|
|
* ????: Did I break MIDI support?
|
|
*
|
|
* History:
|
|
*
|
|
* Rolf Fokkens (Dec 20 1998): ES188x recording level support on a per
|
|
* fokkensr@vertis.nl input basis.
|
|
* (Dec 24 1998): Recognition of ES1788, ES1887, ES1888,
|
|
* ES1868, ES1869 and ES1878. Could be used for
|
|
* specific handling in the future. All except
|
|
* ES1887 and ES1888 and ES688 are handled like
|
|
* ES1688.
|
|
* (Dec 27 1998): RECLEV for all (?) ES1688+ chips. ES188x now
|
|
* have the "Dec 20" support + RECLEV
|
|
* (Jan 2 1999): Preparation for Full Duplex. This means
|
|
* Audio 2 is now used for playback when dma16
|
|
* is specified. The next step would be to use
|
|
* Audio 1 and Audio 2 at the same time.
|
|
* (Jan 9 1999): Put all ESS stuff into sb_ess.[ch], this
|
|
* includes both the ESS stuff that has been in
|
|
* sb_*[ch] before I touched it and the ESS support
|
|
* I added later
|
|
* (Jan 23 1999): Full Duplex seems to work. I wrote a small
|
|
* test proggy which works OK. Haven't found
|
|
* any applications to test it though. So why did
|
|
* I bother to create it anyway?? :) Just for
|
|
* fun.
|
|
* (May 2 1999): I tried to be too smart by "introducing"
|
|
* ess_calc_best_speed (). The idea was that two
|
|
* dividers could be used to setup a samplerate,
|
|
* ess_calc_best_speed () would choose the best.
|
|
* This works for playback, but results in
|
|
* recording problems for high samplerates. I
|
|
* fixed this by removing ess_calc_best_speed ()
|
|
* and just doing what the documentation says.
|
|
* Andy Sloane (Jun 4 1999): Stole some code from ALSA to fix the playback
|
|
* andy@guildsoftware.com speed on ES1869, ES1879, ES1887, and ES1888.
|
|
* 1879's were previously ignored by this driver;
|
|
* added (untested) support for those.
|
|
* Cvetan Ivanov (Oct 27 1999): Fixed ess_dsp_init to call ess_set_dma_hw for
|
|
* zezo@inet.bg _ALL_ ESS models, not only ES1887
|
|
*
|
|
* This files contains ESS chip specifics. It's based on the existing ESS
|
|
* handling as it resided in sb_common.c, sb_mixer.c and sb_audio.c. This
|
|
* file adds features like:
|
|
* - Chip Identification (as shown in /proc/sound)
|
|
* - RECLEV support for ES1688 and later
|
|
* - 6 bits playback level support chips later than ES1688
|
|
* - Recording level support on a per-device basis for ES1887
|
|
* - Full-Duplex for ES1887
|
|
*
|
|
* Full duplex is enabled by specifying dma16. While the normal dma must
|
|
* be one of 0, 1 or 3, dma16 can be one of 0, 1, 3 or 5. DMA 5 is a 16 bit
|
|
* DMA channel, while the others are 8 bit..
|
|
*
|
|
* ESS detection isn't full proof (yet). If it fails an additional module
|
|
* parameter esstype can be specified to be one of the following:
|
|
* -1, 0, 688, 1688, 1868, 1869, 1788, 1887, 1888
|
|
* -1 means: mimic 2.0 behaviour,
|
|
* 0 means: auto detect.
|
|
* others: explicitly specify chip
|
|
* -1 is default, cause auto detect still doesn't work.

/*
|
|
* About the documentation
|
|
*
|
|
* I don't know if the chips all are OK, but the documentation is buggy. 'cause
|
|
* I don't have all the cips myself, there's a lot I cannot verify. I'll try to
|
|
* keep track of my latest insights about his here. If you have additional info,
|
|
* please enlighten me (fokkensr@vertis.nl)!
|
|
*
|
|
* I had the impression that ES1688 also has 6 bit master volume control. The
|
|
* documentation about ES1888 (rev C, october '95) claims that ES1888 has
|
|
* the following features ES1688 doesn't have:
|
|
* - 6 bit master volume
|
|
* - Full Duplex
|
|
* So ES1688 apparently doesn't have 6 bit master volume control, but the
|
|
* ES1688 does have RECLEV control. Makes me wonder: does ES688 have it too?
|
|
* Without RECLEV ES688 won't be much fun I guess.
|
|
*
|
|
* From the ES1888 (rev C, october '95) documentation I got the impression
|
|
* that registers 0x68 to 0x6e don't exist which means: no recording volume
|
|
* controls. To my surprise the ES888 documentation (1/14/96) claims that
|
|
* ES888 does have these record mixer registers, but that ES1888 doesn't have
|
|
* 0x69 and 0x6b. So the rest should be there.
|
|
*
|
|
* I'm trying to get ES1887 Full Duplex. Audio 2 is playback only, while Audio 2
|
|
* is both record and playback. I think I should use Audio 2 for all playback.
|
|
*
|
|
* The documentation is an adventure: it's close but not fully accurate. I
|
|
* found out that after a reset some registers are *NOT* reset, though the
|
|
* docs say the would be. Interesting ones are 0x7f, 0x7d and 0x7a. They are
|
|
* related to the Audio 2 channel. I also was surprised about the consequences
|
|
* of writing 0x00 to 0x7f (which should be done by reset): The ES1887 moves
|
|
* into ES1888 mode. This means that it claims IRQ 11, which happens to be my
|
|
* ISDN adapter. Needless to say it no longer worked. I now understand why
|
|
* after rebooting 0x7f already was 0x05, the value of my choice: the BIOS
|
|
* did it.
|
|
*
|
|
* Oh, and this is another trap: in ES1887 docs mixer register 0x70 is
|
|
* described as if it's exactly the same as register 0xa1. This is *NOT* true.
|
|
* The description of 0x70 in ES1869 docs is accurate however.
|
|
* Well, the assumption about ES1869 was wrong: register 0x70 is very much
|
|
* like register 0xa1, except that bit 7 is always 1, whatever you want
|
|
* it to be.
|
|
*
|
|
* When using audio 2 mixer register 0x72 seems te be meaningless. Only 0xa2
|
|
* has effect.
|
|
*
|
|
* Software reset not being able to reset all registers is great! Especially
|
|
* the fact that register 0x78 isn't reset is great when you wanna change back
|
|
* to single dma operation (simplex): audio 2 is still operational, and uses
|
|
* the same dma as audio 1: your ess changes into a funny echo machine.
|
|
*
|
|
* Received the news that ES1688 is detected as a ES1788. Did some thinking:
|
|
* the ES1887 detection scheme suggests in step 2 to try if bit 3 of register
|
|
* 0x64 can be changed. This is inaccurate, first I inverted the * check: "If
|
|
* can be modified, it's a 1688", which lead to a correct detection
|
|
* of my ES1887. It resulted however in bad detection of 1688 (reported by mail)
|
|
* and 1868 (if no PnP detection first): they result in a 1788 being detected.
|
|
* I don't have docs on 1688, but I do have docs on 1868: The documentation is
|
|
* probably inaccurate in the fact that I should check bit 2, not bit 3. This
|
|
* is what I do now.

/*
|
|
* About recognition of ESS chips
|
|
*
|
|
* The distinction of ES688, ES1688, ES1788, ES1887 and ES1888 is described in
|
|
* a (preliminary ??) datasheet on ES1887. Its aim is to identify ES1887, but
|
|
* during detection the text claims that "this chip may be ..." when a step
|
|
* fails. This scheme is used to distinct between the above chips.
|
|
* It appears however that some PnP chips like ES1868 are recognized as ES1788
|
|
* by the ES1887 detection scheme. These PnP chips can be detected in another
|
|
* way however: ES1868, ES1869 and ES1878 can be recognized (full proof I think)
|
|
* by repeatedly reading mixer register 0x40. This is done by ess_identify in
|
|
* sb_common.c.
|
|
* This results in the following detection steps:
|
|
* - distinct between ES688 and ES1688+ (as always done in this driver)
|
|
* if ES688 we're ready
|
|
* - try to detect ES1868, ES1869 or ES1878
|
|
* if successful we're ready
|
|
* - try to detect ES1888, ES1887 or ES1788
|
|
* if successful we're ready
|
|
* - Dunno. Must be 1688. Will do in general
|
|
*
|
|
* About RECLEV support:
|
|
*
|
|
* The existing ES1688 support didn't take care of the ES1688+ recording
|
|
* levels very well. Whenever a device was selected (recmask) for recording
|
|
* its recording level was loud, and it couldn't be changed. The fact that
|
|
* internal register 0xb4 could take care of RECLEV, didn't work meaning until
|
|
* its value was restored every time the chip was reset; this reset the
|
|
* value of 0xb4 too. I guess that's what 4front also had (have?) trouble with.
|
|
*
|
|
* About ES1887 support:
|
|
*
|
|
* The ES1887 has separate registers to control the recording levels, for all
|
|
* inputs. The ES1887 specific software makes these levels the same as their
|
|
* corresponding playback levels, unless recmask says they aren't recorded. In
|
|
* the latter case the recording volumes are 0.
|
|
* Now recording levels of inputs can be controlled, by changing the playback
|
|
* levels. Furthermore several devices can be recorded together (which is not
|
|
* possible with the ES1688).
|
|
* Besides the separate recording level control for each input, the common
|
|
* recording level can also be controlled by RECLEV as described above.
|
|
*
|
|
* Not only ES1887 have this recording mixer. I know the following from the
|
|
* documentation:
|
|
* ES688 no
|
|
* ES1688 no
|
|
* ES1868 no
|
|
* ES1869 yes
|
|
* ES1878 no
|
|
* ES1879 yes
|
|
* ES1888 no/yes Contradicting documentation; most recent: yes
|
|
* ES1946 yes This is a PCI chip; not handled by this driver
