Qualcomm development of the MSM SOC framebuffer driver has diverged significantly from the driver used by Android. This is a snapshot of our current driver, in all it's agony. We are putting this in staging to help with the process of converging the two drivers. At this point, the driver has been tested only in dumb framebuffer mode.
