[DEV] Multiboot Linux on Infinity tf700 (project closed)

• Unity has some problems with performance and ram eating - this is place for optimizations.
• In-device microSD really bad works.
• WiFi disabling is fail bcmdhd kernel module.
• vt1-only, if you try to switch to vt* (`chvt 2`) - your device is freezes and reboot.
• To use unity you need nux-tools, libnux-3.8-0 and libnux-3.8-common with version 3.8.0-0ubuntu1nexus7.1 (this packages are hold)
• Sometimes I can see really bad artifacts with fonts and background on the device screen (mostly if using chromium browser). Only reboot fixes it.

You are not utilizing the linux for Tegra drivers. I think we could benefit by utilizing the latest version at least for sound. After reviewing the documentation and reviewing the drivers themselves I think we should integrate. That is unless you are trying to have two separate kernels instead of a monolithic kernel that can boot android and linux kind of like "Ubuntu for Android"

Since I have a working nvflash'd tf700 I am working on a dualboot kexec.

I still prefer the monolithic kernel approach for Android and Linux concept though, and make selection during boot as to which environment to go to. Essentially, it is possible to boot the kernel and run a specific environment and end that environment and switch to another environment.

As others have suggested I think we should integrate both into 1 tree and also try to get the tf300 on board because other than their kernel, specific tf700 configs/rules the rest of the rootfs and other portions should be identical.

I am more than willing to try, but how can I dualboot that first build ? If you provide a few step by step instructions, I am sure a lot of people will try which will help the development by giving several feedbacks.

I am currently on Clean Rom Inheritance (= CROMI) 2.7.2 which is the latest update in the Clean Rom series. Since you are using 2.4, I guess the steps woul be exactly the same as for you. I am however using Clemsyn kernel. Is the stock kernel required to be able to dual boot ?

One the OP, Ubuntu seems tobe pretty stable since a lot of features ar working. Is that really the case ? Is compiz already something I could consider using at this point of the developpment or is it still a little bit early ?

I am really interested in this project and I thank you a million time for starting actively a development allowing us to dualboot Ubuntu. Keep up you awesome work !!!

I wanted infrom everyone of the issues on the tf300t as well as ask for some guidance as to documentation for what steps I can take to fix these issues. Thanks.

Your dummy signblob header is one byte too long - there is a 0a byte before "MSM-RADIO-UPDATE" that should not be there.

Only everything is very tiny (160 dpi instead of 240), and adding ro.sf.lcd_density=240 to /system/build.prop did not help. I'll have to add it to the initrd and see if it helps. Strange, because I thought newer CleanROMs also set the dpi via /system/build.prop, but who knows. Eventually I should install CRI 3.0 anyway.

Hm, while I was writing this, the TF700 spontanously rebooted... looks like problems turning off the screen. /proc/last_kmsg contained two WARNINGs with stack trace, both containing do_blank_screen (drivers/tty/vt/vt.c:3728 and vt.c:650)

I just read that this is Clemsyn's kernel - where did you find the sources for the current version and what did you modify? There are so many different binaries in that thread and so few source drops that I totally lost track.

Hi
I've just seen the cube desktop is know supported on 0.6.2. How is it performing ? Is the latest version smoother than 0.5 ?
