This driver provides support for percpu Trace Buffer Extension (TRBE).
- TRBE always needs to be used along with it's corresponding percpu ETE
+ TRBE always needs to be used along with its corresponding percpu ETE
component. ETE generates trace data which is then captured with TRBE.
Unlike traditional sink devices, TRBE is a CPU feature accessible via
- system registers. But it's explicit dependency with trace unit (ETE)
+ system registers. But its explicit dependency with trace unit (ETE)
requires it to be plugged in as a coresight sink device.
To compile this driver as a module, choose M here: the module will be
