This patchset is a set of bug-fixes, additions, and changes I've made while examining various EDIDs I have encountered.
I made a fork at https://github.com/joevt/edid-decode with the commits listed below.
For the first commit, I have a script to convert C printf format strings in the source code to regular expressions and then use those to find EDIDs in my collection (or in linuxhw/EDID) that contain matches to those regular expressions that are not matched by the EDIDs in the data directory. It prioritizes EDIDs that contain the most matches.
joevt (11):
edid-decode: add more example EDIDs
edid-decode: ignore dSYM
edid-decode: change install directories for macOS
edid-decode: add bounds checking
edid-decode: fix standard timing vertical pixels
edid-decode: linefeed before fail
edid-decode: always linefeed after hex_block
edid-decode: output full frequencies for 4:2:0
edid-decode: allow undefined aspect ratio
edid-decode: add warnings to VESA VSDB
edid-decode: cta and displayid changes

apple-xdr-5k-tile0
apple-xdr-5k-tile1
- Apple Pro Display XDR. These EDIDs may be used for 6K single tile mode or 5K tiled mode (Thunderbolt connection).
- The Tiled Display Topology has info for 6K tiled but the tiled timings are sized for 5K. Apple uses an mtdd file for tile information.
apple-xdr-6k
- Apple Pro Display XDR. This EDID may be used for 6K. It contains no tile topology or tile timings.
apple-xdr-6k-tile0
apple-xdr-6k-tile1
- These EDIDs may be used for tiled 6K mode (two HBR3 x4 signals over Thunderbolt 3 with no DSC).
- Largest EDID ever with 6 extension blocks.
- Has one 60Hz mode for 1440p (for DisplayPort 1.1 compatibility) and five refresh rates for each of 4K, 5K, 6K, 5K/2 tiled modes, 6K/2 tiled modes.
- The five refresh rates are for 47.95, 48, 50, 59.94, 60Hz.
- For each resolution, only the delay between frames (just the vertical front porch) is different between different refresh rates.
- Tile topology has info for 6K tiled mode only, not 5K tiled mode even though 5K tile timings are also included.
For any of xdr EDIDs above:
- The EDIDs may exclude BT2020RGB from the Colorimetry Data Block and/or HDR and SMPTE ST2084 from the Electro optical transfer functions.
- If HDR is removed from Electro optical transfer functions, then Desired content max luminance is reduced from 1600 nits to 507.620 nits and Desired content min luminance is increased from value 1 to value 2 (both values are 0 nits).
- An alternative SDR mode may have max luminance and max frame-average luminance reduced from 507.620 nits to 161.049 nits while min luminance is increased from value 2 to value 4 (both values are 0 nits).
- Perhaps other presets (selectable in macOS via the Displays preferences panel or in Windows by the Boot Camp control panel) will make other changes to the EDIDs.

Don't do ceiling to nearest 8 pixels for active vertical lines. See examples elo-4600l-hdmi and kogan-kaled24144f-hdmi.
Section 3.9 and 3.10.3.6 of EDID 1.4 does not say vertical lines must be a multiple of 8. This line of code appears to have been added to satisfy the 3rd example in VTB-EXT spec but that example has an incorrect HAP indicator decimal value so it cannot be trusted. Also, all 3 examples have an incorrect vertical refresh value as noted in parse-vtb-ext-block.cpp. The VESA DMT spec has the following examples that are not a multiple of 8 lines which support this change:
1400x1050 4:3
1440x900 16:10
1600x900 16:9
1680x1050 16:10

hex_block should not return without printing a newline (which occurs when the length is zero). This causes a missing newline after "Application Version: 1" with cta_hdr10plus for an EDID I have.
Any place that calls hex_block will have the same problem if it's possible for the length to be zero.
In other words, a hex_block needs to have a linefeed even if it has zero length, because the caller assumes it will go to the next line as it does when the hex block is not zero length.

Don't half hfreq for 4:2:0 timings - the character clock is halved, but the number of characters per line is also halved (two luminance values per character for 4:2:0), so there's no change in hfreq.
Don't half pixel clock because it looks weird. Character clock is halved but the number of pixels remains the same (two luminance values per character for 4:2:0).
Continue to use the half hfreq and half pixel clock for the ranges calculations because some non-HDMI 2.0 displays have max pixel clock halved when they have 4:2:0 modes and because other reasons that lead to adding this code in the first place?

Distinguish between "undefined" and "reserved" aspect ratios. See examples apple-xdr-6k-tile0, lg-ultrafine-5k-v1-thunderbolt-dp1-tile0, asus-xg438q-dp
"undefined" is for an aspect ratio that doesn't exist in the list of known aspect ratios. This does not deserve a fail.
"reserved" should not be used and still deserves the fail.

Goal: make OUI blocks equal to normal blocks to simplify decoding and make handling of all types of blocks consistent. This will reduce duplicated code (only one place for checking duplicate blocks, only one place for handling unknown blocks, etc.)
oui.h
- This contains a list of OUI and CID and PNP values.
- It is included in various places with varying definitions of the oneoui macro.
edid-decode.h
- Add list of OUI constants using oui.h.
- Other changes described below.
parse-cta-block.cpp
- Modified oui_name. Returns a name and a number for a OUI.
- Added data_block_oui. For data blocks with an OUI, does size check, OUI endianness check, and PNP vs OUI check. Returns a value representing the OUI (if it is known).
- Modify cta_block. Reduce code by flattening the switch statement. This means constructing a case value from three values.
Side effects include making reporting of "Only one instance of this Data Block is allowed." more consistant (always report this fail after the block type is output instead of sometimes before and sometimes after). See example acer-xv273k-dp2-corrupted.
First, get the extended type and append it to the tag type (i.e. add 0x700 if extended), then get the OUI if it's vendor specific, and convert it to a number that can be appended (bitwise or) to the tag/extended type value.
- Init static variables
- Replace last_block_was_hdmi_vsdb with previous_cta_tag; this means instead of remembering if the last block was hdmi vsdb, we just remember the previous block's tag.
- Replace first_block with cta_block_number; this means instead of remembering if this is the first block or not, we just remember the current block number.
- Remove name and oui, we'll just get the data_block string and a oui index directly.
- Report OUI for extended tag 11h (Vendor-Specific Audio Data Block)
- Fix capitalization of "Audio information is present" fail message.
- Add bounds check on length field (must be at least 1 for extended tags).
- Don't parse after OUI if there's not enough length for OUI.
- Adjust x offsets in cta_hdmi_block so it is like other OUI extended blocks such that x points to after the OUI.
- A block that outputs only hex is reported as an unknown block type even if we know the OUI. See example acer-xb321hk-dp.
parse-disableid-block.cpp
- Add displayid_block to do a single data block - like cta_block does for cta extension block
- Vendor specific data block for DisplayID 1.3 is assumed to be PNP (string order). See example apple-macbookpro-16inch-2019.
- Vendor specific data block for DisplayID 2.0 is assumed to have OUI (little endian).
- Interpret Vendor specific data block 0x7e or 0x7f even if DisplayID is not correct for that type (there's already a FAIL message to identify the problem). See example apple-xdr-6k.
- Add bounds check: if length is < 3, only check x[1] if length is 2.
Don't report "Not enough bytes remain (1) for a DisplayID data block or the DisplayID filler is non-0." if the bytes are zero (also change the word "or" to "and"). See example apple-xdr-6k-tile0.
- Report datablock name before failing.
- For unknown vendor specific data blocks, don't output the OUI part as hex since the new data_block_oui function has already reported it. See example apple-macbookpro-16inch-2019.
- Replace first_data_block with disp.block_number

This last change is a spurious change, I'll drop this and keep the rest.

This line of code appears to have been added to satisfy the 3rd example in VTB-EXT spec but that example has an incorrect HAP indicator decimal value so it cannot be trusted. Also, all 3 examples have an incorrect vertical refresh value as noted in parse-vtb-ext-block.cpp. The VESA DMT spec has the following examples that are not a multiple of 8 lines which support this change:

I need to look closer at this. I think it was added to help with 1360x768, which without
this line maps to 1360x765.
I'll get back to you on this.

Hmm, with this change I get this:
edid-decode -c Digital/Acer/ACR0282/B12D637C1F12 with the linuxhw database:
Vendor-Specific Data Block (HDMI), OUI 00-0C-03:
Source physical address: 2.0.0.0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
That looks pretty ugly.

I did some more reading on this, and appendix D of the EDID 1.4 spec
says this (D-8):
"If calculated aspect ratio is not 16 : 10 AR, 4 : 3 AR, 5 : 4 AR or 16 : 9 AR
what timing description should be used?"
"Ref.: Section 3.9 (E-EDID Standard Release A, Revision 2)
The Standard Timings Identification code may not be used to
identify timings which do not match one of these standard aspect
ratios. Support for such timings must be indicated elsewhere,
e.g., by use of a Detailed Timing Descriptor."
So you are correct with your change, but I think it would make
sense to add a new check:
// See also Ref. D-8 in the EDID-1.4 spec
if (vact & 1)
warn("Standard Timing %ux%u has a dubious odd vertical resolution.\n", hact, vact);
So that way an attempt to use ST to describe 1360x768 will result in a warning.

I've decided not to merge this patch. It does too many things at the same time,
so it really should be split up into smaller pieces.
I'm also getting ugly lines like this:
Unknown CTA-861 Data Block (tag 0x00): Unknown block type: Unknown CTA-861 Data Block (tag 0x00).
or this:
Vendor-Specific Data Block (NVIDIA), OUI 00-04-4B: Unknown block type: Vendor-Specific Data Block (NVIDIA),
OUI 00-04-4B.
(which shouldn't be a warning anyway)

While it does reduce the code size a bit, it really isn't by all that much,
so I am not convinced that all the churn is worth it.
If this is split up into first fixes and small improvements, and then rework
the tag handling, then I can take another look at whether it makes sense to
apply this.
I've applied patches 1, 2, 3, 4, 6, 8, 9 and 10. The others need more work.

Hans

Thanks. That last change was made because I don't like to do aligning between lines that have different indents. That way you don't have to mix tabs and spaces or worry about different tab widths used by different people using different editors.

This last change is a spurious change, I'll drop this and keep the rest.
No need for you to do anything.

Yes, that's ugly. I will do a search for the EDID that prompted me to make this change. Maybe it's not a problem anymore.
...
Seems like the problem I had was fixed in cta_hdr10plus. I'll do more checking and testing with other calls to hex_block.

Hmm, with this change I get this:
edid-decode -c Digital/Acer/ACR0282/B12D637C1F12 with the linuxhw database:
Vendor-Specific Data Block (HDMI), OUI 00-0C-03:
Source physical address: 2.0.0.0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
That looks pretty ugly.

I found no place that requires this change to hex_block.
This patch should be ignored.
I did find one call to hex_block that should be modified:
cta_hdr10plus outputs hex on the same line as the "Application Version: %u".
It either needs to always output a linefeed before calling hex_block like this:
printf(" Application Version: %u\n", x[0]);
hex_block(" ", x + 1, length - 1);
Or it needs to set step to the same value as length, like this:
printf(" Application Version: %u", x[0]);
if (length > 1)
hex_block(" ", x + 1, length - 1, true, length - 1);
else
printf("\n");
Those are probably the only acceptable ways to call hex_block (first is multi-line or no-line, second is one-line)
It should also probably check the length:
if (length == 0) {
fail("Empty Data Block with length %u.\n", length);
return;
}

edid-decode -c Digital/Acer/ACR0282/B12D637C1F12 with the linuxhw database:
Vendor-Specific Data Block (HDMI), OUI 00-0C-03:
Source physical address: 2.0.0.0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
Unknown CTA-861 tag 0x00, length 0
That looks pretty ugly.

Good find. I agree with that warning.

This line of code appears to have been added to satisfy the 3rd example in VTB-EXT spec but that example has an incorrect HAP indicator decimal value so it cannot be trusted. Also, all 3 examples have an incorrect vertical refresh value as noted in parse-vtb-ext-block.cpp. The VESA DMT spec has the following examples that are not a multiple of 8 lines which support this change:

I did some more reading on this, and appendix D of the EDID 1.4 spec
says this (D-8):
"If calculated aspect ratio is not 16 : 10 AR, 4 : 3 AR, 5 : 4 AR or 16 : 9 AR
what timing description should be used?"
"Ref.: Section 3.9 (E-EDID Standard Release A, Revision 2)
The Standard Timings Identification code may not be used to
identify timings which do not match one of these standard aspect
ratios. Support for such timings must be indicated elsewhere,
e.g., by use of a Detailed Timing Descriptor."
So you are correct with your change, but I think it would make
sense to add a new check:
// See also Ref. D-8 in the EDID-1.4 spec
if (vact & 1)
warn("Standard Timing %ux%u has a dubious odd vertical resolution.\n", hact, vact);
So that way an attempt to use ST to describe 1360x768 will result in a warning.

1) Regarding large changes:
I will try making smaller changes with commits that build on each other. Git is good for code changes but not for code moving/rearranging. Many of the changes don't actually change anything (wanting to keep the output the same as before). Some fixes are easier to apply after doing the rearranging so I'll think about what order to make each change.
2) Regarding code reduction:
The code reduction for cta tag parsing (288 lines originally) is 43%. Not insignificant.
The code reduction for displayid tag parsing (241 lines originally) is 8% which is not as much (no extended tags and only one oui), but it's nice that it's arranged like cta tag parsing.
3) Regarding ugly lines:
The ugly lines were because of hex_block issues discussed in [PATCH 07/11]. What you should see (when hex_block is working properly) is something like this:
Unknown CTA-861 Data Block (tag 0x00):
WARN: Unknown block type: Unknown CTA-861 Data Block (tag 0x00).
The warning is "Unknown block type: %s\n" where %s is the block type which is determined in the first switch statement.
Here's an example from _EDID_BNQ_802e with non-zero length hex:
Before patches:
Unknown CTA-861 tag 0x00, length 5
c0 00 e6 06 05 '.....'
WARN: Unknown CTA-861 Data Block 0.
Length is unnecessary since you can just count the hex bytes.
Block 0 sounds like it's referring to block index 0 instead of block tag 0x00.
After all patches:
Unknown CTA-861 Data Block (tag 0x00):
c0 00 e6 06 05 '.....'
WARN: Unknown block type: Unknown CTA-861 Data Block (tag 0x00).
With these changes, we have a consistent naming scheme for the block type (having " Data Block" suffix and adding tag in cases where the name is not enough to determine the tag) and the warning refers to that block type. Might be better if the warning comes after the block type instead of after the hex.
4) Regarding the NVIDIA oui:
You are saying that only blocks with an invalid tag should have the unknown block type warning. Not knowing how to parse a tag/oui should not be the cause of a warning. I can agree with that. If the user sees only hex then they know that edid-decode doesn't know how to decode it.

I've decided not to merge this patch. It does too many things at the same time,
so it really should be split up into smaller pieces.
I'm also getting ugly lines like this:
Unknown CTA-861 Data Block (tag 0x00): Unknown block type: Unknown CTA-861 Data Block (tag 0x00).
or this:
Vendor-Specific Data Block (NVIDIA), OUI 00-04-4B: Unknown block type: Vendor-Specific Data Block (NVIDIA),
OUI 00-04-4B.
(which shouldn't be a warning anyway)

While it does reduce the code size a bit, it really isn't by all that much,
so I am not convinced that all the churn is worth it.
If this is split up into first fixes and small improvements, and then rework
the tag handling, then I can take another look at whether it makes sense to
apply this.
I've applied patches 1, 2, 3, 4, 6, 8, 9 and 10. The others need more work.
