Following up the first instance of this series: http://lists.freedesktop.org/archives/dri-devel/2013-August/043125.html Here is a v2 with Ville's review pass and a few additions: - Alternate clock modes for 4k resolutions - HDMI vendor specific infoframe support in drivers/video/hdmi.c - Enabling of those vendor specific infoframes in the i915 driver Along the way, a tegra patch was needed for a small consolidation of the code packing vendor specific infoframes. This patch has only been compile-tested. On Intel, it's possible to read back the programmed infoframe buffers with intel-gpu-tools' intel_infoframe and this gives: Vendor InfoFrame: - frequency: every vsync - raw: f4050181 000c0347 00000320 00000000 00000000 00000000 00000000 00000000 0000004c 00000000 00000000 00000000 00000000 00000000 00000000 00000000 - vendor Id: 0x000c03 (HDMI) - video format: 0x001 - HDMI VIC: 3 after a $ xrandr --output HDMI1 --mode 3840x2160 -r 24 -- Damien _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
