Linux support for Realtek switches

Realtek has developed multiple generations of networking SoCs. An SDK is provided by Realtek for managed switches built on these platforms, but of course we can do better by developing actual mainline Linux support. This wiki gathers documentation on the SoCs, the switches they are implemented in, and the drivers written to support these devices.

Development is performed (mostly) on commercially available switches:

• Models
• Owners and quirks
• Supported SoCs:
  • RTL83xx series overview
  • RTL93xx series overview

Specific parts of the hardware are documented on more detailed pages:

• PoE management
• RTL838x switch overview
• NIC interface
• SoC interrupts
• LED control
• SFP
• SerDes (Serializer-DeSerialiser)
• GPIO control
• Pad control
• JTAG debugging

• Current status
• Testing
• Image formats
• GPL source drops from switch vendors
• Register documentation: login with Github account, ask svanheule for access.

Interested in helping with the development, or looking for other ways to contribute? You can find us on #rtl83xx on libera.chat. Be sure to say hi and stick around for a while (we're not always very active).
