In a SoC based solution, it would be useful to know the versions of the various binary firmware blobs the system is running on. On a QCOM based SoC, this info can be obtained from socinfo debugfs infrastructure. For this to work, respective subsystem drivers have to export the firmware version information to an SMEM based version information table. Having firmware version information at one place will help quickly figure out the firmware versions of various subsystems on the device instead of going through builds/logs in an event of a system crash. Fill WLAN firmware version information in SMEM version table to be printed as part of socinfo debugfs infrastructure on a Qualcomm based SoC. This change is applicable only for SNOC/QMI based targets. Example: cat /sys/kernel/debug/qcom_socinfo/cnss/name QC_IMAGE_VERSION_STRING=WLAN.HL.3.2.2.c10-00754-QCAHLSWMTPL-1 Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.2.2.c10-00754-QCAHLSWMTPL-1 Signed-off-by: Youghandhar Chintala <quic_youghand@quicinc.com> Signed-off-by: Kalle Valo <quic_kvalo@quicinc.com> Link: https://lore.kernel.org/r/20221117180534.2267-1-quic_youghand@quicinc.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 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.
