[Qemu-devel] [PATCH 1/4] hmp: re-enable trace-file command

[Stefan Hajnoczi]

From: Michael Roth <mdroth@linux.vnet.ibm.com>

Commit 31965ae27bc11e90674be12584bb201b83df5aef reverted a previous
renaming of CONFIG_SIMPLE_TRACE->CONFIG_TRACE_SIMPLE in a couple spots,
leading to trace-file currently being unavailable.

[Qemu-devel] [PATCH 2/4] trace: trace bdrv_open_common()

[Stefan Hajnoczi]

bdrv_open_common() is a useful point to trace since it reveals the
filename and block driver for a given BlockDriverState.

[Qemu-devel] [PATCH 3/4] trace: trace monitor qmp dispatch/completion

[Stefan Hajnoczi]

Add trace events for handle_qmp_command(), which dispatches qmp
commands, and monitor_protocol_emitter(), which produces the reply to a
qmp command.

Also remove duplicate #include "trace/control.h".

Thanks very much to Stefan Hajnoczi for his effective, detailed reviews 
without which it would have taken longer.

[Qemu-devel] [PULL 0/4] Tracing patches

[Stefan Hajnoczi]

This tracing pull request is long overdue for QEMU 1.5.

Eiichi Tsukata's ftrace backend makes it easy to correlate QEMU events with
host kernel events.  He also reports good performance.

Kazuya Saito's trace events make it easier to observe the KVM run loop.
