  * The reason for adding this additional layer, rather than simply using the latest HAL directly and

  * which clients can use when they need to distinguish between different underlying HAL versions,

+     * To calibrate this mode, follow these steps:

+     *    //frameworks/base/libs/hwui/tests/macrobench/how_to_run.txt
+     * 2) Run the macrobench as follows:

+     *    done
+     * 3) Determine a fixed set of device clocks such that the loop in (2) can
+     *    run for at least 10 minutes, starting from an idle device on a desk
+     *    at room temperature (roughly 22 Celsius), without hitting thermal
+     *    throttling.
+     * 4) After setting those clocks, set the system property
+     *    ro.power.fixed_performance_scale_factor to a value N, where N is the
+     *    number of times the loop from (2) runs during the 10 minute test
+     *    cycle. It is expected that in FIXED_PERFORMANCE mode, unless there is
+     *    thermal throttling, the loop will run N to N+1 times (inclusive).
+     *
+     * After calibrating this, while in FIXED_PERFORMANCE mode, the macrobench
