      drm/i915/params: switch to device specific parameters · 8a25c4be
      Jani Nikula authored
      Start using device specific parameters instead of module parameters for
      most things. The module parameters become the immutable initial values
      for i915 parameters. The device specific parameters in i915->params
      start life as a copy of i915_modparams. Any later changes are only
      reflected in the debugfs.
      
      The stragglers are:
      
      * i915.force_probe and i915.modeset. Needed before dev_priv is
        available. This is fine because the parameters are read-only and never
        modified.
      
      * i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and
        I915_STATE_WARN_ON would result in massive and ugly churn. This is
        handled by not exposing the parameter via debugfs, and leaving the
        parameter writable in sysfs. This may be fixed up in follow-up work.
      
      * i915.inject_probe_failure. Only makes sense in terms of the module,
        not the device. This is handled by not exposing the parameter via
        debugfs.
