|
*
|
|
*
|
|
* Module command line parameters:
|
|
* lineout if 1 the LINE jack is used as an output instead of an input.
|
|
* LINE then contains the unmixed dsp output. This can be used
|
|
* to make the card a four channel one: use dsp to output two
|
|
* channels to LINE and dac to output the other two channels to
|
|
* SPKR. Set the mixer to only output synth to SPKR.
|
|
* micbias sets the +5V bias to the mic if using an electretmic.
|
|
*
|
|
*
|
|
* Note: sync mode is not yet supported (i.e. running dsp and dac from the same
|
|
* clock source)
|
|
*
|
|
* Supported devices:
|
|
* /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
|
|
* /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
|
|
* /dev/dsp1 additional DAC, like /dev/dsp, but output only,
|
|
* only 5512, 11025, 22050 and 44100 samples/s,
|
|
* outputs to mixer "SYNTH" setting
|
|
* /dev/midi simple MIDI UART interface, no ioctl
|
|
*
|
|
* NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed
|
|
* to be done in software. That is what /dev/dac is for. By now (Q2 1998)
|
|
* there are several MIDI to PCM (WAV) packages, one of them is timidity.
|
|
*
|
|
* Revision history
|
|
* 26.03.1998 0.1 Initial release
|
|
* 31.03.1998 0.2 Fix bug in GETOSPACE
|
|
* 04.04.1998 0.3 Make it work (again) under 2.0.33
|
|
* Fix mixer write operation not returning the actual
|
|
* settings
|
|
* 05.04.1998 0.4 First attempt at using the new PCI stuff
|
|
* 29.04.1998 0.5 Fix hang when ^C is pressed on amp
|
|
* 07.05.1998 0.6 Don't double lock around stop_*() in *_release()
|
|
* 10.05.1998 0.7 First stab at a simple midi interface (no bells&whistles)
|
|
* 14.05.1998 0.8 Don't allow excessive interrupt rates
|
|
* 08.06.1998 0.9 First release using Alan Cox' soundcore instead of
|
|
* miscdevice
|
|
* 05.07.1998 0.10 Fixed the driver to correctly maintin OSS style volume
|
|
* settings (not sure if this should be standard)
|
|
* Fixed many references: f_flags should be f_mode
|
|
* -- Gerald Britton <gbritton@mit.edu>
|
|
* 03.08.1998 0.11 Now mixer behaviour can basically be selected between
|
|
* "OSS documented" and "OSS actual" behaviour
|
|
* Fixed mixer table thanks to Hakan.Lennestal@lu.erisoft.se
|
|
* On module startup, set DAC2 to 11kSPS instead of 5.5kSPS,
|
|
* as it produces an annoying ssssh in the lower sampling rate
|
|
* Do not include modversions.h
|
|
* 22.08.1998 0.12 Mixer registers actually have 5 instead of 4 bits
|
|
* pointed out by Itai Nahshon
|
|
* 31.08.1998 0.13 Fix realplayer problems - dac.count issues
|
|
* 08.10.1998 0.14 Joystick support fixed
|
|
* -- Oliver Neukum <c188@org.chemie.uni-muenchen.de>
|
|
* 10.12.1998 0.15 Fix drain_dac trying to wait on not yet initialized DMA
|
|
* 16.12.1998 0.16 Don't wake up app until there are fragsize bytes to read/write
|
|
* 06.01.1999 0.17 remove the silly SA_INTERRUPT flag.
|
|
* hopefully killed the egcs section type conflict
|
|
* 12.03.1999 0.18 cinfo.blocks should be reset after GETxPTR ioctl.
|
|
* reported by Johan Maes <joma@telindus.be>
|
|
* 22.03.1999 0.19 return EAGAIN instead of EBUSY when O_NONBLOCK
|
|
* read/write cannot be executed
|
|
* 07.04.1999 0.20 implemented the following ioctl's: SOUND_PCM_READ_RATE,
|
|
* SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
|
|
* Alpha fixes reported by Peter Jones <pjones@redhat.com>
|
|
* Note: joystick address handling might still be wrong on archs
|
|
* other than i386
|
|
* 10.05.1999 0.21 Added support for an electret mic for SB PCI64
|
|
* to the Linux kernel sound driver. This mod also straighten
|
|
* out the question marks around the mic impedance setting
|
|
* (micz). From Kim.Berts@fisub.mail.abb.com
|
|
* 11.05.1999 0.22 Implemented the IMIX call to mute recording monitor.
|
|
* Guenter Geiger <geiger@epy.co.at>
|
|
* 15.06.1999 0.23 Fix bad allocation bug.
|
|
* Thanks to Deti Fliegl <fliegl@in.tum.de>
|
|
* 28.06.1999 0.24 Add pci_set_master
|
|
* 02.08.1999 0.25 Added workaround for the "phantom write" bug first
|
|
* documented by Dave Sharpless from Anchor Games
|
|
* 03.08.1999 0.26 adapt to Linus' new __setup/__initcall
|
|
* added kernel command line option "es1370=joystick[,lineout[,micbias]]"
|
|
* removed CONFIG_SOUND_ES1370_JOYPORT_BOOT kludge
|
|
* 12.08.1999 0.27 module_init/__setup fixes
|
|
* 19.08.1999 0.28 SOUND_MIXER_IMIX fixes, reported by Gianluca <gialluca@mail.tiscalinet.it>
|
|
* 31.08.1999 0.29 add spin_lock_init
|
|
* replaced current->state = x with set_current_state(x)
|
|
* 03.09.1999 0.30 change read semantics for MIDI to match
|
|
* OSS more closely; remove possible wakeup race
|
|
* 28.10.1999 0.31 More waitqueue races fixed
|
|
* 08.01.2000 0.32 Prevent some ioctl's from returning bad count values on underrun/overrun;
|
|
* Tim Janik's BSE (Bedevilled Sound Engine) found this
|
|
* 07.02.2000 0.33 Use pci_alloc_consistent and pci_register_driver
|
|
* 21.11.2000 0.34 Initialize dma buffers in poll, otherwise poll may return a bogus mask
|
|
* 12.12.2000 0.35 More dma buffer initializations, patch from
|
|
* Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
|
|
* 07.01.2001 0.36 Timeout change in wrcodec as requested by Frank Klemm <pfk@fuchs.offl.uni-jena.de>
|
|
* 31.01.2001 0.37 Register/Unregister gameport
|
|
* Fix SETTRIGGER non OSS API conformity
|
|
* 03.01.2003 0.38 open_mode fixes from Georg Acher <acher@in.tum.de>
|
|
*
|
|
* some important things missing in Ensoniq documentation:
|
|
*
|
|
* Experimental PCLKDIV results: play the same waveforms on both DAC1 and DAC2
|
|
* and vary PCLKDIV to obtain zero beat.
|
|
* 5512sps: 254
|
|
* 44100sps: 30
|
|
* seems to be fs = 1411200/(PCLKDIV+2)
|
|
*
|
|
* should find out when curr_sample_ct is cleared and
|
|
* where exactly the CCB fetches data
|
|
*
|
|
* The card uses a 22.5792 MHz crystal.
|
|
* The LINEIN jack may be converted to an AOUT jack by
|
|
* setting pin 47 (XCTL0) of the ES1370 to high.
|
|
* Pin 48 (XCTL1) of the ES1370 sets the +5V bias for an electretmic
|
