Root Hdmi

[rukin5197]

So, I've been very interested in HDMI lately.

It surprises me that an AOSP GB ROM has working HDMI but a CM7 ROM doesn't.. I've heard that CM7 needs HDMI mirroring for it to work, but haven't heard much about it. So any CM7 wizs feel free to correct me here.

I'm trying to build an AOSP ICS ROM and have noticed that AOSP doesn't need a hardware/qcom/display. This contains the HDMI fixes for CM7. So is there an alternative for hardware/qcom/display for AOSP? I would like to see if there's any major differences.

Anybody care to help me with this? I would like to see some gurus out there.

I'm not sure what HDMI fixes you are talking about but there is a lot that has to be added/modified to get HDMI to work on CM7. CM7 has no backend support for it and so everything has to be added. AOSP ICS and CM9 do have the needed framework (and mirroring/other) support to get HDMI to work, so it should be easier to get HDMI to work on an ICS based rom.

CM7 also doesn't have a hardware/qcom/display but looking at the CM9 source tree, it looks like the same stuff that used to reside in hardware/msm7k. I don't know about ICS AOSP but perhaps it is the same.

You can see the work I did in trying to get HDMI to work on CM7 here: https://github.com/wsimon
As you can see, there are many things that have to be added in many places to get it to work on GB based roms.

So in a sense, you're saying that GB would need some frameworks/base edits but CM9 wouldn't? Have you tried adding that lib in the android_id rom into a CM9 ROM to see what it would do?
I personally have not used HDMI and I don't think I ever will. So I can't test it.

Yes that's correct, or if it did need edits they would be small (nothing like I did in CM7).

I am not sure what needs to be done to get HDMI working on CM9- I really haven't tried fixing it on CM9 so I don't where the problem might be. All I know is that you can't use the proprietary hdmid- you have to use the one built with CM9.
