Systrace tool which is used for performnce analysis of android devices are not getting executed on android emulator in ubuntu
I have tried below ways for the same but i end up with same problem
1.First of all I tried to mount /sys/kernel/debug then its readonly file system message comes .So I am not able to create the same 2.Tried to create new kernel image kernel-qmeu image with latest goldfish source code and replaced at system images place of sdk,but the emulator fails to boot. 3.Editing init.rc and adding permissions for /sys/kernel/debug and recreated the ramdisk.img,emulator boots but it still hasnt have the debugfs at /sys/kernel 4.I tried replacing new kernel image with debugfs support(through make menuconfig) and ramdisk.img with debugfs permissions.But emulator fails to boot.
Kindly help me in this concern. feel free to shoot back in case of any more clarifications

Google does not support the systrace tool in the emulator. You will need to get a Jelly Bean device that does support systrace. The Google Nexus devices seem to, and the Samsung GS3 does. My Motorola Droid RAZR M does not (so far at least). Good luck!
