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 MLXBF_TMFIFO 38 tristate "Mellanox BlueField SoC TmFifo platform driver" 39 depends on ARM64 40 depends on ACPI 41 depends on VIRTIO_CONSOLE && VIRTIO_NET 42 help 43 Say y here to enable TmFifo support. The TmFifo driver provides 44 platform driver support for the TmFifo which supports console 45 and networking based on the virtio framework. 46 47config MLXBF_BOOTCTL 48 tristate "Mellanox BlueField Firmware Boot Control driver" 49 depends on ARM64 50 depends on ACPI 51 help 52 The Mellanox BlueField firmware implements functionality to 53 request swapping the primary and alternate eMMC boot partition, 54 and to set up a watchdog that can undo that swap if the system 55 does not boot up correctly. This driver provides sysfs access 56 to the userspace tools, to be used in conjunction with the eMMC 57 device driver to do necessary initial swap of the boot partition. 58 59config MLXBF_PMC 60 tristate "Mellanox BlueField Performance Monitoring Counters driver" 61 depends on ARM64 62 depends on HWMON 63 depends on ACPI 64 help 65 Say y here to enable PMC support. The PMC driver provides access 66 to performance monitoring counters within various blocks in the 67 Mellanox BlueField SoC via a sysfs interface. 68 69endif # MELLANOX_PLATFORM 70
