To allow the simplification of FB/plane view computation in the follow-up patches, unify the corresponding state in the intel_framebuffer and intel_plane_state structs into a new intel_fb_view struct. This adds some overhead to intel_framebuffer as the rotated view will have now space for 4 color planes instead of the required 2 and it'll also contain the unused offset for each color_plane info. Imo this is an acceptable trade-off to get a simplified way of the remap computation. Use the new intel_fb_view struct for the FB normal view as well, so (in the follow-up patches) we can remove the special casing for normal view calculation wrt. the calculation of remapped/rotated views. This also adds an overhead to the intel_framebuffer struct, as the gtt remap info and per-color plane offset/pitch is not required for the normal view, but imo this is an acceptable trade-off as above. The per-color plane pitch filed will be used by a follow-up patch, so we can retrieve the pitch for each view in the same way. No functional changes in this patch. v2: - Make the patch have _no functional change_. (fix skl_check_nv12_aux_surface() and skl_check_main_surface()). - s/i915_color_plane_view::pitch/stride/ (Ville) Suggested-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210325214808.2071517-17-imre.deak@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.
