2019-05-31drm/amd/display: fix crash on setmode when mode is close to bw limitSu Sung Chung
[why] during It's possible to call dcn_validate_bandwidth with no plane. In that case, as we are only intersted in if output timing is supported or not, even if we cannot support native resolution, we still want to support lower resolution if it is valid [how] if there exist no surface, make viewport/rec_out size at max 1080p. It is already known that 1080p x 6(max # of pipes) is supported, so if we fail validation, it is because of the stream Signed-off-by: Su Sung Chung <Su.Chung@amd.com> Reviewed-by: Dmytro Laktyushkin <Dmytro.Laktyushkin@amd.com> Acked-by: Leo Li <sunpeng.li@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

[why] by adding fast_validate flag, we are skipping some portion of dcn_validate_bandwidth code that is not necessary for mode validation.

2019-01-14drm/amd/display: remove sink reference in dc_stream_stateJun Lei
[why] dc_stream_state containing a pointer to sink is poor design. Sink describes the display, and the specifications or capabilities it has. That information is irrelevant for dc_stream_state, which describes hardware state, and is generally used for hardware programming. It could further be argued that dc_sink itself is just a convenience dc provides, and DC should be perfectly capable of programming hardware without any dc_sinks (for example, emulated sinks). [how] Phase 1: Deprecate use of dc_sink pointer in dc_stream. Most references are trivial to remove, but some call sites are risky (such as is_timing_changed) with no obvious logical replacement. These will be removed in follow up change. Add dc_link pointer to dc_stream. This is the typical reason DC really needed sink pointer, and most call sites are replaced with this. DMs also need minor updates, as all 3 DMs leverage stream->sink for some functionality. this is replaced instead by a pointer to private data inside dc_stream_state, which is used by DMs as a quality of life improvment for some key functionality. it allows DMs to set pointers have to their own objects which associate OS objects to dc_stream_states (such as DisplayTarget and amdgpu_dm_connector). Without the private pointer, DMs would be forced to perform a lookup for callbacks.
