Figure 5-4 Add counter to the Events to Collect list
The added events appears in the Events to Collect list under its category name.
Note
Use the Chart Configuration view to add statistics from counters in the Events to Collect list to
the Timeline view. Certain counters are added to a the Timeline view charts by default, but
others must be added manually.
5.2.2
Removing events
To remove events from the Events to Collect list, select them and press
Delete
. If you select a
category and press
Delete
, that category and all of the events it contains are removed from the
Events to Collect list.
5.2.3
Mali-specific events
If you build the gator driver with Mali support and connect to either a Mali-400 or Mali-T6xx
target, there are many additional options in the counter configuration dialog.
For information about the meaning of each of the Mali-specific counters and how to interpret
the profiling data please read the Mali GPU Application Optimization Guide, available on the
Mali developer site, http://www.malideveloper.com.
When choosing which Mali events to add to the Events to Collect list, consider the following:
•
The Mali-400 GPU contains two counters per block, each of which can count one of many
events. You can add either or both to the Events to Collect list. You can add any number
of the many available Mali-T6xx counters as the Mali-T6xx hardware reports its hardware
events through a block of shared memory rather than through dedicated hardware
registers.
•
Vertex and fragment processor counters are delivered as a single total at the end of each
phase of activity.
•
L2 counters report continuously because the cache is shared by the vertex and fragment
processors and cannot easily be attributed to a single operation.
