About 2-6 megabytes of memory are associated with 66 * the chip. Most of this goes to video frame buffers, but some is used for 67 * audio buffering 68 * 69 * Unlike most PCI audio chips, the Neomagic chip does not rely on DMA. 70 * Instead, the chip allows you to carve out two ring buffers out of its 71 * memory. However you carve this and how much you can carve seems to be 72 * voodoo. The algorithm is in nm_init. 73 * 74 * Most Neomagic audio chips use the AC-97 codec interface. However, there 75 * seem to be a select few chips 256AV chips that do not support AC-97. 76 * This driver does not support them but there are rumors that it 77 * might work with wss isa drivers. This might require some playing around 78 * with your BIOS. 79 * 80 * The Neomagic 256 AV/ZX have 2 PCI I/O region descriptors. Both of 81 * them describe a memory region. The frame buffer is the first region 82 * and the register set is the secodn region. 83 * 84 * The register manipulation logic is taken from the Linux driver, 85 * which is in the public domain. 86 * 87 * The Neomagic is even nice enough to map the AC-97 codec registers into 88 * the register space to allow direct manipulation. Watch out, accessing 89 * AC-97 registers on the Neomagic requires great delicateness, otherwise 90 * the thing will hang the PCI bus, rendering your system frozen. 91 * 92 * For one, it seems the Neomagic status register that reports AC-97 93 * readiness should NOT be polled more often than once each 1ms. 94 * 95 * Also, writes to the AC-97 register space may take order 40us to 96 * complete. 97 * 98 * Unlike many sound engines, the Neomagic does not support (as far as 99 * we know :) the notion of interrupting every n bytes transferred, 100 * unlike many DMA engines. Instead, it allows you to specify one 101 * location in each ring buffer (called the watermark). When the chip 102 * passes that location while playing, it signals an interrupt. 103 * 104 * The ring buffer size is currently 16k. That is about 100ms of audio 105 * at 44.1kHz/stero/16 bit. However, to keep the buffer full, interrupts 106 * are generated more often than that, so 20-40 interrupts per second 107 * should not be unexpected. Increasing BUFFSIZE should help minimize 108 * of glitches due to drivers that spend to much time looping at high 109 * privelege levels as well as the impact of badly written audio 110 * interface clients. 111 * 112 * TO-DO list: 113 * Figure out interaction with video stuff (look at Xfree86 driver?) 114 * 115 * Figure out how to shrink that huge table neo-coeff.h 116 */ 117 118 #define NM_BUFFSIZE 16384 119 120 /* device private data */ 121 struct neo_softc { 122 struct device dev;
