Specification requires that max time should be masked from bdw and forward but it can be also safely enabled to hsw. This will make PSR exits more deterministic and only when really needed. If this was used to fix a issue in some panel than can only self-refresh for a few seconds, that panel will interrupt and assert one of the PSR errors handled in: 'drm/i915/psr: Handle PSR RFB storage error' and 'drm/i915/psr: Begin to handle PSR/PSR2 errors set by sink' Spec: 21664 v4: patch moved to before 'drm/i915/psr/bdw+: Enable CRC check in the static frame on the sink side' to avoid touch in 2 patches EDP_PSR_DEBUG.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
