49 description "
50 If kernel instrumentation is enabled then the instrumentation
51 data goes into a circular buffer. A larger buffer allows
52 more data to be stored, but at a significant cost in memory.
53 The value of this option corresponds to the number of entries
54 in the table, and typically each entry will require 16 bytes
55 of memory."

62 When the instrumentation buffer is full it can either be restarted
63 from the beginning, overwriting older data, or it can stop at the
64 end. The former is useful if you want to look at the last entries
65 made while the latter is useful if you want to look at the first

73 The kernel can either collect all instrumentation events, or
74 it can filter out events at runtime based on a set of flags.
75 For example it would be possible to decide at runtime that
76 only scheduler and interrupt instrumentation flags are of
77 interest and that all other flags should be ignored. This
78 flag mechanism involves extra code and processor cycle
79 overhead in the instrumentation code, so it can be disabled
80 if the application developer is interested in all
81 instrumentation events."
