24 *
25 * Module command line parameters:
26 * lineout if 1 the LINE jack is used as an output instead of an input.
27 * LINE then contains the unmixed dsp output. This can be used
28 * to make the card a four channel one: use dsp to output two
29 * channels to LINE and dac to output the other two channels to
30 * SPKR. Set the mixer to only output synth to SPKR.
31 * micbias sets the +5V bias to the mic if using an electretmic.
32 *
33 *
34 * Note: sync mode is not yet supported (i.e. running dsp and dac from the same
35 * clock source)
36 *
37 * Supported devices:
38 * /dev/dsp standard /dev/dsp device, (mostly) OSS compatible
39 * /dev/mixer standard /dev/mixer device, (mostly) OSS compatible
40 * /dev/dsp1 additional DAC, like /dev/dsp, but output only,
41 * only 5512, 11025, 22050 and 44100 samples/s,
42 * outputs to mixer "SYNTH" setting
43 * /dev/midi simple MIDI UART interface, no ioctl
44 *
45 * NOTE: the card does not have any FM/Wavetable synthesizer, it is supposed
46 * to be done in software. That is what /dev/dac is for. By now (Q2 1998)
47 * there are several MIDI to PCM (WAV) packages, one of them is timidity.
48 *
49 * Revision history
50 * 26.03.1998 0.1 Initial release
51 * 31.03.1998 0.2 Fix bug in GETOSPACE
52 * 04.04.1998 0.3 Make it work (again) under 2.0.33
53 * Fix mixer write operation not returning the actual
54 * settings
55 * 05.04.1998 0.4 First attempt at using the new PCI stuff
56 * 29.04.1998 0.5 Fix hang when ^C is pressed on amp
57 * 07.05.1998 0.6 Don't double lock around stop_*() in *_release()
58 * 10.05.1998 0.7 First stab at a simple midi interface (no bells&whistles)
59 * 14.05.1998 0.8 Don't allow excessive interrupt rates
60 * 08.06.1998 0.9 First release using Alan Cox' soundcore instead of
61 * miscdevice
62 * 05.07.1998 0.10 Fixed the driver to correctly maintin OSS style volume
63 * settings (not sure if this should be standard)
64 * Fixed many references: f_flags should be f_mode
65 * -- Gerald Britton <gbritton@mit.edu>
66 * 03.08.1998 0.11 Now mixer behaviour can basically be selected between
67 * "OSS documented" and "OSS actual" behaviour
68 * Fixed mixer table thanks to Hakan.Lennestal@lu.erisoft.se
69 * On module startup, set DAC2 to 11kSPS instead of 5.5kSPS,
70 * as it produces an annoying ssssh in the lower sampling rate
71 * Do not include modversions.h
72 * 22.08.1998 0.12 Mixer registers actually have 5 instead of 4 bits
73 * pointed out by Itai Nahshon
74 * 31.08.1998 0.13 Fix realplayer problems - dac.count issues
75 * 08.10.1998 0.14 Joystick support fixed
76 * -- Oliver Neukum <c188@org.chemie.uni-muenchen.de>
77 * 10.12.1998 0.15 Fix drain_dac trying to wait on not yet initialized DMA
78 * 16.12.1998 0.16 Don't wake up app until there are fragsize bytes to read/write
79 * 06.01.1999 0.17 remove the silly SA_INTERRUPT flag.
80 * hopefully killed the egcs section type conflict
81 * 12.03.1999 0.18 cinfo.blocks should be reset after GETxPTR ioctl.
82 * reported by Johan Maes <joma@telindus.be>
83 * 22.03.1999 0.19 return EAGAIN instead of EBUSY when O_NONBLOCK
84 * read/write cannot be executed
85 * 07.04.1999 0.20 implemented the following ioctl's: SOUND_PCM_READ_RATE,
86 * SOUND_PCM_READ_CHANNELS, SOUND_PCM_READ_BITS;
87 * Alpha fixes reported by Peter Jones <pjones@redhat.com>
88 * Note: joystick address handling might still be wrong on archs
89 * other than i386
90 * 10.05.1999 0.21 Added support for an electret mic for SB PCI64
91 * to the Linux kernel sound driver. This mod also straighten
92 * out the question marks around the mic impedance setting
93 * (micz). From Kim.Berts@fisub.mail.abb.com
94 * 11.05.1999 0.22 Implemented the IMIX call to mute recording monitor.
95 * Guenter Geiger <geiger@epy.co.at>
96 * 15.06.1999 0.23 Fix bad allocation bug.
97 * Thanks to Deti Fliegl <fliegl@in.tum.de>
98 * 28.06.1999 0.24 Add pci_set_master
99 * 02.08.1999 0.25 Added workaround for the "phantom write" bug first
100 * documented by Dave Sharpless from Anchor Games
101 * 03.08.1999 0.26 adapt to Linus' new __setup/__initcall
102 * added kernel command line option "es1370=joystick[,lineout[,micbias]]"
103 * removed CONFIG_SOUND_ES1370_JOYPORT_BOOT kludge
104 * 12.08.1999 0.27 module_init/__setup fixes
105 * 19.08.1999 0.28 SOUND_MIXER_IMIX fixes, reported by Gianluca <gialluca@mail.tiscalinet.it>
106 * 31.08.1999 0.29 add spin_lock_init
107 * replaced current->state = x with set_current_state(x)
108 * 03.09.1999 0.30 change read semantics for MIDI to match
109 * OSS more closely; remove possible wakeup race
110 * 28.10.1999 0.31 More waitqueue races fixed
111 * 08.01.2000 0.32 Prevent some ioctl's from returning bad count values on underrun/overrun;
112 * Tim Janik's BSE (Bedevilled Sound Engine) found this
113 * 07.02.2000 0.33 Use pci_alloc_consistent and pci_register_driver
114 * 21.11.2000 0.34 Initialize dma buffers in poll, otherwise poll may return a bogus mask
115 * 12.12.2000 0.35 More dma buffer initializations, patch from
116 * Tjeerd Mulder <tjeerd.mulder@fujitsu-siemens.com>
117 * 07.01.2001 0.36 Timeout change in wrcodec as requested by Frank Klemm <pfk@fuchs.offl.uni-jena.de>
118 * 31.01.2001 0.37 Register/Unregister gameport
119 * Fix SETTRIGGER non OSS API conformity
120 * 03.01.2003 0.38 open_mode fixes from Georg Acher <acher@in.tum.de>
121 *
122 * some important things missing in Ensoniq documentation:
123 *
124 * Experimental PCLKDIV results: play the same waveforms on both DAC1 and DAC2
125 * and vary PCLKDIV to obtain zero beat.
126 * 5512sps: 254
127 * 44100sps: 30
128 * seems to be fs = 1411200/(PCLKDIV+2)
129 *
130 * should find out when curr_sample_ct is cleared and
131 * where exactly the CCB fetches data
132 *
133 * The card uses a 22.5792 MHz crystal.
134 * The LINEIN jack may be converted to an AOUT jack by
135 * setting pin 47 (XCTL0) of the ES1370 to high.
136 * Pin 48 (XCTL1) of the ES1370 sets the +5V bias for an electretmic
137 *
