13 * Rolf Fokkens (Dec 20 1998): ES188x recording level support on a per
14 * fokkensr@vertis.nl input basis.
15 * (Dec 24 1998): Recognition of ES1788, ES1887, ES1888,
16 * ES1868, ES1869 and ES1878. Could be used for
17 * specific handling in the future. All except
18 * ES1887 and ES1888 and ES688 are handled like
20 * (Dec 27 1998): RECLEV for all (?) ES1688+ chips. ES188x now
21 * have the "Dec 20" support + RECLEV
22 * (Jan 2 1999): Preparation for Full Duplex. This means
23 * Audio 2 is now used for playback when dma16
24 * is specified. The next step would be to use
25 * Audio 1 and Audio 2 at the same time.
26 * (Jan 9 1999): Put all ESS stuff into sb_ess.[ch], this
27 * includes both the ESS stuff that has been in
28 * sb_*[ch] before I touched it and the ESS support
30 * (Jan 23 1999): Full Duplex seems to work. I wrote a small
31 * test proggy which works OK. Haven't found
32 * any applications to test it though. So why did
33 * I bother to create it anyway?? :) Just for
35 * (May 2 1999): I tried to be too smart by "introducing"
36 * ess_calc_best_speed (). The idea was that two
37 * dividers could be used to setup a samplerate,
38 * ess_calc_best_speed () would choose the best.
39 * This works for playback, but results in
40 * recording problems for high samplerates. I
41 * fixed this by removing ess_calc_best_speed ()
42 * and just doing what the documentation says.
43 * Andy Sloane (Jun 4 1999): Stole some code from ALSA to fix the playback
44 * andy@guildsoftware.com speed on ES1869, ES1879, ES1887, and ES1888.
45 * 1879's were previously ignored by this driver;
46 * added (untested) support for those.
47 * Cvetan Ivanov (Oct 27 1999): Fixed ess_dsp_init to call ess_set_dma_hw for
48 * zezo@inet.bg _ALL_ ESS models, not only ES1887
50 * This files contains ESS chip specifics. It's based on the existing ESS
51 * handling as it resided in sb_common.c, sb_mixer.c and sb_audio.c. This
52 * file adds features like:
53 * - Chip Identification (as shown in /proc/sound)
54 * - RECLEV support for ES1688 and later
55 * - 6 bits playback level support chips later than ES1688
56 * - Recording level support on a per-device basis for ES1887
57 * - Full-Duplex for ES1887
59 * Full duplex is enabled by specifying dma16. While the normal dma must
60 * be one of 0, 1 or 3, dma16 can be one of 0, 1, 3 or 5. DMA 5 is a 16 bit
61 * DMA channel, while the others are 8 bit..
63 * ESS detection isn't full proof (yet). If it fails an additional module
64 * parameter esstype can be specified to be one of the following:
65 * -1, 0, 688, 1688, 1868, 1869, 1788, 1887, 1888
66 * -1 means: mimic 2.0 behaviour,
67 * 0 means: auto detect.
68 * others: explicitly specify chip
69 * -1 is default, cause auto detect still doesn't work.
73 * About the documentation
75 * I don't know if the chips all are OK, but the documentation is buggy. 'cause
76 * I don't have all the cips myself, there's a lot I cannot verify. I'll try to
77 * keep track of my latest insights about his here. If you have additional info,
78 * please enlighten me (fokkensr@vertis.nl)!
80 * I had the impression that ES1688 also has 6 bit master volume control. The
81 * documentation about ES1888 (rev C, october '95) claims that ES1888 has
82 * the following features ES1688 doesn't have:
83 * - 6 bit master volume
85 * So ES1688 apparently doesn't have 6 bit master volume control, but the
86 * ES1688 does have RECLEV control. Makes me wonder: does ES688 have it too?
87 * Without RECLEV ES688 won't be much fun I guess.
89 * From the ES1888 (rev C, october '95) documentation I got the impression
90 * that registers 0x68 to 0x6e don't exist which means: no recording volume
91 * controls. To my surprise the ES888 documentation (1/14/96) claims that
92 * ES888 does have these record mixer registers, but that ES1888 doesn't have
93 * 0x69 and 0x6b. So the rest should be there.
95 * I'm trying to get ES1887 Full Duplex. Audio 2 is playback only, while Audio 2
96 * is both record and playback. I think I should use Audio 2 for all playback.
98 * The documentation is an adventure: it's close but not fully accurate. I
99 * found out that after a reset some registers are *NOT* reset, though the
100 * docs say the would be. Interresting ones are 0x7f, 0x7d and 0x7a. They are
101 * related to the Audio 2 channel. I also was suprised about the consequenses
102 * of writing 0x00 to 0x7f (which should be done by reset): The ES1887 moves
103 * into ES1888 mode. This means that it claims IRQ 11, which happens to be my
104 * ISDN adapter. Needless to say it no longer worked. I now understand why
105 * after rebooting 0x7f already was 0x05, the value of my choice: the BIOS
108 * Oh, and this is another trap: in ES1887 docs mixer register 0x70 is decribed
109 * as if it's exactly the same as register 0xa1. This is *NOT* true. The
110 * description of 0x70 in ES1869 docs is accurate however.
111 * Well, the assumption about ES1869 was wrong: register 0x70 is very much
112 * like register 0xa1, except that bit 7 is allways 1, whatever you want
115 * When using audio 2 mixer register 0x72 seems te be meaningless. Only 0xa2
118 * Software reset not being able to reset all registers is great! Especially
119 * the fact that register 0x78 isn't reset is great when you wanna change back
120 * to single dma operation (simplex): audio 2 is still operation, and uses the
121 * same dma as audio 1: your ess changes into a funny echo machine.
123 * Received the new that ES1688 is detected as a ES1788. Did some thinking:
124 * the ES1887 detection scheme suggests in step 2 to try if bit 3 of register
125 * 0x64 can be changed. This is inaccurate, first I inverted the * check: "If
126 * can be modified, it's a 1688", which lead to a correct detection
127 * of my ES1887. It resulted however in bad detection of 1688 (reported by mail)
128 * and 1868 (if no PnP detection first): they result in a 1788 being detected.
129 * I don't have docs on 1688, but I do have docs on 1868: The documentation is
130 * probably inaccurate in the fact that I should check bit 2, not bit 3. This
135 * About recognition of ESS chips
137 * The distinction of ES688, ES1688, ES1788, ES1887 and ES1888 is described in
138 * a (preliminary ??) datasheet on ES1887. It's aim is to identify ES1887, but
139 * during detection the text claims that "this chip may be ..." when a step
140 * fails. This scheme is used to distinct between the above chips.
141 * It appears however that some PnP chips like ES1868 are recognized as ES1788
142 * by the ES1887 detection scheme. These PnP chips can be detected in another
143 * way however: ES1868, ES1869 and ES1878 can be recognized (full proof I think)
144 * by repeatedly reading mixer register 0x40. This is done by ess_identify in
146 * This results in the following detection steps:
147 * - distinct between ES688 and ES1688+ (as always done in this driver)
148 * if ES688 we're ready
149 * - try to detect ES1868, ES1869 or ES1878
150 * if successful we're ready
151 * - try to detect ES1888, ES1887 or ES1788
152 * if successful we're ready
153 * - Dunno. Must be 1688. Will do in general
155 * About RECLEV support:
157 * The existing ES1688 support didn't take care of the ES1688+ recording
158 * levels very well. Whenever a device was selected (recmask) for recording
159 * it's recording level was loud, and it couldn't be changed. The fact that
160 * internal register 0xb4 could take care of RECLEV, didn't work meaning until
161 * it's value was restored every time the chip was reset; this reset the
162 * value of 0xb4 too. I guess that's what 4front also had (have?) trouble with.
164 * About ES1887 support:
166 * The ES1887 has separate registers to control the recording levels, for all
167 * inputs. The ES1887 specific software makes these levels the same as their
168 * corresponding playback levels, unless recmask says they aren't recorded. In
169 * the latter case the recording volumes are 0.
170 * Now recording levels of inputs can be controlled, by changing the playback
171 * levels. Futhermore several devices can be recorded together (which is not
172 * possible with the ES1688.
173 * Besides the separate recording level control for each input, the common
174 * recordig level can also be controlled by RECLEV as described above.
176 * Not only ES1887 have this recording mixer. I know the following from the
184 * ES1888 no/yes Contradicting documentation; most recent: yes
185 * ES1946 yes This is a PCI chip; not handled by this driver
