I'm using v3.19-rc5 on an ARM Cortex A9 board. Unfortunately, perf is not able to capture any stack traces even though I CONFIG_STACKTRACE, CONFIG_FRAME_POINTER and CONFIG_ARM_UNWIND all enabled. I wonder if anybody else is facing similar issues.Did it work with a previous kernel?
haven't checked with this board. First time I tried to use perf for anything. -- balbi -------------- next part -------------- A non-text attachment was scrubbed...
