Mun, Gwan-gyeong Nov. 6, 2019, 9:26 p.m. UTC
The setting of MSA is done by the DDI .pre_enable() hook. And when we are
using MST, the MSA is only set to first mst stream by calling of
DDI .pre_eanble() hook. It raies issues to non-first mst streams.
Wrong MSA or missed MSA packets might show scrambled screen or wrong
screen.

This splits a setting of MSA to MST and SST cases. And In the MST case it
will call a setting of MSA after an allocating of Virtual Channel from
MST encoder pre_enable callback.

On Dell XPS without patch even booting with console (runlevel 3) screen black on second monitor after DP MST monitor.
Dell XPS  (KBL) > TypeC-to DP tp Dell 4K MST monitor and from that to DP monitor (Dell) and this last in the chain black.
But with patched kernel screen visible. 

GG, is issues seen in Shards real or can this be merged now?

This report was false positive result.
The result showed as

Starting subtest: modeset-vs-vblank-race
Subtest modeset-vs-vblank-race: SUCCESS (13.947s)


>    [2]:

The error message was 
(kms_flip:1114) INFO: Beginning modeset-vs-vblank-race on pipe C,
connector HDMI-A-2
(kms_flip:1114) CRITICAL: Failed assertion: end - start > 0.9 *
actual_frame_time(o) && end - start < 2.6 * actual_frame_time(o)

This patch is not related to HDMI connector case, it only affects DP
connecot (SST, MST).
There fore this error is not related the patch.
