Subject: nouveau: 3d textures are unsupported, limit 3d levels to 1
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5524af81365d51757ef68a8e62dbd426d0b07184;p=mesa.git

nouveau: 3d textures are unsupported, limit 3d levels to 1

Ideally there would be a swrast fallback, but the driver isn't ready for
that. This should avoid crashes if someone tries to use 3d textures
though.
