| | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid traversing the device object list of the card instance just for checking the PCM streams. The driver's private object already contains the array of substream pointers, so it can be simply looked through. The card internal may be restructured in future, thus better not to rely on it.

* ALSA: usb: Fix wrong mapping of RLC and RRC channelsAnssi Hannula2013-11-111-2/+2
| | | | | | | | | | | | | | | | | | According to USB Audio spec v2 bits 25 and 26 of bmChannelConfig are "Back Left of Center - BLC" and "Back Right of Center - BRC", respectively. They are currently assigned to ALSA channels BLC/BRC. However, the ALSA BLC/BRC are actually the rather nonsensical "bottom left center" and "bottom right center", so the channels will be assigned wrongly. The comments in the USB code are also similarly wrong, so this is not readily apparent without looking at the actual specification. Fix the channel mapping by mapping bits 25 and 26 to RLC (Rear Left Center) and RRC (Rear Right Center), respectively, instead.

But the complete lack of channel map for a format leads userspace to believe that the format is not available at all. Or am I misunderstanding how this should be used?

Currently the driver allocates too few URBs for endpoints that don't use implicit sync, making underruns more likely to occur. This may be a holdover from before I/O delays could be measured accurately; in any case, it is no longer necessary. The patch allocates as many URBs as possible, subject to four limitations: The total number of URBs for the endpoint is not allowed to exceed MAX_URBS (which the patch increases from 8 to 12). The total number of packets per URB is not allowed to exceed MAX_PACKS (or MAX_PACKS_HS for high-speed devices), which is decreased from 20 to 6. The total duration of queued data is not allowed to exceed MAX_QUEUE, which is decreased from 24 ms to 18 ms. The total number of ALSA frames in the output queue is not allowed to exceed the ALSA buffer size. The last requirement is the hardest to implement. Currently the number of URBs needed to fill a buffer cannot be determined in advance, because a buffer contains a fixed number of frames whereas the number of frames in an URB varies to match shifts in the device's clock rate. To solve this problem, the patch changes the logic for deciding how many packets an URB should contain. Rather than using as many as possible without exceeding an ALSA period boundary, now the driver uses only as many packets as needed to transfer a predetermined number of frames. As a result, unless the device's clock has an exceedingly variable rate, the number of URBs making up each period (and hence each buffer) will remain constant. The overall effect of the patch is that playback works better in low-latency settings. The user can still specify values for frames/period and periods/buffer that exceed the capabilities of the hardware, of course. But for values that are within those capabilities, the performance will be improved. For example, testing shows that a high-speed device can handle 32 frames/period and 3 periods/buffer at 48 KHz, whereas the current driver starts to get glitchy at 64 frames/period and 2 periods/buffer. A side effect of these changes is that the "nrpacks" module parameter is no longer used. The patch removes it.

| * ALSA: usb-audio: do not trust too-big wMaxPacketSize valuesClemens Ladisch2013-08-081-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver used to assume that the streaming endpoint's wMaxPacketSize value would be an indication of how much data the endpoint expects or sends, and compute the number of packets per URB using this value. However, the Focusrite Scarlett 2i4 declares a value of 1024 bytes, while only about 88 or 44 bytes are be actually used. This discrepancy would result in URBs with far too few packets, which would not work correctly on the EHCI driver. To get correct URBs, use wMaxPacketSize only as an upper limit on the packet size.
