DentOS Support for AS7712-32X

[abhiranjeet]

Hi,

I have been referring to https://github.com/opencomputeproject/OpenNetworkLinux.git for building ONL and now I have started with DentOS. To build it for AS7712-32X switch, I have added it under ONLPM_OPTION_PLATFORM_ALLOWLIST in setup.env file. Build was successful with a Debian 9 Installer.

Although, when installing the image on that switch, I am doing lsmod and don't see any platform modules loaded, even onlpdump is giving all sorts of error. Is this intended ?

DentOS only supports switches with switch ASCIs/silico supported by Linux’ switchdev driver. The AS7712-32X uses the switch silicon Broadcom BCM56960 Tomahawk 3.2 Tbps, requiring proprietary interfaces/Linux drivers. Therefore it is not supported by DentOS. Please contact Broadcom to provide switchdev drivers, and allow their devices to be used in modern infrastructures with need for security and flexibility.

Publishing the ASIC documentation to allow writing drivers would even be better.

Until Broadcom does that, the AS7712-32X can’t and won’t be supported by DentOS. Therefore, please close the issue.
