Re: [Buildroot] [PATCH 1/1] package/mesa3d: don't disable DRI3 for some Gallium drivers

[Michael Taubert <info@arachnodroid.de>]

Hi Arnout,

I'm not that familiar with these configs, yet. But if I understand it 
right, your advice is to have the selection of these Gallium drivers 
should also select BR2_PACKAGE_MESA3D_DRI_DRIVER.

I will have a look on how to do that tomorrow and provide another patch 
then.

Kind regards,
Michael
