Sean Keely 3da13a1e2a drm/amdkfd: Account for SH/SE count when setting up cu masks.
[ Upstream commit 1ec06c2dee679e9f089e78ed20cb74ee90155f61 ]

On systems with multiple SH per SE compute_static_thread_mgmt_se#
is split into independent masks, one for each SH, in the upper and
lower 16 bits.  We need to detect this and apply cu masking to each
SH.  The cu mask bits are assigned first to each SE, then to
alternate SHs, then finally to higher CU id.  This ensures that
the maximum number of SPIs are engaged as early as possible while
balancing CU assignment to each SH.

v2: Use max SH/SE rather than max SH in cu_per_sh.

v3: Fix comment blocks, ensure se_mask is initially zero filled,
    and correctly assign se.sh.cu positions to unset bits in cu_mask.

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.
