Linux kernel source tree

Recommendation is to read FUSE4 register to check if WMTP has been enabled/disabled by HW. If enabled we don't need to do anything special, however if disabled recommendation is to also disable the WMTP mode in the FF_SLICE_CS_CHICKEN2 register, falling back to thread-group and mid-batch preemption only. However on Linux, the per-context CS_CHICKEN1 is how userspace controls pre-emption, so instead use the default lrc to disable WMTP using CS_CHICKEN1, if disabled by HW. Userspace is still free to set CS_CHICKEN1 to whatever they want later. v2: remove redundant version check and also add descriptive name(Matt) v3: remove usage of REG_FIELD_GET(Matt) Cc: Matt Roper <matthew.d.roper@intel.com> Co-developed-by: Matthew Auld <matthew.auld@intel.com> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Signed-off-by: Nirmoy Das <nirmoy.das@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://lore.kernel.org/r/20240104182615.21327-1-nirmoy.das@intel.com Signed-off-by: Matt Roper <matthew.d.roper@intel.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.
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.
