Author: Thierry Reding <tred...@nvidia.com> Date: Wed Apr 4 16:04:25 2018 +0200 tegra: Treat resources with modifiers as scanout Resources created with modifiers are treated as scanout because there is no way for applications to specify the usage (though that capability may be useful to have in the future). Currently all the resources created by applications with modifiers are for scanout, so make sure they have bind flags set accordingly. This is necessary in order to properly export buffers for such resources so that they can be shared with scanout hardware.
