83 * Aggregate clat samples to report percentile(s) of them.
84 *
85 * EXECUTIVE SUMMARY
86 *
87 * FIO_IO_U_PLAT_BITS determines the maximum statistical error on the
88 * value of resulting percentiles. The error will be approximately
89 * 1/2^(FIO_IO_U_PLAT_BITS+1) of the value.
90 *
91 * FIO_IO_U_PLAT_GROUP_NR and FIO_IO_U_PLAT_BITS determine the maximum
92 * range being tracked for latency samples. The maximum value tracked
93 * accurately will be 2^(GROUP_NR + PLAT_BITS -1) microseconds.
94 *
95 * FIO_IO_U_PLAT_GROUP_NR and FIO_IO_U_PLAT_BITS determine the memory
96 * requirement of storing those aggregate counts. The memory used will
97 * be (FIO_IO_U_PLAT_GROUP_NR * 2^FIO_IO_U_PLAT_BITS) * sizeof(int)
98 * bytes.
99 *
100 * FIO_IO_U_PLAT_NR is the total number of buckets.
101 *
102 * DETAILS
103 *
104 * Suppose the clat varies from 0 to 999 (usec), the straightforward
105 * method is to keep an array of (999 + 1) buckets, in which a counter
106 * keeps the count of samples which fall in the bucket, e.g.,
107 * {[0],[1],...,[999]}. However this consumes a huge amount of space,
108 * and can be avoided if an approximation is acceptable.
109 *
110 * One such method is to let the range of the bucket to be greater
111 * than one. This method has low accuracy when the value is small. For
112 * example, let the buckets be {[0,99],[100,199],...,[900,999]}, and
113 * the represented value of each bucket be the mean of the range. Then
114 * a value 0 has an round-off error of 49.5. To improve on this, we
115 * use buckets with non-uniform ranges, while bounding the error of
116 * each bucket within a ratio of the sample value. A simple example
117 * would be when error_bound = 0.005, buckets are {
118 * {[0],[1],...,[99]}, {[100,101],[102,103],...,[198,199]},..,
119 * {[900,909],[910,919]...} }. The total range is partitioned into
120 * groups with different ranges, then buckets with uniform ranges. An
121 * upper bound of the error is (range_of_bucket/2)/value_of_bucket
122 *
123 * For better efficiency, we implement this using base two. We group
124 * samples by their Most Significant Bit (MSB), extract the next M bit
125 * of them as an index within the group, and discard the rest of the
126 * bits.
127 *
128 * E.g., assume a sample 'x' whose MSB is bit n (starting from bit 0),
129 * and use M bit for indexing
130 *
131 * | n | M bits | bit (n-M-1) ... bit 0 |
132 *
133 * Because x is at least 2^n, and bit 0 to bit (n-M-1) is at most
134 * (2^(n-M) - 1), discarding bit 0 to (n-M-1) makes the round-off
135 * error
136 *
137 * 2^(n-M)-1 2^(n-M) 1
138 * e <= --------- <= ------- = ---
139 * 2^n 2^n 2^M
140 *
141 * Furthermore, we use "mean" of the range to represent the bucket,
142 * the error e can be lowered by half to 1 / 2^(M+1). By using M bits
143 * as the index, each group must contains 2^M buckets.
144 *
145 * E.g. Let M (FIO_IO_U_PLAT_BITS) be 6
146 * Error bound is 1/2^(6+1) = 0.0078125 (< 1%)
147 *
148 * Group MSB #discarded range of #buckets
149 * error_bits value
150 * ----------------------------------------------------------------
151 * 0* 0~5 0 [0,63] 64
152 * 1* 6 0 [64,127] 64
153 * 2 7 1 [128,255] 64
154 * 3 8 2 [256,511] 64
155 * 4 9 3 [512,1023] 64
156 * ... ... ... [...,...] ...
157 * 18 23 17 [8838608,+inf]** 64
158 *
159 * * Special cases: when n < (M-1) or when n == (M-1), in both cases,
160 * the value cannot be rounded off. Use all bits of the sample as
161 * index.
162 *
163 * ** If a sample's MSB is greater than 23, it will be counted as 23.
