4.11 r3 drm-tip WITH Dirty Hack
No screen image on display. Just black with backlight. Fastboot=1 doesn't
working. Get fastboot to work by dirty hack:
[
In intel_display.c, I changed the line
FROM
if (i915.fastboot && intel_pipe_config_compare(dev,
to_intel_crtc_state(crtc->state), pipe_config, true)) {
TO
if (i915.fastboot) {
]
Now display is working with fastboot=1, but XRANDR detects it as a UNKNOWN. If
try to change display orientation, I will get black screen with backlight.
If I use kernel without dirty hack, it detects DSI panel normally, but it's
black.</pre>
