| 1079 | * Enable qemu tracing. For this to work requires running everything inside |
| 1080 | * the qemu emulator; otherwise, this method will have no effect. The trace |
| 1081 | * file is specified on the command line when the emulator is started. For |
| 1082 | * example, the following command line <br /> |
| 1083 | * <code>emulator -trace foo</code><br /> |
| 1084 | * will start running the emulator and create a trace file named "foo". This |
| 1085 | * method simply enables writing the trace records to the trace file. |
| 1086 | * |
| 1087 | * <p> |
| 1088 | * The main differences between this and {@link #startMethodTracing()} are |
| 1089 | * that tracing in the qemu emulator traces every cpu instruction of every |
| 1090 | * process, including kernel code, so we have more complete information, |
| 1091 | * including all context switches. We can also get more detailed information |
| 1092 | * such as cache misses. The sequence of calls is determined by |
| 1093 | * post-processing the instruction trace. The qemu tracing is also done |
| 1094 | * without modifying the application or perturbing the timing of calls |
| 1095 | * because no instrumentation is added to the application being traced. |
| 1096 | * </p> |
| 1097 | * |
| 1098 | * <p> |
| 1099 | * One limitation of using this method compared to using |
| 1100 | * {@link #startMethodTracing()} on the real device is that the emulator |
| 1101 | * does not model all of the real hardware effects such as memory and |
| 1102 | * bus contention. The emulator also has a simple cache model and cannot |
| 1103 | * capture all the complexities of a real cache. |
