4af2950c - net: dsa: realtek-smi: add rtl8365mb subdriver for RTL8365MB-VC

Mon, 18 Oct 2021 09:38:01 +0000

net: dsa: realtek-smi: add rtl8365mb subdriver for RTL8365MB-VCThis patch adds a realtek-smi subdriver for the RTL8365MB-VC 4+1 port10/100/1000M switch controller. The driver has been developed based on aGPL-licensed OS-agnostic Realtek vendor driver known as rtl8367c foundin the OpenWrt source tree.Despite the name, the RTL8365MB-VC has an entirely different registerlayout to the already-supported RTL8366RB ASIC. Notwithstanding this,the structure of the rtl8365mb subdriver is loosely based on the rtl8366rbsubdriver. Like the 'rb, it establishes its own irqchip to handlecascaded PHY link status interrupts.The RTL8365MB-VC switch is capable of offloading a large number offeatures from the software, but this patch introduces only the mostbasic DSA driver functionality. The ports always function as standaloneports, with bridging handled in software.One more thing. Realtek's nomenclature for switches makes it hard toknow exactly what other ASICs might be supported by this driver. Thevendor driver goes by the name rtl8367c, but as far as I can tell, nochip actually exists under this name. As such, the subdriver is namedrtl8365mb to emphasize the potentially limited support. But it is clearfrom the vendor sources that a number of other more advanced switchesshare a similar register layout, and further support should not be toohard to add given access to the relevant hardware. With this in mind,the subdriver has been written with as few assumptions about theparticular chip as is reasonable. But the RTL8365MB-VC is the onlyhardware I have available, so some further work is surely needed.Co-developed-by: Michael Rasmussen Signed-off-by: Michael Rasmussen Signed-off-by: Alvin Šipraga Reviewed-by: Vladimir Oltean Reviewed-by: Linus Walleij Reviewed-by: Florian Fainelli Tested-by: Arınç ÜNAL Signed-off-by: David S.

56051948 - net: dsa: ocelot: add driver for Felix switch family

Thu, 14 Nov 2019 15:03:30 +0000

net: dsa: ocelot: add driver for Felix switch familyThis supports an Ethernet switching core from Vitesse / Microsemi /Microchip (VSC9959) which is part of the Ocelot family (a brand name),and whose code name is Felix. The switch can be (and is) integrated ondifferent SoCs as a PCIe endpoint device.The functionality is provided by the core of the Ocelot switch driver(drivers/net/ethernet/mscc). In this regard, the current driver is aninstance of Microsemi's Ocelot core driver, with a DSA front-end. Itinherits its name from VSC9959's code name, to distinguish itself fromthe switchdev ocelot driver.The patch adds the logic for probing a PCI device and defines theregister map for the VSC9959 switch core, since it has some differencesin register addresses and bitfield mappings compared to the other Ocelotswitches (VSC7511, VSC7512, VSC7513, VSC7514).The Felix driver declares the register map as part of the "instancetable". Currently the VSC9959 inside NXP LS1028A is the only instance,but presumably it can support other switches in the Ocelot family, whenused in DSA mode (Linux running on the external CPU, and not on theembedded MIPS).In a few cases, some h/w operations have to be done differently onVSC9959 due to missing bitfields. This is the case for the switch corereset and init. Because for this operation Ocelot uses some bits thatare not present on Felix, the latter has to use a register from theglobal registers block (GCB) instead.Although it is a PCI driver, it relies on DT bindings for compatibilitywith DSA (CPU port link, PHY library). It does not have any customdevice tree bindings, since we would like to minimize its dependency ondevice tree though.Signed-off-by: Claudiu Manoil Signed-off-by: Vladimir Oltean Signed-off-by: David S.

d8652956 - net: dsa: realtek-smi: Add Realtek SMI driver

Sat, 14 Jul 2018 09:45:55 +0000

net: dsa: realtek-smi: Add Realtek SMI driverThis adds a driver core for the Realtek SMI chips and asubdriver for the RTL8366RB. I just added this chip simplybecause it is all I can test.The code is a massaged variant of the code that has beensitting out-of-tree in OpenWRT for years in the absence ofa proper switch subsystem. This creates a DSA driver for it.I have tried to credit the original authors whereverpossible.The main changes I've done from the OpenWRT code:- Added an IRQ chip inside the RTL8366RB switch to demux and handle the line state IRQs.- Distributed the phy handling out to the PHY driver.- Added some RTL8366RB code that was missing in the driver at the time, such as setting up "green ethernet" with a funny jam table and forcing MAC5 (the CPU port) into 1 GBit.- Select jam table and add the default jam table from the vendor driver, also for ASIC "version 0" if need be.- Do not store jam tables in the device tree, store them in the driver.- Pick in the "initvals" jam tables from OpenWRT's driver and make those get selected per compatible for the whole system. It's apparently about electrical settings for this system and whatnot, not really configuration from device tree.- Implemented LED control: beware of bugs because there are no LEDs on the device I am using!We do not implement custom DSA tags. This is explained ina comment in the driver as well: this "tagging protocol" isnot simply a few extra bytes tagged on to the ethernetframe as DSA is used to. Instead, enabling the CPU tagswill make the switch start talking Realtek RRCP internally.For example a simple ping will make this kind of packetsappear inside the switch:0000 ff ff ff ff ff ff bc ae c5 6b a8 3d 88 99 a2 000010 08 06 00 01 08 00 06 04 00 01 bc ae c5 6b a8 3d0020 a9 fe 01 01 00 00 00 00 00 00 a9 fe 01 02 00 000030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00As you can see a custom "8899" tagged packet using theprotocol 0xa2. Norm RRCP appears to always have thisprotocol set to 0x01 according to OpenRRCP. You can alsosee that this is not a ping packet at all, instead theswitch is starting to talk network management issueswith the CPU port.So for now custom "tagging" is disabled.This was tested on the D-Link DIR-685 with initramfs andOpenWRT userspaces and works fine on all the LAN ports(lan0 .. lan3).

b2441318 - License cleanup: add SPDX GPL-2.0 license identifier to files with no license

Wed, 01 Nov 2017 14:07:57 +0000

License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseMany source files in the tree are missing licensing information, whichmakes it harder for compliance tools to determine the correct license.By default all files without license information are under the defaultlicense of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'SPDX license identifier. The SPDX identifier is a legally bindingshorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart andPhilippe Ombredanne.How this work was done:Patches were generated and checked against linux-4.14-rc6 for a subset ofthe use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up caseswhere non-standard license headers were used, and references to licensehad to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied toa file was done in a spreadsheet of side by side results from of theoutput of two independent scanners (ScanCode & Windriver) producing SPDXtag:value files created by Philippe Ombredanne. Philippe prepared thebase worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 filesassessed. Kate Stewart did a file by file comparison of the scannerresults in the spreadsheet to determine which SPDX license identifier(s)to be applied to the file. She confirmed any determination that was notimmediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines).All documentation files were explicitly excluded.The following heuristics were used to determine which SPDX licenseidentifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time.In total, over 70 hours of logged manual review was done on thespreadsheet to determine the SPDX license identifiers to apply to thesource files by Kate, Philippe, Thomas and, in some cases, confirmationby lawyers working with the Linux Foundation.Kate also obtained a third independent scan of the 4.13 code base fromFOSSology, and compared selected files where the other two scannersdisagreed against that SPDX file, to see if there was new insights. TheWindriver scanner is based on an older version of FOSSology in part, sothey are related.Thomas did random spot checks in about 500 files from the spreadsheetsfor the uapi headers and agreed with SPDX license identifier in thefiles he inspected. For the non-uapi files Thomas did random spot checksin about 15000 files.In initial set of patches against 4.14-rc6, 3 files were found to havecopy/paste license identifier errors, and have been fixed to reflect thecorrect identifier.Additionally Philippe spent 10 hours this week doing a detailed manualinspection and review of the 12,461 patched files from the initial patchversion early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correctThis produced a worksheet with 20 files needing minor correction. Thisworksheet was then exported into 3 different .csv files for thedifferent types of files to be modified.These .csv files were then reviewed by Greg. Thomas wrote a script toparse the csv files and add the proper SPDX tag to the file, in theformat that the file expected. This script was further refined by Gregbased on the output to detect more types of files automatically and todistinguish between header and source .c files (which need differentcomment types.) Finally Greg ran the script using the .csv files togenerate the patches.Reviewed-by: Kate Stewart Reviewed-by: Philippe Ombredanne Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/net/dsa/Makefile
