+ * usbusy2y.c - ALSA USB US-428 Driver
+ *
+2005-04-14 Karsten Wiese
+ Version 0.8.7.2:
+ Call snd_card_free() instead of snd_card_free_in_thread() to prevent oops with dead keyboard symptom.
+ Tested ok with kernel 2.6.12-rc2.
+
+2004-12-14 Karsten Wiese
+ Version 0.8.7.1:
+ snd_pcm_open for rawusb pcm-devices now returns -EBUSY if called without rawusb's hwdep device being open.
+
+2004-12-02 Karsten Wiese
+ Version 0.8.7:
+ Use macro usb_maxpacket() for portability.
+
+2004-10-26 Karsten Wiese
+ Version 0.8.6:
+ wake_up() process waiting in usX2Y_urbs_start() on error.
+
+2004-10-21 Karsten Wiese
+ Version 0.8.5:
+ nrpacks is runtime or compiletime configurable now with tested values from 1 to 4.
+
+2004-10-03 Karsten Wiese
+ Version 0.8.2:
+ Avoid any possible racing while in prepare callback.
+
+2004-09-30 Karsten Wiese
+ Version 0.8.0:
+ Simplified things and made ohci work again.
+
+2004-09-20 Karsten Wiese
+ Version 0.7.3:
+ Use usb_kill_urb() instead of deprecated (kernel 2.6.9) usb_unlink_urb().
+
+2004-07-13 Karsten Wiese
+ Version 0.7.1:
+ Don't sleep in START/STOP callbacks anymore.
+ us428 channels C/D not handled just for this version, sorry.
+
+2004-06-21 Karsten Wiese
+ Version 0.6.4:
+ Temporarely suspend midi input
+ to sanely call usb_set_interface() when setting format.
+
+2004-06-12 Karsten Wiese
+ Version 0.6.3:
+ Made it thus the following rule is enforced:
+ "All pcm substreams of one usX2Y have to operate at the same rate & format."
+
+2004-04-06 Karsten Wiese
+ Version 0.6.0:
+ Runs on 2.6.5 kernel without any "--with-debug=" things.
+ us224 reported running.
+
+2004-01-14 Karsten Wiese
+ Version 0.5.1:
+ Runs with 2.6.1 kernel.
+
+2003-12-30 Karsten Wiese
+ Version 0.4.1:
+ Fix 24Bit 4Channel capturing for the us428.
+
+2003-11-27 Karsten Wiese, Martin Langer
+ Version 0.4:
+ us122 support.
+ us224 could be tested by uncommenting the sections containing USB_ID_US224
+
+2003-11-03 Karsten Wiese
+ Version 0.3:
+ 24Bit support.
+ "arecord -D hw:1 -c 2 -r 48000 -M -f S24_3LE|aplay -D hw:1 -c 2 -r 48000 -M -f S24_3LE" works.
+
+2003-08-22 Karsten Wiese
+ Version 0.0.8:
+ Removed EZUSB Firmware. First Stage Firmwaredownload is now done by tascam-firmware downloader.
+ See:
+ http://usb-midi-fw.sourceforge.net/tascam-firmware.tar.gz
+
+2003-06-18 Karsten Wiese
+ Version 0.0.5:
+ changed to compile with kernel 2.4.21 and alsa 0.9.4
+
+2002-10-16 Karsten Wiese
+ Version 0.0.4:
+ compiles again with alsa-current.
+ USB_ISO_ASAP not used anymore (most of the time), instead
+ urb->start_frame is calculated here now, some calls inside usb-driver don't need to happen anymore.
+
+ To get the best out of this:
+ Disable APM-support in the kernel as APM-BIOS calls (once each second) hard disable interrupt for many precious milliseconds.
+ This helped me much on my slowish PII 400 & PIII 500.
+ ACPI yet untested but might cause the same bad behaviour.
+ Use a kernel with lowlatency and preemptiv patches applied.
+ To autoload snd-usb-midi append a line
+ post-install snd-usb-us428 modprobe snd-usb-midi
+ to /etc/modules.conf.
+
+ known problems:
+ sliders, knobs, lights not yet handled except MASTER Volume slider.
+ "pcm -c 2" doesn't work. "pcm -c 2 -m direct_interleaved" does.
+ KDE3: "Enable full duplex operation" deadlocks.
+
+
+2002-08-31 Karsten Wiese
+ Version 0.0.3: audio also simplex;
+ simplifying: iso urbs only 1 packet, melted structs.
+ ASYNC_UNLINK not used anymore: no more crashes so far.....
+ for alsa 0.9 rc3.
+
+2002-08-09 Karsten Wiese
+ Version 0.0.2: midi works with snd-usb-midi, audio (only fullduplex now) with i.e. bristol.
+ The firmware has been sniffed from win2k us-428 driver 3.09.

+/* USX2Y "rawusb" aka hwdep_pcm implementation
+
+ Its usb's unableness to atomically handle power of 2 period sized data chuncs
+ at standard samplerates,
+ what led to this part of the usx2y module:
+ It provides the alsa kernel half of the usx2y-alsa-jack driver pair.
+ The pair uses a hardware dependent alsa-device for mmaped pcm transport.
+ Advantage achieved:
+ The usb_hc moves pcm data from/into memory via DMA.
+ That memory is mmaped by jack's usx2y driver.
+ Jack's usx2y driver is the first/last to read/write pcm data.
+ Read/write is a combination of power of 2 period shaping and
+ float/int conversation.
+ Compared to mainline alsa/jack we leave out power of 2 period shaping inside
+ snd-usb-usx2y which needs memcpy() and additional buffers.
+ As a side effect possible unwanted pcm-data coruption resulting of
+ standard alsa's snd-usb-usx2y period shaping scheme falls away.
+ Result is sane jack operation at buffering schemes down to 128frames,
+ 2 periods.
+ plain usx2y alsa mode is able to achieve 64frames, 4periods, but only at the
+ cost of easier triggered i.e. aeolus xruns (128 or 256frames,
+ 2periods works but is useless cause of crackling).
+
+ This is a first "proof of concept" implementation.
+ Later, functionalities should migrate to more appropriate places:
+ Userland:
+ - The jackd could mmap its float-pcm buffers directly from alsa-lib.
+ - alsa-lib could provide power of 2 period sized shaping combined with int/float
+ conversation.
+ Currently the usx2y jack driver provides above 2 services.
+ Kernel:
+ - rawusb dma pcm buffer transport should go to snd-usb-lib, so also snd-usb-audio
+ devices can use it.
+ Currently rawusb dma pcm buffer transport (this file) is only available to snd-usb-usx2y.
