Recent improvements in the state tracking in i915 caused PSR to not be enabled when reusing firmware/BIOS modeset, this is due to all initial commits returning ealier in intel_atomic_check() as needs_modeset() is always false. To fix that here forcing the state compute phase in CRTC that is driving the eDP that supports PSR once. Enable or disable PSR do not require a fullmodeset, so user will still experience glitch free boot process plus the power savings that PSR brings. It was tried to set mode_changed in intel_initial_commit() but at this point the connectors are not registered causing a crash when computing encoder state. v2: - removed function return - change arguments to match intel_hdcp_atomic_check v3: - replaced drm includes in intel_psr.h by forward declaration(Jani) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=112253 Reported-by: <s.zharkoff@gmail.com> Cc: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Reviewed-by: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200106152128.195171-1-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.
