Oh i915 overlays aren't a good reason ;-) I've done those way back when drm didn't have any plane infrastructure and pretty much as my very contribution. So totally lacked any clue. If I can scrap together a bit of time I want to port the legacy overlay code over to drm planes (and remap the current ioctl interface to the drm plane interface for backwards compat). But atm that's crushed under a giant pile of other todo items. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch
