Unfortunately, other devices (e.g. Philips Wecall) with the very same

Currently, USB-audio driver allocates the PCM buffer via vmalloc(), as
this serves merely as an intermediate buffer that is copied to each
URB transfer buffer. This works well in general on x86, but on some
archs this may result in cache coherency issues when mmap is used.
OTOH, it works also on such arch unless mmap is used.
This patch is a step for mitigating the inconvenience; a new module
option "use_vmalloc" is provided so that user can choose to allocate
the DMA coherent buffer instead of the existing vmalloc buffer.
The drawback is that it'd be the standard dma_alloc_coherent() calls
and the system would require contiguous pages on non-x86 archs.
Note that it's a global option and not dynamically switchable since
the buffer is pre-allocated at the probe time. In theory, it's
possible to be switchable, but it'd be trickier and racier.
As default use_vmalloc option is set to true, so that the old behavior
is kept. For allowing the coherent mmap on ARM or MIPS, pass
use_vmalloc=0 option explicitly.

This adds support for the UAC3 insertion controls. The status
is reported as a boolean value in the same way it used to do
for UAC2. Hence, the presence of any connector in the response
will make the control saying the jack is connected.
The UAC2 support for this control has been moved to a dedicated
control for connectors as both UAC2 and UAC3 follow a specific
Control Request Parameter Block for this control. This parameter
block for UAC3 could not be read in the same simplistic
manner as in UAC2.
This implementation is not requesting additional information
from the HIGH CAPABILITY Connectors descriptor.
Tested with an UAC3 device with UAC2 as legacy configuration.
The connector status can be read with `amixer` and the interrupt
is also caught with `alsactl monitor`.

Signed-off-by: Takashi Iwai <tiwai@suse.de>
Historically USB-audio driver sets the card's longname field with the
details of the device and the bus information. It's good per se, but
not preferable when it's referred as the identifier for UCM profile.
This patch adds a quirk profile_name field to override the card's
longname string to a pre-defined one, so that one can create a unique
and consistent ID string for the specific USB device via a quirk table
to be used as a UCM profile name.
The patch does a slight code refactoring to split out the functions to
set shortname and longname fields as well.

This patch adds "Keep Interface" control for each USB-audio device.
The control element is with SND_CTL_IFACE_CARD, so that it won't
appear on any sane mixer applications. For a device that is confirmed
to work well with "keep-interface" mode, user can flip the control via
amixer, e.g.
% amixer -c1 cset iface=CARD,name='Keep Interface' on
and save/restore the state via alsactl.
The reason to provide this via control API is that the behavior must
be pretty depending on the device (and the firmware in it), so it's
not ideal to apply via module option.
For a device that certainly works, we may set it statically via a
quirk table entry. But a device like Dell WD15 dock behaves so
differently depending on the firmware, and we can't set it
statically. So leave this as a dynamic switch each user can adjust
freely.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
Introduce a new flag to struct snd_usb_audio for allowing the device
to skip usb_set_interface() calls at changing or closing the stream.
As of this patch, the flag is nowhere set, so it's just a place
holder. The dynamic switching will be added in the following patch.
A background information for this change:
Dell WD15 dock with Realtek chip gives a very long pause at each time
the driver changes the altset, which eventually happens at every PCM
stream open/close and parameter change. As the long pause happens in
each usb_set_interface() call, there is nothing we can do as long as
it's called. The workaround is to reduce calling it as much as
possible, and this flag indicates that behavior.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
This is a preliminary change for the upcoming quirk implementation.
Currently USB-audio driver tries to call usb_set_interface() whenever
the format change with interface/altset modification happens. In this
patch, the check is replaced with the comparison of cur_altsetting and
the targeted altsetting pointer, so that the driver may skip the
unnecessary function calls.

In the early commit adcdd0d5a1 ("ALSA: usb-audio: Skip volume
controls triggers hangup on Dell USB Dock"), we add the mixer quirks
for Dell dock to skip two mixer FU's for playback. This supposed that
the device has always the proper initial volume, but it doesn't seem
always correct.
This patch adds the explicit initialization of the volumes to the
fixed 0dB at the device probe time. Also, such a fixup is needed
after the resume, so a new function is hooked to the resume callback
as well.
