They require an AVI InfoFrame with a proper Pixel Repetition field.
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=45729 Signed-off-by: Paulo Zanoni paulo.r.zanoni@intel.com
I'm still waiting for confirmation on bugzilla, but I have access to a TV that reproduces the problem and the problem goes away with this patch series.
Shouldn't all this infoframe stuff be shared between the drivers (like e.g. EDID stuff is)? I see i915, radeon, nouveau all have separate implementations of it, and i915 seems to have it even twice (in intel_hdmi.c and intel_sdvo.c).
The patch below only fixes the issue on one of those four places where the avi/video infoframe is generated.
