I don't really care about BT so if the lag bug can be fixed with a different kernel like Optimus Play then this could be a perfect ROM

Good evening everyone, I would just like to remind you all that OP has opened a discussion/Q&A thread in general section about this ROM so if you people have something to discuss or some questions try to post it in general section. It will be helpful for some other users who do not like to read around 1000 posts to get some knowledgeable information.
@Adam77Root correct me if I am wrong.

Have fun people.

    I'm afraid this thread will need a massive restructure soon. Getting very close. I simply love that fullscreen album art. :D

    • Graphics: OK
    • RIL: OK, data is a bit unstable
    • Wi-Fi & Wi-Fi P2P: OK
    • BT: OK
    • Audio: OK, DSP Manager effects don't work for headset
    • Storage: OK
    • HW Acceleration: OK, watched both HD and full HD videos
    • Camera: Broken, main priority now
    • Sensors: OK
    • USB: OK
    • Torch: Broken, easy to fix

    Fixed video recording with new (grouper) blobs at this very moment. :cool:

    Update on camera

    So camera is very partially fixed. Preview works for both back and front camera, all settings work (you can see the effect on the screen), but cannot take picture so far (crash). Panorama mode crashes. Video recording starts and I can click pictures, but none gets saved and it crashes again.

    What I did is basically using two whole sets of vendor blobs. One for graphics and HW acceleration and one for camera. This involved a lot of hex-editing (wrote a script for that :D). As soon as I fixed all of these (there is a <censored> dlopen() call in one of the blobs and finding that gave me a hard time :mad:), I encountered exactly the same issue as @laufersteppenwolf did with AOSP 4.3 here. The fix is in this commit, already included in CM, I pushed it to Omni Gerrit.

    What is causing the remaining issues is that the camera HAL uses Gralloc extensively for GPU memory allocation and preview displaying. We have 4 choices at the moment:
    • Old Gralloc HAL with old blobs: Always gives "NVMEM_IOC_READ failed: Operation not permitted" error, preview doesn't start.
    • Old Gralloc HAL with new blobs: Works as described above, only gives "NVMEM_IOC_READ failed" when taking picture, video, etc.
    • New Gralloc HAL with old blobs: Segmentation fault: "pc 000022b7 /system/lib/hw/gralloc.tegra.so (NvGrLock+58)", tried using CPU consumer path (source), but didn't work.
    • New Gralloc HAL with new blobs: Segfault at the same place.

    What I'm thinking of now is that we should use new gralloc HAL with new blobs, but somehow use the old NvGrLock() function, probably LD_PRELOAD could help, but first the function signature should be reverse engineered.

    I've recently finished reverse-engineering stock V20b NFC HAL and just pushed that. The source I uploaded behaves exactly the same way as it did with the binary blob. Code also contains parts from grouper source and from Nvidia device git repository. Will have to test especially regarding HCE features, but now we have one more source-built library. ;)
