Oh OK. > We are still missing DSI command mode support, and moving it to the common DRM model. Nope, DSI command mode support has been working just fine for a while now :) And Sebastian has a WIP git tree of the common DRM model changes for it. I don't think we have devices with DSI command mode working for omapfb but not for omapdrm? What got missed for v5.6-rc1 is the LCD backlight patch though, I think the only issue there is default-brightness vs more common default-brightness-value usage if you have any input to that. > > > This is probably known, but for devices that would like use PowerVR SGX, > > > there sometimes is only userspace available that works with omap(l)fb, > > > and not with DRM.

OK so then the only blocker seems to be the lack of SGX blobs for omap3 devices which seems to be in process of getting fixed. Regards, Tony
