2021-11-05ASoC: SOF: Intel: hda: fix hotplug when only codec is suspendedKai Vehmanen
If codec is in runtime suspend, but controller is not, hotplug events are missed as the codec has no way to alert the controller. Problem does not occur if both controller and codec are active, or when both are suspended. An easy way to reproduce is to play an audio stream on one codec (e.g. to HDMI/DP display codec), wait for other HDA codec to go to runtime suspend, and then plug in a headset to the suspended codec. The jack event is not reported correctly in this case. Another way to reproduce is to force controller to stay active with "snd_sof_pci.sof_pci_debug=0x1" Fix the issue by reconfiguring the WAKEEN register when powering up/down individual links, and handling control events in the interrupt handler.

2021-02-08ASoC: SOF: Intel: hda: release display power at link_powerKai Vehmanen
The i915 display power is requested both by controller (for init and link reset) as well as by codec driver (for codec control). There's an additional constraint that on some platforms frequent changes to display power state may cause visible flicker. To avoid this, the SOF hda controller requests display power whenever it is active and only releases it when runtime suspended. This patch utilizes the new hdac_bus link_power op to plug into HDA link state changes. By monitoring link state changes, we can keep the controller side display power wakeref until the codec driver has completed its work, and only release the wakeref when codec driver is suspended.

Opt-in to use snd_hdac_ext_bus_link_power() to manage HDA link power up/down events. This allows to reduce power consumption in cases where some HDA codecs are suspended, but other child devices (HDA or non-HDA codecs) remain active and controller itself remains in active state. By using snd_hdac_ext_bus_link_power(), the individual HDA links can be powered off and if all HDA codecs are powered down, the command DMA can also be shut down.

2019-08-08ASoC: SOF: Intel: Initialize hdaudio bus properlyTakashi Iwai
The SOF HD-audio bus has its house-made initialization code. It's supposedly for making the code independent from HD-audio bus drivers. However, this is error-prone, and above all, the SOF driver has already dependency on HD-audio bus driver when CONFIG_SND_SOF_HDA is set. That is, if this Kconfig is set, there is no reason to avoid the call to the proper bus init function. Also, the ext_ops that is set at bus initialization can be better handled inside sof_hda_bus_init(). We don't need to refer this outside the bus initialization. So this patch addresses these issues: - sof_hda_bus_init() calls nothing but snd_hdac_ext_bus_init() when CONFIG_SND_SOF_HDA is set. Otherwise some fields are initialized locally like before for avoiding the dependency. - ext_ops is referred inside sof_hda_bus_init(). The ext_ops argument of snd_hda_bus_init() is dropped.

2019-08-08ALSA: hda: Direct MMIO accessesTakashi Iwai
HD-audio drivers access to the mmio registers indirectly via the corresponding bus->io_ops callbacks. This is because some platform (notably Tegra SoC) requires the word-aligned access. But it's rather a rare case, and other platforms suffer from the penalties by indirect calls unnecessarily. This patch is an attempt to optimize and cleanup for this situation. Now the special aligned access is used only when a new kconfig CONFIG_SND_HDA_ALIGNED_MMIO is set. And the HD-audio core itself provides the aligned MMIO access helpers instead of the driver side. If Kconfig isn't set (as default), the standard helpers like readl() or writel() are used directly. A couple of places in ASoC Intel drivers have the access via io_ops reg_writel(), and they are replaced with the direct writel() calls. And now with this patch, the whole bus->io_ops becomes empty, so it's dropped completely. The bus initialization functions are changed accordingly as well to drop the whole bus->io_ops.

2019-08-08ALSA: hda: Remove page allocation redirectionTakashi Iwai
The HD-audio core allocates and releases pages via driver's specific dma_alloc_pages and dma_free_pages ops defined in bus->io_ops. This was because some platforms require the uncached pages and the handling of page flags had to be done locally in the driver code. Since the recent change in ALSA core memory allocator, we can simply pass SNDRV_DMA_TYPE_DEV_UC for the uncached pages, and the only difference became about this type to be passed to the core allocator. That is, it's good time for cleaning up the mess. This patch changes the allocation code in HD-audio core to call the core allocator directly so that we get rid of dma_alloc_pages and dma_free_pages io_ops. If a driver needs the uncached pages, it has to set bus->dma_type right after the bus initialization. This is merely a code refactoring and shouldn't bring any behavior changes.
