2	tristate "Intel(R) Trace Hub controller"
3	help
4	  Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
5	  produce, switch and output trace data from multiple hardware and
6	  software sources over several types of trace output ports encoded
7	  in System Trace Protocol (MIPI STPv2) and is intended to perform
8	  full system debugging.

10	  This option enables intel_th bus and common code used by TH
11	  subdevices to interact with each other and hardware and for
12	  platform glue layers to drive Intel TH devices.
13
14	  Say Y here to enable Intel(R) Trace Hub controller support.

19	tristate "Intel(R) Trace Hub PCI controller"
20	depends on PCI
21	help
22	  Intel(R) Trace Hub may exist as a PCI device. This option enables
23	  support glue layer for PCI-based Intel TH.
24
25	  Say Y here to enable PCI Intel TH support.

27config INTEL_TH_GTH
28	tristate "Intel(R) Trace Hub Global Trace Hub"
29	help
30	  Global Trace Hub (GTH) is the central component of the
31	  Intel TH infrastructure and acts as a switch for source
32	  and output devices. This driver is required for other
33	  Intel TH subdevices to initialize.
34
35	  Say Y here to enable GTH subdevice of Intel(R) Trace Hub.
36
37config INTEL_TH_STH
38	tristate "Intel(R) Trace Hub Software Trace Hub support"
39	depends on STM
40	help
41	  Software Trace Hub (STH) enables trace data from software
42	  trace sources to be sent out via Intel(R) Trace Hub. It
43	  uses stm class device to interface with its sources.
44
45	  Say Y here to enable STH subdevice of Intel(R) Trace Hub.
46
47config INTEL_TH_MSU
48	tristate "Intel(R) Trace Hub Memory Storage Unit"
49	help
50	  Memory Storage Unit (MSU) trace output device enables
51	  storing STP traces to system memory. It supports single
52	  and multiblock modes of operation and provides read()
53	  and mmap() access to the collected data.
54
55	  Say Y here to enable MSU output device for Intel TH.
56
57config INTEL_TH_PTI
58	tristate "Intel(R) Trace Hub PTI output"
59	help
60	  Parallel Trace Interface unit (PTI) is a trace output device
61	  of Intel TH architecture that facilitates STP trace output via
62	  a PTI port.
63
64	  Say Y to enable PTI output of Intel TH data.
