They make it possible for user-space programs to send and receive rpmsg packets. config RPMSG_QCOM_GLINK_NATIVE tristate select RPMSG config RPMSG_QCOM_GLINK_RPM tristate "Qualcomm RPM Glink driver" select RPMSG_QCOM_GLINK_NATIVE 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_NATIVE 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 VIRTIO config RPMSG_VIRTIO_CHAR bool "Enable Virtio RPMSG char device driver support" default y depends on RPMSG_VIRTIO depends on RPMSG_CHAR help Say y here to enable to use RPMSG char device interface. 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 > ", thus remote M core would receive the string. endmenu
