CEA-861-F specs defines new 4k video modes to be used with
HDMI 2.0 EDIDs. These modes start at VIC=93 and go all the
way till VIC=107.

Our existing CEA modedb contains only 64 modes (VIC=1 to VIC=64). Now
to be able to parse 4k modes using the existing techniques, we have
to complete the modedb (VIC=65 onwards).

This patch adds:
- Timings for existing CEA video modes (from VIC=65 till VIC=92)
- Newly added 4k modes (from VIC=93 to VIC=107).

Have you addressed in some other patch my concerns regarding polluting
infoframes generated for HDMI 1.4 devices (CEA-861-E) with VICs specific
only for HDMI 2.0 (CEA-861-F) ? It will happen
for all UHD modes, see [1][2] for previous discussion.

Hello Andrzej

As you already know, the aspect ratio is indexed with the VIC, which 
comes from EDID.
Now, why would a HDMI 1.4 monitor, contain a HDMI 2.0 VIC ? If it does, 
its not compliant.

Have you forgot our previous discussion? Let me cite myself:

For example 3840x2160@30Hz has no VIC in HDMI 1.4 but it can
be present in HDMI vendor specific block with HDMI_VIC 1, on the
other side it has VIC 95 in HDMI 2.0. So before your patch
AVI infoframe.video_code is set to 0, after your patch is set to 95.


And your discussion with Ville:

It does not seem to be addressed.

Hey, thanks for bringing this out again. I checked the specs again, 
there are three things here:
- The spec has a section on this, and it states that in such cases CEA 
VIC should be supplied to the AVI IF.
- Also, for HDMI infoframe blocks, we dont refer to cea_edid_modes[] 
rather we go to edid_4k_modes[]
- Again, as there is no aspect ratio parsing layer in DRM right now 
(after the revert), we are doing the right thing to give aspect as per 
CEA, which is suggested by spec too.

This phrase is not precise, but if it means that in case of
3840x2160@30Hz source should set VIC to 95 also for HDMI1.4 compliant
sinks it is in opposition to statement from HDMI1.4 specification:
> When transmitting any extended video format indicated through use of

I do not think HDMI20 could invalidate claims from HDMI1.4.


> - Also, for HDMI infoframe blocks, we dont refer to cea_edid_modes[] 
> rather we go to edid_4k_modes[]

cea_edid_modes is used in generating AVI infoframe,
edid_4k_modes is used in generating vendor infoframe

I do not understand this phrase. Are you talking about aspect ratios or
about video format?

These claims are not made in HDMI 2.0 specs, CEA is the body which 
defines VICs, AVI-IF and aspects, so its defined in CEA-861-F spec
IF you check the CEA-861-F spec, you will find this section.

As edid_cea_modes is being used in drm_hdmi_avi_if_from_display_mode, 
only place where its being used to load AVI IF (with aspect ratio 
information), I was talking about both.
But lets talk about VIC only from here.

I just realized that the CEA spec talks about picking HDMI 2.0/861-F VIC 
over HDMI14b VIC in case of 3D side-by-side format (not in 2D),

In this case, we might have to add a check while loading the VIC filed 
in AVI IF (as you suggested)

Will come back with a V2 (if required), once I have more information on 
this.

We'd like these in amdgpu as well. I've only skimmed the patch but it looks pretty good to me.

Looks like CEA-861-F also defines news VICs in the range 193-253 as
well. The way we're parsing things at the moment would actually
confuse those with the ones we already have. So it looks to me like
more work is needed to parse all the new stuff correctly.

And the way the spec lays stuff out makes me think that we might not
necessarily want to stuff anything with VIC 65 or higher into the
existing table.
