The following Vector subextensions for "embedded" platforms are added into RISCV_HWPROBE_KEY_IMA_EXT_0: - ZVE32X - ZVE32F - ZVE64X - ZVE64F - ZVE64D Extensions ending with an X indicates that the platform doesn't have a vector FPU. Extensions ending with F/D mean that whether single (F) or double (D) precision vector operation is supported. The number 32 or 64 follows from ZVE tells the maximum element length.

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.
