| 28 | * Notes from Zach Brown about the driver code |
| 29 | * |
| 30 | * Hardware Description |
| 31 | * |
| 32 | * A working Maestro setup contains the Maestro chip wired to a |
| 33 | * codec or 2. In the Maestro we have the APUs, the ASSP, and the |
| 34 | * Wavecache. The APUs can be though of as virtual audio routing |
| 35 | * channels. They can take data from a number of sources and perform |
| 36 | * basic encodings of the data. The wavecache is a storehouse for |
| 37 | * PCM data. Typically it deals with PCI and interracts with the |
| 38 | * APUs. The ASSP is a wacky DSP like device that ESS is loth |
| 39 | * to release docs on. Thankfully it isn't required on the Maestro |
| 40 | * until you start doing insane things like FM emulation and surround |
| 41 | * encoding. The codecs are almost always AC-97 compliant codecs, |
| 42 | * but it appears that early Maestros may have had PT101 (an ESS |
| 43 | * part?) wired to them. The only real difference in the Maestro |
| 44 | * families is external goop like docking capability, memory for |
| 45 | * the ASSP, and initialization differences. |
| 46 | * |
| 47 | * Driver Operation |
| 48 | * |
| 49 | * We only drive the APU/Wavecache as typical DACs and drive the |
| 50 | * mixers in the codecs. There are 64 APUs. We assign 6 to each |
| 51 | * /dev/dsp? device. 2 channels for output, and 4 channels for |
| 52 | * input. |
| 53 | * |
| 54 | * Each APU can do a number of things, but we only really use |
| 55 | * 3 basic functions. For playback we use them to convert PCM |
| 56 | * data fetched over PCI by the wavecahche into analog data that |
| 57 | * is handed to the codec. One APU for mono, and a pair for stereo. |
| 58 | * When in stereo, the combination of smarts in the APU and Wavecache |
| 59 | * decide which wavecache gets the left or right channel. |
| 60 | * |
| 61 | * For record we still use the old overly mono system. For each in |
| 62 | * coming channel the data comes in from the codec, through a 'input' |
| 63 | * APU, through another rate converter APU, and then into memory via |
| 64 | * the wavecache and PCI. If its stereo, we mash it back into LRLR in |
| 65 | * software. The pass between the 2 APUs is supposedly what requires us |
| 66 | * to have a 512 byte buffer sitting around in wavecache/memory. |
| 67 | * |
| 68 | * The wavecache makes our life even more fun. First off, it can |
| 69 | * only address the first 28 bits of PCI address space, making it |
| 70 | * useless on quite a few architectures. Secondly, its insane. |
| 71 | * It claims to fetch from 4 regions of PCI space, each 4 meg in length. |
| 72 | * But that doesn't really work. You can only use 1 region. So all our |
| 73 | * allocations have to be in 4meg of each other. Booo. Hiss. |
| 74 | * So we have a module parameter, dsps_order, that is the order of |
| 75 | * the number of dsps to provide. All their buffer space is allocated |
| 76 | * on open time. The sonicvibes OSS routines we inherited really want |
| 77 | * power of 2 buffers, so we have all those next to each other, then |
| 78 | * 512 byte regions for the recording wavecaches. This ends up |
| 79 | * wasting quite a bit of memory. The only fixes I can see would be |
| 80 | * getting a kernel allocator that could work in zones, or figuring out |
| 81 | * just how to coerce the WP into doing what we want. |
| 82 | * |
| 83 | * The indirection of the various registers means we have to spinlock |
| 84 | * nearly all register accesses. We have the main register indirection |
| 85 | * like the wave cache, maestro registers, etc. Then we have beasts |
| 86 | * like the APU interface that is indirect registers gotten at through |
| 87 | * the main maestro indirection. Ouch. We spinlock around the actual |
| 88 | * ports on a per card basis. This means spinlock activity at each IO |
| 89 | * operation, but the only IO operation clusters are in non critical |
| 90 | * paths and it makes the code far easier to follow. Interrupts are |
| 91 | * blocked while holding the locks because the int handler has to |
| 92 | * get at some of them :(. The mixer interface doesn't, however. |
| 93 | * We also have an OSS state lock that is thrown around in a few |
| 94 | * places. |
