config GSI

	bool "GSI support"

	help

	  This driver provides the transport needed to talk to the

	  IPA core. It replaces the BAM transport used previously.



	  The GSI connects to a peripheral component via uniform TLV

	  interface, and allows it to interface with other peripherals

	  and CPUs over various types of interfaces such as MHI, xDCI,

	  xHCI, GPI, WDI, Ethernet, etc.

	bool "GSI core Version 2 Registers SWI Support"

	depends on GSI

	help

	  GSI core registers Software interface version 2 has updated

	  registers interface to communicate with GSI. This includes

	  new registers offsets, new registers fields structure and

	  new registers.



config IPA3

	select GSI

	depends on NET

	help

	  This driver supports the Internet Packet Accelerator (IPA3) core.

	  IPA is a programmable protocol processor HW block.

	  It is designed to support generic HW processing of UL/DL IP packets

	  for various use cases independent of radio technology.

	  The driver support client connection and configuration

	  for the IPA core.

	  Kernel and user-space processes can call the IPA driver

	  to configure IPA core.



config IPA_WDI_UNIFIED_API

	bool "IPA WDI unified API support"

	depends on IPA3

	help

	  This driver supports IPA WDI unified API.

	  WDI is the interface between IPA micro controller and WLAN chipset.

	  It is designed to support IPA HW accelerating path for WLAN use case.

	  The IPA WDI unified API supports all WDI versions through a unified

	  interface.

	tristate "IPA3 RMNET WWAN Network Device"

	depends on IPA3 && QCOM_QMI_HELPERS

	help

	  This WWAN Network Driver implements network stack class device.

	  It supports Embedded data transfer from A7 to Q6. Configures IPA HW

	  for RmNet Data Driver and also exchange of QMI messages between

	  A7 and Q6 IPA-driver.



config ECM_IPA

	tristate "STD ECM LAN Driver support"

	depends on IPA3

	help

	  Enables LAN between applications processor and a tethered

	  host using the STD ECM protocol.

	  This Network interface is aimed to allow data path go through

	  IPA core while using STD ECM protocol.



config RNDIS_IPA

	tristate "RNDIS_IPA Network Interface Driver support"

	depends on IPA3

	help

	  Enables LAN between applications processor and a tethered

	  host using the RNDIS protocol.

	  This Network interface is aimed to allow data path go through

	  IPA core while using RNDIS protocol.



config IPA3_MHI_PROXY

	tristate "IPA3 MHI proxy driver"

	depends on RMNET_IPA3

	help

	  This driver is used as a proxy between modem and MHI host driver.

	  Its main functionality is to setup MHI Satellite channels on behalf of

	  modem and provide the ability of modem to MHI device communication.

	  Once the configuration is done modem will communicate directly with

	  the MHI device without AP involvement, with the exception of

	  power management.



config IPA_UT

	tristate "IPA Unit-Test Framework and Test Suites"

	depends on IPA3 && DEBUG_FS

	help

	  This Module implements IPA in-kernel test framework.

	  The framework supports defining and running tests, grouped

	  into suites according to the sub-unit of the IPA being tested.

	  The user interface to run and control the tests is debugfs file

	  system.



config IPA_EMULATION

	bool "IPA on X86 Linux (IPA emulation support)"

	depends on X86 && IPA3

	help

	  This options is used only when building the X86 version of

	  the IPA/GSI driver. On this mode, IPA driver will be probed

	  as PCIE device (and not platform device) where IPA emulation

	  shall be connected via PCIE to X86 machine.
