A while ago, Ben added support for Quanta devices that had the display hardware fused off. We can a bit more general than that by reading the FUSE_STRAP register and setting num_pipes to 0 when detecting such condition. To achieve that, the intel_device_info structure in dev_priv needed to be made writable, that's patch 1. Patches 2 to 5 build the support for reading out FUSE_STRAP on IVB+, client platforms only to detect both "display fused off" and "pipe C fused off" configurations. Patch 6 removes the Quanta special-case with the (reasonable) hope that it's now covered by the DISPLAY_DISABLE bit. Patch 7 is a bonus, somewhat unrelated, little clean-up patch. This series is not tested due to lack of such a device, I was hoping Ben still had the device around somewhere and could give this series a go. _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
