Virtualize Linaro Android on the ARM chromebook on top of Linaro ubuntu.

by Mario

Hello to everybody. Some time ago I bought the Samsung XE303C12-A01US Chromebook. I love it. Let me explain what’s my project with it. I want to virtualize LInaro android on top of Linaro Ubuntu because I would like to use them simultaneously. I know that a lot of developers are doing the inverse way,they run ubuntu on top of android,but I dislike this way because I think that Linux is better (more secure,powerful,complete) than Android. I want to start this project not for commercial reasons,but only for my pleasure. I’m not very experienced in programming,but I like the computer’s world,so I’ve studied a little which kind of scenarios we may have. To accomplish this project we could follow more ways : 1) to use LXC (linux containers) and build a chroot jail and virtualize Linaro android inside it. 2) to use XEN for ARM. In this case I need to use at least kernel 3.7 for ubuntu because the XEN supports starts from this kernel version. 3) to use QEMU+KVM,emulating Android for ARM and not Android X86. 4) to use XVISOR hypervisor 5) to use CODEZERO embedded hypervisor Since as I said I’m not experienced,I would like that someone explains to me which way is easier and which kind of problems there could be. And since I will be not never able to finish this job by myself only,I could hire a developer. I'm a student and I have not a big amount of money to offer,so I hope to find a developer who wants to help me not only for money,but also because he wants to get the challenge. Let me know. Thanks. -- Mario.

BTW, in juice-aosp #121, CONFIG_SYNC and so CONFIG_SW_SYNC aren't enabled in the kernel; this means that there is no /dev/sw_sync and sync unit test will not work. Dmitry

TC2 big-LITTLE-MP-master-v14 boot failed with 13_01 Android image

by Eric Huang

Hi, I am trying to build the kernel directly from big-LITTLE-MP-master-v14 (from http://git.linaro.org/gitweb?p=arm/big.LITTLE/mp.git;a=summary). And the kernel built from it can't seem to detect SD card. Before I spent time on this, I'd like to know whether there is any known issues here, since I am pretty with the TC2 platform. I have a TC2 with V5.0. I can get Android running with prebuilt Android image and kernel (With much help from Jon Medhurst). I then proceeded to replace the pthe kernel with a build from the big-LITTLE-MP-master-v14. I used the config file mentioned in linaro_kernel_build_cmds.sh (curl -q http://snapshots.linaro.org/android/~linaro-android/vexpress-linaro-mp-13.0…> linaro_kernel_config). The build is successful, and I then replaced the /media/boot/uImage with the new uImage. But the boot failed to detect SD card and can't boot Android up. >From 13_01's release note," big-LITTLE-MP-master-v14 that has been used for the 13.01 evaluation build ", so why replacing the released kernel build with my build doesn't work? Maybe I am missing something here? Eric Huang
