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