Fri, 24 Jan 2025 17:26:19 +0000

mellanox: Relocate mlx-platform driverMove 'mlx-platform' driver 'x86' to 'mellanox' folder.Motivation to allow running it on systems with ARM architecture.Since drivers/platform/x86/mlx-platform.c is rellocated to folderdrivers/platform/x86/, remove "MELLANOX PLATFORM DRIVER" item.This driver will be located under "MELLANOX HARDWARE PLATFORM SUPPORT"item.Reviewed-by: Michael Shych Signed-off-by: Vadim Pasternak Link: https://lore.kernel.org/r/20250124172632.22437-2-vadimp@nvidia.comReviewed-by: Ilpo Järvinen Signed-off-by: Ilpo Järvinen List of files: /linux-6.15/drivers/platform/mellanox/Makefile

662f2482 - platform/mellanox: Add support for new SN2201 system

Sat, 30 Apr 2022 11:58:08 +0000

platform/mellanox: Add support for new SN2201 systemThe SN2201 is a highly integrated for one rack unit system withL3 management switches. It has 48 x 1Gbps RJ45 + 4 x 100G QSFP28ports in a compact 1RU form factor. The system also including aserial 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.Features:- 48 ports RJ45 support 10/100/1000M speed.- Support 4 QSFP28 ports with 10/25/40/50/100G.- A USB port is available on SN2201. This port is used for image and File Management purposes - backing up and restoring images and config files- Provides flow control mechanism to ensure zero packet loss. Uses backpressure for half-duplex operation and IEEE802.3x for full duplex operation.- Cut-through and Store-and-Forward free switching mechanism. By default the mode is cut-through.- Standard 1U chassis height.- 19" rack mountable.- Extensive system LED and per port LEDs.- Redundant power supply.- 2 x AC Power Supply (one PSU is default, second PSU is optional).Signed-off-by: Michael Shych Reviewed-by: Vadim Pasternak Link: https://lore.kernel.org/r/20220430115809.54565-3-michaelsh@nvidia.comSigned-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/mellanox/Makefile

62f9529b - platform/mellanox: mlxreg-lc: Add initial support for Nvidia line card devices

Sat, 02 Oct 2021 09:32:36 +0000

platform/mellanox: mlxreg-lc: Add initial support for Nvidia line card devicesProvide support for the Nvidia MSN4800-XX line cards for MSN4800Ethernet modular switch system, providing a high performance switchingsolution for Enterprise Data Centers (EDC) for building Ethernet basedclusters, High-Performance Computing (HPC) and embedded environments.Initial version provides support for line card type MSN4800-C16. Thistype of line card is equipped with:- Lattice CPLD device, used for system and ports control.- four Nvidia gearbox devices, used for port splitting.- FPGA device, used for gearboxes management.- 16x100G QSFP28 ports.- hotpswap controllers, voltage regulators, analog-to-digital convertors, nvram devices.- status LED.During initialization driver creates:- line card's I2C tree through "i2c-mux-mlxcpd" driver.- line card's LED objects through "leds-mlxreg" driver.- line card's CPLD register space input / output "hwmon" attributes for line control and monitoring through "mlxreg-io" driver. These attributes provide CPLD and FPAG versioning, control for upgradable components burning, NVRAM devices write protection, line card revision, line card power consuming, line card reset cause indication, etcetera.Lattice CPLD device and nvram devices are feeding from auxiliary powerdomain and accessible, when line card is powered off. These devicesare connected by line card driver probing routine, invoked after linecard security verification is done by hardware and event lc#n_verifiedis received for line card located in slot #n.Gearboxes, FPGA, hotpswap controllers, voltage regulators,analog-to-digital convertors are feeding from main power domain. Thesedevices are connected after power good event "lc#n_powered" is receivedfor line card located in slot #n.The driver 'mlxreg-lc' is driven by 'mlxreg-hotplug' driver followingrelevant "hotplug" events.Signed-off-by: Vadim Pasternak Reviewed-by: Michael Shych Link: https://lore.kernel.org/r/20211002093238.3771419-8-vadimp@nvidia.comSigned-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/mellanox/Makefile

Thu, 08 Oct 2020 12:37:17 +0000

platform/mellanox: mlxbf-pmc: Add Mellanox BlueField PMC driverThe performance modules in BlueField are present in several hardwareblocks and each block provides access to these stats either throughcounters that can be programmed to monitor supported events orthrough memory-mapped registers that hold the relevant information.The hardware blocks that include a performance module are: * Tile (block containing 2 cores and a shared L2 cache) * TRIO (PCIe root complex) * MSS (Memory Sub-system containing the Memory Controller and L3 cache) * GIC (Interrupt controller) * SMMU (System Memory Management Unit)The mlx_pmc driver provides access to all of these performance modulesthrough a hwmon sysfs interface.v2 --> v3Update copyright info.v1 --> v2Remove unused headers.Add comma to arrays where last line is not a termination.Use kstrtoint in place of sscanf.UUID manipulation follows drivers/platform/mellanox/mlxbf-bootctl.cSigned-off-by: Shravan Kumar Ramani Reviewed-by: Vadim Pasternak Reviewed-by: Jiri Pirko Link: https://lore.kernel.org/r/4e19a1e5bf4197ad27fc57981fd280eaebd23577.1602160468.git.shravankr@nvidia.comSigned-off-by: Hans de Goede List of files: /linux-6.15/drivers/platform/mellanox/Makefile

79e29cb8 - platform/mellanox: Add bootctl driver for Mellanox BlueField Soc

Mon, 07 Oct 2019 15:48:46 +0000

platform/mellanox: Add bootctl driver for Mellanox BlueField SocThis commit adds the bootctl platform driver for Mellanox BlueFieldSoc, which queries secure state and controls the eMMC boot partitionswapping by sending SMC calls to ATF running at EL3.Below are the sequences of typical use case. 1. User requests boot partition swapping, which could be on-demand or during boot-image upgrade via UEFI capsule; 2. This bootctl driver handles the request and sends SMC call to ATF. ATF programs register BREADCRUMB0 which has value preserved during warm reset. It also programs eMMC to swap the boot partition; 3. After software reset (rebooting), ATF BL1 (BootRom) checks register BREADCRUMB0 and enable watchdog if configured; 4. If booting fails, the watchdog timer will trigger rebooting. In such case, ATF Boot ROM will switch the boot partition back to the previous one. This is a robust feature and used to prevent failure during boot partition upgrade.Reviewed-by: Vadim Pasternak Signed-off-by: Liming Sun Signed-off-by: Andy Shevchenko List of files: /linux-6.15/drivers/platform/mellanox/Makefile
