2010-10-20	trace: Relax trace-events parsing regex in simpletrace.py	Stefan Hajnoczi	1	-2/+2
	The regular expression to parse trace event definitions assumed the format string would be a simple double-quoted string. However, we now use PRI?64 for portability which splits string literals. The regular expression can disregard the format string entirely since simpletrace.py never needs to use it.

2010-09-09	trace: Add simple built-in tracing backend	Stefan Hajnoczi	1	-0/+93
	This patch adds a simple tracer which produces binary trace files. To try out the simple backend: $ ./configure --trace-backend=simple $ make After running QEMU you can pretty-print the trace: $ ./simpletrace.py trace-events trace.log The output of simpletrace.py looks like this: qemu_realloc 0.699 ptr=0x24363f0 size=0x3 newptr=0x24363f0 qemu_free 0.768 ptr=0x24363f0 ^ ^---- timestamp delta (us) \|____ trace event name Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> trace: Make trace record fields 64-bit Explicitly use 64-bit fields in trace records so that timestamps and magic numbers work for 32-bit host builds.
