Field Documentation

queueCount

uint32_t Dss_DispCurrentStatus::queueCount

Counter to keep track of how many requests are queued to the driver. Note: This counter will be reset at the time of driver create

dequeueCount

uint32_t Dss_DispCurrentStatus::dequeueCount

Counter to keep track of how many requests are dequeued from the driver. Note: This counter will be reset at the time of driver create

dispFrmCount

uint32_t Dss_DispCurrentStatus::dispFrmCount

Counter to keep track of how many frames are displayed. For interlaced display, this is half of the actual field display. Note: This counter will be reset at the time of display start

repeatFrmCount

uint32_t Dss_DispCurrentStatus::repeatFrmCount

Counter to keep track of how many frames are repeated when the application fails to queue buffer at the display rate. Note: This counter will be reset at the time of display start

underflowCount

uint32_t Dss_DispCurrentStatus::underflowCount

Counter to keep track of number of underflows Note: This counter will be reset at the time of driver create

safetyViolationCount

uint32_t Dss_DispCurrentStatus::safetyViolationCount

Counter to keep track of number of safety violations Note: This counter will be reset at the time of driver create
