Early in the development of Xe we identified an issue with SVG state handling on DG2 and MTL (and later on Xe2 as well). In commit72ac304769("drm/xe: Emit SVG state on RCS during driver load on DG2 and MTL") and commitfb24b858a2("drm/xe/xe2: Update SVG state handling") we implemented our own workaround to prevent SVG state from leaking from context A to context B in cases where context B never issues a specific state setting. The hardware teams have now created official workaround Wa_14019789679 to cover this issue. The workaround description only requires emitting 3DSTATE_MESH_CONTROL, since they believe that's the only SVG instruction that would potentially remain unset by a context B, but still cause notable issues if unwanted values were inherited from context A. However since we already have a more extensive implementation that emits the entire SVG state and prevents _any_ SVG state from unintentionally leaking, we'll stick with our existing implementation just to be safe.

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 reStructuredText 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.
