... by writing (anything) to i915_error_state. This way we can simulate a bunch of gpu hangs and run the error_state capture code every time (without the need to reload the module). To make that happen we need to abandon the simple seq_file wrappers provided by the drm core. While at it put the new error_state refcounting to some good use and associated the error_state to the debugfs when opening the file. Otherwise the error_state could change while someone is reading it. This should help greatly when we finally get around to split up the giant single seq_file block that the error_state file currently is into smaller parts. v2: Actually squash all the fixes into the patch ...
