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_MDT_LOADER
61 tristate "Qualcomm On Chip Memory (OCMEM) driver"
65 The On Chip Memory (OCMEM) allocator allows various clients to
66 allocate memory from OCMEM based on performance, latency and power
67 requirements. This is typically used by the GPU, camera/video, and
68 audio components on some Snapdragon SoCs.
70 config QCOM_PDR_HELPERS
72 select QCOM_QMI_HELPERS
74 config QCOM_QMI_HELPERS
79 tristate "Qualcomm Remote Filesystem memory driver"
83 The Qualcomm remote filesystem memory driver is used for allocating
84 and exposing regions of shared memory with remote processors for the
85 purpose of exchanging sector-data between the remote filesystem
86 service and its clients.
88 Say y here if you intend to boot the modem remoteproc.
91 bool "Qualcomm RPM-Hardened (RPMH) Communication"
92 depends on ARCH_QCOM && ARM64 || COMPILE_TEST
94 Support for communication with the hardened-RPM blocks in
95 Qualcomm Technologies Inc (QTI) SoCs. RPMH communication uses an
96 internal bus to transmit state requests for shared resources. A set
97 of hardware components aggregate requests for these resources and
98 help apply the aggregated state on the resource.
101 tristate "Qualcomm RPMh Power domain driver"
102 depends on QCOM_RPMH && QCOM_COMMAND_DB
104 QCOM RPMh Power domain driver to support power-domains with
105 performance states. The driver communicates a performance state
106 value to RPMh which then translates it into corresponding voltage
107 for the voltage rail.
110 tristate "Qualcomm RPM Power domain driver"
111 depends on QCOM_SMD_RPM
113 QCOM RPM Power domain driver to support power-domains with
114 performance states. The driver communicates a performance state
115 value to RPM which then translates it into corresponding voltage
116 for the voltage rail.
119 tristate "Qualcomm Shared Memory Manager (SMEM)"
120 depends on ARCH_QCOM || COMPILE_TEST
121 depends on HWSPINLOCK
123 Say y here to enable support for the Qualcomm Shared Memory Manager.
124 The driver provides an interface to items in a heap shared among all
125 processors in a Qualcomm platform.
128 tristate "Qualcomm Resource Power Manager (RPM) over SMD"
129 depends on ARCH_QCOM || COMPILE_TEST
132 If you say yes to this option, support will be included for the
133 Resource Power Manager system found in the Qualcomm 8974 based
136 This is required to access many regulators, clocks and bus
137 frequencies controlled by the RPM on these devices.
139 Say M here if you want to include support for the Qualcomm RPM as a
140 module. This will build a module called "qcom-smd-rpm".
142 config QCOM_SMEM_STATE
146 tristate "Qualcomm Shared Memory Point to Point support"
149 select QCOM_SMEM_STATE
152 Say yes here to support the Qualcomm Shared Memory Point to Point
156 tristate "Qualcomm Shared Memory State Machine"
158 select QCOM_SMEM_STATE
161 Say yes here to support the Qualcomm Shared Memory State Machine.
162 The state machine is represented by bits in shared memory.
165 tristate "Qualcomm socinfo driver"
169 Say yes here to support the Qualcomm socinfo driver, providing
170 information about the SoC to user space.
172 config QCOM_WCNSS_CTRL
173 tristate "Qualcomm WCNSS control driver"
174 depends on ARCH_QCOM || COMPILE_TEST
177 Client driver for the WCNSS_CTRL SMD channel, used to download nv
178 firmware to a newly booted WCNSS chip.
181 tristate "Qualcomm APR Bus (Asynchronous Packet Router)"
182 depends on ARCH_QCOM || COMPILE_TEST
185 select QCOM_PDR_HELPERS
187 Enable APR IPC protocol support between
188 application processor and QDSP6. APR is
189 used by audio driver to configure QDSP6
190 ASM, ADM and AFE modules.
