SEL_FETCH_CTL registers are armed immediately when plane is disabled. SEL_FETCH_* instances of plane configuration are used when doing selective update and normal plane register instances for full updates. Currently all SEL_FETCH_* registers are written as a part of noarm plane configuration. If noarm and arm plane configuration are not happening within same vblank we may end up having plane as a part of selective update before it's PLANE_SURF register is written. Fix this by splitting plane selective fetch configuration into arm and noarm versions and call them accordingly. Write SEL_FETCH_CTL in arm version. v3: - add arm suffix into intel_psr2_disable_plane_sel_fetch v2: - drop color_plane parameter from arm part - dev_priv -> i915 in arm part Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Mika Kahola <mika.kahola@intel.com> Cc: Vinod Govindapillai <vinod.govindapillai@intel.com> Cc: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Cc: Luca Coelho <luciano.coelho@intel.com> Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Reviewed-by: Luca Coelho <luciano.coelho@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230130080651.3796929-1-jouni.hogander@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.
