26 | /* The operating system state, kept during the trace analysis, |
27 | contains a subset of the real operating system state, |
28 | sufficient for the analysis, and possibly organized quite differently. |
29 | |
30 | The state information is added to LttvTracesetContext, LttvTraceContext |
31 | and LttvTracefileContext objects, used by process_traceset, through |
32 | subtyping. The context objects already reflect the multiple tracefiles |
33 | (one per cpu) per trace and multiple traces per trace set. The state |
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 | |
46 | For each process in the process table, various informations such as exec |
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). */ |
