2011-09-01trace: [stderr] add support for dynamically enabling/disabling eventsLluís1-5/+28
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>
2011-09-01trace: [simple] disable all trace points by defaultLluís1-7/+2
Note that this refers to the backend-specific state (whether the output must be generated), not the event "disabled" property (which always uses the "nop" backend). Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>
2011-09-01trace: always use the "nop" backend on events with the "disable" keywordLluís1-13/+2
Any event with the keyword/property "disable" generates an empty trace event using the "nop" backend, regardless of the current backend. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>
2011-09-01trace: generalize the "property" concept in the trace-events fileLluís1-40/+33
This adds/modifies the following functions: * get_name: Get _only_ the event name * has_property: Return whether an event has a property (keyword before the event name) Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu>

2011-04-26tracetool: allow ) in trace output stringPaolo Bonzini1-1/+1
Be greedy in matching the trailing "\)*" pattern. Otherwise, all the text in the trace string up to the last closed parenthesis is taken as part of the prototype. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-03-06tracetool: Add optional argument to specify dtrace probe namesJes Sorensen1-6/+13
Optional feature allowing a user to generate the probe list to match the name of the binary, in case they wish to install qemu under a different name than qemu-{system,user},<arch> Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Acked-by: Paolo Bonzini <pbonzini@redhat.com> Acked-by: Stefan Hajnoczi <stefaha@linux.vnet.ibm.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-01-29New trace-event backend: stderrFabien Chouteau1-2/+58
This backend sends trace events to standard error output during the emulation. Also add a "--list-backends" option to tracetool, so configure script can display the list of available backends.
