This patch refactors the processing units min/max calculation logic for the mixer controls and fixes an issue where the Mode Select checking of the Up/Down mixers doesn't differentiate between the UAC1 and UAC2 Control Selector (0x02) and the UAC3 one which is different (0x01). Signed-off-by:

The Audio Control interface descriptor subtypes do not match across all the UAC versions. That makes reusability of the "virtual type" (Mixer, Processors, Selectors, etc) terminals difficult. It also makes the mixer get the default names for the virtual terminals wrong due to the overlap. This patch proposes an unified approach by always using the most comprehensive spec version to define them all (in this case UAC3). Signed-off-by:

This patch adds support for the Processig Units defined in the UAC3 spec. The main difference with the previous specs is the lack of on/off switches in the controls for these units and the addiction of the new Multi Function Processing Unit. The current version of the UAC3 spec doesn't define any useful controls for the new Multi Function Processing Unit so no control will get created once this unit is parsed. Signed-off-by:

Current support for UAC2 Processing Units does the parsing as one control per bit in the bitmap. However, the UAC2 spec defines the controls as bit pairs where b01 means read-only and b11 means read/write control. This patch fixes that and uses the helper functions for checking controls readability/writability when the control is defined as bit pairs (UAC2 and UAC3). Signed-off-by:

This patch add support for Selector Units and Clock Selector Units defined in the new UAC3 spec. Selector Units play a really important role in the new UAC3 spec as Processing Units do not define an on/off switch control anymore. This forces topology designers to add bypass paths in the topology to enable/dissable the Processing Units. Signed-off-by:

Without this commit the following intervals [x y), (x y) were be replaced to (y-1 y) by snd_interval_refine_last(). This was also done if y-1 is part of the previous interval. With this changes it will be replaced with [y-1 y) in case of y-1 is part of the previous interval. A similar behavior will be used for snd_interval_refine_first().

Currently ALSA core blocks userspace for about 10 seconds for PCM R/W IO. This needs to be configurable for modern hardware like DSPs where no pointer update in milliseconds can indicate terminal DSP errors. Add a substream variable to set the wait time in ms. This allows userspace and drivers to recover more quickly from terminal DSP errors. Signed-off-by:

Basically the xrun injection routine can simply call the standard helper snd_pcm_stop_xrun(), but with one exception: it may be called even when the stream is closed. Make snd_pcm_stop_xrun() more robust and check the NULL runtime state, and simplify xrun injection code by calling it. Signed-off-by: -
Takashi Iwai authored
The PCM xrun injection triggers directly snd_pcm_stop() without the standard xrun handler, hence it's not recorded on the event buffer. Ditto for snd_pcm_stop_xrun() call and SNDRV_PCM_IOCTL_XRUN ioctl. They are inconvenient from the debugging POV. Let's make them to trigger XRUN via the standard helper more consistently.

The USB completion callback does not disable interrupts while acquiring the lock. We want to remove the local_irq_disable() invocation from __usb_hcd_giveback_urb() and therefore it is required for the callback handler to disable the interrupts while acquiring the lock. The callback may be invoked either in IRQ or BH context depending on the USB host controller. Use the _irqsave() variant of the locking primitives. Signed-off-by:

Both calls to of_find_node_by_name() and of_get_next_child() return a node pointer with refcount incremented thus it must be explicidly decremented here after the last usage. As we are assured to have a refcounted np either from the initial of_find_node_by_name(NULL, name); or from the of_get_next_child(gpio, np) in the while loop if we reached the error code path below, an x of_node_put(np) is needed.

When i915 component binding fails, it means that HDMI isn't applicable anyway. Although the probe with the generic HDMI parser would still work, it's essentially useless, hence better to be left unbound. This patch mimics the probe_id field at failing the i915 component binding so that the generic HDMI won't be bound after that. Signed-off-by: -

Remove memory allocation within snd_hdac_ext_bus_device_init, to make its behaviour identical to snd_hdac_bus_device_init.

Split snd_hda_codec_new into two separate functions. snd_hda_codec_device_init allocates memory and registers with bus. snd_hda_codec_device_new initialializes the fields and performs snd_device_new. This enables reuse of legacy HDA codec drivers as ASoC codec drivers. In addition mark some functions with EXPORT_SYMBOL_GPL so that it can be called by ASoC wrapper around the legacy HDA driver (hdac_hda). Signed-off-by:

The in_pm atomic in hdac_device is an important field used as a flag as well as a refcount for PM. The existing snd_hdac_power_up/down helpers already refer to it in the HD-audio core code, while the code to actually setting the value (atomic_inc() / _dec()) is open-coded in HDA legacy side, which is hard to find. This patch adds the helper functions to set/reset the in_pm counter to HDA core and use them in HDA legacy side, for making it clearer who / where the PM is managed. There is no functional changes, just code refactoring. Reviewed-by:
