The linux-next integration testing tree
6f245ea0ec
Currently, single device is probed, and once firmware is ready, the device is registered to mac80211. For Multi-Link Operation, different bands of different devices or same device are part of a single wiphy and for this, hardware device group abstraction is needed. Hardware device group abstraction - when there are multiple devices (with single radio or dual radio) that are connected by any means of interface for communicating between them, then these devices can be combined together as a single group using a group id to form a group abstraction and register to mac80211. The grouping information of multiple devices would be based on device tree during device probe (will be implemented in future patches). If no such information is available, then a single device will be part of group abstraction and registered to mac80211, else multiple devices advertised in device tree are combined and then registered to mac80211. For device group abstraction, a base structure ath12k_hw_group (ag) and the helpers are implemented. These helpers are used during device probe and mapping the group to the devices involved. An illustration of how multiple devices might be combined together in future based on group id: +------------------------------------------------------------------------+ | +-------------------------------------+ +-------------------+ | | | +-----------+ | | +-----------+ | | +-----------+ | | | | | ar (2GHz) | | | | ar (5GHz) | | | | ar (6GHz) | | | | | +-----------+ | | +-----------+ | | +-----------+ | | | | ath12k_base (ab) | | ath12k_base (ab) | | | | (Dual band device) | | | | | +-------------------------------------+ +-------------------+ | | ath12k_hw_group (ag) based on group id | +------------------------------------------------------------------------+ In the above representation, two devices are combined into single group based on group id. Add base code changes where single device would be part of a group with an invalid group id forming an group abstraction. Multi device grouping will be introduced in future.

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.
