The GLINK SSR driver implements the SSR protocol for notifying the remote processor about neighboring subsystems going up or down. config QCOM_GSBI tristate "QCOM General Serial Bus Interface" depends on ARCH_QCOM || COMPILE_TEST select MFD_SYSCON help Say y here to enable GSBI support. The GSBI provides control functions for connecting the underlying serial UART, SPI, and I2C devices to the output pins. config QCOM_LLCC tristate "Qualcomm Technologies, Inc. LLCC driver" depends on ARCH_QCOM || COMPILE_TEST help Qualcomm Technologies, Inc. platform specific Last Level Cache Controller(LLCC) driver for platforms such as, SDM845. This provides interfaces to clients that use the LLCC. Say yes here to enable LLCC slice driver. config QCOM_MDT_LOADER tristate select QCOM_SCM config QCOM_OCMEM tristate "Qualcomm On Chip Memory (OCMEM) driver" depends on ARCH_QCOM select QCOM_SCM help The On Chip Memory (OCMEM) allocator allows various clients to allocate memory from OCMEM based on performance, latency and power requirements. This is typically used by the GPU, camera/video, and audio components on some Snapdragon SoCs. config QCOM_PDR_HELPERS tristate select QCOM_QMI_HELPERS config QCOM_PM bool "Qualcomm Power Management" depends on ARCH_QCOM && !ARM64 select ARM_CPU_SUSPEND select QCOM_SCM help QCOM Platform specific power driver to manage cores and L2 low power modes. It interface with various system drivers to put the cores in low power modes. config QCOM_QMI_HELPERS tristate depends on NET config QCOM_RMTFS_MEM tristate "Qualcomm Remote Filesystem memory driver" depends on ARCH_QCOM select QCOM_SCM help The Qualcomm remote filesystem memory driver is used for allocating and exposing regions of shared memory with remote processors for the purpose of exchanging sector-data between the remote filesystem service and its clients. Say y here if you intend to boot the modem remoteproc. config QCOM_RPMH bool "Qualcomm RPM-Hardened (RPMH) Communication" depends on ARCH_QCOM && ARM64 || COMPILE_TEST help Support for communication with the hardened-RPM blocks in Qualcomm Technologies Inc (QTI) SoCs. RPMH communication uses an internal bus to transmit state requests for shared resources. A set of hardware components aggregate requests for these resources and help apply the aggregated state on the resource. config QCOM_RPMHPD bool "Qualcomm RPMh Power domain driver" depends on QCOM_RPMH && QCOM_COMMAND_DB help QCOM RPMh Power domain driver to support power-domains with performance states. The driver communicates a performance state value to RPMh which then translates it into corresponding voltage for the voltage rail. config QCOM_RPMPD bool "Qualcomm RPM Power domain driver" depends on QCOM_SMD_RPM=y help QCOM RPM Power domain driver to support power-domains with performance states. The driver communicates a performance state value to RPM which then translates it into corresponding voltage for the voltage rail. config QCOM_SMEM tristate "Qualcomm Shared Memory Manager (SMEM)" depends on ARCH_QCOM || COMPILE_TEST depends on HWSPINLOCK help Say y here to enable support for the Qualcomm Shared Memory Manager. The driver provides an interface to items in a heap shared among all processors in a Qualcomm platform. config QCOM_SMD_RPM tristate "Qualcomm Resource Power Manager (RPM) over SMD" depends on ARCH_QCOM || COMPILE_TEST depends on RPMSG help If you say yes to this option, support will be included for the Resource Power Manager system found in the Qualcomm 8974 based devices. This is required to access many regulators, clocks and bus frequencies controlled by the RPM on these devices. Say M here if you want to include support for the Qualcomm RPM as a module. This will build a module called "qcom-smd-rpm". config QCOM_SMEM_STATE bool config QCOM_SMP2P tristate "Qualcomm Shared Memory Point to Point support" depends on MAILBOX depends on QCOM_SMEM select QCOM_SMEM_STATE select IRQ_DOMAIN help Say yes here to support the Qualcomm Shared Memory Point to Point protocol. config QCOM_SMSM tristate "Qualcomm Shared Memory State Machine" depends on QCOM_SMEM select QCOM_SMEM_STATE select IRQ_DOMAIN help Say yes here to support the Qualcomm Shared Memory State Machine. The state machine is represented by bits in shared memory. config QCOM_SOCINFO tristate "Qualcomm socinfo driver" depends on QCOM_SMEM select SOC_BUS help Say yes here to support the Qualcomm socinfo driver, providing information about the SoC to user space. config QCOM_WCNSS_CTRL tristate "Qualcomm WCNSS control driver" depends on ARCH_QCOM || COMPILE_TEST depends on RPMSG help Client driver for the WCNSS_CTRL SMD channel, used to download nv firmware to a newly booted WCNSS chip. config QCOM_APR tristate "Qualcomm APR Bus (Asynchronous Packet Router)" depends on ARCH_QCOM || COMPILE_TEST depends on RPMSG select QCOM_PDR_HELPERS help Enable APR IPC protocol support between application processor and QDSP6. APR is used by audio driver to configure QDSP6 ASM, ADM and AFE modules. endmenu
