RPMSG always gets selected by whoever wants it
config RPMSG tristate
config RPMSG_CHAR tristate "RPMSG device interface" depends on RPMSG depends on NET help Say Y here to export rpmsg endpoints as device files, usually found in /dev. They make it possible for user-space programs to send and receive rpmsg packets.
config RPMSG_CTRL tristate "RPMSG control interface" depends on RPMSG && ( RPMSG_CHAR || RPMSG_CHAR=n ) help Say Y here to enable the support of the /dev/rpmsg_ctrlX API. This API allows user-space programs to create endpoints with specific service name, source and destination addresses.
config RPMSG_NS tristate "RPMSG name service announcement" depends on RPMSG help Say Y here to enable the support of the name service announcement channel that probes the associated RPMsg device on remote endpoint service announcement.
config RPMSG_MTK_SCP tristate "MediaTek SCP" depends on MTK_SCP select RPMSG help Say y here to enable support providing communication channels to remote processors in MediaTek platforms. This use IPI and IPC to communicate with remote processors.
config RPMSG_QCOM_GLINK tristate select RPMSG
config RPMSG_QCOM_GLINK_RPM tristate "Qualcomm RPM Glink driver" select RPMSG_QCOM_GLINK depends on HAS_IOMEM depends on MAILBOX help Say y here to enable support for the GLINK RPM communication driver, which serves as a channel for communication with the RPM in GLINK enabled systems.
config RPMSG_QCOM_GLINK_SMEM tristate "Qualcomm SMEM Glink driver" select RPMSG_QCOM_GLINK depends on MAILBOX depends on QCOM_SMEM help Say y here to enable support for the GLINK SMEM communication driver, which provides support for using the GLINK communication protocol over SMEM.
config RPMSG_QCOM_SMD tristate "Qualcomm Shared Memory Driver (SMD)" depends on MAILBOX depends on QCOM_SMEM select RPMSG help Say y here to enable support for the Qualcomm Shared Memory Driver providing communication channels to remote processors in Qualcomm platforms.
config RPMSG_VIRTIO tristate "Virtio RPMSG bus driver" depends on HAS_DMA select RPMSG select RPMSG_NS select VIRTIO
config HAVE_IMX_RPMSG bool "IMX RPMSG driver on the AMP SOCs" default y depends on IMX_MBOX select RPMSG_VIRTIO help Say y here to enable support for the iMX Rpmsg Driver providing communication channels to remote processors in iMX asymmetric multiprocessing (AMP) platforms.
Especially, it is mandatory required when the partition reset is
required on some iMX AMP platforms.
config IMX_RPMSG_PINGPONG tristate "IMX RPMSG pingpong driver -- loadable modules only" default m depends on HAVE_IMX_RPMSG && m help One 32bit unsigned int data transactions demoe between the A core and the remote M core on the iMX AMP platforms.
Only the module mode is supported here, the demo would be kicked off
immediately when this module is insmoded.
config IMX_RPMSG_TTY tristate "IMX RPMSG tty driver -- loadable modules only" default m depends on HAVE_IMX_RPMSG && m help Demostrate the string transmission from A core to the remote M core on the iMX AMP platforms.
Only the module mode is supported here. The according device node
would be created after this module is insmoded. the demo would be
executed by the command "echo <string> > <accordingly node>", thus
remote M core would receive the string.
