handled by xe_hmm (Matthew Auld)
Core Changes:
- Add MEI driver for Late Binding Firmware Update/Upload
(Alexander Usyskin)

- Fix error handling in VMA attr query (Himal)
- Move sa_info in debugfs to be per tile (Michal Wajdeczko)
- Limit number of retries upon receiving NO_RESPONSE_RETRY from GuC to
avoid endless loop (Michal Wajdeczko)
- Fix configfs handling for survivability_mode undoing user choice when
unbinding the module (Michal Wajdeczko)

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 reStructuredText 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.
