In case of tiled displays, all the tiles are linke dto each other for transcoder port sync. So in intel_atomic_check() we need to make sure that we add all the tiles to the modeset and if one of the tiles needs a full modeset then mark all other tiles for a full modeset. We also need to force modeset for all synced crtcs after fastset check. v6: * Add comments about why we do not call drm_atomic_helper_check_modeset (Matt) * Add FIXME for a corner case where tile info might vanish (Matt) v5: * Rebase v4: * Fix logic for modeset_synced_crtcs (Ville) v3: * Add tile checks only for Gen >11 v2: * Change crtc_state scope, remove tile_grp_id (Ville) * Use intel_connector_needs_modeset() (Ville) * Add modeset_synced_crtcs (Ville) * Make sure synced crtcs are forced full modeset after fastset check (Ville) Suggested-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Bugzilla: https://gitlab.freedesktop.org/drm/intel/issues/5 Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191228031204.10189-1-manasi.d.navare@intel.com |

README
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.
