Add support for generating a systemtap tapset static probes

2010-11-21T15:16:56+00:00

This introduces generation of a qemu.stp/qemu-system-XXX.stp files which provides tapsets with friendly names for static probes & their arguments. Instead of probe process("qemu").mark("qemu_malloc") { printf("Malloc %d %p\n", $arg1, $arg2); } It is now possible todo probe qemu.system.i386.qemu_malloc { printf("Malloc %d %p\n", size, ptr); } There is one tapset defined per target arch, for both user and system emulators. * Makefile.target: Generate stp files for each target * tracetool: Support for generating systemtap tapsets * configure: Check for whether systemtap is available with the DTrace backend Reviewed-by: Stefan Hajnoczi Signed-off-by: Daniel P.

Add a DTrace tracing backend targetted for SystemTAP compatability

2010-11-21T15:16:56+00:00

This introduces a new tracing backend that targets the SystemTAP implementation of DTrace userspace tracing. The core functionality should be applicable and standard across any DTrace implementation on Solaris, OS-X, *BSD, but the Makefile rules will likely need some small additional changes to cope with OS specific build requirements. This backend builds a little differently from the other tracing backends. Specifically there is no 'trace.c' file, because the 'dtrace' command line tool generates a '.o' file directly from the dtrace probe definition file. The probe definition is usually named with a '.d' extension but QEMU uses '.d' files for its external makefile dependancy tracking, so this uses '.dtrace' as the extension for the probe definition file. The 'tracetool' program gains the ability to generate a trace.h file for DTrace, and also to generate the trace.d file containing the dtrace probe definition. Example usage of a dtrace probe in systemtap looks like: probe process("qemu").mark("qemu_malloc") { printf("Malloc %d %p\n", $arg1, $arg2); } * .gitignore: Ignore trace-dtrace.* * Makefile: Extra rules for generating DTrace files * Makefile.obj: Don't build trace.o for DTrace, use trace-dtrace.o generated by 'dtrace' instead * tracetool: Support for generating DTrace data files Reviewed-by: Stefan Hajnoczi Signed-off-by: Daniel P.

trace: Use TP_PROTO() and TP_ARGS() for LTTng UST

2010-10-09T08:16:55+00:00

The LTTng UserSpace Tracer formerly used TPPROTO() and TPARGS() instead of TP_PROTO() and TP_ARGS() like the kernel uses. This has been changed so QEMU needs to follow. I am not aware of a graceful way of making the transition but since no one complained that the UST build is broken, it should be fine to just switch over without compatibility for old UST headers. The newer UST headers are shipping in distro packages so it is realistic to make this change now. Signed-off-by: Stefan Hajnoczi Signed-off-by: Blue Swirl

trace: Don't strip lines containing '#' arbitrarily

2010-10-09T08:16:50+00:00

Although comment lines must be skipped, the '#' character can occur in valid format strings. Be more careful when checking for comments. Leave comments at the end of the line where they will not interfere with other processing. Signed-off-by: Stefan Hajnoczi Signed-off-by: Blue Swirl
