I’m not sure what device the s922x is used in but yes, it’s meant for an Android set top....then again that’s exactly what the RK3399 is designed for, hence the Mali gpu’s. Almost anything running a Mali GPU is meant for an Androidtv box or phone. What’s important is the ARM cores on the chip which if you look into it the 4xA73+2xA53 is one of the strongest consumer ARM soc arrangements out at the moment. I think it’s not difficult at this point for someone who knows what they’re doing to get a working kernel patched for the thing. I don’t think kernel 5.2 needed many if any hardware patched that would prevent an RT patch from applying clean-ish. I just get lost trying to fix the mismatches myself, and I hate dealing with ARM tool chains and compilers.
The one advantage of the rk3399 boards seems to be the number of PCIE lanes that were available to be broken out of the SOC. I’ve seen RK3399 boards with more different things attached to PCIE lanes than any other arm chip on the market. Looking into it, it looks like Khadas is using this chip now too on the vim3. That board has an M.2 slot so depending on the PCIE arrangement it could be adapted for a PCIE Mesa card possibly. I’d still rather use the N2 though, it’s built on top of a big aluminum heat sink, I’ve never even seen the thing get warm.
