Ville Syrjälä 4488496d58 drm/i915: Fix deadlock in i830_disable_pipe() ... i830_disable_pipe() gets called from the power well code, and thus we're already holding the power domain mutex. That means we can't call plane->get_hw_state() as it will also try to grab the same mutex and will thus deadlock. Replace the assert_plane() calls (which calls ->get_hw_state()) with just raw register reads in i830_disable_pipe(). As a bonus we can now get a warning if plane C is enabled even though we don't even expose it as a drm plane. v2: Do a separate WARN_ON() for each plane (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Fixes: d87ce76402 ("drm/i915: Add .get_hw_state() method for planes") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20171129125411.29055-1-ville.syrjala@linux.intel.com (cherry picked from commit 5816d9cbc0) Signed-off-by: Jani Nikula <jani.nikula@intel.com>		2018-01-15 16:46:33 +02:00
