Hi, I want to use ftrace's function tracer to monitor the kernel while I perform various experiments. I decided to start with the emulator and work towards using a physical device. My problem is, everytime I enable the function tracer, everything hangs, without output.
I am using the latest goldfish kernel I could find 2.6.29 and have built it with ftrace support (in menuconfig (kernel hacking -> tracers -> Kernel Function Tracer)). I boot it using the emulator and a standard (api level 9 I think) avd I made, passing the -kernel parameter. I can use the sched_switch tracer without any problems. It's just when I enable the function tracer (echo function > current_tracer). The whole thing hangs. Any help would be greatly appreciated! -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
