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/Makefile

010fe5df - net: lan969x: add RGMII implementation

Fri, 20 Dec 2024 13:48:47 +0000

net: lan969x: add RGMII implementationThe lan969x switch device includes two RGMII port interfaces (port 28and 29) supporting data speeds of 1 Gbps, 100 Mbps and 10 Mbps. MAClevel delays are configurable through the HSIO_WRAP target, by choosinga phase shift selector, corresponding to a certain time delay in nanoseconds.Add new file: lan969x_rgmii.c that contains the implementation forconfiguring the RGMII port devices. MAC level delays are configuredusing the "{rx,tx}-internal-delay-ps" properties. These properties mustbe specified independently of the phy-mode. If missing, or set to zero,the MAC will not apply any delay.Reviewed-by: Steen Hegelund Reviewed-by: Horatiu Vultur Tested-by: Robert Marko Signed-off-by: Daniel Machon Link: https://patch.msgid.link/20241220-sparx5-lan969x-switch-driver-4-v5-8-fa8ba5dff732@microchip.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ethernet/microchip/sparx5/Makefile

5ba3f846 - net: sparx5: add indirection layer to register macros

Fri, 04 Oct 2024 13:19:28 +0000

net: sparx5: add indirection layer to register macrosThe register macros are used to read and write to the switch registers.The registers are largely the same on Sparx5 and lan969x, however in somecases they differ. The differences can be one or more of the following:target size, register address, register count, group address, groupcount, group size, field position, field size.In order to handle these differences, we introduce a new indirectionlayer, that defines and maps them to corresponding values, based on theplatform. As the register macro arguments can now be non-constants, wealso add non-constant variants of FIELD_GET and FIELD_PREP.Since the indirection layer contributes to longer macros, we havechanged the formatting of them slightly, to adhere to a 80 characterlimit, and added a comment if a macro is platform-specific.With these additions, we can reuse all the existing macros forlan969x.Reviewed-by: Steen Hegelund Signed-off-by: Daniel Machon Signed-off-by: Paolo Abeni List of files: /linux-6.15/drivers/net/ethernet/microchip/sparx5/Makefile

net: sparx5: add port mirroring implementationThe hardware supports three independent mirroring probes. Each probe canbe configured to mirror rx or tx traffic (direction).Using tc matchall, it is now possible to add a source port and a monitorport to a mirror probe. Depending on the mirror direction, rx or txtraffic from a source port will be mirrored to the monitor port.A single source port can be a member of multiple mirror probes.Signed-off-by: Daniel Machon Reviewed-by: Steen Hegelund Signed-off-by: David S.
