That looks cleaner. Obviously my only concern is what happens if we ever see a second device that posts without setting up the registers. We may as well compile in the VBT for every single manufactured device... Or we could add a ROM table the manufacturers must include that provides the necessary register values for their hardware. There must be some replacement for the BIOS, a device description table at least? Does any one have a strong "this will damage my hardware" objection? Are the values safe enough for *any* device? -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
