	depends on ARCH_QCOM



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.



config GSI_REGISTER_VERSION_2

	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

	tristate "IPA3 support"

	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_DEBUG

	bool "IPA DEBUG for non-perf build"

	depends on IPA3

	help

	  This driver support more debug info for non-perf build.

	  If you use the non-perf build and want to have more debug

	  info enabled, then this flag can be enabled.

	  It is not suggested to enable this flag for perf build.



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.



config RMNET_IPA3

	tristate "IPA3 RMNET WWAN Network Device"

	depends on IPA3

	select 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 IPA3_MHI_PRIME_MANAGER

	tristate "IPA3_MHI Prime Manager driver"

	depends on IPA3

	help

	  This driver functionality is to setup MHI Prime channels between Host and

	  modem and enable the ability for MHI Prime communication.

	  Once the configuration is done modem will communicate directly with

	  the Host without AP involvement for tethering data offload.



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 MSM_11AD

	tristate "Platform driver for 11ad chip"

	depends on PCI

	depends on PCI_MSM

	default n

	help

	  This module adds required platform support for wireless adapter based on

	  Qualcomm Technologies, Inc. 11ad chip, integrated into MSM platform



	  If you choose to build it as a module, it will be called

	  msm_11ad_proxy.



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.



config USB_BAM

	bool "USB BAM Driver"

	depends on SPS && USB_GADGET

	help

	  Enabling this option adds USB BAM Driver.

	  USB BAM driver was added to supports Smart Peripheral Subsystem

	  Peripheral-to-Peripheral transfers between the USB and other

	  peripheral.



config QCOM_GENI_SE

	tristate "QCOM GENI Serial Engine Driver"

	help

	  This module is used to interact with GENI based Serial Engines on

	  Qualcomm Technologies, Inc. Universal Peripheral(QUPv3). This

	  module is used to configure and read the configuration from the

	  Serial Engines.



config IPA3_REGDUMP

	bool "Dump or collect IPA/GSI register values on Linux crash"

	depends on IPA3

	help

	  This option is to be used when the saving of IPA register state is

	  desired upon a fatal system exception. When an exception occurs,

	  an IPA register collection algorithm will be run in the context of

	  the exception handler.  A predefined set of registers will be read

	  and their values will be placed into a static hierarchical data

	  structure that can be perused post crash.



choice

	prompt "Platform whose registers are to be dumped/collected"

	depends on IPA3_REGDUMP

	help

	  The choices within represent the possible platforms this build is

	  intended for. The choices are mutually exclusive.  By selecting

	  one, you effect the inclusion path used, such that the relevant

	  register definitions will be found.  Each platform has unique

	  register definitions.



config IPA3_REGDUMP_IPA_4_5

	bool "The 4.5 IPA"

	depends on IPA3_REGDUMP

	depends on ARCH_KONA

	help

	  Set this to enable the 4.5 IPA's registers to be dumped/collected.



endchoice



config IPA3_REGDUMP_NUM_EXTRA_ENDP_REGS

	int "The number of extra endp registers for remaining pipes"

	depends on IPA3_REGDUMP

	default 0

	help

	  If the platform has extra endpoint registers for remaining

	  pipes, please express how many here.
