/*
* Dynamic queue limits (dql) - Definitions
*
* Copyright (c) 2011, Tom Herbert <therbert@google.com>
*
* This header file contains the definitions for dynamic queue limits (dql).
* dql would be used in conjunction with a producer/consumer type queue
* (possibly a HW queue). Such a queue would have these general properties:
*
* 1) Objects are queued up to some limit specified as number of objects.
* 2) Periodically a completion process executes which retires consumed
* objects.
* 3) Starvation occurs when limit has been reached, all queued data has
* actually been consumed, but completion processing has not yet run
* so queuing new data is blocked.
* 4) Minimizing the amount of queued data is desirable.
*
* The goal of dql is to calculate the limit as the minimum number of objects
* needed to prevent starvation.
*
* The primary functions of dql are:
* dql_queued - called when objects are enqueued to record number of objects
* dql_avail - returns how many objects are available to be queued based
* on the object limit and how many objects are already enqueued
* dql_completed - called at completion time to indicate how many objects
* were retired from the queue
*
* The dql implementation does not implement any locking for the dql data
* structures, the higher layer should provide this. dql_queued should
* be serialized to prevent concurrent execution of the function; this
* is also true for dql_completed. However, dql_queued and dlq_completed can
* be executed concurrently (i.e. they can be protected by different locks).
