[Dev] Kexec support for Gen8 kernel

---

Hi,

You will found here the kernel source tree archos-gpl-gen8-kernel with kexec support.
Tested on A101IT.

Awesome, will have to look into this as I've been trying to get kexecboot up and running. I want to be able to boot Ubuntu with a different kernel than Android, and so far it hasn't worked.

Edit: How are you compiling this kernel? I copied linux.config to .config and ran:

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j9

and it errors on

drivers/usb/storage/archos_hdd.c: At top level:
drivers/usb/storage/archos_hdd.c:30:27: fatal error: ../../scsi/sd.h: No such file or directory

EDIT again:

Change the <>'s to ""'s in the line in archos_hdd.c:
#include <../../scsi/sd.h>

Also apply this patch http://mailman.alsa-project.org/pipe...ay/016949.html

Then it should compile on the arm-linux-gnueabi-gcc compiler that Ubuntu ships using the above command. I have tested this on my A43 and it works perfectly, I booted Debian and ran the kexecboot bootloader (compiled from source on the device), it booted a 2.6.37+ kernel. You need the kexec-tools package installed for Debian.

Good to hear.

Between a mirror of kernel source code is available on gitorious

And for those who would to test, you can download zImage and initramfs.cpio.gz

Edit:
After flashing these files, and boot in sde you will have the recovery menu plus a Kexec boot item where upload a zImage and initramfs.cpio.gz corresponding to system you want to execute
