In multi-radio wiphy architecture, where a single wiphy can have multiple radios tied to it, radio specific configuration parameters and global wiphy parameters are maintained for the entire physical device and common to all radios. But, each radio in a wiphy can have different values for each radio configuration parameter, like RTS threshold. With the current debugfs directory structure, the values of global wiphy configuration parameters can be viewed, but, values of individual radio configuration parameters cannot be viewed, as radio specific configuration parameters are not maintained, separately. To address this, in addition to maintaining global wiphy configuration parameters common to all radios, create separate debugfs directories for each radio in a wiphy to maintain parameters corresponding to that radio in this directory. In implementation, maintain a dentry structure in wiphy_radio_cfg, a structure containing radio configurations of a wiphy. This struct is maintained to denote per-radio configurations of a wiphy. Create separate directories representing each radio within phy#X directory in debugfs during wiphy registration. Sample directory structure with this change: ls /sys/kernel/debug/ieee80211/phy0/radio radio0/ radio1/ radio2/ Signed-off-by: Roopni Devanathan <quic_rdevanat@quicinc.com> Link: https://patch.msgid.link/20251024044649.483557-2-quic_rdevanat@quicinc.com Signed-off-by: Johannes Berg <johannes.berg@intel.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.
