Introduce sysfs attributes to the intel-ish-ipc driver to expose the base and project firmware versions for ISH devices that load firmware from the host. The build tool embeds these versions into the ISH global manifest within the firmware binary during the firmware build process. The driver, upon loading the firmware, extracts this version information from the manifest and makes it accessible via sysfs. The base version corresponds to the firmware version provided in Intel's Firmware Development Kit (FDK), while the project version reflects the vendor-customized firmware derived from the FDK. These attributes provide userspace tools and applications with the ability to easily query the firmware versions, which is essential for firmware validation and troubleshooting. Example usages: $ cat /sys/devices/pci0000\:00/0000\:00\:12.0/firmware/base_version 5.8.0.7716 $ cat /sys/devices/pci0000\:00/0000\:00\:12.0/firmware/project_version 5.8.0.12472 Signed-off-by: Zhang Lixu <lixu.zhang@intel.com> Acked-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jiri Kosina <jkosina@suse.com>
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.
