A pipe performs + audio transport - moving audio data to and from buffers on the host via + bus mastering. + + The inputs and outputs on the right represent input and output "busses." + A bus is a physical, real connection to the outside world. An example + of a bus would be the 1/4" analog connectors on the back of Layla or + an RCA S/PDIF connector. + + For most cards, there is a one-to-one correspondence between outputs + and busses; that is, each individual pipe is hard-wired to a single bus. + + Cards that work this way are Darla20, Gina20, Layla20, Darla24, Gina24, + Layla24, Mona, and Indigo. + + + Mia has a feature called "virtual outputs." + + + +-----------+ + record | |<----------------------------- Inputs + <-------| | | + PCI | Transport | | + bus | engine | \|/ + ------->| | +------+ +-------+ + play | |-->|vmixer|-->|monitor|-------> Outputs + +-----------+ +------+ | mixer | + +-------+ + + + Obviously, the difference here is the box labeled "vmixer." Vmixer is + short for "virtual output mixer." For Mia, pipes are *not* hard-wired + to a single bus; the vmixer lets you mix any pipe to any bus in any + combination. + + Note, however, that the left-hand side of the diagram is unchanged. + Transport works exactly the same way - the difference is in the mixer stage. + + + Pipes and busses are numbered starting at zero. + + + + Pipe index + ========== + + A number of calls in CEchoGals refer to a "pipe index". A pipe index is + a unique number for a pipe that unambiguously refers to a playback or record + pipe. Pipe indices are numbered starting with analog outputs, followed by + digital outputs, then analog inputs, then digital inputs. + + Take Gina24 as an example: + + Pipe index + + 0-7 Analog outputs (0 .. FirstDigitalBusOut-1) + 8-15 Digital outputs (FirstDigitalBusOut .. NumBussesOut-1) + 16-17 Analog inputs + 18-25 Digital inputs + + + You get the pipe index by calling CEchoGals::OpenAudio; the other transport + functions take the pipe index as a parameter. If you need a pipe index for + some other reason, use the handy Makepipe_index method. + + + Some calls take a CChannelMask parameter; CChannelMask is a handy way to + group pipe indices. + + + + Digital mode switch + =================== + + Some cards (right now, Gina24, Layla24, and Mona) have a Digital Mode Switch + or DMS. Cards with a DMS can be set to one of three mutually exclusive + digital modes: S/PDIF RCA, S/PDIF optical, or ADAT optical. + + This may create some confusion since ADAT optical is 8 channels wide and + S/PDIF is only two channels wide. Gina24, Layla24, and Mona handle this + by acting as if they always have 8 digital outs and ins. If you are in + either S/PDIF mode, the last 6 channels don't do anything - data sent + out these channels is thrown away and you will always record zeros. + + Note that with Gina24, Layla24, and Mona, sample rates above 50 kHz are + only available if you have the card configured for S/PDIF optical or S/PDIF + RCA. + + + + Double speed mode + ================= + + Some of the cards support 88.2 kHz and 96 kHz sampling (Darla24, Gina24, + Layla24, Mona, Mia, and Indigo). For these cards, the driver sometimes has + to worry about "double speed mode"; double speed mode applies whenever the + sampling rate is above 50 kHz. + + For instance, Mona and Layla24 support word clock sync. However, they + actually support two different word clock modes - single speed (below + 50 kHz) and double speed (above 50 kHz). The hardware detects if a single + or double speed word clock signal is present; the generic code uses that + information to determine which mode to use. + + The generic code takes care of all this for you. +*/ + + +#ifndef _ECHOAUDIO_H_ +#define _ECHOAUDIO_H_ + + +#include "echoaudio_dsp.h" + + + +/*********************************************************************** + + PCI configuration space + +***********************************************************************/ + +/* + * PCI vendor ID and device IDs for the hardware + */ +#define VENDOR_ID 0x1057 +#define DEVICE_ID_56301 0x1801 +#define DEVICE_ID_56361 0x3410 +#define SUBVENDOR_ID 0xECC0 + + +/* + * Valid Echo PCI subsystem card IDs + */ +#define DARLA20 0x0010 +#define GINA20 0x0020 +#define LAYLA20 0x0030 +#define DARLA24 0x0040 +#define GINA24 0x0050 +#define LAYLA24 0x0060 +#define MONA 0x0070 +#define MIA 0x0080 +#define INDIGO 0x0090 +#define INDIGO_IO 0x00a0 +#define INDIGO_DJ 0x00b0 +#define DC8 0x00c0 +#define INDIGO_IOX 0x00d0 +#define INDIGO_DJX 0x00e0 +#define ECHO3G 0x0100 + + +/************************************************************************ + + Array sizes and so forth + +***********************************************************************/ + +/* + * Sizes + */ +#define ECHO_MAXAUDIOINPUTS 32 /* Max audio input channels */ +#define ECHO_MAXAUDIOOUTPUTS 32 /* Max audio output channels */ +#define ECHO_MAXAUDIOPIPES 32 /* Max number of input and output + * pipes */ +#define E3G_MAX_OUTPUTS 16 +#define ECHO_MAXMIDIJACKS 1 /* Max MIDI ports */ +#define ECHO_MIDI_QUEUE_SZ 512 /* Max MIDI input queue entries */ +#define ECHO_MTC_QUEUE_SZ 32 /* Max MIDI time code input queue + * entries */ + +/* + * MIDI activity indicator timeout + */ +#define MIDI_ACTIVITY_TIMEOUT_USEC 200000 + + +/**************************************************************************** + + Clocks + +*****************************************************************************/ + +/* + * Clock numbers + */ +#define ECHO_CLOCK_INTERNAL 0 +#define ECHO_CLOCK_WORD 1 +#define ECHO_CLOCK_SUPER 2 +#define ECHO_CLOCK_SPDIF 3 +#define ECHO_CLOCK_ADAT 4 +#define ECHO_CLOCK_ESYNC 5 +#define ECHO_CLOCK_ESYNC96 6 +#define ECHO_CLOCK_MTC 7 +#define ECHO_CLOCK_NUMBER 8 +#define ECHO_CLOCKS 0xffff + +/* + * Clock bit numbers - used to report capabilities and whatever clocks + * are being detected dynamically. + */ +#define ECHO_CLOCK_BIT_INTERNAL (1 << ECHO_CLOCK_INTERNAL) +#define ECHO_CLOCK_BIT_WORD (1 << ECHO_CLOCK_WORD) +#define ECHO_CLOCK_BIT_SUPER (1 << ECHO_CLOCK_SUPER) +#define ECHO_CLOCK_BIT_SPDIF (1 << ECHO_CLOCK_SPDIF) +#define ECHO_CLOCK_BIT_ADAT (1 << ECHO_CLOCK_ADAT) +#define ECHO_CLOCK_BIT_ESYNC (1 << ECHO_CLOCK_ESYNC) +#define ECHO_CLOCK_BIT_ESYNC96 (1 << ECHO_CLOCK_ESYNC96) +#define ECHO_CLOCK_BIT_MTC (1<<ECHO_CLOCK_MTC) + + +/*************************************************************************** + + Digital modes + +****************************************************************************/ + +/* + * Digital modes for Mona, Layla24, and Gina24 + */ +#define DIGITAL_MODE_NONE 0xFF +#define DIGITAL_MODE_SPDIF_RCA 0 +#define DIGITAL_MODE_SPDIF_OPTICAL 1 +#define DIGITAL_MODE_ADAT 2 +#define DIGITAL_MODE_SPDIF_CDROM 3 +#define DIGITAL_MODES 4 + +/* + * Digital mode capability masks + */ +#define ECHOCAPS_HAS_DIGITAL_MODE_SPDIF_RCA (1 << DIGITAL_MODE_SPDIF_RCA) +#define ECHOCAPS_HAS_DIGITAL_MODE_SPDIF_OPTICAL (1 << DIGITAL_MODE_SPDIF_OPTICAL) +#define ECHOCAPS_HAS_DIGITAL_MODE_ADAT (1 << DIGITAL_MODE_ADAT) +#define ECHOCAPS_HAS_DIGITAL_MODE_SPDIF_CDROM (1 << DIGITAL_MODE_SPDIF_CDROM) + + +#define EXT_3GBOX_NC 0x01 /* 3G box not connected */ +#define EXT_3GBOX_NOT_SET 0x02 /* 3G box not detected yet */ + + +#define ECHOGAIN_MUTED (-128) /* Minimum possible gain */ +#define ECHOGAIN_MINOUT (-128) /* Min output gain (dB) */ +#define ECHOGAIN_MAXOUT (6) /* Max output gain (dB) */ +#define ECHOGAIN_MININP (-50) /* Min input gain (0.5 dB) */ +#define ECHOGAIN_MAXINP (50) /* Max input gain (0.5 dB) */ + +#define PIPE_STATE_STOPPED 0 /* Pipe has been reset */ +#define PIPE_STATE_PAUSED 1 /* Pipe has been stopped */ +#define PIPE_STATE_STARTED 2 /* Pipe has been started */ +#define PIPE_STATE_PENDING 3 /* Pipe has pending start */ + + + +struct audiopipe { + volatile __le32 *dma_counter;
