This commit is a part of preparation to perform allocation/release of isochronous resources in pcm.hw_params/hw_free callbacks. This commit splits out an operation to configure stream parameters into pcm.hw_params callback. In pcm.prepare callback, establishing connections and start isochronous contexts. Signed-off-by:

In former commits, ALSA oxfw driver handles two isochronous contexts at the same time, except for some devices which supports one endpoint of isochronous packet stream. This commit renames some helper functions so that they handles duplex streams. Signed-off-by:

Response tag only occupies 6 bits, not 7. This bug is harmless, since the value has just been shifted to the right by 26 bits, so this is only a cosmetic fix. Signed-off-by:

After bus reset, isochronous resource manager releases all of allocated isochronous resources. The nodes to transfer isochronous packet should request reallocation of the resources. However, between the bus-reset and invocation of 'struct fw_driver.update' handler, ALSA PCM application can detect this situation by XRUN because the target device cancelled to transmit packets once bus-reset occurs. Due to the above mechanism, ALSA fireface driver just stops packet streaming in the update handler, thus pcm.prepare handler should request the reallocation. This commit requests the reallocation in pcm.prepare callback when bus generation is changed. Signed-off-by:

Once allocated, isochronous resources are available for packet streaming, even if the streaming is cancelled. For this reason, current implementation handles allocation of the resources and starting packet streaming at the same time. However, this brings complicated procedure to start packet streaming. This commit separates the allocation and starting. The allocation is done in pcm.hw_params callback and available till pcm.hw_free callback. Even if any XRUN occurs, pcm.prepare callback is done to restart packet streaming without releasing/allocating the resources. There are two points to stop packet streaming; in pcm.hw_params and pcm.prepare callbacks. The former point is a case that packet streaming is already started for any MIDI substream then packet streaming is requested with different sampling transfer frequency for any PCM substream. The latter point is cases of any XRUN or packet queueing error. Signed-off-by:

This commit is a part of preparation to perform allocation/release of isochronous resources in pcm.hw_params/hw_free callbacks. This commit adds a helper function to allocate isochronous resources, separated from operations to start packet streaming, I note that some dice-based devices have two pair of endpoints for isochronous packet straeming.

This commit is a part of preparation to perform allocation/release of isochronous resources in pcm.hw_params/hw_free callbacks.

The Emagic Unitor 8 does not provide iManufacturer and iProduct fields in its device descriptor. These fields are used by alsa to make build the device name. Thus uncomment the .product-name in the quirks-table. Without this change the device shows up as 'USB Device 0x86a:0x01'.
