MTYPE_NC_NV (0) marks scalar/vector L1 cache lines as non-volatile. Cache lines loaded through these apertures are intended to be invalidated before (and sometimes during) a dispatch. The non-volatile qualifier prevents these cache lines from being distinguished from those loaded through the private aperture. Use MTYPE_NC (1) instead on both Gfx7 and Gfx8. This allows the compiler to use the BUFFER_WBINVL1_VOL instruction and is a precursor to automatic per-dispatch scalar/vector L1 volatile invalidation.

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.
