Yes, NetBSD/Xen can't use DRI-based drivers, because in our DRI implementation the physical to machine mapping of addresses isn't handled. Fixing this probably requires an extention of the bus_dma(9) API, and then fixing the DRI implementation to use bus_dma(9). I would expect VESA to work the same way in native of Xen, though. -- Manuel Bouyer <[email protected]> NetBSD: 26 ans d'experience feront toujours la difference --
