Chris, I should have explained the details more carefully. Here are the steps I did: 1) For host kernel, I used the branch "android-goldfish-2.6.27-kvm". 2) For android tools and images, I use those from SDK "android-sdk-linux_x86-1.0_r2" downloaded from google site whit one exeption: if I used all the images from SDK 1.0, I couldn't connect to the emulator via adb, it prompted "error: device offline". So I replaced the ramdisk image provided by SDK 1.0 with the one I compiled from android 1.5 source code, and everything went well. 3) For guest qemu, I used the branch "armkvm-upstream". But when I compiled the source code I made some modification as follows: > I removed the configuration option "--disable-gfx-check" (in the file "android-extra/scripts/configure-qemu.sh") otherwise it would prompt "ERROR: unknown option --disable-gfx-check". > I added a compile option "--disable-werror" otherwise it would treat warnings as compile errors. > I also removed line 23 "#include <linux/kvm.h>" in <AndroidVirt>/qemu/kvm.h as the compiler couldn't find the header file. 4) For guest kernel, I used the branch "v2.6.17-lpv". I think it is the modifications I did for guest qemu that caused the error. Please help me to solve it. It is great to know we will have a full ARMv6 development environment with improved performance. I will jump in soon... -Yifan On Tue, Sep 14, 2010 at 4:11 AM, Christoffer Dall <cdall at cs.columbia.edu>wrote: > Hi Yifan. > > The status right now is that we are moving to ARMv6 for the > performance updates as it was deemed necessary for acceptable > performance.
