* Revert "Add a DTrace tracing backend targetted for SystemTAP compatability"Anthony Liguori2010-11-211-2/+0

* Add a DTrace tracing backend targetted for SystemTAP compatabilityDaniel P. Berrange2010-11-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Signed-off-by: Daniel P.

* .gitignore: Ignore *-timestampStefan Hajnoczi2010-10-091-0/+1
| | | | | | | | | Timestamp files were recently added to reduce make churn on source files that use tracing. The timestamp files should never be committed and should not be visible in git status.

* trace: Add simple built-in tracing backendStefan Hajnoczi2010-09-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* trace: Add trace-events file for declaring trace eventsStefan Hajnoczi2010-09-091-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces the trace-events file where trace events can be declared like so: qemu_malloc(size_t size) "size %zu" qemu_free(void *ptr) "ptr %p" These trace event declarations are processed by a new tool called tracetool to generate code for the trace events. Trace event declarations are independent of the backend tracing system (LTTng User Space Tracing, ftrace markers, DTrace). The default "nop" backend generates empty trace event functions. Therefore trace events are disabled by default. The trace-events file serves two purposes: 1. Adding trace events is easy. It is not necessary to understand the details of a backend tracing system. The trace-events file is a single location where trace events can be declared without code duplication. 2. QEMU is not tightly coupled to one particular backend tracing system. In order to support tracing across QEMU host platforms and to anticipate new backend tracing systems that are currently maturing, it is important to be flexible and not tied to one system.

* Documentation: Add build support for documentation in pdf formatStefan Weil2010-02-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | Makefile already supported dvi, html and info formats, but pdf was missing. pdf is especially convenient for printing and for documentation reviews. I hope it will help to improve qemu's documentation. Make now supports the new target 'pdf' which will create qemu-doc.pdf and qemu-tech.pdf. It is also possible to build both files individually. texi2pdf and texi2dvi are rather noisy, so normally some less important warnings are suppressed. When make is called with V=1 (verbose mode), warnings are not suppressed. The patch also sorts the documentation targets alphabetically and wraps a line which was too long.

While QEMU officially uses SVN, there are a number of unofficial git repositories that many developers use. Adding a .gitignore (derived from the svn:ignore) will make their lives a lot easier.
