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 "Qualcomm Glink SSR driver"
41 depends on QCOM_RPROC_COMMON
43 Say y here to enable GLINK SSR support. The GLINK SSR driver
44 implements the SSR protocol for notifying the remote processor about
45 neighboring subsystems going up or down.
48 tristate "QCOM General Serial Bus Interface"
49 depends on ARCH_QCOM || COMPILE_TEST
52 Say y here to enable GSBI support. The GSBI provides control
53 functions for connecting the underlying serial UART, SPI, and I2C
54 devices to the output pins.
57 tristate "Qualcomm Technologies, Inc. LLCC driver"
58 depends on ARCH_QCOM || COMPILE_TEST
60 Qualcomm Technologies, Inc. platform specific
61 Last Level Cache Controller(LLCC) driver for platforms such as,
62 SDM845. This provides interfaces to clients that use the LLCC.
63 Say yes here to enable LLCC slice driver.
65 config QCOM_MDT_LOADER
70 tristate "Qualcomm On Chip Memory (OCMEM) driver"
74 The On Chip Memory (OCMEM) allocator allows various clients to
75 allocate memory from OCMEM based on performance, latency and power
76 requirements. This is typically used by the GPU, camera/video, and
77 audio components on some Snapdragon SoCs.
79 config QCOM_PDR_HELPERS
81 select QCOM_QMI_HELPERS
83 config QCOM_QMI_HELPERS
88 tristate "Qualcomm Remote Filesystem memory driver"
92 The Qualcomm remote filesystem memory driver is used for allocating
93 and exposing regions of shared memory with remote processors for the
94 purpose of exchanging sector-data between the remote filesystem
95 service and its clients.
97 Say y here if you intend to boot the modem remoteproc.
100 bool "Qualcomm RPM-Hardened (RPMH) Communication"
101 depends on ARCH_QCOM && ARM64 || COMPILE_TEST
103 Support for communication with the hardened-RPM blocks in
104 Qualcomm Technologies Inc (QTI) SoCs. RPMH communication uses an
105 internal bus to transmit state requests for shared resources. A set
106 of hardware components aggregate requests for these resources and
107 help apply the aggregated state on the resource.
110 tristate "Qualcomm RPMh Power domain driver"
111 depends on QCOM_RPMH && QCOM_COMMAND_DB
113 QCOM RPMh Power domain driver to support power-domains with
114 performance states. The driver communicates a performance state
115 value to RPMh which then translates it into corresponding voltage
116 for the voltage rail.
119 tristate "Qualcomm RPM Power domain driver"
120 depends on QCOM_SMD_RPM
122 QCOM RPM Power domain driver to support power-domains with
123 performance states. The driver communicates a performance state
124 value to RPM which then translates it into corresponding voltage
125 for the voltage rail.
128 tristate "Qualcomm Shared Memory Manager (SMEM)"
129 depends on ARCH_QCOM || COMPILE_TEST
130 depends on HWSPINLOCK
132 Say y here to enable support for the Qualcomm Shared Memory Manager.
133 The driver provides an interface to items in a heap shared among all
134 processors in a Qualcomm platform.
137 tristate "Qualcomm Resource Power Manager (RPM) over SMD"
138 depends on ARCH_QCOM || COMPILE_TEST
141 If you say yes to this option, support will be included for the
142 Resource Power Manager system found in the Qualcomm 8974 based
145 This is required to access many regulators, clocks and bus
146 frequencies controlled by the RPM on these devices.
148 Say M here if you want to include support for the Qualcomm RPM as a
149 module. This will build a module called "qcom-smd-rpm".
151 config QCOM_SMEM_STATE
155 tristate "Qualcomm Shared Memory Point to Point support"
158 select QCOM_SMEM_STATE
161 Say yes here to support the Qualcomm Shared Memory Point to Point
165 tristate "Qualcomm Shared Memory State Machine"
167 select QCOM_SMEM_STATE
170 Say yes here to support the Qualcomm Shared Memory State Machine.
171 The state machine is represented by bits in shared memory.
174 tristate "Qualcomm socinfo driver"
178 Say yes here to support the Qualcomm socinfo driver, providing
179 information about the SoC to user space.
181 config QCOM_WCNSS_CTRL
