2 CIRCULAR BUFFERS

9Linux provides a number of features that can be used to implement circular
10buffering. There are two sets of such features:
11
12 (1) Convenience functions for determining information about power-of-2 sized
13 buffers.
14
15 (2) Memory barriers for when the producer and the consumer of objects in the
16 buffer don't want to share a lock.
17
18To use these facilities, as discussed below, there needs to be just one
19producer and just one consumer. It is possible to handle multiple producers by
20serialising them, and to handle multiple consumers by serialising them.
21
22
23Contents:
24
25 (*) What is a circular buffer?
26
27 (*) Measuring power-of-2 buffers.
28
29 (*) Using memory barriers with circular buffers.
30 - The producer.
31 - The consumer.
32
33
34==========================
35WHAT IS A CIRCULAR BUFFER?
36==========================
37
38First of all, what is a circular buffer? A circular buffer is a buffer of
39fixed, finite size into which there are two indices:
40
41 (1) A 'head' index - the point at which the producer inserts items into the
42 buffer.
43
44 (2) A 'tail' index - the point at which the consumer finds the next item in
45 the buffer.
46
47Typically when the tail pointer is equal to the head pointer, the buffer is
48empty; and the buffer is full when the head pointer is one less than the tail
49pointer.
50
51The head index is incremented when items are added, and the tail index when
52items are removed. The tail index should never jump the head index, and both
53indices should be wrapped to 0 when they reach the end of the buffer, thus
54allowing an infinite amount of data to flow through the buffer.
55
56Typically, items will all be of the same unit size, but this isn't strictly
57required to use the techniques below. The indices can be increased by more
58than 1 if multiple items or variable-sized items are to be included in the
59buffer, provided that neither index overtakes the other. The implementer must
60be careful, however, as a region more than one unit in size may wrap the end of
61the buffer and be broken into two segments.
62
63
64============================
65MEASURING POWER-OF-2 BUFFERS
66============================
67
68Calculation of the occupancy or the remaining capacity of an arbitrarily sized
69circular buffer would normally be a slow operation, requiring the use of a
70modulus (divide) instruction. However, if the buffer is of a power-of-2 size,
71then a much quicker bitwise-AND instruction can be used instead.
72
73Linux provides a set of macros for handling power-of-2 circular buffers. These
74can be made use of by:
75
76 #include <linux/circ_buf.h>
77
78The macros are:
79
80 (*) Measure the remaining capacity of a buffer:
81
82 CIRC_SPACE(head_index, tail_index, buffer_size);
83
84 This returns the amount of space left in the buffer[1] into which items
85 can be inserted.
86
87
88 (*) Measure the maximum consecutive immediate space in a buffer:
89
90 CIRC_SPACE_TO_END(head_index, tail_index, buffer_size);
91
92 This returns the amount of consecutive space left in the buffer[1] into
93 which items can be immediately inserted without having to wrap back to the
94 beginning of the buffer.
95
96
97 (*) Measure the occupancy of a buffer:
98
99 CIRC_CNT(head_index, tail_index, buffer_size);
100
101 This returns the number of items currently occupying a buffer[2].
102
103
104 (*) Measure the non-wrapping occupancy of a buffer:
105
106 CIRC_CNT_TO_END(head_index, tail_index, buffer_size);
107
108 This returns the number of consecutive items[2] that can be extracted from
109 the buffer without having to wrap back to the beginning of the buffer.
110
111
112Each of these macros will nominally return a value between 0 and buffer_size-1,
113however:
114
115 [1] CIRC_SPACE*() are intended to be used in the producer. To the producer
116 they will return a lower bound as the producer controls the head index,
117 but the consumer may still be depleting the buffer on another CPU and
118 moving the tail index.
119
120 To the consumer it will show an upper bound as the producer may be busy
121 depleting the space.
122
123 [2] CIRC_CNT*() are intended to be used in the consumer. To the consumer they
124 will return a lower bound as the consumer controls the tail index, but the
125 producer may still be filling the buffer on another CPU and moving the
126 head index.
127
128 To the producer it will show an upper bound as the consumer may be busy
129 emptying the buffer.
130
131 [3] To a third party, the order in which the writes to the indices by the
132 producer and consumer become visible cannot be guaranteed as they are
133 independent and may be made on different CPUs - so the result in such a
134 situation will merely be a guess, and may even be negative.
135
136
137===========================================
138USING MEMORY BARRIERS WITH CIRCULAR BUFFERS
139===========================================
140
141By using memory barriers in conjunction with circular buffers, you can avoid
142the need to:
143
144 (1) use a single lock to govern access to both ends of the buffer, thus
145 allowing the buffer to be filled and emptied at the same time; and
146
147 (2) use atomic counter operations.
148
149There are two sides to this: the producer that fills the buffer, and the
150consumer that empties it. Only one thing should be filling a buffer at any one
151time, and only one thing should be emptying a buffer at any one time, but the
152two sides can operate simultaneously.
153
154
155THE PRODUCER
156------------
157
158The producer will look something like this:
159
160 spin_lock(&producer_lock);
161
162 unsigned long head = buffer->head;
163 unsigned long tail = ACCESS_ONCE(buffer->tail);
164
165 if (CIRC_SPACE(head, tail, buffer->size) >= 1) {
166 /* insert one item into the buffer */
167 struct item *item = buffer[head];
168
169 produce_item(item);
170
171 smp_wmb(); /* commit the item before incrementing the head */
172
173 buffer->head = (head + 1) & (buffer->size - 1);
174
175 /* wake_up() will make sure that the head is committed before
176 * waking anyone up */
177 wake_up(consumer);
178 }
179
180 spin_unlock(&producer_lock);
181
182This will instruct the CPU that the contents of the new item must be written
183before the head index makes it available to the consumer and then instructs the
184CPU that the revised head index must be written before the consumer is woken.
185
186Note that wake_up() doesn't have to be the exact mechanism used, but whatever
187is used must guarantee a (write) memory barrier between the update of the head
188index and the change of state of the consumer, if a change of state occurs.
189
190
191THE CONSUMER
192------------
193
194The consumer will look something like this:
195
196 spin_lock(&consumer_lock);
197
198 unsigned long head = ACCESS_ONCE(buffer->head);
199 unsigned long tail = buffer->tail;
200
201 if (CIRC_CNT(head, tail, buffer->size) >= 1) {
202 /* read index before reading contents at that index */
203 smp_read_barrier_depends();
204
205 /* extract one item from the buffer */
206 struct item *item = buffer[tail];
207
208 consume_item(item);
209
210 smp_mb(); /* finish reading descriptor before incrementing tail */
211
212 buffer->tail = (tail + 1) & (buffer->size - 1);
213 }
214
215 spin_unlock(&consumer_lock);
216
217This will instruct the CPU to make sure the index is up to date before reading
218the new item, and then it shall make sure the CPU has finished reading the item
219before it writes the new tail pointer, which will erase the item.
220
221
222Note the use of ACCESS_ONCE() in both algorithms to read the opposition index.
223This prevents the compiler from discarding and reloading its cached value -
224which some compilers will do across smp_read_barrier_depends(). This isn't
225strictly needed if you can be sure that the opposition index will _only_ be
226used the once.
