The only special case is nouveau and tda988x which used one function
for both legacy modeset code and -nv50 atomic world instead of 2
vtables. But amounts to exactly the same.

The only special case is nouveau which used one function for both

What is rather strange here is how few drivers set this up, I suspect

pile of possible issues.

      drm: Handle properties in the core for atomic drivers · 144a7999
      由 Daniel Vetter 提交于 
      The reason behind the original indirection through the helper
functions was to allow existing drivers to overwrite how they handle
properties. For example when a vendor-specific userspace had
expectations that didn't match atomic. That seemed likely, since
atomic is standardizing a _lot_ more of the behaviour of a kms driver.

But 20 drivers later there's no such need at all. Worse, this forces
all drivers to hook up the default behaviour, breaking userspace if
they forget to do that. And it forces us to export a bunch of core
function just for those helpers.

And finally, these helpers are the last places using
drm_atomic_legacy_backoff() and the implicit acquire_ctx.

This patch here just implements the new behaviour and updates the
docs. Follow-up patches will garbage-collect all the dead code.

v2: Fixup docs even better!

v3: Make it actually work ...

v4: Drop the uses_atomic_modeset() checks from the previous patch
again, since they're now moved up in the callchain.

      drm: add helper functions for YCBCR420 handling · 2570fe25
      由 Shashank Sharma 提交于 
      This patch adds helper functions for YCBCR 420 handling.
These functions do:
- check if a given video mode is YCBCR 420 only mode.
- check if a given video mode is YCBCR 420 also mode.

V2: Added YCBCR functions as helpers in DRM layer, instead of
    keeping it in I915 layer.
V3: Added handling for YCBCR-420 only modes too.
V4: EXPORT_SYMBOL(drm_find_hdmi_output_type)
V5: Addressed review comments from Danvet:
    - %s/drm_find_hdmi_output_type/drm_display_info_hdmi_output_type
    - %s/drm_can_support_ycbcr_output/drm_display_supports_ycbcr_output
    - %s/drm_can_support_this_ycbcr_output/
		drm_display_supports_this_ycbcr_output
    - pass drm_display_info instead of drm_connector for consistency
    - For drm_get_highest_quality_ycbcr_supported doc, move the variable
      description above, and then the function description.
V6: Add only YCBCR420 helpers (Ville)
V7: Addressed review comments from Ville
    - Remove cea_vic_valid() check.
    - Fix indentation.
    - Make input parameters to helpers, const.

      drm/edid: parse YCBCR420 videomodes from EDID · 832d4f2f
      由 Shashank Sharma 提交于 
      HDMI 2.0 spec adds support for YCBCR420 sub-sampled output.
CEA-861-F adds two new blocks in EDID's CEA extension blocks,
to provide information about sink's YCBCR420 output capabilities.

These blocks are:

- YCBCR420vdb(YCBCR 420 video data block):
This block contains VICs of video modes, which can be sopported only
in YCBCR420 output mode (Not in RGB/YCBCR444/422. Its like a normal
SVD block, valid for YCBCR420 modes only.

- YCBCR420cmdb(YCBCR 420 capability map data block):
This block gives information about video modes which can support
YCBCR420 output mode also (along with RGB,YCBCR444/422 etc) This
block contains a bitmap index of normal svd videomodes, which can
support YCBCR420 output too.
So if bit 0 from first vcb byte is set, first video mode in the svd
list can support YCBCR420 output too. Bit 1 means second video mode
from svd list can support YCBCR420 output too, and so on.

This patch adds two bitmaps in display's hdmi_info structure, one each
for VCB and VDB modes. If the source is HDMI 2.0 capable, this patch
adds:
- VDB modes (YCBCR 420 only modes) in connector's mode list, also makes
  an entry in the vdb_bitmap per vic.
- VCB modes (YCBCR 420 also modes) only entry in the vcb_bitmap.

V2: Addressed
    Review comments from Emil:
    - Use 1ULL<<i instead of 1<<i to make sure the output is 64bit.
    - Use the suggested method for updating dbmap.
    - Add documentation for YCBCR420_vcb_map to fix kbuild warning.

    Review comments from Ville:
    - Do not expose the YCBCR420 flags in uabi layer, keep it internal.
    - Save a map of YCBCR420 modes for future reference.
    - Check db length before trying to parse extended tag.
    - Add a warning if there are > 64 modes in capability map block.
    - Use y420cmdb in function names and macros while dealing with vcb
      to be aligned with spec.
    - Move the display information parsing block ahead of mode parsing
      blocks.

V3: Addressed design/review comments from Ville
    - Do not add flags in video modes, else we have to expose them to user
    - There should not be a UABI change, and kernel should detect the
      choice of the output based on type of mode, and the bitmaps.
    - Use standard bitops from kernel bitmap header, instead of calculating
      bit positions manually.

V4: Addressed review comments from Ville:
    - s/ycbcr_420_vdb/y420vdb
    - s/ycbcr_420_vcb/y420cmdb
    - Be less verbose on description of do_y420vdb_modes
    - Move newmode variable in the loop scope.
    - Use svd_to_vic() to get a VIC, instead of 0x7f
    - Remove bitmap description for CMDB modes & VDB modes
    - Dont add connector->ycbcr_420_allowed check for cmdb modes
    - Remove 'len' variable, in is_y420cmdb function, which is used
      only once
    - Add length check in is_y420vdb function
    - Remove unnecessary if (!db) check in function parse_y420cmdb_bitmap
    - Do not add print about YCBCR 420 modes
    - Fix indentation in few places
    - Move ycbcr420_dc_modes in next patch, where its used
    - Add a separate patch for movement of drm_add_display_info()

V5: Addressed review comments from Ville:
    - Add the patch which cleans up the current EXTENDED_TAG usage
    - Make y420_cmdb_map u64
    - Do not block ycbcr420 modes while parsing the EDID, rather
      add a separate helper function to prune ycbcr420-only modes from
      connector's probed modes.

V6: Rebase
V7: Move this patch after the 420_only validation patch (Ville)
V8: Addressed review comments from Ville
    - use cea_vic_valid check before adding cmdb/vdb modes

      drm: add helper to validate YCBCR420 modes · d8523153
      由 Shashank Sharma 提交于 
      YCBCR420 modes are supported only on HDMI 2.0 capable sources.
This patch adds:
- A drm helper to validate YCBCR420-only mode on a particular
  connector. This function will help pruning the YCBCR420-only
  modes from the connector's modelist.
- A bool variable (ycbcr_420_allowed) in the drm connector structure.
  While handling the EDID from HDMI 2.0 sinks, its important to know
  if the source is capable of handling YCBCR420 output, so that no
  YCBCR 420 modes will be listed for sources which can't handle it.
  A driver should set this variable if it wants to see YCBCR420 modes
  in the modedb.

V5: Introduced the patch in series.
V6: Squashed two patches (validate YCBCR420 and add YCBCR420
	   identifier)
V7: Addressed review comments from Vile:
    - Move this patch before we add 420 modes from EDID.
    - No need for drm_valid_cea_vic() check, function back to non-static.
    - Update MODE_STATUS with NO_420 condition.
    - Introduce y420_vdb_modes variable in this patch

      drm: handle HDMI 2.0 VICs in AVI info-frames · 0c1f528c
      由 Shashank Sharma 提交于 
      HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64).
For any other mode, the VIC filed in AVI infoframes should be 0.
HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is
extended to (VIC 1-107).

This patch adds a bool input variable, which indicates if the connected
sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a
HDMI 2.0 VIC to a HDMI 1.4 sink.

This patch touches all drm drivers, who are callers of this function
drm_hdmi_avi_infoframe_from_display_mode but to make sure there is
no change in current behavior, is_hdmi2 is kept as false.

In case of I915 driver, this patch:
- checks if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
	- VIC for 4K modes for HDMI 1.4 sinks
	- S3D information for S3D modes
  As CEA-861-F has already defined VICs for 4K videomodes, this
  patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
  until the mode is 3D.

V2: Rebase, Added r-b from Andrzej
V3: Addressed review comment from Ville:
	- Do not send VICs in both AVI-IF and HDMI-IF
	  send only one of it.
V4: Rebase
V5: Added r-b from Neil.
    Addressed review comments from Ville
    - Do not block HDMI vendor IF, instead check for VIC while
      handling AVI infoframes

      Drm has no monochrome or greyscale support so add a conversion
from the common format XR24.

Also reorder includes into the common order.
