1config INTEL_TH 2 tristate "Intel(R) Trace Hub controller" 3 depends on HAS_DMA && HAS_IOMEM 4 help 5 Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that 6 produce, switch and output trace data from multiple hardware and 7 software sources over several types of trace output ports encoded 8 in System Trace Protocol (MIPI STPv2) and is intended to perform 9 full system debugging. 10 11 This option enables intel_th bus and common code used by TH 12 subdevices to interact with each other and hardware and for 13 platform glue layers to drive Intel TH devices. 14 15 Say Y here to enable Intel(R) Trace Hub controller support. 16 17if INTEL_TH 18 19config INTEL_TH_PCI 20 tristate "Intel(R) Trace Hub PCI controller" 21 depends on PCI 22 help 23 Intel(R) Trace Hub may exist as a PCI device. This option enables 24 support glue layer for PCI-based Intel TH. 25 26 Say Y here to enable PCI Intel TH support. 27 28config INTEL_TH_ACPI 29 tristate "Intel(R) Trace Hub ACPI controller" 30 depends on ACPI 31 help 32 Intel(R) Trace Hub may exist as an ACPI device. This option enables 33 support glue layer for ACPI-based Intel TH. This typically implies 34 'host debugger' mode, that is, the trace configuration and capture 35 is handled by an external debug host and corresponding controls will 36 not be available on the target. 37 38 Say Y here to enable ACPI Intel TH support. 39 40config INTEL_TH_GTH 41 tristate "Intel(R) Trace Hub Global Trace Hub" 42 help 43 Global Trace Hub (GTH) is the central component of the 44 Intel TH infrastructure and acts as a switch for source 45 and output devices. This driver is required for other 46 Intel TH subdevices to initialize. 47 48 Say Y here to enable GTH subdevice of Intel(R) Trace Hub. 49 50config INTEL_TH_STH 51 tristate "Intel(R) Trace Hub Software Trace Hub support" 52 depends on STM 53 help 54 Software Trace Hub (STH) enables trace data from software 55 trace sources to be sent out via Intel(R) Trace Hub.
