[Bug 41561] [r600 KMS] Hotplug detect does not work for HDMI monitor on Fusion E-350 board

--- Comment #3 from Simon Farnsworth simon.farnsworth@onelan.co.uk 2011-10-07 09:26:08 PDT --- So, I think I see the proximate cause of the bug, but not the reason for it:

In radeon_dvi_detect at radeon_connectors.c:962, I see:

if (!force) { ret = connector->status; goto out; }

A HPD interrupt causes output_poll_execute at drm_crtc_helper.c:897 to execute connector->status = connector->funcs->detect(connector, false); as a result, I cannot see how a hotplug interrupt will ever result in a connector state changing.
