H A D | Kconfig | 192 tristate "Trace Buffer Extension (TRBE) driver" 195 This driver provides support for percpu Trace Buffer Extension (TRBE). 196 TRBE always needs to be used along with its corresponding percpu ETE 197 component. ETE generates trace data which is then captured with TRBE. 198 Unlike traditional sink devices, TRBE is a CPU feature accessible via 203 called coresight-trbe.
