Hello Andreas Boll,

thanks for your quick followup.

Ok, right.

armhf would be the most revelant architecture right now.

Soon (if not already) arm64 will likely also be relevant
(as the etnaviv driver will grow more support for GC* variants
and very old information I have from etnaviv guys is that they
thought it would be relatively easy to support the variant
that was going to be shipped with imx8, which is arm64).

Could go either way on armel I guess, not sure anyone cares.

There might be practical issues like kernel config that might not
make it possible to enable it on arm64..... I don't know.
Maybe the kernel settings should be fixed rather than adhering to
it though (the etnaviv driver is enabled in the kernel because I
asked for it and someone volunteered to enable it in the config,
so we might just have to ask for it to be enabled on arm64).

I think so, yes.
