config INTEL_TH tristate "Intel(R) Trace Hub controller" depends on HAS_DMA && HAS_IOMEM help Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that produce, switch and output trace data from multiple hardware and software sources over several types of trace output ports encoded in System Trace Protocol (MIPI STPv2) and is intended to perform full system debugging. This option enables intel_th bus and common code used by TH subdevices to interact with each other and hardware and for platform glue layers to drive Intel TH devices. Say Y here to enable Intel(R) Trace Hub controller support. if INTEL_TH config INTEL_TH_PCI tristate "Intel(R) Trace Hub PCI controller" depends on PCI help Intel(R) Trace Hub may exist as a PCI device. This option enables support glue layer for PCI-based Intel TH. Say Y here to enable PCI Intel TH support. config INTEL_TH_GTH tristate "Intel(R) Trace Hub Global Trace Hub" help Global Trace Hub (GTH) is the central component of the Intel TH infrastructure and acts as a switch for source and output devices. This driver is required for other Intel TH subdevices to initialize. Say Y here to enable GTH subdevice of Intel(R) Trace Hub. config INTEL_TH_STH tristate "Intel(R) Trace Hub Software Trace Hub support" depends on STM help Software Trace Hub (STH) enables trace data from software trace sources to be sent out via Intel(R) Trace Hub. It uses stm class device to interface with its sources. Say Y here to enable STH subdevice of Intel(R) Trace Hub. config INTEL_TH_MSU tristate "Intel(R) Trace Hub Memory Storage Unit" help Memory Storage Unit (MSU) trace output device enables storing STP traces to system memory. It supports single and multiblock modes of operation and provides read() and mmap() access to the collected data. Say Y here to enable MSU output device for Intel TH. config INTEL_TH_PTI tristate "Intel(R) Trace Hub PTI output" help Parallel Trace Interface unit (PTI) is a trace output device of Intel TH architecture that facilitates STP trace output via a PTI port. Say Y to enable PTI output of Intel TH data. config INTEL_TH_DEBUG bool "Intel(R) Trace Hub debugging" depends on DEBUG_FS help Say Y here to enable debugging. endif
