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
84 bool "Qualcomm Power Management"
85 depends on ARCH_QCOM && !ARM64
86 select ARM_CPU_SUSPEND
89 QCOM Platform specific power driver to manage cores and L2 low power
90 modes. It interface with various system drivers to put the cores in
93 config QCOM_QMI_HELPERS
98 tristate "Qualcomm Remote Filesystem memory driver"
102 The Qualcomm remote filesystem memory driver is used for allocating
103 and exposing regions of shared memory with remote processors for the
104 purpose of exchanging sector-data between the remote filesystem
105 service and its clients.
107 Say y here if you intend to boot the modem remoteproc.
110 bool "Qualcomm RPM-Hardened (RPMH) Communication"
111 depends on ARCH_QCOM && ARM64 || COMPILE_TEST
113 Support for communication with the hardened-RPM blocks in
114 Qualcomm Technologies Inc (QTI) SoCs. RPMH communication uses an
115 internal bus to transmit state requests for shared resources. A set
116 of hardware components aggregate requests for these resources and
117 help apply the aggregated state on the resource.
120 bool "Qualcomm RPMh Power domain driver"
121 depends on QCOM_RPMH && QCOM_COMMAND_DB
123 QCOM RPMh Power domain driver to support power-domains with
124 performance states. The driver communicates a performance state
125 value to RPMh which then translates it into corresponding voltage
126 for the voltage rail.
129 bool "Qualcomm RPM Power domain driver"
130 depends on QCOM_SMD_RPM=y
132 QCOM RPM Power domain driver to support power-domains with
133 performance states. The driver communicates a performance state
134 value to RPM which then translates it into corresponding voltage
135 for the voltage rail.
138 tristate "Qualcomm Shared Memory Manager (SMEM)"
139 depends on ARCH_QCOM || COMPILE_TEST
140 depends on HWSPINLOCK
142 Say y here to enable support for the Qualcomm Shared Memory Manager.
143 The driver provides an interface to items in a heap shared among all
144 processors in a Qualcomm platform.
147 tristate "Qualcomm Resource Power Manager (RPM) over SMD"
148 depends on ARCH_QCOM || COMPILE_TEST
151 If you say yes to this option, support will be included for the
152 Resource Power Manager system found in the Qualcomm 8974 based
155 This is required to access many regulators, clocks and bus
156 frequencies controlled by the RPM on these devices.
158 Say M here if you want to include support for the Qualcomm RPM as a
159 module. This will build a module called "qcom-smd-rpm".
161 config QCOM_SMEM_STATE
165 tristate "Qualcomm Shared Memory Point to Point support"
168 select QCOM_SMEM_STATE
171 Say yes here to support the Qualcomm Shared Memory Point to Point
175 tristate "Qualcomm Shared Memory State Machine"
