Just a quick question, is this a regression? If so, can you please attach the output of xrandr --verbose from a noisy and a quite kernel (otherwise just please attach it from this noisy kernel).

The WARN is new, the problem is old.

drm: add generic ioctls to get/set properties on any object

Useless for connector properties (since they already have their own ioctls), but useful when we add properties to CRTCs, planes and other objects.

Before that commit we had no idea that we had run out of property slots. I think the WARN is genuine, but maybe we should just bump the count set it to WARN_ONCE and hope the conversion to lists arrives sooner rather than latter.

Chris is right: this is not a regression. Before that patch, no one checked if property creation really worked. I chose not to use WARN_ONCE because we need to increase the variable once for each time you see the message. Assuming this message appears on your log less than 8 times, does this patch fix your problem?

Just a little more information: you have a lot of connector properties because for some reason the driver thinks you have TV1, TV2 and TV3. Each TV connector has a lot of properties... With kernel 3.3 you have only TV1 and TV2. Maybe instead of increasing the maximum property count we should try to investigate why there's a new TV connector in the new kernel (and maybe this is also not a bug/regression...).

I've merged a patch from Chris to detect additional sdvo TV outputs:

Author: Chris Wilson <[email protected]>
Date:   Fri Sep 30 22:56:41 2011 +0100

drm/i915/sdvo: Include YRPB as an additional TV output type

So that explains that hopefully.
