* [ALSA] usb-audio: start submitting URBs in the prepared stateClemens Ladisch2005-11-041-38/+62
| | | | | | | | | | | | | | | | | | Modules: USB generic driver If we submit all our URBs when a playback stream is started, the first hwptr_done update for each URB happens at the same time. This results in an underrun when there isn't enough PCM data available at this point for all URBs. To avoid this, we begin submitting our URBs earlier (when the stream is prepared), with empy packets. When the stream is started, the prepare_playback_urb() call for each URB will be run only when the respective URB has completed previously, so the first hwptr_done updates will be done nicely staggered.

* [PATCH] USB: URB_ASYNC_UNLINK flag removed from the kernelAlan Stern2005-09-081-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 29 July 2005, Cambridge, MA: This afternoon Alan Stern submitted a patch to remove the URB_ASYNC_UNLINK flag from the Linux kernel. Mr. Stern explained, "This flag is a relic from an earlier, less-well-designed system. For over a year it hasn't been used for anything other than printing warning messages." An anonymous spokesman for the Linux kernel development community commented, "This is exactly the sort of thing we see happening all the time. As the kernel evolves, support for old techniques and old code can be jettisoned and replaced by newer, better approaches. Proprietary operating systems do not have the freedom or flexibility to change so quickly." Mr. Stern, a staff member at Harvard University's Rowland Institute who works on Linux only as a hobby, noted that the patch (labelled as548) did not update two files, keyspan.c and option.c, in the USB drivers' "serial" subdirectory. "Those files need more extensive changes," he remarked. "They examine the status field of several URBs at times when they're not supposed to. That will need to be fixed before the URB_ASYNC_UNLINK flag is removed." Greg Kroah-Hartman, the kernel maintainer responsible for overseeing all of Linux's USB drivers, did not respond to our inquiries or return our calls. His only comment was "Applied, thanks."

* [ALSA] usb-audio: throttle MIDI URB resubmits on USB errorsClemens Ladisch2005-08-301-13/+64
| | | | | | | | | USB generic driver When a USB error occurs that might indicate that the device has been unplugged, don't resubmit the URB immediately to prevent flooding the log with error messages before khubd has us disconnect()ed. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* [ALSA] usb-audio: fix Emagic MIDI protocol handlingClemens Ladisch2005-08-301-5/+12
| | | | | | | | USB generic driver Emagic devices pad their packets not with 0xff bytes but with a 0xff byte followed by garbage, so we have to stop at the first such byte. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* [ALSA] usb-audio: use vmalloc for the PCM bufferClemens Ladisch2005-08-301-9/+44
| | | | | | | | | USB generic driver With the double buffering, we no longer need contiguous memory for the PCM buffer, so we can use vmalloc() instead of the preallocation functions, and increase the maximum size to 256 KB. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* [ALSA] usb-audio: use usb_buffer_alloc/freeClemens Ladisch2005-08-302-23/+46
| | | | | | | | USB generic driver Use the USB buffer allocation functions to avoid repeated DMA mappings of our buffers, which are re-used quite a lot. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* [ALSA] usb-audio: properly lock hwptr_done accessesClemens Ladisch2005-08-301-2/+8
| | | | | | | | USB generic driver Take the substream lock when reading hwptr_done to avoid a race condition with the updates in the URB callbacks. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* [ALSA] usb-audio: actually schedule playback URBs at frame boundariesClemens Ladisch2005-08-301-1/+7
| | | | | | | | USB generic driver Change prepare_playback_urb() not to stop preparing packets before a frame boundary has been reached. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* [ALSA] usb-audio: double-buffer all playback dataClemens Ladisch2005-08-301-86/+65
| | | | | | | | | | | | | | | USB generic driver We always had to use double buffering when capturing, and when playback data for one URB crosses a buffer boundary. The latter would make hwptr updates less precise because the double-buffered data is read from the buffer much earlier than the other data is read by the host controller. Double-buffering all data allows to update hwptr immediately after the data was copied to the USB buffer(s), which has the additional benefit of avoiding the latency imposed by the host controller's delay of up to one frame when interrupting. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* [ALSA] usb-audio: optimize handling of capture URBsClemens Ladisch2005-08-301-18/+8
| | | | | | | | | | | | | | USB generic driver When preparing capture URBs, we don't need to stop when we cross a period boundary because we now never handle more than one millisecond of data per URB anyway. When handling captured data, use an extra flag to call snd_pcm_period_elapsed() no more than once. This allows us to move the period boundary checking code before the copying of the data which avoids a second locking of the substream's lock. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* [ALSA] usb-audio: schedule high speed URBs with 1 ms alignmentClemens Ladisch2005-08-301-6/+14
| | | | | | | | | USB generic driver The EHCI driver doesn't interrupt more than once per millisecond, and organizes all iso transfers with frame-sized ITDs, so we can (try to) be more efficient by aligning all URBs on frame boundaries. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* [ALSA] usb-audio: make nrpacks parameter writeableClemens Ladisch2005-08-301-3/+5
| | | | | | | | USB generic driver The nrpacks module parameter is used only when initializing a playback stream, so it doesn't hurt to make it writeable. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* [ALSA] usb-audio: fix packets per URB calculation for playbackClemens Ladisch2005-08-301-1/+9
| | | | | | | | | | USB generic driver When determining how many packets are needed for one period, we cannot assume that all packets have their maximum size -- we always use the nominal sample rate when sending data, and could use an even lower rate when the endpoint uses frequency feedback. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
* [ALSA] usb-audio: use 1 ms URBs when capturingClemens Ladisch2005-08-301-6/+12
| | | | | | | | | | | | | USB generic driver When capturing audio data, we do not know beforehand how many samples the device sends per frame, so we have to use URBs that are as short as possible to make sure that we can handle period boundaries without any additional latencies. Furthermore, the total count of URBs submitted doesn't matter when capturing, so we can just use the maximum number. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

| | | | | | | | | | PCM Midlevel,ALSA<-OSS emulation,USB USX2Y This patch removes open_flag from struct _snd_pcm_substream.

* [PATCH] clean up inline static vs static inlineJesper Juhl2005-07-272-6/+6
| | | | | | | | | | | | | | | `gcc -W' likes to complain if the static keyword is not at the beginning of the declaration. This patch fixes all remaining occurrences of "inline static" up with "static inline" in the entire kernel tree (140 occurrences in 47 files). While making this change I came across a few lines with trailing whitespace that I also fixed up, I have also added or removed a blank line or two here and there, but there are no functional changes in the patch.

* [ALSA] usb-audio - avoid unnecessary double bufferingClemens Ladisch2005-05-291-0/+2
| | | | | | | | | | | | USB generic driver When a USB packet boundary falls exactly on a buffer boundary, hwptr remains at the end of the buffer which causes an overflow in the next iteration and triggers double buffering although the next packet would actually be contiguous. This patch ensures that hwptr is always smaller than buffer_size. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
