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 OCTEONTX2_MBOX
	tristate

config OCTEONTX2_AF
	tristate "Marvell OcteonTX2 RVU Admin Function driver"
	select OCTEONTX2_MBOX
	select NET_DEVLINK
	depends on (64BIT && COMPILE_TEST) || ARM64
	depends on PCI
	depends on PTP_1588_CLOCK_OPTIONAL
	help
	  This driver supports Marvell's OcteonTX2 Resource Virtualization
	  Unit's admin function manager which manages all RVU HW resources
	  and provides a medium to other PF/VFs to configure HW. Should be
	  enabled for other RVU device drivers to work.

config NDC_DIS_DYNAMIC_CACHING
	bool "Disable caching of dynamic entries in NDC"
	depends on OCTEONTX2_AF
	default n
	help
	  This config option disables caching of dynamic entries such as NIX SQEs
	  , NPA stack pages etc in NDC. Also locks down NIX SQ/CQ/RQ/RSS and
	  NPA Aura/Pool contexts.

config OCTEONTX2_PF
	tristate "Marvell OcteonTX2 NIC Physical Function driver"
	select OCTEONTX2_MBOX
	select NET_DEVLINK
	select PAGE_POOL
	select CRYPTO_LIB_AES if MACSEC
	depends on (64BIT && COMPILE_TEST) || ARM64
	select DIMLIB
	depends on PCI
	depends on PTP_1588_CLOCK_OPTIONAL
	depends on MACSEC || !MACSEC
	help
	  This driver supports Marvell's OcteonTX2 NIC physical function.

config OCTEONTX2_VF
	tristate "Marvell OcteonTX2 NIC Virtual Function driver"
	depends on OCTEONTX2_PF
	help
	  This driver supports Marvell's OcteonTX2 NIC virtual function.

config RVU_ESWITCH
	tristate "Marvell RVU E-Switch support"
	depends on OCTEONTX2_PF
	default m
	help
	  This driver supports Marvell's RVU E-Switch that
	  provides internal SRIOV packet steering and switching.

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.
