After the state is committed, we readout the HW registers and compare the HW state with the SW state that we just committed. For Transcdoer port sync, we add master_transcoder and the salves bitmask to the crtc_state, hence we need to read those during the HW state readout to avoid pipe state mismatch. v11: * Move master trans init to get pipe_Config hooks (Ville) v10: * Initialize master_tarnscoder readout for all platforms (Ville) v9: * Initialize master_transcoder = INVALID at get config (Ville) v8: * Use master_select -1, address TRANS_EDP case (Ville) * Rename master_transcoder to _readout (Lucas) v7: * NDont read HW state for DSI v6: * Go through both parts of HW readout (Maarten) * Add a WARN if the same trans configured as master and slave (Ville, Maarten) v5: * Add return INVALID in defaut case (Maarten) v4: * Get power domains in master loop for get_config (Ville) v3: * Add TRANSCODER_D (Maarten) * v3 Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> v2: * Add Transcoder_D and MISSING_CASE (Maarten) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191018172725.1338-3-manasi.d.navare@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.
