dd025f91 | 26 | /* The operating system state, kept during the trace analysis, |
dc877563 | 27 | contains a subset of the real operating system state, |
28 | sufficient for the analysis, and possibly organized quite differently. | |
29 | ||
ffd54a90 | 30 | The state information is added to LttvTracesetContext, LttvTraceContext |
d3e01c7a | 31 | and LttvTracefileContext objects, used by process_traceset, through |
dc877563 | 32 | subtyping. The context objects already reflect the multiple tracefiles |
33 | (one per cpu) per trace and multiple traces per trace set. The state | |
308711e5 | 34 | objects defined here simply add fields to the relevant context objects. |
35 | ||
36 | There is no traceset specific state yet. It may eventually contains such | |
37 | things as clock differences over time. | |
38 | ||
39 | The trace state currently consists in a process table. | |
40 | ||
41 | The tracefile level state relates to the associated cpu. It contains the | |
42 | position of the current event in the tracefile (since the state depends on | |
43 | which events have been processed) and a pointer to the current process, | |
44 | in the process table, being run on that cpu. | |
45 | ||
1aeb0ff5 | 46 | For each process in the process table, various information such as exec |
308711e5 | 47 | file name, pid, ppid and creation time are stored. Each process state also |
48 | contains an execution mode stack (e.g. irq within system call, called | |
49 | from user mode). */ | |

186 | A process can make system calls (in some rare cases nested) and receive | |
187 | interrupts/faults. For instance, a process may issue a system call, | |
188 | generate a page fault while reading an argument from user space, and | |
189 | get caught by an interrupt. To represent these nested states, an | |
190 | execution mode stack is maintained. The stack bottom is normal user mode | |
191 | and the top of stack is the current execution mode. | |
192 | ||
193 | The execution mode stack tells about the process status, execution mode and | |

195 | defined as enumerations but may need extensions (e.g. new process state). | |
