CM-11 progress so far

- Attached is a couple of photos of CM-11 running on Fire phone

Things that are not yet working:

(1) Audio through the speakers
- Music and system sounds through the headphones seems to be working
- This phone uses a TFA9887 audio amplifier chip. Need to figure out a way to enable it. The stock kernel sources don't seem to make any references to it so... must be controlled in userspace.
- In the amazon stock ROM it looks be controlled by two shared libs: libaudio-ExternalSpeakerAmps.so and libaudio-NxpTfa9887.so which are loaded by audio.primary.msm8974.so
- When trying to use the stock audio.primary.msm8974.so I see this in the logs:

Code:
[INDENT]D/audio_hw_primary(  496): select_devices: out_snd_device(2: speaker) in_snd_device(0: )
D/hardware_info(  496): hw_info_append_hw_type : device_name = speaker
D/ACDB-LOADER(  496): ACDB -> send_audio_cal, acdb_id = 53, path =  0
E/ExternalSpeakerAmpControl(  496): Failed to open the speaker amp control (0) at address = 0x34.  Error = 108
E/ExternalSpeakerAmpControl(  496): Failed to open the speaker amp control (1) at address = 0x35.  Error = 108
D/audio_speaker_platform(  496): Loading speaker use case "music"[/INDENT]

Update

Progress for today.

- WiFi is working
- Sensors are working
- Baseband seems to be detected correctly - put my sim card in and got a SIM network unlock screen - screenshot attached. I got the phone for nearly next to nothing. But looks like I need it unlocked to use my SIM.
- Bluetooth is working - paired with a keyboard and works good.
- Gapps working

- Front and rear camera not working yet
- Sound, need to figure this out - this is a show stopper at the moment. No Ringing of phone etc

On the amplifier issue did a little digging and other devices like the HTC M7 tend to have a kernel driver which implements an IOCTL interface to userspace but this doesn't seem to the case in the Fire Phone's stock kernel in which I couldn't find any reference to the TFA9887.

I'll have to research a bit more.

I'll do an early preview release at a good point.

Great work will this also work on the US 4.6.1 software version 461013820.bin. thanks
Should work. If it doesn't, you should be able to boot into the amazon recovery and sideload your stock firmware.

Let me know your results. Once you confirm its working I'll update the OP.

@ggow
Just making an observation, the external speakers do not depend individually on the stock audio libs (libaudio-ExternalSpeakerAmps.so ; libaudio-NxpTfa9887.so etc..) but might also depend on Dolby frameworks that the stock rom calls.

I want to test it out but i'm having problems with hyper-v atm.

Thanks.
I had a brief look at the chain of dependencies. This is all I could find. However I will take a look tomorrow. And let you know what I find :)

CM-11 Progress update

- Front and rear cameras are now working.
- Google camera and OpenCamera are perfectly fine
- Stock camera app is displaying the preview image upside down.
- Google camera seems to give significantly better photo quality than the stock camera app.
- I will probably remove stock camera app from the build.

Good News

- I have audio on the the speakers... Exactly as I thought- the Tfa9887 is controlled only from the two shared libs I previously mentioned. The fix was to set the correct permissions on /dev/i2c-8 and set a property which indicates audio has been initialized correctly.
- I have a few things to tidy up - like a couple of force closes etc
- Need to do a bit of testing, test video, a couple games etc
- After all of that it should be ready to go.
- I won't have tested make calls, sms and mobile data - so the first release will be a BETA.

EDIT: I should start a [DEV] thread for this so I don't clog up this thread anymore.
