ADL_P requires that we disable underrun recovery when downscaling (or using the scaler for YUV420 pipe output), using DSC, or using PSR2. Otherwise we should be able to enable the underrun recovery. On DG2 we need to keep underrun recovery disabled at all times, but the chicken bit in PIPE_CHICKEN has an inverted meaning (it's an enable bit instead of disable). v2: - Reverse the condition (clear the disable bit when supported, set disable bit when not supported).

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.
