Enabling the trace macrocell implies it has been configured properly and a sink has been identified for it. The path of coresight components linking the source to the sink is configured and managed automatically by the coresight framework. What: /sys/bus/coresight/devices/<memory_map>.stm/hwevent_enable Date: April 2016 KernelVersion: 4.7 Contact: Mathieu Poirier <mathieu.poirier@linaro.org> Description: (RW) Provides access to the HW event enable register, used in conjunction with HW event bank select register. What: /sys/bus/coresight/devices/<memory_map>.stm/hwevent_select Date: April 2016 KernelVersion: 4.7 Contact: Mathieu Poirier <mathieu.poirier@linaro.org> Description: (RW) Gives access to the HW event block select register (STMHEBSR) in order to configure up to 256 channels. Used in conjunction with "hwevent_enable" register as described above. What: /sys/bus/coresight/devices/<memory_map>.stm/port_enable Date: April 2016 KernelVersion: 4.7 Contact: Mathieu Poirier <mathieu.poirier@linaro.org> Description: (RW) Provides access to the stimulus port enable register (STMSPER). Used in conjunction with "port_select" described below. What: /sys/bus/coresight/devices/<memory_map>.stm/port_select Date: April 2016 KernelVersion: 4.7 Contact: Mathieu Poirier <mathieu.poirier@linaro.org> Description: (RW) Used to determine which bank of stimulus port bit in register STMSPER (see above) apply to. What: /sys/bus/coresight/devices/<memory_map>.stm/status Date: April 2016 KernelVersion: 4.7 Contact: Mathieu Poirier <mathieu.poirier@linaro.org> Description: (Read) List various control and status registers. The specific layout and content is driver specific. What: /sys/bus/coresight/devices/<memory_map>.stm/traceid Date: April 2016 KernelVersion: 4.7 Contact: Mathieu Poirier <mathieu.poirier@linaro.org> Description: (RW) Holds the trace ID that will appear in the trace stream coming from this trace entity. What: /sys/bus/coresight/devices/<memory_map>.stm/label Date: Aug 2025 KernelVersion 6.18 Contact: Mao Jinlong <quic_jinlmao@quicinc.com> Description: (Read) Show hardware context information of device. |
