when --enable-autotools is used the kmsro driver does not support etnaviv. so I think mesa3d should be compiled with the meson build system
just for info: this bug is related to the latest release candidate buildroot-2019.05-rc2
Hi, kmsro driver is currently only available for vc4 GPU since Buildroot (2019.05) currently use autotools build system. See [1]. As you noticed, building kmsro driver for etnaviv require to use the meson build system. There is an existing patch series in the patchwork doing so [2]. There is even a patch adding the support for kmsro driver for etnaviv [3]. It would be great if you can test this series and send a feedback (Tested-by). See [4] for further details. So this is not really a bug, this is a missing feature due to the late switching to meson build system in mesa3d package.

Hello thank you for the info. I have verified your patch and it is working well for my i.mx6 board. I still did not figure out how to send a feedback "(Tested-by)", but I will try to do it in next days thank you for your help
I don't know when this is resolved. but I tested buildroot-2019.11.1 and the Problem does not exist anymore. the kmsro can be built, since mesa build system is switched to meson
