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).

The failure has nothing to do with the patch, seems irrelevant.

I don't have the spec in front of me to double check the timings, but assuming the previous typos were addressed, the patch is:

As I understand it modifies edid_cea_modes array. This array
is used by couple of functions, particularly by drm_match_cea_mode,
which is used by drm_hdmi_avi_infoframe_from_display_mode.
I.e. since this patch AVI infoframes generated using drm core code will
be different - they can contain VIC codes unknown to TV.
I am not sure if it is harmful, but for sure this patch has visible
impact on drivers behavior.

Maybe it would be good to allow drivers to keep full compatibility with
HDMI 1.4?

Andrzej

Hello Andrzej,
Thanks for the comment.
If you watch the code flow carefully, this is driven by EDID. So any 
VIC, which is translated/transformed using this array, would be coming 
from the EDID itself.
So I dont think there would be a problem if the mode is defined in the 
EDID section itself, coz we are expecting the TV to know what its 
mentioning in EDID.

This is how a typical flow would look:
- hot-plug
- driver reads modes specified in EDID basic.
- driver parses various CEA extension blocks.
     - For both of the above mentioned steps, driver will probe the 
functions like do_cea_modes which uses edid_cea_modes[] array.
- driver will add the probed modes in EDID, into connector
- driver will pass the connector to userspace
- userspace will pick one of the probed modes for modeset.
- during modeset, we will set VIC part for a CEA mode, in the AVI 
infoframe section.

So in other words, the only source of a VIC (cea_mode) is from TV's own 
EDID.
This means we should never run into an unknown VIC. There can be a 0 VIC 
(for non CEA modes), but not unknown one.

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.

I agree, this particular case is true only for 4k@30 mode can be present 
in vendor specific blocks.
But as per HDMI compliance test cases, if all the timings match to the 
mode specified, the VIC should
be 95.
I was going through the HDMI 1.4 spec, and CEA-861-D/E specs with these 
corner cases, and we saw that its ok
to specify the right VIC, as per the CEA specs.

Do you also think this is the right thing to do ?
I have another patch coming up, where we can check the EDID version 
before setting VIC in AVI IF.

No. The user is free to specify any mode they wish. It doesn't have to
come from the EDID. Not sure specifying a modern VIC for an older
display is a good idea or not. If not, we could always check the cea_rev
assuming it changed whenever the list if VICs was expanded.

I agree, that user can specify a mode, out of EDID too.
I am anyways planning to add a patch, where before loading HDMI 2.0 VICs 
in AVI IF, we are checking the EDID rev.
That should solve our problem.

So if edid_rev < 2.0
     do_not_load VICs from 93 - 107, but keep it 0.

                                ^^^^

We don't have that for the old formats, and you didn't add it to most
of the new ones either.

These things are not indented correctly.

Neither is this. Also space missing where pointed.

", " missing for the remaining formats, as well as the wrong
indentation.

Noticed it all when trying to compare with what I parsed from the spec
with awk (I don't trust typing in all those numbers by hand). I've
noticed some other inconsistencies with what my script gave, but I'll
have to look those over manually if it's a failure in my script or
your table. I spotted a few inconsistencies with what we already had
as well, so I need to look those over too.

Thanks, by the time I will work over the indents pointed out.

My script gave me:
       { DRM_MODE("1920x1080", DRM_MODE_TYPE_DRIVER, 297000, 1920, 2448,
                  2492, 2640, 0, 1080, 1084, 1089, 1125, 0,
                  DRM_MODE_FLAG_PHSYNC | DRM_MODE_FLAG_PVSYNC),
         .vrefresh = 100, .picture_aspect_ratio = HDMI_PICTURE_ASPECT_64_27, },

Manual reading of the spec agrees with my script.

My script gave me:
       { DRM_MODE("3840x2160", DRM_MODE_TYPE_DRIVER, 297000, 3840, 4896,
                  4984, 5280, 0, 2160, 2168, 2178, 2250, 0,
                  DRM_MODE_FLAG_PHSYNC | DRM_MODE_FLAG_PVSYNC),
         .vrefresh = 25, .picture_aspect_ratio = HDMI_PICTURE_ASPECT_64_27, },

Manual reading of the spec agrees with my script.

Outside those two I don't see any errors in your table when compared to my
script's output. I do see some differences in the already existing modes though.
I'll look those over and send a patch if necessary.
