   7 One might ask what are the new features present in LTTng and LTTV that are not
   8 in the LTT toolkit. Here are the major enhancements.<br>
   9 <br>
  10 Here is a list of the new features in LTTV :<br>
  11 Modular architecture based on plugins.<br>
  12 Reads from several traces. It supports SMP machines.<br>
  13 Synchronized graphical views. Plugins can cooperate to show the trace
  14 together.<br>
  15 Supports event types with metainformation.<br>
  16 Supports huge traces : 10-15 GB.<br>
  17 <br>
  18 <br>
  19 Here are the new features in LTTng/genevent :<br>
  20 Real ~100ns time accuracy, with monotonic increment.<br>
  21 Implements the "facility" event type metainformation.<br>
  22 Supports variable size event records.<br>
  23 Supports nested compound types : structures, array, sequences, unions, strings.<br>
  24 Supports compiler and architecture independant elementary types.<br>
  25 Supports ISO C compatible dynamic alignment of data.<br>
  26 Solid atomic (lockless) logging (NMI, traps, faults handler safe).<br>
  27 Supports writing to multiple traces at once (eventually with different
  28 filters).<br>
  29 Uses separate RelayFS channels for interrupts, modules, process and facility
  30 events.<br>
