-/* The statistics are for a complete time interval. These structures differ
- from the system state since they relate to static components of the
- system (all processes which existed instead of just the currently
- existing processes).
-
- The basic attributes tree to gather for several different execution modes
- (e.g., user mode, syscall, irq), thereafter called the "events tree",
- contains the following attributes: the number of events of each type,
- the total number of events, the number of bytes written, the time spent
- executing, waiting for a resource, waiting for a cpu, and possibly many
- others. The name "facility-event_type" below is to be replaced
- by specific event types (e.g., core-schedchange, code-syscall_entry...).
-
- event_types/
- "facility-event_type"
- events_count
- cpu_time
- cumulative_cpu_time
- elapsed_time
- wait_time
- bytes_written
- packets_sent
- ...
-
- The events for several different execution modes are joined together to
- form the "execution modes tree". The name "execution mode" is to be replaced
- by "system call", "trap", "irq", "user mode" or "kernel thread".
- The name "submode" is to be replaced by the specific system call, trap or
- irq name. The "submode" is an empty string if none is applicable, which is
- the case for "user mode" and "kernel thread".
-
- An "events tree" for each "execution mode" contains the sum for all its
- different submodes. An "events tree" in the "execution modes tree" contains
- the sum for all its different execution modes.

- Each trace set contains an "execution modes tree". While the traces
- come from possibly different systems, which may differ in their system
- calls..., most of the system calls will have the same name, even if their
- actual internal numeric id differs. Categories such as cpu id and process
- id are not kept since these are specific to each system. When several
- traces are taken from the same system, these categories may make sense and
- could eventually be considered.
-
- Each trace contains a global "execution modes tree", one for each
- cpu and process, and one for each process/cpu combination. The name
- "cpu number" stands for the cpu identifier, and "process_id-start_time"
- is a unique process identifier composed of the process id
- (unique at any given time but which may be reused over time) concatenated
- with the process start time. Each process has a "functions" tree which
- contains each process'function address (when the information is available).
- If not, only the 0x0 function will appear.

-
- All the events and derived values (cpu, elapsed and wait time) are
- added during the trace analysis in the relevant
- trace/processes/ * /cpu/ * /functions/ * /mode_types/ * /submodes/ *
- "events tree". To achieve this efficiently, each tracefile context
- contains a pointer to the current relevant "events tree" and "event_types"
- tree within it.
-
- Once all the events are processed, the total number of events is computed
- within each
- trace/processes/ * /cpu/ * /functions/ * /mode_types/ * /submodes/ *.
- Then, the "events tree" are summed for all submodes within each mode type
- and for all mode types within a processes/ * /cpu/ * /functions/ *
- "execution modes tree".
-
- Then, the "execution modes trees" for all functions within a
- trace/processes/ * /cpu for all cpu within a process, for all processes,
- and for all traces are computed. Separately, the "execution modes tree" for
- each function (over all cpus) for all processes, and for all traces are
- summed in the trace/processes/ * /functions/ * subtree.
-
- Finally, the "execution modes trees" for all cpu within a process,
- for all processes, and for all traces are computed. Separately,
- the "execution modes tree" for each cpu but for all processes within a
- trace are summed in the trace / cpu / * subtrees.
