From: Chris Wilson Date: Thu, 10 Feb 2011 10:05:35 +0000 (+0000) Subject: drm/i915/tv: Use polling rather than interrupt-based hotplug X-Git-Tag: v2.6.38-rc5~2^2~4^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8102e126c0827b5336065fd86d3d313b60fde23a;p=pandora-kernel.git drm/i915/tv: Use polling rather than interrupt-based hotplug The documentation recommends that we should use a polling method for TV detection as this is more power efficient than the interrupt based mechanism (as the encoder can be completely switched off). A secondary effect is that leaving the hotplug enabled seems to be causing pipe underruns as reported by Hugh Dickins on his Crestline.
