Xorg ABI 15 support?

Tegra on Linux currently supports only ABI 14.
When will ABI 15 come to tegra3?

9 months later… I think the answer is clear…

L4T was in the R16.x days when Tegra 3 was actively developed, and is not actively updated these days. It would be painful, but it might be possible to port L4T R21.4 to Tegra 3 (I’d never attempt it…this would be a big undertaking). Individual suppliers of Tegra 3 embedded solutions would probably be the ones to ask about updating for ABI on that particular hardware.

If you are able to use Jetson/TegraK1/tegra124, which runs L4T R21.4, you’re in luck. This is in R21.4’s Xorg.0.log:

(II) Module ABI versions:
    X.Org ANSI C Emulation: 0.4
    X.Org Video Driver: 15.0
    X.Org XInput driver : 20.0
    X.Org Server Extension : 8.0
