The sets of registers for sysfs access 33 are defined per system type bases and include the registers related 34 to system resets operation, system reset causes monitoring and some 35 kinds of mux selection. 36 37config MLXREG_LC 38 tristate "Mellanox line card platform driver support" 39 depends on HWMON 40 depends on I2C 41 select REGMAP 42 help 43 This driver provides support for the Mellanox MSN4800-XX line cards, 44 which are the part of MSN4800 Ethernet modular switch systems 45 providing a high performance switching solution for Enterprise Data 46 Centers (EDC) for building Ethernet based clusters, High-Performance 47 Computing (HPC) and embedded environments. 48 49config MLXBF_TMFIFO 50 tristate "Mellanox BlueField SoC TmFifo platform driver" 51 depends on ARM64 52 depends on ACPI 53 depends on VIRTIO_CONSOLE && VIRTIO_NET 54 help 55 Say y here to enable TmFifo support. The TmFifo driver provides 56 platform driver support for the TmFifo which supports console 57 and networking based on the virtio framework. 58 59config MLXBF_BOOTCTL 60 tristate "Mellanox BlueField Firmware Boot Control driver" 61 depends on ARM64 62 depends on ACPI 63 help 64 The Mellanox BlueField firmware implements functionality to 65 request swapping the primary and alternate eMMC boot partition, 66 and to set up a watchdog that can undo that swap if the system 67 does not boot up correctly. This driver provides sysfs access 68 to the userspace tools, to be used in conjunction with the eMMC 69 device driver to do necessary initial swap of the boot partition. 70 71config MLXBF_PMC 72 tristate "Mellanox BlueField Performance Monitoring Counters driver" 73 depends on ARM64 74 depends on HWMON 75 depends on ACPI 76 help 77 Say y here to enable PMC support.
