Linux kernel source tree

LoongArch's MSG interrupt features are used across multiple subsystems. Clarify these features to avoid misuse, existing users will be adjusted if necessary. MSGINT: Infrastructure, means the CPU core supports message interupts. Indicated by CPUCFG1.MSGINT. AVECINT: AVEC interrupt controller based on MSGINT, means the CPU chip supports direct message interrupts. Indicated by IOCSR.FEATURES.DMSI. REDIRECTINT: REDIRECT interrupt controller based on MSGINT and AVECINT, means the CPU chip supports redirect message interrupts. Indicated by IOCSR.FEATURES.RMSI. For example: Loongson-3A5000/3C5000 doesn't support MSGINT/AVECINT/REDIRECTINT; Loongson-3A6000 supports MSGINT but doesn't support AVECINT/REDIRECTINT; Loongson-3C6000 supports MSGINT/AVECINT/REDIRECTINT.

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.
