Linux kernel source tree
cf29a866a1
We're changing the driver to have no interrupts during early init for Xe, so we poll the PIPE_FRMSTMSMP counter instead. Interrupts cannot be enabled during FB readout because memirq's requires an allocation. This would overwrite the FB we want to read out. While it might be possible to also run do the same in i915 and run it without interrupts, the platforms i915 supports had a less clear distinction between display and graphics. For this reason I choose only to touch Xe for now.

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.
