drm/amd/display: Allow truncation to 10 bits

2018-03-21T05:22:08+00:00

The truncation isn't being programmed if the truncation
depth is set to 2, it causes an issue with dce11.2 asic
using 6bit eDP panel. It required to truncate 12:10 in order to
perform spatial dither 10:6.

This change will allow 12:10 truncation to be enabled.

drm/amd/display: validate plane format on primary plane

2018-03-07T21:31:19+00:00

In dce110, the plane configuration is such that plane 0
or the primary plane should be rendered with only RGB data.

This patch adds the validation to ensure that no video data
is rendered on plane 0.

drm/amd/display: Fix takover from VGA mode

2018-03-07T21:28:32+00:00

HW Engineer's Notes:
 During switch from vga->extended, if we set the VGA_TEST_ENABLE and then
 hit the VGA_TEST_RENDER_START, then the DCHUBP timing gets updated correctly.
 Then vBIOS will have it poll for the VGA_TEST_RENDER_DONE and unset
 VGA_TEST_ENABLE, to leave it in the same state as before.

drm/amd/display: update infoframe after dig fe is turned on

2018-03-07T21:27:57+00:00

Before dig fe is enabled, infoframe can't be programmed. So in
suspend resume case our infoframe programmming was not going through.

This change changes the sequence so that infoframe is programmed
after.

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.
