The RISC-V Linux port doesn't support systems that have the F extension but don't have the D extension -- we actually don't support systems without D either, but Alan's patch set is rectifying that soon. For now I think we can leave this in a semi-broken state and just wait for Alan's patch set to get merged for proper non-FPU support -- the patch set is starting to look good, so doing something in-between doesn't seem like it's worth the work. I don't think it's worth fretting about support for systems with F but not D for now: our glibc ABIs are IMAC and IMAFDC so they probably won't end up being popular. We can always extend this in the future. CC: Alan Kao <alankao@andestech.com> Signed-off-by: Palmer Dabbelt <palmer@sifive.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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
