CONFIG_CORESIGHT_TRBE: Trace Buffer Extension (TRBE) driver

General informations

The Linux kernel configuration item CONFIG_CORESIGHT_TRBE:

• prompt: Trace Buffer Extension (TRBE) driver
• type: tristate
• depends on: CONFIG_ARM64 && CONFIG_CORESIGHT_SOURCE_ETM4X
• defined in drivers/hwtracing/coresight/Kconfig
• found in Linux kernels: 5.13–5.19, 6.0–6.10
• modules built: coresight-trbe

Help text

This driver provides support for percpu Trace Buffer Extension (TRBE). 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 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 called coresight-trbe.
