* trace: [tcg] Declare TCG tracing helper routinesLluís Vilanova2014-08-121-0/+1
| | | | | | | | Generates file "trace/generated-helpers.h" with TCG helper declarations to trace events in guest code at execution time ('trace_${event}_exec_proxy'). Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

* trace: Multi-backend tracingLluís Vilanova2014-06-091-13/+11
| | | | | | | | | | | | | | | Adds support to compile QEMU with multiple tracing backends at the same time. For example, you can compile QEMU with: $ ./configure --enable-trace-backends=ftrace,dtrace Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system. This patch allows having both available without recompiling QEMU. Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
* trace: [tracetool] Minimize the amount of per-backend codeLluís Vilanova2014-05-071-17/+2

* tracetool: avoid str.rpartition() Python 2.5 functionStefan Hajnoczi2012-05-011-7/+10
| | | | | | | | | | | The str.rpartition() function is related to str.split() and is used for splitting strings. It was introduced in Python 2.5 and therefore cannot be used in tracetool as Python 2.4 compatibility is required. Replace the code using str.rsplit().

* tracetool: Rewrite infrastructure as python modulesLluís Vilanova2012-04-181-0/+262
The tracetool script is written in shell and has hit several portability problems due to shell quirks or external tools across host platforms. Additionally the amount of string processing and lack of real data structures makes it tough to implement code generator backends for tracers that are more complex. This patch replaces the shell version of tracetool with a Python version. The new tracetool design is: scripts/tracetool.py - top-level script scripts/tracetool/backend/ - tracer backends live here (simple, ust) scripts/tracetool/format/ - output formats live here (.c, .h) There is common code for trace-events definition parsing so that backends can focus on generating code rather than parsing input. Support for all existing backends (nop, stderr, simple, ust, and dtrace) is added back in follow-up patches.
