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.
