1# SPDX-License-Identifier: GPL-2.0-only2config INTEL_TH3 tristate "Intel(R) Trace Hub controller"4 depends on HAS_DMA && HAS_IOMEM5 help6 Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that7 produce, switch and output trace data from multiple hardware and8 software sources over several types of trace output ports encoded9 in System Trace Protocol (MIPI STPv2) and is intended to perform10 full system debugging.11 12 This option enables intel_th bus and common code used by TH13 subdevices to interact with each other and hardware and for14 platform glue layers to drive Intel TH devices.15 16 Say Y here to enable Intel(R) Trace Hub controller support.17 18if INTEL_TH19 20config INTEL_TH_PCI21 tristate "Intel(R) Trace Hub PCI controller"22 depends on PCI23 help24 Intel(R) Trace Hub may exist as a PCI device. This option enables25 support glue layer for PCI-based Intel TH.26 27 Say Y here to enable PCI Intel TH support.28 29config INTEL_TH_ACPI30 tristate "Intel(R) Trace Hub ACPI controller"31 depends on ACPI32 help33 Intel(R) Trace Hub may exist as an ACPI device. This option enables34 support glue layer for ACPI-based Intel TH. This typically implies35 'host debugger' mode, that is, the trace configuration and capture36 is handled by an external debug host and corresponding controls will37 not be available on the target.38 39 Say Y here to enable ACPI Intel TH support.40 41config INTEL_TH_GTH42 tristate "Intel(R) Trace Hub Global Trace Hub"43 help44 Global Trace Hub (GTH) is the central component of the45 Intel TH infrastructure and acts as a switch for source46 and output devices. This driver is required for other47 Intel TH subdevices to initialize.48 49 Say Y here to enable GTH subdevice of Intel(R) Trace Hub.50 51config INTEL_TH_STH52 tristate "Intel(R) Trace Hub Software Trace Hub support"53 depends on STM54 help55 Software Trace Hub (STH) enables trace data from software56 trace sources to be sent out via Intel(R) Trace Hub.
