88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * The driver is primarily targeted at providing audio support for
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * those systems which use the Uli M1575 audio core.
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * The M1575 audio core, in AC'97 controller mode, has independent
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * channels for PCM in, PCM out, mic in, modem in, and modem out.
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * The AC'97 controller is a PCI bus master with scatter/gather
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * support. Each channel has a DMA engine. Currently, we use only
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * the PCM in and PCM out channels. Each DMA engine uses one buffer
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * descriptor list. And the buffer descriptor list is an array of up
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * to 32 entries, each of which describes a data buffer. Each entry
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * contains a pointer to a data buffer, control bits, and the length
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * of the buffer being pointed to, where the length is expressed as
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * the number of samples. This, combined with the 16-bit sample size,
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * gives the actual physical length of the buffer.
88447a05f537aabe9a1bc3d5313f22581ec992a7Garrett D'Amore * This driver depends on the drv/audio, misc/ac97
