8 | help |
| 9 | This framework provides a kernel interface for the CoreSight debug | |
| 10 | and trace drivers to register themselves with. It's intended to build | |
| 11 | a topological view of the CoreSight components based on a DT | |
| b9884d3b | 12 | specification and configure the right series of components when a |
| 3288731e MP |
13 | trace source gets enabled. |

| 18 | help | |
| 19 | This enables support for CoreSight link and sink drivers that are | |
| 20 | responsible for transporting and collecting the trace data | |
| 21 | respectively. Link and sinks are dynamically aggregated with a trace | |
| 22 | entity at run time to form a complete trace path. | |

| 28 | This enables support for the Trace Memory Controller driver. | |
| 29 | Depending on its configuration the device can act as a link (embedded | |
| 30 | trace router - ETR) or sink (embedded trace FIFO). The driver | |
| 31 | complies with the generic implementation of the component without | |
| 32 | special enhancement or added features. | |

| 38 | This enables support for the Trace Port Interface Unit driver, | |
| 39 | responsible for bridging the gap between the on-chip coresight | |
| 40 | components and a trace for bridging the gap between the on-chip | |
| 41 | coresight components and a trace port collection engine, typically | |
| 42 | connected to an external host for use case capturing more traces than | |
| 43 | the on-board coresight memory can handle. | |

| 58 | This driver provides support for processor ETM3.x and PTM1.x modules, | |
| 59 | which allows tracing the instructions that a processor is executing | |
| 60 | This is primarily useful for instruction level tracing. Depending | |
| 61 | the ETM version data tracing may also be available. | |
