net: ethernet: mtk_eth_soc: use generic allocator for SRAM

2025-07-08T01:50:45+00:00

Use a dedicated "mmio-sram" node and the generic allocator instead of open-coding SRAM allocation for DMA rings. Keep support for legacy device trees but notify the user via a warning to update, and let the ethernet driver create the gen_pool in this case.

net: airoha: Move airoha_eth driver in a dedicated folder

2025-03-04T12:22:08+00:00

The airoha_eth driver has no codebase shared with mtk_eth_soc one. Moreover, the upcoming features (flowtable hw offloading, PCS, ..) will not reuse any code from MediaTek driver. Move the Airoha driver in a dedicated folder. Signed-off-by: Lorenzo Bianconi Signed-off-by: Paolo Abeni

net: airoha: Introduce ethernet support for EN7581 SoC

2024-07-14T14:46:53+00:00

Add airoha_eth driver in order to introduce ethernet support for Airoha EN7581 SoC available on EN7581 development board (en7581-evb). EN7581 mac controller is mainly composed by the Frame Engine (PSE+PPE) and QoS-DMA (QDMA) modules. FE is used for traffic offloading (just basic functionalities are currently supported) while QDMA is used for DMA operations and QOS functionalities between the mac layer and the external modules conncted to the FE GDM ports (e.g MT7530 DSA switch or external phys). A general overview of airoha_eth architecture is reported below: ┌───────┐ ┌───────┐ │ QDMA2 │ │ QDMA1 │ └───┬───┘ └───┬───┘ │ │ ┌───────▼─────────────────────────────────────────────▼────────┐ │ │ │ P5 P0 │ │ │ │ │ │ │ ┌──────┐ │ P3 ├────► GDM3 │ │ │ └──────┘ │ │ │ │ ┌─────┐ │ │ │ PPE ◄────┤ P4 PSE │ └─────┘ │ │ │ │ │ │ │ │ ┌──────┐ │ P9 ├────► GDM4 │ │ │ └──────┘ │ │ │ │ │ │ │ P2 P1 │ └─────────┬───────────────────────────────────────────┬────────┘ │ │ ┌───▼──┐ ┌──▼───┐ │ GDM2 │ │ GDM1 │ └──────┘ └──┬───┘ │ ┌────▼─────┐ │ MT7530 │ └──────────┘ Currently only hw LAN features (QDMA1+GDM1) are available while hw WAN (QDMA2+GDM{2,3,4}) ones will be added with subsequent patches introducing traffic offloading support.

net: ethernet: mtk_eth_soc: add support for Wireless Ethernet Dispatch (WED)

2022-04-06T13:08:49+00:00

The Wireless Ethernet Dispatch subsystem on the MT7622 SoC can be configured to intercept and handle access to the DMA queues and PCIe interrupts for a MT7615/MT7915 wireless card. It can manage the internal WDMA (Wireless DMA) controller, which allows ethernet packets to be passed from the packet switch engine (PSE) to the wireless card, bypassing the CPU entirely. This can be used to implement hardware flow offloading from ethernet to WLAN. Signed-off-by: Felix Fietkau Signed-off-by: David S. Miller
