Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

config RPMSG

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_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.

Implementation status: atlas-only.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
