Cover letter [PATCH uq/master v2 0/2] Add some tracepoints for clarification of the cause of troubles
This series adds tracepoints for helping us clarify the cause of troubles. Virtualization on Linux is composed of some components such as qemu, kvm, libvirt, and so on. So it is very important to clarify firstly and swiftly the cause of troubles is on what component of them. Although qemu has useful information of this because it stands among kvm, libvirt and guest, it doesn't output the information by trace or log system.
These patches add tracepoints which lead to reduce the time of the clarification. We'd like to add the tracepoints as the first set because, based on our experience, we've found out they must be useful for an investigation in the future. Without those tracepoints, we had a really hard time investigating a problem since the problem's reproducibility was quite low and there was no clue in the dump of qemu.
Changes from v1:
Add arg to kvm_ioctl, kvm_vm_ioctl, kvm_vcpu_ioctl tracepoints. Add cpu_index to kvm_vcpu_ioctl, kvm_run_exit tracepoints.
