Hardware Timestamping Engine (HTE) Support.
|
|
|
|
Some devices provide a hardware timestamping engine which can
|
|
timestamp certain device lines/signals in realtime. It comes with a
|
|
benefit for the applications needing accurate timestamping event with
|
|
less jitter. This framework provides a generic interface to such HTE
|
|
providers and consumer devices.
|
|
|
|
If unsure, say no.

Enable this option for integrated hardware timestamping engine also

known as generic timestamping engine (GTE) support on NVIDIA Tegra194
|
|
systems-on-chip. The driver supports 352 LIC IRQs and 39 AON GPIOs
|
|
lines for timestamping in realtime.

The NVIDIA Tegra194 GTE test driver demonstrates how to use HTE
|
|
framework to timestamp GPIO and LIC IRQ lines.
