screen picture

the fb on the first primary plane with pixel format DRM_FORMAT_YUV420 is the screen fail colored. It could be that YUV will misinterpreted as RGB. If I copy only y data to fb the screen is red with a shadow from the picture. Only u-plane the screen is green and same with v-plane is blue. A picture from the screen are attached.
Tested with kernel 4.10-rc3 and 4.9.

Freedesktop's Bugzilla instance is EOLed and open bugs are about to be migrated to http://gitlab.freedesktop.org.

To avoid migrating out of date bugs, I am now closing all the bugs that did not see any activity in the past year. If the issue is still happening, please create a new bug in the relevant project at https://gitlab.freedesktop.org/drm (use misc by default).

Sorry about the noise!
