and optionally a more detailed description.
* The enums section defines and documents the enumerated types referred to by
the histograms.
-* The fieldtrials section defines active field trials and their groups, along
- with their descriptions.
+* The histogram_suffixes section provides a compact way of defining histograms
+ by applying affixes to existing histograms. This could be done recursively
+ and the max recursion depth is 5. See the example below for details on how it
+ works.
-Each field trial lists the histograms that it affects. The complete list of
-histograms is computed by appending the field trial group names to each of
-the affected histograms. For example, define the following:
+Each histogram_suffixes tag lists the histograms that it affects. The complete
+list of histograms is computed by appending (or prepending - see blow) the
+histogram_suffixes suffix names to each of the affected histograms. For example,
+define the following:
<histogram name="FileLoadLatency"/>
- <fieldtrial name="SuperHttpExperiment">
- <group name="SuperHttpEnabled"/>
- <group name="SuperHttpDisabled"/>
+ <histogram_suffixes name="SuperHttpExperiment">
+ <suffix name="SuperHttpEnabled"/>
+ <suffix name="SuperHttpDisabled"/>
<affected-histogram name="FileLoadLatency"/>
- </fieldtrial>
+ </histogram_suffixes>
The complete list of histograms will be:
FileLoadLatency_SuperHttpEnabled
FileLoadLatency_SuperHttpDisabled
-Field trial definitions can currently be used in any situation where multiple
-suffixes need to be appended to a histogram name; they do not have to
-correspond to actual field trials in the Chrome source code.
+histogram_suffixes can also be used to insert affix in the middle. Example:
-TODO(mlloyd): Refactor the XML so that field trials can be distinguished from
-other types of suffix sets.
+ <histogram name="Prerender.Events"/>
+
+ <histogram_suffixes name="SuperHttpExperiment" ordering="prefix">
+ <suffix name="HoverStats50"/>
+ <affected-histogram name="Prerender.Events"/>
+ </histogram_suffixes>
+
+The complete list of histograms will be:
+
+ Prerender.Events
+ Prerender.HoverStats50_Events
+
+When 'ordering="prefix"' is present in the histogram_suffixes tag, the suffix
+will be inserted after the first dot separator of the affected-histogram name.
+Therefore, the affected-histogram name has to have at least one dot in it.

+ <summary>
+ Retries needed to enable a FET on tps65090 (AKA tpschrome). Tps65090 is a
+ power management unit (PMU) used on many ARM Chromebooks. Until version ES7
+ was rolled into production we would sometimes run into a problem where FET1
+ (the FET used to switch on and off the backlight) wouldn't turn on properly.
+ This problem was especially prevalent when the voltage was high (like when
+ the device was plugged into the wall). Retrying by turning the FET off and
+ on again is nearly always effective, so the kernel will retry up to 5 times
+ (currently) and will also log the fact that it needed to retry. On newest
+ kernels (kernel 3.8 and up) a kernel warning will be logged with WARN_ON if
+ the FET still failed to turn on after 5 tries. Refer to the kernel warning
+ reports to find that information. For more details about this bug refer to
+ http://crbug.com/338657 and http://crosbug.com/p/16009. Note that we log
+ retries on all 7 FETs even though we've only ever seen failures of FET1.
