| * ALSA: usb - Add boot quirk for C-Media 6206 USB AudioDan Allongo2009-06-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Added boot quirk for C-Media CM6206 device in snd_usb_audio_probe. The function snd_usb_cm6206_boot_quirk sets up six internal 16-bit registers in order to initialize the device. Values for the registers came from sniffing USB traffic under Windows since only four of the six are documented in the datasheet for CM106 and some reserved bits were also being set.

* | sound: usb-audio: make the MotU Fastlane work againClemens Ladisch2009-05-27
|/ | | | | | | | | | | | | Kernel 2.6.18 broke the MotU Fastlane, which uses duplicate endpoint numbers in a manner that is not only illegal but also confuses the kernel's endpoint descriptor caching mechanism. To work around this, we have to add a separate usb_set_interface() call to guide the USB core to the correct descriptors.

* sound: usb-audio: allow period sizes less than 1 msClemens Ladisch2009-04-06
| | | | | | | | | | To enable periods shorter than 1 ms, we have to make sure that short periods are only available for alternate settings that have a small enough data packet interval. Furthermore, the code that aligns URBs to USB frames is now superfluous. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* sound: usb-audio: save data packet interval in audioformat structureClemens Ladisch2009-04-06
| | | | | | | | | The data packet interval needs to be available in the audioformat structure, together with the other audio format parameters, so that it can be used to influence ALSA hardware parameters.

* sound: usb-audio: remove check_hw_params_convention()Clemens Ladisch2009-04-06
| | | | | | | | | | | | | This removes the check_hw_params_convention() function because 1) it is not necessary, as the hw_rule_* functions also work correctly (i.e., as no-ops) when the device supports all combinations of the audio format parameters; and 2) it would become too complex when adding a fourth altsetting-dependent hardware parameter, as this would require another three loops to check dependecies with rate/channels/format.

* sound: usb-audio: show sample format width in proc fileClemens Ladisch2009-04-06

| * sound: usb-audio: fix queue length check for high speed devicesClemens Ladisch2009-03-02
| | | | | | | | | | | | | | | | | | | | When checking for the maximum queue length, we have to take into account that MAX_QUEUE is measured in milliseconds (i.e., frames) while the unit of urb_packs is whatever data packet interval the device uses (possibly less than one frame when using high speed devices).

| * sound: usb-audio: fix rules check for 32-channel devicesClemens Ladisch2009-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | When storing the channel numbers used by a format, and if the device happens to support 32 channels, the code would try to store 1<<32 in a 32-bit value. Since no valid format can have zero channels, we can use 1<<(channels-1) instead of 1<<channels so that all the channel numbers that we test for fit into 32 bits.

| * sound: usb-audio: make URB sizes more equalClemens Ladisch2009-01-26
| | | | | | | | | | | | | | | | | | | | Distribute the packets evenly among the URBs, instead of making all URBs except the last one to have the maximum size. This makes the timing of pointer updates more regular and removes some special cases from the code. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
| * sound: usb-audio: limit playback queue lengthClemens Ladisch2009-01-26
| | | | | | | | | | | | | | | | | | | | Once our URBs contain enough packets, queueing more URBs does not give us any additional underrun protection (as we use double-buffering) but just increases latency unnecessarily. Therefore, we try to limit the queue length to some reasonable value. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | When sending a silence URB (before playback has started, or when it is paused), use the number of frames that would be normally sent instead of a single frame so that the rate at which completion interrupts arrive is consistent.

| | | | | | | | | | | | | | | | | | | | | | | | The CM6207 incorrectly advertises its 96 kHz playback setting as 48 kHz in its USB device descriptor.

|/ | | | | | | | | | | | For audio devices that do not have proper audio descriptors (e.g., Edirol UA-20), we use hardcoded parameters from our quirks list. However, we must still read the maximum packet size from the standard endpoint descriptor; otherwise, we might use packets that are too big and therefore rejected by the USB core.

I think that's the mentioned synchronizing-problem in the UA-1000 quirk ('FIXME: playback must be synchronized to capture'), so I didn't change that.
