The QTI BWPROF Driver is responsible for monitoring bandwidth counters on
|
|
Qualcomm Technologies, Inc. (QTI) chipset that represent the read/write traffic
|
|
through different interconnects in the system. The driver provides this data to
|
|
userspace clients at modest time intervals for the purpose of bandwidth
