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.

menuconfig MELLANOX_PLATFORM
bool "Platform support for Mellanox hardware"
depends on X86 || ARM || ARM64 || COMPILE_TEST
help
Say Y here to get to see options for platform support for
Mellanox systems. This option alone does not add any kernel code.
If you say N, all options in this submenu will be skipped and disabled.
if MELLANOX_PLATFORM
config MLX_PLATFORM
tristate "Mellanox Technologies platform support"
depends on ACPI && I2C && PCI
select REGMAP
help
This option enables system support for the Mellanox Technologies
platform. The Mellanox systems provide data center networking
solutions based on Virtual Protocol Interconnect (VPI) technology
enable seamless connectivity to 56/100Gb/s InfiniBand or 10/40/56GbE
connection.
If you have a Mellanox system, say Y or M here.
config MLXREG_DPU
tristate "Nvidia Data Processor Unit platform driver support"
depends on I2C
select REGMAP_I2C
help
This driver provides support for the Nvidia BF3 Data Processor Units,
which are the part of SN4280 Ethernet smart switch systems
providing a high performance switching solution for Enterprise Data
Centers (EDC) for building Ethernet based clusters, High-Performance
Computing (HPC) and embedded environments.
If you have a Nvidia smart switch system, say Y or M here.
config MLXREG_HOTPLUG
tristate "Mellanox platform hotplug driver support"
depends on HWMON
depends on I2C
select REGMAP
help
This driver handles hot-plug events for the power suppliers, power
cables and fans on the wide range Mellanox IB and Ethernet systems.
config MLXREG_IO
tristate "Mellanox platform register access driver support"
depends on HWMON
select REGMAP
help
This driver allows access to Mellanox programmable device register
space through sysfs interface. The sets of registers for sysfs access
are defined per system type bases and include the registers related
to system resets operation, system reset causes monitoring and some
kinds of mux selection.
config MLXREG_LC
tristate "Mellanox line card platform driver support"
depends on HWMON
depends on I2C
select REGMAP
help
This driver provides support for the Mellanox MSN4800-XX line cards,
which are the part of MSN4800 Ethernet modular switch systems
Annotation
- Atlas domain: Driver Families / drivers/platform.
- 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.
