2011-11-01	trace: Add wildcard trace event support	Mark Wu	2	-3/+33
	A basic wildcard matching is supported in both the monitor command "trace-event" and the events list file. That means you can enable/disable the events having a common prefix in a batch. For example, virtio-blk trace events could be enabled using: trace-event virtio_blk_* on Signed-off-by: Mark Wu <wudxw@linux.vnet.ibm.com> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-09-21	trace: use binary file open mode in simpletrace	Stefan Hajnoczi	1	-1/+1
	For Windows portability the simple trace backend must use the 'b' file open mode. This prevents the stdio library from mangling 0x0a/0x0d newline characters. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-09-21	trace: portable simple trace backend using glib	Stefan Hajnoczi	1	-26/+48
	Convert the simple trace backend to glib so that it works under Windows. We cannot use pthread directly but glib provides portable abstractions. Also use glib atomics instead of newish gcc builtins which may not be supported on Windows toolchains. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-09-01	trace: [stderr] add support for dynamically enabling/disabling events	Lluís	2	-0/+48
	Uses the generic interface provided in "trace/control.h" in order to provide a programmatic interface as well as command line and monitor controls. Signed-off-by: Fabien Chouteau <chouteau@adacore.com> Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>
2011-09-01	trace: add "-trace events" argument to control initial state	Lluís	4	-5/+61
	The "-trace events" argument can be used to provide a file with a list of trace event names that will be enabled prior to starting execution, thus providing early tracing. This saves the user from manually toggling event states through the monitor interface or whichever backend-specific interface. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>
2011-09-01	trace: separate trace event control and query routines from the simple backend	Lluís	4	-11/+33
	Generalize the 'st_print_trace_events' and 'st_change_trace_event_state' into backend-specific 'trace_print_events' and 'trace_event_set_state' (respectively) in the "trace/control.h" file. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>
2011-09-01	trace: avoid conditional code compilation during option parsing	Lluís	4	-12/+51
	A default implementation for backend-specific routines is provided in "trace/default.c", which backends can override by setting "trace_default=no" in "configure". Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>
2011-09-01	trace: move backend-specific code into the trace/ directory	Lluís	2	-0/+403
