I am attempting to duplicate the android kernel provided with gem5. Following the instructions here: http://www.linux-arm.org/LinuxKernel/LinuxAndroidPlatform
I cloned the repo: git clone git://linux-arm.org/linux-2.6-armdroid.git and checkout'd 2.6.38-armdroid with: git checkout -b 2.6.38-armdroid >From here I copied the .config file supplied by gem5 into the kernel tree root and compiled with the following: make -j9 ARCH=arm CROSS_COMPILE=arm-linux-androideabi- I had to modify fs/nfs/nfsroot.c, but the compilation completed successfully using the toolchain supplied by the AOSP. I copied the vmlinux over to the gem5/system/binaries directory, but gem5 stalls for some reason when run with this kernel. The command line output: gem5 Simulator System. http://gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 compiled Apr 26 2012 12:26:52 gem5 started Jun 2 2012 19:17:17 gem5 executing on Gaia command line: build/ARM/gem5.fast configs/example/fs.py -b ArmAndroid --kernel=test.vmlinux Global frequency set at 1000000000000 ticks per second info: kernel located at: /home/ray/gem5/system/binaries/test.vmlinux Listening for system connection on port 5900 Listening for system connection on port 3456 0: system.remote_gdb.listener: listening for remote gdb on port 7000 info: Using bootloader at address 0x80000000 **** REAL SIMULATION **** info: Entering event queue @ 0.
