Here's a question to start it off - how to I 'perf annotate' a symbol in a module? $ perf report # Samples: 68202 # # Overhead Command Shared Object Symbol # ........ ............... ............. ...... # 84.17% qemu-system-x86 [kernel] [k] vmx_vcpu_run [kvm_intel] 4.28% qemu-system-x86 [kernel] [k] kvm_arch_vcpu_ioctl_run [kvm] 0.88% qemu-system-x86 [kernel] [k] add_preempt_count 0.75% qemu-system-x86 [kernel] [k] _spin_unlock_irqrestore 0.68% qemu-system-x86 [kernel] [k] _spin_lock_irq $ perf annotate -k ~avi/kvm/linux-2.6/vmlinux -m vmx_vcpu_run Error: symbol 'vmx_vcpu_run' not present amongst the samples. builtin symbols work. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
