- * Description: Statistics for locks.
- *
- * Author: Björn-Egil Dahlberg
- * Date: 2008-07-03
- * Abstract:
- * Locks statistics internal representation.
- *
- * Conceptual representation,
- * - set name
- * | - id (the unique lock)
- * | | - lock type
- * | | - statistics
- * | | | - location (file and line number)
- * | | | - tries
- * | | | - collisions (including trylock busy)
- * | | | - timer (time spent in waiting for lock)
- * | | | - n_timer (collisions excluding trylock busy)
- * | | | - histogram
- * | | | | - # 0 = log2(lock wait_time ns)
- * | | | | - ...
- * | | | | - # n = log2(lock wait_time ns)
- *
- * Each instance of a lock is the unique lock, i.e. set and id in that set.
- * For each lock there is a set of statistics with where and what impact
- * the lock aqusition had.
- *
- * Runtime options
- * - suspend, used when internal lock-counting can't be applied. For instance
- * when allocating a term for the outside and halloc needs to be used.
- * Default: off.
- * - location, reserved and not used.
- * - proclock, disable proclock counting. Used when performance might be an
- * issue. Accessible from erts_debug:lock_counters({process_locks, bool()}).
- * Default: off.
- * - copysave, enable saving of destroyed locks (and thereby its statistics).
- * If memory constraints is an issue this need to be disabled.
- * Accessible from erts_debug:lock_counters({copy_save, bool()}).
- * Default: off.

-%% TEST SUITE DESCRIPTION
-%%
-%% The test case function spawns two controlling processes: Starter and Receiver.
-%% Starter spawns a number of prio A and a number of prio B test processes. Each
-%% test process loops for a number of times, sends a report to the Receiver, then
-%% loops again. For each report, the Receiver increases a counter that corresponds
-%% to the priority of the sender. After a certain amount of time, the Receiver
-%% sends the collected data to the main test process and waits for the test case
-%% to terminate. From this data, it's possible to calculate the average run time
-%% relationship between the prio A and B test processes.
-%%
-%% Note that in order to be able to run tests with high or max prio test processes,
-%% the main test process and the Receiver needs to run at max prio, or they will
-%% be starved by the test processes. The controlling processes must not wait for
-%% messages from a normal (or low) prio process while max or high prio test processes
-%% are running (which happens e.g. if an io function is called).
