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 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 providing a high performance switching solution for Enterprise Data Centers (EDC) for building Ethernet based clusters, High-Performance Computing (HPC) and embedded environments. config MLXBF_TMFIFO tristate "Mellanox BlueField SoC TmFifo platform driver" depends on ARM64 depends on ACPI depends on VIRTIO_CONSOLE && VIRTIO_NET help Say y here to enable TmFifo support. The TmFifo driver provides platform driver support for the TmFifo which supports console and networking based on the virtio framework. config MLXBF_BOOTCTL tristate "Mellanox BlueField Firmware Boot Control driver" depends on ARM64 depends on ACPI depends on NET help The Mellanox BlueField firmware implements functionality to request swapping the primary and alternate eMMC boot partition, and to set up a watchdog that can undo that swap if the system does not boot up correctly. This driver provides sysfs access to the userspace tools, to be used in conjunction with the eMMC device driver to do necessary initial swap of the boot partition. config MLXBF_PMC tristate "Mellanox BlueField Performance Monitoring Counters driver" depends on ARM64 depends on HWMON depends on ACPI help Say y here to enable PMC support. The PMC driver provides access to performance monitoring counters within various blocks in the Mellanox BlueField SoC via a sysfs interface. config NVSW_SN2201 tristate "Nvidia SN2201 platform driver support" depends on HWMON && I2C depends on ACPI || COMPILE_TEST select REGMAP_I2C help This driver provides support for the Nvidia SN2201 platform. The SN2201 is a highly integrated for one rack unit system with L3 management switches. It has 48 x 1Gbps RJ45 + 4 x 100G QSFP28 ports in a compact 1RU form factor. The system also including a serial port (RS-232 interface), an OOB port (1G/100M MDI interface) and USB ports for management functions. The processor used on SN2201 is Intel Atom®Processor C Series, C3338R which is one of the Denverton product families. System equipped with Nvidia®Spectrum-1 32x100GbE Ethernet switch. endif # MELLANOX_PLATFORM
