I was surprised that my BARTS in a Samsung notebook doesn't have a RADEON_IS_IGP flag.

Barts is a discrete chip. the IGP flag is only set for integrated parts and APUs.

Are there any DCE5 devices that are IGP?

No. Ontario and and llano are DCE4.x and trinity is DCE 6.x.

Btw. who does set that "flags" anyway? Flags are passed to the radeon_driver_load_kms function from drm_pci.c: dev->driver->load(dev, ent->driver_data); (so driver_data becomes flags). But I can't find where that "driver_data" (AKA flags) is set.

It's the last field in: include/drm/drm_pciids.h
