Hi all,
It seems that the Android boot animation really consumes a lot of CPU. At least when running on the ARM fast models, I see a typical steady- state load (bootanimation+surfaceflinger) of about 65% CPU.
I can kill the boot animation interactively, but does anyone know how to disable it properly? This would likely be a benefit to the test and validation work on the models.
After killing the boot animation, I can boot a fresh release to the desktop in under 8 minutes on the model, with full cache modelling disabled. A preinitialised image will boot to the unlock screen in around 2.5 minutes.
Cheers ---Dave
Hi Dave,
One way to hack it so it never starts is just to rename the bootanimation executable in /system/bin.
I just tried it and my Android boots in a reported 2m or so, about 5 minutes of real time. You get a line like this in the boot output but there are no apparent ill-effects.
[ 14.863680] init: cannot find '/system/bin/bootanimation', disabling 'bootanim'

Hi Dave,
I will remove the animation from the build if it helps in reducing boot time.

OK
I'm working on the assumption that this doesn't reduce the validity of the testing, of course.
(But I don't think it does -- the real testing will happen post-boot in any case)

Incidentally, if you just remove the service definition you get a notification from init each time something tries to start and stop the service - so you can kind of see when boot starts and stops from the output. I have no idea what is trying to start/stop bootanim though :)

Hello,
For FastModels the overhead comes mainly from changes to the framebuffer. If you don't want to remove the bootanimation service entirely you could make a boot animation with only one frame. In my experience this simple change made a drastic difference in boot time (reduced by half), without having to disable the service.
Regards.

A better way to stop bootanimation is to add "debug.sf.nobootanimation=1" into system/build.prop . This will take care of not starting/stopping the animation .I will push this into our builds and hopefully next daily builds should have the fix.

Is there a way to pass such system props through a kernel cmdline magic in a debug build? In this way we can avoid hacking such tweaks into the build, but rather enable testers etc. to do that on their side...

That would be good to know, but it seems to make more sense to me to do this by default in big.LITTLE Android builds rather than everyone specifying this each time they launch a model?

I am not aware of any way to pass this through kernel cmdline to the system,It can be done by adding support for this feature. One way is to extend l-a-m-c tool to support adding system properties.The only alternative I see is the user himself runs "setprop debug.sf.nobootanimation 1" as soon as he reaches the console needs to be done at first boot only.
