Jay Cornwall 8c7a5d9e6f drm/amdkfd: Use SQC when TCP would fail in gfx9 context save.
When a wavefront raises TRAPSTS.XNACK_ERROR with STATUS.ALLOW_REPLAY=0
subsequent memory instructions have undefined behavior. In practice
SQC stores continue to work but TCP stores do not.

Context save is permitted to fail after XNACK error because the
wavefront will be halted and subsequently terminated. However the
debugger has an interest in retrieving the wavefront VGPR/LDS state.

Detect the out-of-spec case and use SQC stores during context save
in place of TCP stores.

README

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.
