drm/amd/display: fix cursor related Pstate hang

2018-03-07T21:27:48+00:00

Move cursor programming to inside the OTG_MASTER_UPDATE_LOCK

If graphics plane go from 1 pipe to hsplit, the cursor updates
after mpc programming and unlock. Which means there is a window
of time where cursor is enabled on the wrong pipe if it's on
the right side of the screen (i.e. case where cursor need to
move from pipe 0 to pipe 3 post split). This will cause pstate hang.

Solution is to program the cursor while still locked.

drm/amd/display: Call update_stream_signal directly from amdgpu_dm

2018-03-07T21:27:34+00:00

There's no good place in DC to cover all place where stream signal should
be updated. update_stream_signal depends on timing which comes from DM.

drm/amd/display: Don't allow dual-link DVI on all ASICs.

2018-03-07T21:27:24+00:00

Our APUs (Carrizo, Stoney, Raven) don't support it.

v2: Don't use is_apu as other ASICs might also not support it

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

2018-02-28T20:14:41+00:00

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.

treewide/trivial: Remove ';;$' typo noise

On lkml suggestions were made to split up such trivial typo fixes into per subsystem
patches:

This patch is the result of the following script:

  $ sed -i 's/;;$/;/g' $(git grep -E ';;$'  | grep "\.[ch]:"  | grep -vwE 'for|ia64' | cut -d: -f1 | sort | uniq)

... followed by manual review to make sure it's all good.

Splitting this up is just crazy talk, let's get over with this and just do it.
