H A D | dc_resource.c | 00737c59 Mon Oct 29 15:05:47 CDT 2018 Eric Bernstein <eric.bernstein@amd.com> drm/amd/display: get tail pipe before aquire free pipe
[Why] For some complicated blending transition cases, the head pipe of the second stream may end up being a higher pipe index than the free pipe. In those cases dc_add_plane_to_context will incorrectly set the tail_pipe to the free pipe, which will cause the top_pipe and bottom_pipe to be the same
[How] Move the call to resource_get_tail_pipe_for_stream() to be before call to acquire_free_pipe_for_stream().
