To build, you'll need a compiled DroidX kernel from source, as well as the android NDK.
To build, make sure you have downloaded the DroidX GB kernel source and compiled it. There are guides everywhere on how to build Android kernels. Just make sure you use the proper cross compiler.
When you build, make sure to use
Once the kernel is built, clone my repo and edit envsetup.sh to reflect the correct paths to your kernel source directory and the android NDK.
Then, source it:
Then, just run
and cross your fingers. You should then have a fresh kexec_load.ko file!
To see if it loads, you'll need to copy it to your sdcard, and then on the phone, using a console, do the following:
su (click allow)
If you don't get any errors, it inserted! Now, of course, to actually use it, we'd need the kexec-tools built, which I haven't gotten ready yet...but they're coming! To remove the module (no reason to leave it in memory for now):
Happy hacking, and help is always appreciated!
I realize people gave up slightly on the whole kexec thing over radio worries, but I now have the module compiling and inserting without error into the Droid2/DroidX gingerbread kernel. Next comes cross compiling the kexec-tools for userspace, to allow us to attempt inserting a different kernel.
