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