This has been a problem in many ways: first of all, it goes through the hardware event transition (from GPU register write, HD-audio controller trigger, and finally to HD-audio unsolicited event handling), which is often unreliable and may miss some opportunities. Second, each unsol event handling and ELD read-up need the explicit power up / down when the codec is in the runtime suspend. Last but not least, which is the most important, the hotplug wakeup may be missed when the HD-audio controller is in runtime suspend. Especially the last point is a big problem due to the recent change relevant with vga_switcheroo that forcibly enables the runtime PM for AMD HDMI controllers. These issues are solved by introducing the audio component; the hotplug notification is done by a direct function callback, which is more accurate and reliable, and it can be processed without the actual hardware access, i.e. no runtime PM trigger is needed, and the HD-audio gets the event even if it's in runtime suspend. The same for ELD query, as it's read directly from the cached ELD bytes stored in the DRM driver, hence the whole hardware access can be skipped. So here it is: this patch implements the audio component binding with AMD/ATI DRM driver. The biggest difference from i915 implementation is that this binding is fully optional and it can be enabled asynchronously on the fly. That is, the driver will switch from the HD-audio unsolicited event to the notify callback once when the DRM component gets bound. Similarly, when DRM driver gets unloaded, the HDMI event handling returns to the legacy mode, too. Also, another difference from i915 is that AMD HDMI registers the component in the codec driver, while i915 HDMI codec assumes the component binding was already done. Hence AMD code does de-register the component binding at the codec exit, too. Some other details: - The match component ops assumes that both VGA and HD-audio controller PCI entries belong to the same PCI bus, and only accepts such an entry. - The pin2port audio_ops is implemented with assumption of the widget NID starting from 3, with step 2 (3, 5, 7, ...). As of this patch, the DRM component in radeon and amdgpu DRM driver sides isn't implemented yet, so this change won't give any benefit alone. By the following changes in DRM sides, the mission will be completed.
