This option enables 34 support glue layer for ACPI-based Intel TH. This typically implies 35 'host debugger' mode, that is, the trace configuration and capture 36 is handled by an external debug host and corresponding controls will 37 not be available on the target. 38 39 Say Y here to enable ACPI Intel TH support. 40 41 config INTEL_TH_GTH 42 tristate "Intel(R) Trace Hub Global Trace Hub" 43 help 44 Global Trace Hub (GTH) is the central component of the 45 Intel TH infrastructure and acts as a switch for source 46 and output devices.
