userland repo is missing edidparser and vcdbg

[lurch]

As discussed here raspberrypi/firmware@470b34d the source-code for edidparser and vcdbg is currently unavailable. AFAICT this makes them the only part of the ARM-side code that isn't yet open-sourced.

Creating this issue as a reminder that they ought to be added at some point...

[lurch]

I guess as of raspberrypi/firmware@35d9905 then this repo is also missing the source code for mmal_vc_diag

[timg236]

I'm hoping that mmal_vc_diag, vcdbg and the libdebug_sym source can be released. It's not particularly exciting code but there's a couple of dependencies in the firmware build system to untangle first. So, rather than delay mmal_vc_diag which can be quite useful for debugging camera issues I created an initial patch to release the binary.

[lurch]

Oh, I wasn't suggesting that you shouldn't have released mmal_vc_diag just because the source hasn't been published - that's entirely your prerogative.
I created this issue as more of a 'reminder' that it would be nice if all the ARM-side code could be open-sourced :)

No worries, tracking issues like this on GitHub is a good idea because it's easy to forget these sorts of tools.

Hi,

is there any progress made in publishing vcdbg?
I wanna use it on a uClibc based system.

best regards
Waldemar

Just going through some old bugs, and I see that the sources for mmal_vc_diag and libdebug_sym mentioned by @timgover above are now in the userland repo. Which just leaves the original edidparser and vcdbg as the non-source binaries.

@wbx-github perhaps you could use http://unix.stackexchange.com/questions/46478/join-the-executable-and-all-its-libraries or http://stackoverflow.com/questions/16958716/convert-a-dynamically-linked-elf-binary-to-statically-linked as a workaround? (haven't tried either option myself, just found them from googling)

[kenrestivo]

I too would like to have the source code to vcdbg. Thanks.

[Ruffio]

@lurch is this still an issue?

[XECDesign]

yes

[Ruffio]

@lurch any comments on this one?

[TheSin-]

I just noticed that my repo does not have vcdbg/edid_parser, I'd like to be able to compile and armel/armhf and arm64 version of these for my dist, is there any chance these may become open someday, for those of us that don't want to use raspbian?

[JamesH65]

@XECDesign @lurch Any chance we can close this?

[lurch]

@JamesH65 If you want to add edidparser and vcdbg to https://github.com/raspberrypi/userland/tree/master/host_applications/linux/apps then sure 😉

[JamesH65]

I've no idea where the source is! @popcornmix might have a better idea. Not sure if the licence is OS though.

[6by9]

edid_parser is copyright Broadcom and pulls in various other libraries.
Based on a quick look I'm not sure what edidparser gives you over edid-decode (available from the standard Raspbian repos).

vcdbg likewise has a large number of dependencies, and is copyright Broadcom.

[lurch]

...in which case, either this ticket should remain open indefinitely; or README.md should be updated to say that this repo will never include the source for the edidparser and vcdbg binaries that the firmware repo includes. IMVHO of course.

[pelwell]

or README.md should be updated to say that this repo will never include the source for the edid_parser and vcdbg binaries that the firmware repo includes.

I think "...does not contain the source for the edid_parser and vcdbg binaries due to licensing restrictions." would be preferable.

[JamesH65]

Which README.md needs updating? I'll fix it when I know!

[pelwell]

This one: https://github.com/raspberrypi/userland/blob/master/README.md

[JamesH65]

OK, updated the README, so closing.

[lurch]

Thanks @JamesH65 👍

[Merlinstail]

Might be an idea to add where those can be obtained from in either source or binary form

To what does "those" refer? vcdbg and edid_parser, as explained, are proprietary Broadcom code and will not be released in source form. edid-decode is available in Raspbian - it's a standard Debian package, so sudo apt-get install edid-decode. You can download (and build) the source in the usual way - see: https://wiki.debian.org/apt-src

[jakemagee]

I think @Merlinstail was asking where the binary form of vcdbg and edid_parser can be obtained. It appears to be here ... https://github.com/raspberrypi/firmware/tree/master/opt/vc/bin , and of course both are located in /usr/bin/ on the Raspbian images. Also, it appears that "edid_parser" is actually "edidparser" now? Although when ran with no arguments, the help info still references "edid_parser".

[jakemagee]

Opened raspberrypi/firmware#927 to see if the edidparser / edid_parser naming needs fixing.

[lurch]

It appears to be here ... https://github.com/raspberrypi/firmware/tree/master/opt/vc/bin

Yeah, that's the softfp version, and the hardfp version (as used in Raspbian) is at https://github.com/raspberrypi/firmware/tree/master/hardfp/opt/vc/bin
(IIRC once upon a time there were separate softfp and hardfp versions of Debian for the Raspberry Pi)

Also, it appears that "edid_parser" is actually "edidparser" now?

Hmm, looking at both https://github.com/raspberrypi/firmware/commits/master/hardfp/opt/vc/bin/edidparser and https://github.com/raspberrypi/firmware/commits/master/opt/vc/bin/edidparser it seems like the binary has always been named edidparser, so I must have made a typo when originally creating this issue :-/

EDIT: I've now edited all my previous comments as appropriate to fix the filename.

[mc-requtech]

If source is not feasible, maybe at least statically built binaries? The way things are now it's not possible to run vcdbg on a musl or uClibc system, which is rather unfortunate.

See raspberrypi/Raspberry-Pi-OS-64bit#67 (comment) ?

[mc-requtech]

@lurch Thank you. Looks very unofficial but it does work. 🎉
