StarFive: Things are a bit slower for StarFive this window, there's only the addition of audio related DT nodes to speak of here. Generic: The SiFive, StarFive and Microchip devicetrees have had my replacement ISA extension detection properties added. Unfortunately, the old "riscv,isa" property never defined exactly what the extensions it contained meant, and people were want to fill it in incorrectly (and call upstream kernel devs idiots for not doing the same). The new properties have explicit definitions and hopefully will stand up better to some of the variation from RVI. Sophgo: Two new SoCs, one is probably the first of several with up/down tuned variants, that have a pair of T-Head c906 cores and appear aimed at the IP camera, smart <insert whatever> etc markets. They are intended to run in AMP mode, with an RTOS on the less powerful core. The other is far more interesting to kernel developers however, the 64-core SG2042, with more recent c920 cores from T-Head at 2 GHz. For both, support is at a very basic stage - some of the same developers are working on them as other T-Head powered SoCs, but hopefully things will move beyond a basic console boot. The goal is for Chen Wang to take over maintaining the Sophgo support once they have some more experience with the process.

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.
