* EXECUTIVE SUMMARY
*
*
* 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.
+ * accurately will be 2^(GROUP_NR + PLAT_BITS - 1) nanoseconds.
*
* 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)
+ * be (FIO_IO_U_PLAT_GROUP_NR * 2^FIO_IO_U_PLAT_BITS) * sizeof(uint64_t)
* bytes.
*
* FIO_IO_U_PLAT_NR is the total number of buckets.
*
* DETAILS
*
- * Suppose the clat varies from 0 to 999 (usec), the straightforward
+ * Suppose the lat 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,
* 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
+ * a value 0 has a 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 {
* 3 8 2 [256,511] 64
* 4 9 3 [512,1023] 64
* ... ... ... [...,...] ...
- * 18 23 17 [8838608,+inf]** 64
+ * 28 33 27 [8589934592,+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.
+ * ** If a sample's MSB is greater than 33, it will be counted as 33.
