Frontbuffer tracking
HW: BYT RVP
Boot from USB with:
1. 1st partition contains grub and kernel bootimage
2. 2nd partition contains rootfs.
Kernel: drm-intel-nightly
Bug description
---------------
After booting up kernel and mouting of rootfs when an Xterm is started using
startx, frontbuffer updates are not tracked in intel_frontbuffer.c
Calls to intel_frontbuffer_flush and intel_fb_obj_invalidate are not made:
1. When moving from console mode to UI mode and vice-versa (F1 and F7)
2. When mouse movements or keystrokes are performed.
In the attached logs, control was moved from F1 to F7 and vice-versa many times
but a flush was seen only for the first time.</pre>
