[wiki] Updating general OpenWrt support status for all targets

Continuing the discussion from Linksys MR8300 AC2200 Tri Band:

https://openwrt.org/docs/techref/targets/ipq40xx would be the place to document the general support status of the ipq40xx target.

I encourage everybody to look through the other target pages listed on https://openwrt.org/docs/techref/targets/start and update the general OpenWrt support status, or share otherwise helpful knowledge about a target.

  • Are there any functional restrictions which are inherent to the target, not a specific device?
    • e.g. bcm63xx -> DSL will not work
  • Is there anything else worth knowing about a target?

When talking about "currently", please always add a date, e.g. "currently (August 2021)...".
The "Current status" is true at the time of writing, but might not be true in 1 year.

Your contributions to the wiki are welcome! :slight_smile:


In general, ipq40xx works very well and is fully supported - with one caveat, VLANs. Basically IPQ40xx Switch Config "Strangeness" is still correct, you can use VLANs, but there are a couple of constraints around that (courtesy of the swconfig driver, which exposes two virtual ethernet interfaces to the system, while there is only a single physical one - with hardcoded VID mappings distinguishing between them). A DSA based driver (ipqess) is kind of under development, but it's going to be a long walk to get that functional, as the hardware is quite 'special' and un(der)documented.

Patches to the existing swconfig drivers exist and have been tried, with serious performance implications - so it's back to the 'strange' state we have, until the DSA driver solves the issue once and for all.

tl;dr, this target works great, unless you want multiple VLANs - you can still get the later working, but will need quite some head scratching to get it working the way you need it. This indeed affects the target as a whole, given that the switch (at least the parts responsible for these issues) is part of the SOC.


That's valuable information!
Would you be willing to update the ipq40xx page linked above?

I'm not quite sure when I'd get to that, probably the weekend at the earliest - so if anyone beats me to it…
