d84ad2c0 - net: lan969x: add FDMA implementation

Mon, 13 Jan 2025 19:36:09 +0000

net: lan969x: add FDMA implementationThe lan969x switch device supports manual frame injection and extractionto and from the switch core, using a number of injection and extractionqueues. This technique is currently supported, but delivers poorperformance compared to Frame DMA (FDMA).This lan969x implementation of FDMA, hooks into the existing FDMA forSparx5, but requires its own RX and TX handling, as lan969x does notsupport the same native cache coherency that Sparx5 does. Effectively,this means that we are going to use the DMA mapping API for mapping andunmapping TX buffers. The RX loop will utilize the page pool API forefficient RX handling. Other than that, the implementation is largelythe same, and utilizes the FDMA library for DCB and DB handling.Some numbers:Manual injection/extraction (before this series):// iperf3 -c 1.0.1.1[ ID] Interval Transfer Bitrate[ 5] 0.00-10.02 sec 345 MBytes 289 Mbits/sec sender[ 5] 0.00-10.06 sec 345 MBytes 288 Mbits/sec receiverFDMA (after this series):// iperf3 -c 1.0.1.1[ ID] Interval Transfer Bitrate[ 5] 0.00-10.03 sec 1.10 GBytes 940 Mbits/sec sender[ 5] 0.00-10.07 sec 1.10 GBytes 936 Mbits/sec receiverReviewed-by: Steen Hegelund Signed-off-by: Daniel Machon Link: https://patch.msgid.link/20250113-sparx5-lan969x-switch-driver-5-v2-5-c468f02fd623@microchip.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ethernet/microchip/sparx5/Kconfig

b0e81817 - net: build all switchdev drivers as modules when the bridge is a module

Mon, 26 Jul 2021 14:25:36 +0000

net: build all switchdev drivers as modules when the bridge is a moduleCurrently, all drivers depend on the bool CONFIG_NET_SWITCHDEV, but onlythe drivers that call some sort of function exported by the bridge, likebr_vlan_enabled() or whatever, have an extra dependency on CONFIG_BRIDGE.Since the blamed commit, all switchdev drivers have a functionaldependency upon switchdev_bridge_port_{,un}offload(), which is a pair offunctions exported by the bridge module and not by the bridge-independentpart of CONFIG_NET_SWITCHDEV.Problems appear when we have:CONFIG_BRIDGE=mCONFIG_NET_SWITCHDEV=yCONFIG_TI_CPSW_SWITCHDEV=ybecause cpsw, am65_cpsw and sparx5 will then be built-in but they willcall a symbol exported by a loadable module. This is not possible andwill result in the following build error:drivers/net/ethernet/ti/cpsw_new.o: in function `cpsw_netdevice_event':drivers/net/ethernet/ti/cpsw_new.c:1520: undefined reference to `switchdev_bridge_port_offload'drivers/net/ethernet/ti/cpsw_new.c:1537: undefined reference to `switchdev_bridge_port_unoffload'As mentioned, the other switchdev drivers don't suffer from this becauseswitchdev_bridge_port_offload() is not the first symbol exported by thebridge that they are calling, so they already needed to deal with thisin the same way.Fixes: 2f5dc00f7a3e ("net: bridge: switchdev: let drivers inform which bridge ports are offloaded")Reported-by: Linux Kernel Functional Testing Signed-off-by: Vladimir Oltean Signed-off-by: David S.
