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.
