Author: Christian Gmeiner <[email protected]> Date: Mon Oct 23 09:53:39 2023 +0200 etnaviv: Skip 'empty' cmd streams Make use of etna_cmd_stream_mark_end_of_context_init(..) to mark the end of context init states. If the cmd stream is untouched until etna_cmd_stream_flush(..) gets called the drm layer will downgrade this specific cmd stream to a noop. This safes us from calling into the kernel with an 'empty' cmd stream.
