boot-wrapper: simple multi module loading support

by Ian Campbell

Apparently kvmarm@ is the place for boot-wrapper discussions so apologies for the otherwise Xen related mail ;) The following implements support for a very basic protocol for loading multiple "modules" and providing them to the kernel. The ARM port of Xen uses this to support passing both a dom0 kernel and initrd to the hypervisor "kernel". The Xen side of this can be found in the series at: http://lists.xen.org/archives/html/xen-devel/2012-09/msg00065.html With that you can boot Xen on arm using the semi-hosting feature of the model (paths are host paths): $MODEL linux-system-semi.axf -C cluster.cpu0.semihosting-cmd_line=\ '--kernel xen-arm.bin \ --module zImage earlyprintk=xenboot console=ttyAMA1 root=/dev/mmcblk0 ro \ --dtb vexpress-v2p-aem-v7a-xen.dtb -- dom0_mem=256M' Until we know what bootloaders are going to become common in the ARM servers world it hard to know who we should be working with to define a proper protocol going forward and which bootloaders to supply patches for etc. If anyone has any pointers that would be very useful. One thing I've been considering is a port of the multiboot protocol[0] used on x86 to ARM. It seems like there is at least the kernel of an idea to port Grub2 to ARM[1] which makes a port of multiboot as well seem like a reasonable thing since grub is the reference implementation of the multiboot spec.

Starting device when connected to power

by Mark Schewe

Hello, I have a question regarding the behavior of a device if it is turned off and then is plugged into power. I want the device to turn on after power plugged in. But I really don't know where to start. I even can't figure out what part of the system (hardware/software) would be responsible for this kind of actions. There must be some event since some devices show 'charging animations'. The device I am currently working with is a rooted Galaxy Nexus. Even if you are not sure, currently every guess would help me to investigate further! Thanks, Mark
