      drm/i915/vlv: Reset the ADPA in vlv_display_power_well_init() · 9504a892
      Lyude 提交于
      While VGA hotplugging worked(ish) before, it looks like that was mainly
      because we'd unintentionally enable it in
      valleyview_crt_detect_hotplug() when we did a force trigger. This
      doesn't work reliably enough because whenever the display powerwell on
      vlv gets disabled, the values set in VLV_ADPA get cleared and
      consequently VGA hotplugging gets disabled. This causes bugs such as one
      we found on an Intel NUC, where doing the following sequence of
      hotplugs:
      
            - Disconnect all monitors
            - Connect VGA
            - Disconnect VGA
            - Connect HDMI
      
      Would result in VGA hotplugging becoming disabled, due to the powerwells
      getting toggled in the process of connecting HDMI.
      
      Changes since v3:
       - Expose intel_crt_reset() through intel_drv.h and call that in
         vlv_display_power_well_init() instead of
         encoder->base.funcs->reset(&encoder->base);
      
      Changes since v2:
       - Use intel_encoder structs instead of drm_encoder structs
      
      Changes since v1:
       - Instead of handling the register writes ourself, we just reuse
         intel_crt_detect()
       - Instead of resetting the ADPA during display IRQ installation, we now
         reset them in vlv_display_power_well_init()

      drm/i915/vlv: Make intel_crt_reset() per-encoder · 28cf71ce
      Lyude 提交于
      This lets call intel_crt_reset() in contexts where IRQs are disabled and
      as such, can't hold the locks required to work with the connectors.
