Let's just do a full DRRS disable/enable across all pipe updates. This guarantees that the DRRS work doesn't interfere with anything while the atomic commit is busy reprogramming the pipe. Needed so that we can start reprogramming M/N seamlessly during fastsets whenever possible. Also avoids the pre-bdw DRRS PIPECONF rmw racing with the potential PIPECONF write from the atomic commit (eg. due to GAMMA_MODE changes). v2: Include has_drrs in state dump (José) Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220315213944.17132-1-ville.syrjala@linux.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.
