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 Core Power Reduction (CPR) support"
31 depends on ARCH_QCOM && HAS_IOMEM
35 Say Y here to enable support for the CPR hardware found on Qualcomm
38 This driver populates CPU OPPs tables and makes adjustments to the
39 tables based on feedback from the CPR hardware. If you want to do
40 CPUfrequency scaling say Y here.
42 To compile this driver as a module, choose M here: the module will
46 tristate "QCOM GENI Serial Engine Driver"
47 depends on ARCH_QCOM || COMPILE_TEST
49 This driver is used to manage Generic Interface (GENI) firmware based
50 Qualcomm Technologies, Inc. Universal Peripheral (QUP) Wrapper. This
51 driver is also used to manage the common aspects of multiple Serial
52 Engines present in the QUP.
55 tristate "QCOM General Serial Bus Interface"
56 depends on ARCH_QCOM || COMPILE_TEST
59 Say y here to enable GSBI support. The GSBI provides control
60 functions for connecting the underlying serial UART, SPI, and I2C
61 devices to the output pins.
64 tristate "Qualcomm Technologies, Inc. LLCC driver"
65 depends on ARCH_QCOM || COMPILE_TEST
68 Qualcomm Technologies, Inc. platform specific
69 Last Level Cache Controller(LLCC) driver for platforms such as,
70 SDM845. This provides interfaces to clients that use the LLCC.
71 Say yes here to enable LLCC slice driver.

75 depends on ARCH_QCOM && ARM64 || COMPILE_TEST
77 config QCOM_MDT_LOADER
82 tristate "Qualcomm On Chip Memory (OCMEM) driver"
86 The On Chip Memory (OCMEM) allocator allows various clients to
87 allocate memory from OCMEM based on performance, latency and power
88 requirements. This is typically used by the GPU, camera/video, and
89 audio components on some Snapdragon SoCs.
91 config QCOM_PDR_HELPERS
93 select QCOM_QMI_HELPERS
95 config QCOM_QMI_HELPERS
100 tristate "Qualcomm Remote Filesystem memory driver"
104 The Qualcomm remote filesystem memory driver is used for allocating
105 and exposing regions of shared memory with remote processors for the
106 purpose of exchanging sector-data between the remote filesystem
107 service and its clients.
109 Say y here if you intend to boot the modem remoteproc.
112 bool "Qualcomm RPM-Hardened (RPMH) Communication"
113 depends on ARCH_QCOM || COMPILE_TEST
115 Support for communication with the hardened-RPM blocks in
116 Qualcomm Technologies Inc (QTI) SoCs. RPMH communication uses an
117 internal bus to transmit state requests for shared resources. A set
118 of hardware components aggregate requests for these resources and
119 help apply the aggregated state on the resource.
122 tristate "Qualcomm RPMh Power domain driver"
123 depends on QCOM_RPMH && QCOM_COMMAND_DB
125 QCOM RPMh Power domain driver to support power-domains with
126 performance states. The driver communicates a performance state
127 value to RPMh which then translates it into corresponding voltage
128 for the voltage rail.
131 tristate "Qualcomm RPM Power domain driver"
133 depends on QCOM_SMD_RPM
135 QCOM RPM Power domain driver to support power-domains with
136 performance states. The driver communicates a performance state
137 value to RPM which then translates it into corresponding voltage
138 for the voltage rail.
141 tristate "Qualcomm Shared Memory Manager (SMEM)"
142 depends on ARCH_QCOM || COMPILE_TEST
143 depends on HWSPINLOCK
145 Say y here to enable support for the Qualcomm Shared Memory Manager.
146 The driver provides an interface to items in a heap shared among all
147 processors in a Qualcomm platform.

154 If you say yes to this option, support will be included for the
155 Resource Power Manager system found in the Qualcomm 8974 based
158 This is required to access many regulators, clocks and bus
159 frequencies controlled by the RPM on these devices.
161 Say M here if you want to include support for the Qualcomm RPM as a
162 module. This will build a module called "qcom-smd-rpm".
