Hi Anup,

Check out the dragonboard-drm branch on my kernel tree:

https://github.com/freedreno/kernel-msm/commits/dragonboard-drm

I've also just uploaded the latest prebuilt kernel I have laying around to:

http://people.freedesktop.org/~robclark/f20/dragonboard-boot.img

The same userspace build will work on any of the devices.  I use same
fedora 20 filesystem on a hardrive which I just plug into whichever of
the boards (bstem, inforce, or apq8074 dragonboard) that I happen to
be using at the time.

fwiw, the biggest difference between apq8x74 and apq8064/8060a is the
display controller block (mdp5 vs mdp4).  I have not yet implemented
hw cursor or overlay/plane support for mdp5.  So you need to enable sw
cursor on the dragonboard by uncommenting a line in
/etc/X11/xorg.conf.d/90-freedreno.conf

BR,
