- * Aggregate clat samples to report percentile(s) of them.
- *
- * EXECUTIVE SUMMARY
- *
- * FIO_IO_U_PLAT_BITS determines the maximum statistical error on the
- * value of resulting percentiles. The error will be approximately
- * 1/2^(FIO_IO_U_PLAT_BITS+1) of the value.
- *
- * FIO_IO_U_PLAT_GROUP_NR and FIO_IO_U_PLAT_BITS determine the maximum
- * range being tracked for latency samples. The maximum value tracked
- * accurately will be 2^(GROUP_NR + PLAT_BITS -1) microseconds.
- *
- * FIO_IO_U_PLAT_GROUP_NR and FIO_IO_U_PLAT_BITS determine the memory
- * requirement of storing those aggregate counts. The memory used will
- * be (FIO_IO_U_PLAT_GROUP_NR * 2^FIO_IO_U_PLAT_BITS) * sizeof(int)
- * bytes.
- *
- * FIO_IO_U_PLAT_NR is the total number of buckets.
- *
- * DETAILS
- *
- * Suppose the clat varies from 0 to 999 (usec), the straightforward
- * method is to keep an array of (999 + 1) buckets, in which a counter
- * keeps the count of samples which fall in the bucket, e.g.,
- * {[0],[1],...,[999]}. However this consumes a huge amount of space,
- * and can be avoided if an approximation is acceptable.
- *
- * One such method is to let the range of the bucket to be greater
- * than one. This method has low accuracy when the value is small. For
- * example, let the buckets be {[0,99],[100,199],...,[900,999]}, and
- * the represented value of each bucket be the mean of the range. Then
- * a value 0 has an round-off error of 49.5. To improve on this, we
- * use buckets with non-uniform ranges, while bounding the error of
- * each bucket within a ratio of the sample value. A simple example
- * would be when error_bound = 0.005, buckets are {
- * {[0],[1],...,[99]}, {[100,101],[102,103],...,[198,199]},..,
- * {[900,909],[910,919]...} }. The total range is partitioned into
- * groups with different ranges, then buckets with uniform ranges. An
- * upper bound of the error is (range_of_bucket/2)/value_of_bucket
- *
- * For better efficiency, we implement this using base two. We group
- * samples by their Most Significant Bit (MSB), extract the next M bit
- * of them as an index within the group, and discard the rest of the
- * bits.
- *
- * E.g., assume a sample 'x' whose MSB is bit n (starting from bit 0),
- * and use M bit for indexing
- *
- * | n | M bits | bit (n-M-1) ... bit 0 |
- *
- * Because x is at least 2^n, and bit 0 to bit (n-M-1) is at most
- * (2^(n-M) - 1), discarding bit 0 to (n-M-1) makes the round-off
- * error
- *
- * 2^(n-M)-1 2^(n-M) 1
- * e <= --------- <= ------- = ---
- * 2^n 2^n 2^M
- *
- * Furthermore, we use "mean" of the range to represent the bucket,
- * the error e can be lowered by half to 1 / 2^(M+1). By using M bits
- * as the index, each group must contains 2^M buckets.
- *
- * E.g. Let M (FIO_IO_U_PLAT_BITS) be 6
- * Error bound is 1/2^(6+1) = 0.0078125 (< 1%)
- *
- * Group MSB #discarded range of #buckets
- * error_bits value
- * ----------------------------------------------------------------
- * 0* 0~5 0 [0,63] 64
- * 1* 6 0 [64,127] 64
- * 2 7 1 [128,255] 64
- * 3 8 2 [256,511] 64
- * 4 9 3 [512,1023] 64
- * ... ... ... [...,...] ...
- * 18 23 17 [8838608,+inf]** 64
- *
- * * Special cases: when n < (M-1) or when n == (M-1), in both cases,
- * the value cannot be rounded off. Use all bits of the sample as
- * index.
- *
- * ** If a sample's MSB is greater than 23, it will be counted as 23.
