When working with the primary node we have the following scenarios: > - handle to fd -> pass fd to other APIs - gbm, opencl, vdpau, etc > - handle to fd -> fd to handle - use it internally Yeah, but this would once more mean that we expose the same functionality on the primary node we do on the render node. And that is exactly what I want to prevent, because I think it is a very bad idea and will result in basically deprecating the render node. For the problem at hand it was sufficient to drop the DRM_AUTH flag from the driver IOCTLs and I don't see a reason why we should go further than this. Please just completely drop this whole approach, Christian. > > -Emil _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
