      i915: content-type property for HDMI connector · 6553b123
      由 Stanislav Lisovskiy 提交于 
      Added encoding of drm content_type property from drm_connector_state
within AVI infoframe in order to properly handle external HDMI TV
content-type setting.

This requires also manipulationg ITC bit, as stated in
HDMI spec.

v2:
 * Moved helper function which attaches content type property
   to the drm core, as was suggested.
   Removed redundant connector state initialization.

v3:
 * Removed caps in drm_content_type_enum_list.
   After some discussion it turned out that HDMI Spec 1.4
   was wrongly assuming that IT Content(itc) bit doesn't affect
   Content type states, however itc bit needs to be manupulated
   as well. In order to not expose additional property for itc,
   for sake of simplicity it was decided to bind those together
   in same "content type" property.

v4:
 * Added it_content checking in intel_digital_connector_atomic_check.
   Fixed documentation for new content type enum.

v5:
 * Moved patch revision's description to commit messages.

v6:
 * Minor naming fix for the content type enumeration string.

v7:
 * Fix parameter name for documentation and parameter alignment
   in order not to get warning. Added Content Type description to
   new HDMI connector properties section.

v8:
 * Thrown away unneeded numbers from HDMI content-type property
   description. Switch to strings desription instead of plain
   definitions.

v9:
 * Moved away hdmi specific content-type enum from
   drm_connector_state. Content type property should probably not
   be bound to any specific connector interface in
   drm_connector_state.
   Same probably should be done to hdmi_picture_aspect_ration enum
   which is also contained in drm_connector_state. Added special
   helper function to get derive hdmi specific relevant infoframe
   fields.

v10:
 * Added usage description to HDMI properties kernel doc.

v11:
 * Created centralized function for filling HDMI AVI infoframe, based
   on correspondent DRM property value.

      drm/vc4: plane: Expand the lower bits by repeating the higher bits · 3257ec79
      由 Maxime Ripard 提交于 
      The vc4 HVS uses an internal RGB888 representation of the frames, and will
by default expand formats using a lower depth using zeros.

This causes an issue when we try to use other compositing software such as
pixman that fill the missing bits by repeating the higher significant bits.
As such, we can't check the display output in a reliable way by doing a
software composition and an hardware one and compare both.

To prevent this, force the same behaviour so that we can do such things.

      drm: Add and handle new aspect ratios in DRM layer · 900aa8ad
      由 Shashank Sharma 提交于 
      HDMI 2.0/CEA-861-F introduces two new aspect ratios:
- 64:27
- 256:135

This patch:
-  Adds new DRM flags for to represent these new aspect ratios.
-  Adds new cases to handle these aspect ratios while converting
from user->kernel mode or vise versa.

This patch was once reviewed and merged, and later reverted due
to lack of DRM client protection, while adding aspect ratio bits
in user modes. This is a re-spin of the series, with DRM client
cap protection.

      drm: Add aspect ratio parsing in DRM layer · 222ec161
      由 Shashank Sharma 提交于 
      Current DRM layer functions don't parse aspect ratio information
while converting a user mode->kernel mode or vice versa. This
causes modeset to pick mode with wrong aspect ratio, eventually
causing failures in HDMI compliance test cases, due to wrong VIC.

This patch adds aspect ratio information in DRM's mode conversion
and mode comparision functions, to make sure kernel picks mode
with right aspect ratio (as per the VIC).

Background:
This patch was once reviewed and merged, and later reverted due to
lack of DRM cap protection. This is a re-spin of this patch, this
time with DRM cap protection, to avoid aspect ratio information, when
the client doesn't request for it.

      drm: Expose modes with aspect ratio, only if requested · c3ff0cdb
      由 Ankit Nautiyal 提交于 
      We parse the EDID and add all the modes in the connector's modelist.
This adds CEA modes with aspect ratio information too, regardless of
whether user space requested this information or not.

This patch:
-prunes the modes with aspect-ratio information, from the
 drm_mode_get_connector modelist supplied to the user, if the
 user-space has not set the aspect ratio DRM client cap. However if
 such a mode is unique in the list, it is kept in the list, with
 aspect-ratio flags reset.
-prepares a list of exposed modes, which is used to find unique modes
 if aspect-ratio is not allowed.
-adds a new list_head 'exposed_head' in drm_mode_display, to traverse
 the list of exposed modes.

V3: As suggested by Ville, modified the mechanism of pruning of modes
    with aspect-ratio, if the aspect-ratio is not supported. Instead
    of straight away pruning such a mode, the mode is retained with
    aspect ratio bits set to zero, provided it is unique.
V4: rebase
V5: Addressed review comments from Ville:
    -used a pointer to store last valid mode.
    -avoided, modifying of picture_aspect_ratio in kernel mode,
     instead only flags bits of user mode are reset (if aspect-ratio
     is not supported).
V6: As suggested by Ville, corrected the mode pruning logic and
    elaborated the mode pruning logic and the assumptions taken.
V7: rebase
V8: rebase
V9: rebase
V10: rebase
V11: Fixed the issue caused in kms_3d test, and enhanced the pruning
     logic to correctly identify and prune modes with aspect-ratio,
     if aspect-ratio cap is not set.
V12: As suggested by Ville, added another list_head in
     drm_mode_display to traverse the list of exposed modes and
     avoided duplication of modes.
V13: Minor modifications, as suggested by Ville.
v14: As suggested by Daniel Vetter and Ville Syrjala, corrected the
     pruning logic to avoid any dependency in the order of mode with
     aspect-ratio.
