drm/amd/display: Add one to EDID's audio channel count when passing to DC

2018-03-28T16:22:59+00:00

commit 731a373698c9675d5aed8a30d8c9861bea9c41a2 upstream.

DC takes channel count to mean the actual count. cea_sad's channels
represent it as number of channels - 1.

drm/amd/display: We shouldn't set format_default on plane as atomic driver

2018-03-28T16:22:59+00:00

commit 509648fcf0ce8650184649b43ad039f78dde155f upstream.

This is still a leftover from early atomic brinup days.

drm/amd/display: Default HDMI6G support to true. Log VBIOS table error.

2018-03-15T09:56:47+00:00

commit caf0a9030d75509f3cacefe466d6d69d26e3dee6 upstream.

There have been many reports of Ellesmere and Baffin systems not being
able to drive HDMI 4k60 due to the fact that we check the HDMI_6GB_EN
bit from VBIOS table. Windows seems to not have this issue.

On some systems we fail to the encoder cap info from VBIOS. In that case
we should default to enabling HDMI6G support.

drm/amd/display: check for ipp before calling cursor operations

2018-03-15T09:56:47+00:00

commit d6b6669762898dfc99e9273b8d8603bc47014aa9 upstream.

Currently all cursor related functions are made to all
pipes that are attached to a particular stream.
This is not applicable to pipes that do not have cursor plane
initialised like underlay.
Hence this patch allows cursor related operations on a pipe
only if ipp in available on that particular pipe.

The check is added to set_cursor_position & set_cursor_attribute.

drm/amd/display: Fix rehook MST display not light back on

2017-12-15T22:32:42+00:00

Original applied dm_restore_drm_connector_state() has got removed.
Set link status to BAD before hotplug() event could trigger
another modeset from userspace.

The fix "Fix MST daisy chain SST not light up" commit makes so it is trying
to create a stream prior to dc_sink. That makes dc_sink is not present in
create_stream_for_sink().
