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: 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: Default HDMI6G support to true. Log VBIOS table error.

2018-03-07T21:27:02+00:00

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.
