- * 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.
