6505b680 - net: mscc: ocelot: add MAC Merge layer support for VSC9959

Thu, 19 Jan 2023 12:27:04 +0000

net: mscc: ocelot: add MAC Merge layer support for VSC9959Felix (VSC9959) has a DEV_GMII:MM_CONFIG block composed of 2 registers(ENABLE_CONFIG and VERIF_CONFIG). Because the MAC Merge statistics andpMAC statistics are already in the Ocelot switch lib even if just Felixsupports them, I'm adding support for the whole MAC Merge layer in thecommon Ocelot library too.There is an interrupt (shared with the PTP interrupt) which signalschanges to the MM verification state. This is done because thepreemptible traffic classes should be committed to hardware only oncethe verification procedure has declared the link partner of beingcapable of receiving preemptible frames.We implement ethtool getters and setters for the MAC Merge layer state.The "TX enabled" and "verify status" are taken from the IRQ handler,using a mutex to ensure serialized access.Signed-off-by: Vladimir Oltean Signed-off-by: David S.

753a026c - net: ocelot: add FDMA support

Thu, 09 Dec 2021 15:49:11 +0000

net: ocelot: add FDMA supportEthernet frames can be extracted or injected autonomously to or fromthe device’s DDR3/DDR3L memory and/or PCIe memory space. Linked listdata structures in memory are used for injecting or extracting Ethernetframes. The FDMA generates interrupts when frame extraction orinjection is done and when the linked lists need updating.The FDMA is shared between all the ethernet ports of the switch anduses a linked list of descriptors (DCB) to inject and extract packets.Before adding descriptors, the FDMA channels must be stopped. It wouldbe inefficient to do that each time a descriptor would be added so thechannels are restarted only once they stopped.Both channels uses ring-like structure to feed the DCBs to the FDMA.head and tail are never touched by hardware and are completely handledby the driver. On top of that, page recycling has been added and ismostly taken from gianfar driver.Reviewed-by: Vladimir Oltean Co-developed-by: Alexandre Belloni Signed-off-by: Alexandre Belloni Signed-off-by: Clément Léger Signed-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ethernet/mscc/Makefile

d8ea7ff3 - net: mscc: ocelot: Add support for MRP

Tue, 16 Feb 2021 21:42:03 +0000

net: mscc: ocelot: Add support for MRPAdd basic support for MRP. The HW will just trap all MRP frames on thering ports to CPU and allow the SW to process them. In this way it ispossible to for this node to behave both as MRM and MRC.Current limitations are:- it doesn't support Interconnect roles.- it supports only a single ring.- the HW should be able to do forwarding of MRP Test frames so the SW will not need to do this. So it would be able to have the role MRC without SW support.Signed-off-by: Horatiu Vultur Signed-off-by: David S. Miller List of files: /linux-6.15/drivers/net/ethernet/mscc/Makefile

a4ae997a - net: mscc: ocelot: initialize watermarks to sane defaults

Fri, 15 Jan 2021 02:11:19 +0000

net: mscc: ocelot: initialize watermarks to sane defaultsThis is meant to be a gentle introduction into the world of watermarkson ocelot. The code is placed in ocelot_devlink.c because it will beintegrated with devlink, even if it isn't right now.My first step was intended to be to replicate the default configurationof the congestion watermarks programatically, since they are now goingto be tuned by the user.But after studying and understanding through trial and error how theywork, I now believe that the configuration used out of reset does not dojustice to the word "reservation", since the sum of all reservationsexceeds the total amount of resources (otherwise said, all reservationscannot be fulfilled at the same time, which means that, contrary to thereference manual, they don't guarantee anything).As an example, here's a dump of the reservation watermarks for framebuffers, for port 0 (for brevity, the ports 1-6 were omitted, but theyhave the same configuration):BUF_Q_RSRV_I(port 0, prio 0) = max 3000 bytesBUF_Q_RSRV_I(port 0, prio 1) = max 3000 bytesBUF_Q_RSRV_I(port 0, prio 2) = max 3000 bytesBUF_Q_RSRV_I(port 0, prio 3) = max 3000 bytesBUF_Q_RSRV_I(port 0, prio 4) = max 3000 bytesBUF_Q_RSRV_I(port 0, prio 5) = max 3000 bytesBUF_Q_RSRV_I(port 0, prio 6) = max 3000 bytesBUF_Q_RSRV_I(port 0, prio 7) = max 3000 bytesOtherwise said, every port-tc has an ingress reservation of 3000 bytes,and there are 7 ports in VSC9959 Felix (6 user ports and 1 CPU port).Concentrating only on the ingress reservations, there are, in total,8 [traffic classes] x 7 [ports] x 3000 [bytes] = 168,000 bytes of memoryreserved on ingress.But, surprise, Felix only has 128 KB of packet buffer in total...A similar thing happens with Seville, which has a larger packet buffer,but also more ports, and the default configuration is also overcommitted.This patch disables the (apparently) bogus reservations and moves allresources to the shared area. This way, real reservations can be set upby the user, using devlink-sb.Signed-off-by: Vladimir Oltean Reviewed-by: Florian Fainelli Signed-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ethernet/mscc/Makefile

9c90eea3 - net: mscc: ocelot: move net_device related functions to ocelot_net.c

Sat, 20 Jun 2020 15:43:44 +0000

net: mscc: ocelot: move net_device related functions to ocelot_net.cThe ocelot hardware library shouldn't contain too much net_devicespecific code, since it is shared with DSA which abstracts thatstructure away. So much as much of this code as possible into themscc_ocelot driver and outside of the common library.We're making an exception for MDB and LAG code. That is not yet exportedto DSA, but when it will, most of the code that's already in ocelot.cwill remain there. So, there's no point in moving code to ocelot_net.cjust to move it back later.We could have moved all net_device code to ocelot_vsc7514.c directly,but let's operate under the assumption that if a new switchdev ocelotdriver gets added, it'll define its SoC-specific stuff in a newocelot_vsc*.c file and it'll reuse the rest of the code.Signed-off-by: Vladimir Oltean Signed-off-by: David S.

net: mscc: ocelot: move ocelot_regs.c into ocelot_vsc7514.cocelot_regs.c actually shouldn't be part of the common library. Itdescribes the register map of the VSC7514 switch. The way ocelotswitches work, they'll have highly optimized register maps, so anotherSoC will likely have the same registers but laid out completelydifferent in memory (so there's little room for reusing this structure).So move it to ocelot_vsc7514.c instead.Signed-off-by: Vladimir Oltean Signed-off-by: David S.

Currently, it handles offloadingbridging to the hardware. ocelot_io.c handles register accesses. This isunfortunately needed because the register layout is packed and then dependson the number of ports available on the switch. The register definitionfiles are automatically generated.ocelot_board handles the switch integration on the SoC and on the board.Frame injection and extraction to/from the CPU port is currently done usingregister accesses which is quite slow. DMA is possible but the port is notable to absorb the whole switch bandwidth.Signed-off-by: Alexandre Belloni Reviewed-by: Andrew Lunn Signed-off-by: David S.
