Enabling this feature on supported GPUs will let the driver powering

Select this option to use secondary set of performance counters. Kernel

This will add a 3s timeout to all sync fence waits in the Mali

driver, so that when work for Mali has been waiting on a sync fence

for a long time a debug message will be printed, detailing what fence
|

is causing the block, and which dependent Mali atoms are blocked as a

result of this.

device attribute, where the timeout is specified in milliseconds.
