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 [31mCONFIG_INTEL_TH[0m config [31mCONFIG_INTEL_TH_PCI[0m tristate "Intel(R) Trace Hub PCI controller" depends on [31mCONFIG_PCI[0m help Intel(R) Trace Hub may exist as a [31mCONFIG_PCI[0m device. This option enables support glue layer for [31mCONFIG_PCI[0m-based Intel TH. Say Y here to enable [31mCONFIG_PCI[0m Intel TH support. config [31mCONFIG_INTEL_TH_ACPI[0m tristate "Intel(R) Trace Hub ACPI controller" depends on [31mCONFIG_ACPI[0m help Intel(R) Trace Hub may exist as an [31mCONFIG_ACPI[0m device. This option enables support glue layer for [31mCONFIG_ACPI[0m-based Intel TH. This typically implies 'host debugger' mode, that is, the trace configuration and capture is handled by an external debug host and corresponding controls will not be available on the target. Say Y here to enable [31mCONFIG_ACPI[0m Intel TH support. config [31mCONFIG_INTEL_TH_GTH[0m 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.
