    Just got home from wrestling, ran config through code, built a kernel haven't tested it, just wanted to see if source would build a kernel, the source needs a couple modifications, after that, the source will produce a kernel, will test kernel tomorrow, going to be now.

    Code:
    LD [M]  drivers/scsi/scsi_wait_scan.ko
      LD [M]  drivers/usb/serial/baseband_usb_chr.ko
      LD [M]  net/mac80211/mac80211.ko
      LD [M]  net/wireless/cfg80211.ko
      LD [M]  net/wireless/lib80211.ko
      AS      arch/arm/boot/compressed/piggy.gzip.o
      LD      arch/arm/boot/compressed/vmlinux
      OBJCOPY arch/arm/boot/zImage
      Kernel: arch/arm/boot/zImage is ready
    598 blocks
    
    repacked boot image written at /media/b3c1b0c9-f22f-4de2-b8ee-32179fa3e787/vampirefo/lenovo/boot.img-ramdisk_FILES1-repack.img
    vampirefo@vampirefo-GA-MA78GM-US2H:/media/b3c1b0c9-f22f-4de2-b8ee-32179fa3e787/vampirefo/lenovo$ 
    
    I just flashed kernel to see if it would boot, kernel works just fine.

    Anybody willing to try and get CM10.1 running now we have the source?

    I recall from my optimus 2x days that tegra chipsets are a pain, but what are the chances of getting something up and running?

    Infact - if I put a poll in the cyanogenmod forums I wonder how many people would vote?

    If we can prove the popularity of it we may get a maintainer.

    I believe some people are getting their hand on developing CM10 for our tablet already.

    https://github.com/A2109devs/android_device_lenovo_a2109a

    But I am not sure about the detail. I also read a comment somewhere i dont remember that, the developer are waiting for some kind of approve. This information is not 100% accurate because i could understanded it wrong :p

    This is great news! I wish I could learn kernel development but its turning out to be to complicated for me. I'm trying to learn little bits at a time but I'm glad that at least your working on it and know what your doing.

    Hi vampirefo, you are talking about that the source needs a couple modifications.
    Could you please share this? Or telling what you are mean with this modifications?
    Thanks,
    Andreas

    I use a custom built linaro toolchain 'arm-lenovo-linux-gnueabi', I had to modify the makefile to allow the toolchain's optimal flags. The source is unable to build wifi module, so I removed the module as it causes build problems. To me it appears Lenovo chose not to include the necessary code to correctly compile the wifi module.

    Thanks for your fast reply.
    Could you please tell me what is special with the toolchain?

    linaro toolchains are more up to date, they use 4.7 gcc, they have a lot of optimize flags, and tweaks, you get more from the toolchain when you compile android then you get from just the kernel, but even at kernel level the kernels perform better than google compiler, I think google is switching to linaro toolchains anyway.

    CM is being worked on and will be on our devices. as far as one x I haven't looked into it yet, so can't say.

    That's great news. Is there an informative thread somewhere regarding development? I notice none in the development forum.

    I realise you are a busy man but If you get a chance to look at the tegra gpu that would be great. I notice some stutter from higher end games sometimes which sounds similar to the one x issue. It would make our tablets fly!
