5 menu "Qualcomm SoC drivers"
8 tristate "Qualcomm AOSS Driver"
9 depends on ARCH_QCOM || COMPILE_TEST
11 depends on COMMON_CLK && PM
12 select PM_GENERIC_DOMAINS
14 This driver provides the means of communicating with and controlling
15 the low-power state for resources related to the remoteproc
16 subsystems as well as controlling the debug clocks exposed by the Always On
17 Subsystem (AOSS) using Qualcomm Messaging Protocol (QMP).
19 config QCOM_COMMAND_DB
20 bool "Qualcomm Command DB"
21 depends on ARCH_QCOM || COMPILE_TEST
22 depends on OF_RESERVED_MEM
24 Command DB queries shared memory by key string for shared system
25 resources. Platform drivers that require to set state of a shared
26 resource on a RPM-hardened platform must use this database to get
27 SoC specific identifier and information for the shared resources.
30 tristate "QCOM GENI Serial Engine Driver"
31 depends on ARCH_QCOM || COMPILE_TEST
33 This driver is used to manage Generic Interface (GENI) firmware based
34 Qualcomm Technologies, Inc. Universal Peripheral (QUP) Wrapper. This
35 driver is also used to manage the common aspects of multiple Serial
36 Engines present in the QUP.
39 tristate "QCOM General Serial Bus Interface"
40 depends on ARCH_QCOM || COMPILE_TEST
43 Say y here to enable GSBI support. The GSBI provides control
44 functions for connecting the underlying serial UART, SPI, and I2C
45 devices to the output pins.
48 tristate "Qualcomm Technologies, Inc. LLCC driver"
49 depends on ARCH_QCOM || COMPILE_TEST
51 Qualcomm Technologies, Inc. platform specific
52 Last Level Cache Controller(LLCC) driver for platforms such as,
53 SDM845. This provides interfaces to clients that use the LLCC.
54 Say yes here to enable LLCC slice driver.
56 config QCOM_KRYO_L2_ACCESSORS
58 depends on ARCH_QCOM && ARM64 || COMPILE_TEST
60 config QCOM_MDT_LOADER
65 tristate "Qualcomm On Chip Memory (OCMEM) driver"
69 The On Chip Memory (OCMEM) allocator allows various clients to
70 allocate memory from OCMEM based on performance, latency and power
71 requirements. This is typically used by the GPU, camera/video, and
72 audio components on some Snapdragon SoCs.
74 config QCOM_PDR_HELPERS
76 select QCOM_QMI_HELPERS
78 config QCOM_QMI_HELPERS
83 tristate "Qualcomm Remote Filesystem memory driver"
87 The Qualcomm remote filesystem memory driver is used for allocating
88 and exposing regions of shared memory with remote processors for the
89 purpose of exchanging sector-data between the remote filesystem
90 service and its clients.
92 Say y here if you intend to boot the modem remoteproc.
95 bool "Qualcomm RPM-Hardened (RPMH) Communication"
96 depends on ARCH_QCOM || COMPILE_TEST
98 Support for communication with the hardened-RPM blocks in
99 Qualcomm Technologies Inc (QTI) SoCs. RPMH communication uses an
100 internal bus to transmit state requests for shared resources. A set
101 of hardware components aggregate requests for these resources and
102 help apply the aggregated state on the resource.
105 tristate "Qualcomm RPMh Power domain driver"
106 depends on QCOM_RPMH && QCOM_COMMAND_DB
108 QCOM RPMh Power domain driver to support power-domains with
109 performance states. The driver communicates a performance state
110 value to RPMh which then translates it into corresponding voltage
111 for the voltage rail.
114 tristate "Qualcomm RPM Power domain driver"
115 depends on QCOM_SMD_RPM
117 QCOM RPM Power domain driver to support power-domains with
118 performance states. The driver communicates a performance state
119 value to RPM which then translates it into corresponding voltage
120 for the voltage rail.
123 tristate "Qualcomm Shared Memory Manager (SMEM)"
124 depends on ARCH_QCOM || COMPILE_TEST
125 depends on HWSPINLOCK
127 Say y here to enable support for the Qualcomm Shared Memory Manager.
128 The driver provides an interface to items in a heap shared among all
129 processors in a Qualcomm platform.
132 tristate "Qualcomm Resource Power Manager (RPM) over SMD"
133 depends on ARCH_QCOM || COMPILE_TEST
136 If you say yes to this option, support will be included for the
137 Resource Power Manager system found in the Qualcomm 8974 based
140 This is required to access many regulators, clocks and bus
141 frequencies controlled by the RPM on these devices.
143 Say M here if you want to include support for the Qualcomm RPM as a
144 module. This will build a module called "qcom-smd-rpm".
146 config QCOM_SMEM_STATE
150 tristate "Qualcomm Shared Memory Point to Point support"
153 select QCOM_SMEM_STATE
156 Say yes here to support the Qualcomm Shared Memory Point to Point
160 tristate "Qualcomm Shared Memory State Machine"
162 select QCOM_SMEM_STATE
165 Say yes here to support the Qualcomm Shared Memory State Machine.
166 The state machine is represented by bits in shared memory.
169 tristate "Qualcomm socinfo driver"
173 Say yes here to support the Qualcomm socinfo driver, providing
174 information about the SoC to user space.
176 config QCOM_WCNSS_CTRL
177 tristate "Qualcomm WCNSS control driver"
178 depends on ARCH_QCOM || COMPILE_TEST
181 Client driver for the WCNSS_CTRL SMD channel, used to download nv
182 firmware to a newly booted WCNSS chip.
185 tristate "Qualcomm APR Bus (Asynchronous Packet Router)"
186 depends on ARCH_QCOM || COMPILE_TEST
189 select QCOM_PDR_HELPERS
