Ok, given that this bug is also about gm45 (and not snb as I've originally thought), I presume it's also fixed by the gen4 infoframe fix merged into drm-intel-fixes:
commit c3e897d603e9b0c19c2c65a3ab1cf07fe87da583 Author: Paulo Zanoni <[email protected]> Date: Wed May 2 22:55:43 2012 -0300 drm/i915: enable dip before writing data on gen4 While testing with the intel_infoframes tool on gen4, I see that when video DIP is disabled, what we write to the DATA memory is not exactly what we read back later. This regression has been introduce in commit 64a8fc0145a1d0fdc25fc9367c2e6c621955fb3b Author: Jesse Barnes <[email protected]> Date: Thu Sep 22 11:16:00 2011 +0530 drm/i915: fix ILK+ infoframe support That commit was setting VIDEO_DIP_CTL to 0 when initializing, which caused the problem.
