Frontbuffer rendering and page flips can race with each other and this can potentialy cause issues with PSR2 selective fetch. And because pipe/crtc updates are time sentive we can't grab the PSR lock after intel_pipe_update_start() and before intel_pipe_update_end(). So here adding the lock and unlock functions and calls, the proper PSR2 selective fetch handling will come in a separated patch. v2: - fixed new functions documentation Reviewed-by: Jouni Högander <jouni.hogander@intel.com> Cc: Jouni Högander <jouni.hogander@intel.com> Cc: Mika Kahola <mika.kahola@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220405155344.47219-2-jose.souza@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.
