2019-04-25coresight: etm4x: Add kernel configuration for CONTEXTIDMathieu Poirier1-0/+2
Set the proper bit in the configuration register when contextID tracing has been requested by user space. That way PE_CONTEXT elements are generated by the tracers when a process is installed on a CPU.

2017-08-28perf: cs-etm: Fix ETMv4 CONFIGR entry in perf.data fileMike Leach1-0/+5
The value passed into the perf.data file for the CONFIGR register in ETMv4 was incorrectly being set to the command line options/ETMv3 value. Adds bit definitions and function to remap this value to the correct ETMv4 CONFIGR bit values for all selected options.

2016-02-20coresight: introducing a global trace ID functionMathieu Poirier1-0/+12
TraceID values have to be unique for all tracers and consistent between drivers and user space. As such introducing a central function to be used whenever a traceID value is required. The patch also account for data traceIDs, which are usually I(N) + 1. Signed-off-by: Mathieu Poirier <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2016-02-20coresight: etm-perf: new PMU driver for ETM tracersMathieu Poirier1-0/+27
Perf is a well known and used tool for performance monitoring and much more. A such it is an ideal candidate for integration with coresight based HW tracing. This patch introduces a PMU that represent a coresight tracer to the Perf core.
