Some architectures like PARISC is known not to support mmap properly with the DMA buffer, where dma_mmap_coherent() returns -EINVAL unconditionally. From the API POV, we should rather drop the mmap support there and expose it before the user-space tries to call mmap. The patch contains again ugly ifdef's, unfortunately, as there is no global flag indicating this. Once when such macro is defined, we can get rid of this instead.

As of now the pointer to struct dai is not being used anywhere in the function. So it is safe to remove the variable. If we are ever doing anything with the container_of(daio, struct dai, daio), then at that time we can again add the variable.

In the scenario where there is one "Line Out", one "Speaker" and one "Headphone", and there are only two DACs, two outputs will share a DAC. Currently any mixer on such a DAC will get the "PCM" name, which is misleading. Instead use "Headphone+LO" or "Speaker+LO" to better specify what the volume actually controls.

The ELD ALSA control change event is sent by hdmi_present_sense() when eld_changed is true. Currently, it is only true when the ELD buffer contents have been modified. However, the user-visible ELD controls also change to a zero-length value and back when eld_valid is unset/set, and no event is currently sent in such cases (such as when unplugging or replugging a sink). Fix the code to always set eld_changed if eld_valid value is changed, and therefore to always send the change event when the user-visible value changes.

Since we're calling request_module() asynchronously now, we can get rid of the autoload lock in snd_seq_device_register_driver(), as well as in the snd-seq driver registration itself. This enables the automatic loading of dependent sequencer modules, such as snd-seq-virmidi from snd-emu10k1-synth. Signed-off-by: NTakashi Iwai <tiwai@suse.de>

由 Takashi Iwai 提交于
Currently the sequencer module binding is performed independently from the card module itself. The reason behind it is to keep the sequencer stuff optional and allow the system running without it (e.g. for using PCM or rawmidi only). This works in most cases, but a remaining problem is that the binding isn't done automatically when a new driver module is probed. Typically this becomes visible when a hotplug driver like usb audio is used. This patch tries to address this and other potential issues. First, the seq-binder (seq_device.c) tries to load a missing driver module at creating a new device object. This is done asynchronously in a workq for avoiding the deadlock (modprobe call in module init path). This action, however, should be enabled only when the sequencer stuff was already initialized, i.e. snd-seq module was already loaded. For that, a new function, snd_seq_autoload_init() is introduced here; this clears the blocking of autoloading, and also tries to load all pending driver modules.

The emu10k1 voice allocator takes voice_lock spinlock. When there is no empty stream available, it tries to release a voice used by synth, and calls get_synth_voice. The callback function, snd_emu10k1_synth_get_voice(), however, also takes the voice_lock, thus it deadlocks. The fix is simply removing the voice_lock holds in snd_emu10k1_synth_get_voice(), as this is always called in the spinlock context.

One is to switch internal/external for the source and another is to switch word/spdif for the external clock. The IDs for these Selector Function Blocks are 9 and 8. But in current implementation they're 0 and 0.
