- menuconfig CORESIGHT
- bool "CoreSight Tracing Support"
- select ARM_AMBA
- help
- This framework provides a kernel interface for the CoreSight debug
- and trace drivers to register themselves with. It's intended to build
- a topological view of the CoreSight components based on a DT
- specification and configure the right serie of components when a
- trace source gets enabled.
- if CORESIGHT
- config CORESIGHT_LINKS_AND_SINKS
- bool "CoreSight Link and Sink drivers"
- help
- This enables support for CoreSight link and sink drivers that are
- responsible for transporting and collecting the trace data
- respectively. Link and sinks are dynamically aggregated with a trace
- entity at run time to form a complete trace path.
- config CORESIGHT_LINK_AND_SINK_TMC
- bool "Coresight generic TMC driver"
- depends on CORESIGHT_LINKS_AND_SINKS
- help
- This enables support for the Trace Memory Controller driver.
- Depending on its configuration the device can act as a link (embedded
- trace router - ETR) or sink (embedded trace FIFO). The driver
- complies with the generic implementation of the component without
- special enhancement or added features.
- config CORESIGHT_SINK_TPIU
- bool "Coresight generic TPIU driver"
- depends on CORESIGHT_LINKS_AND_SINKS
- help
- This enables support for the Trace Port Interface Unit driver,
- responsible for bridging the gap between the on-chip coresight
- components and a trace for bridging the gap between the on-chip
- coresight components and a trace port collection engine, typically
- connected to an external host for use case capturing more traces than
- the on-board coresight memory can handle.
- config CORESIGHT_SINK_ETBV10
- bool "Coresight ETBv1.0 driver"
- depends on CORESIGHT_LINKS_AND_SINKS
- help
- This enables support for the Embedded Trace Buffer version 1.0 driver
- that complies with the generic implementation of the component without
- special enhancement or added features.
- config CORESIGHT_SOURCE_ETM3X
- bool "CoreSight Embedded Trace Macrocell 3.x driver"
- depends on !ARM64
- select CORESIGHT_LINKS_AND_SINKS
- help
- This driver provides support for processor ETM3.x and PTM1.x modules,
- which allows tracing the instructions that a processor is executing
- This is primarily useful for instruction level tracing. Depending
- the ETM version data tracing may also be available.
- config CORESIGHT_SOURCE_ETM4X
- bool "CoreSight Embedded Trace Macrocell 4.x driver"
- depends on ARM64
- select CORESIGHT_LINKS_AND_SINKS
- help
- This driver provides support for the ETM4.x tracer module, tracing the
- instructions that a processor is executing. This is primarily useful
- for instruction level tracing. Depending on the implemented version
- data tracing may also be available.
- config CORESIGHT_QCOM_REPLICATOR
- bool "Qualcomm CoreSight Replicator driver"
- depends on CORESIGHT_LINKS_AND_SINKS
- help
- This enables support for Qualcomm CoreSight link driver. The
- programmable ATB replicator sends the ATB trace stream from the
- ETB/ETF to the TPIUi and ETR.
