The SGI Visual Workstations (models 320 and 540) are based around
|
||||
the Cobalt, Lithium, and Arsenic ASICs. The Cobalt ASIC is the
|
||||
main system ASIC which interfaces the 1-4 IA32 cpus, the memory
|
||||
system, and the I/O system in the Lithium ASIC. The Cobalt ASIC
|
||||
also contains the 3D gfx rendering engine which renders to main
|
||||
system memory -- part of which is used as the frame buffer which
|
||||
is DMA'ed to a video connector using the Arsenic ASIC. A PIIX4
|
||||
chip and NS87307 are used to provide legacy device support (IDE,
|
||||
serial, floppy, and parallel).
|
||||
|
||||
The Visual Workstation chipset largely conforms to the PC architecture
|
||||
with some notable exceptions such as interrupt handling.

vwsnd - Sound driver for the Silicon Graphics 320 and 540 Visual
|
||||
Workstations' onboard audio.
|
||||
|
||||
Copyright 1999 Silicon Graphics, Inc. All rights reserved.
|
||||
|
||||
|
||||
At the time of this writing, March 1999, there are two models of
|
||||
Visual Workstation, the 320 and the 540. This document only describes
|
||||
those models. Future Visual Workstation models may have different
|
||||
sound capabilities, and this driver will probably not work on those
|
||||
boxes.
|
||||
|
||||
The Visual Workstation has an Analog Devices AD1843 "SoundComm" audio
|
||||
codec chip. The AD1843 is accessed through the Cobalt I/O ASIC, also
|
||||
known as Lithium. This driver programs both chips.
|
||||
|
||||
==============================================================================
|
||||
QUICK CONFIGURATION
|
||||
|
||||
# insmod soundcore
|
||||
# insmod vwsnd
|
||||
|
||||
==============================================================================
|
||||
I/O CONNECTIONS
|
||||
|
||||
On the Visual Workstation, only three of the AD1843 inputs are hooked
|
||||
up. The analog line in jacks are connected to the AD1843's AUX1
|
||||
input. The CD audio lines are connected to the AD1843's AUX2 input.
|
||||
The microphone jack is connected to the AD1843's MIC input. The mic
|
||||
jack is mono, but the signal is delivered to both the left and right
|
||||
MIC inputs. You can record in stereo from the mic input, but you will
|
||||
get the same signal on both channels (within the limits of A/D
|
||||
accuracy). Full scale on the Line input is +/- 2.0 V. Full scale on
|
||||
the MIC input is 20 dB less, or +/- 0.2 V.
|
||||
|
||||
The AD1843's LOUT1 outputs are connected to the Line Out jacks. The
|
||||
AD1843's HPOUT outputs are connected to the speaker/headphone jack.
|
||||
LOUT2 is not connected. Line out's maximum level is +/- 2.0 V peak to
|
||||
peak. The speaker/headphone out's maximum is +/- 4.0 V peak to peak.
|
||||
|
||||
The AD1843's PCM input channel and one of its output channels (DAC1)
|
||||
are connected to Lithium. The other output channel (DAC2) is not
|
||||
connected.
|
||||
|
||||
==============================================================================
|
||||
CAPABILITIES
|
||||
|
||||
The AD1843 has PCM input and output (Pulse Code Modulation, also known
|
||||
as wavetable). PCM input and output can be mono or stereo in any of
|
||||
four formats. The formats are 16 bit signed and 8 bit unsigned,
|
||||
u-Law, and A-Law format. Any sample rate from 4 KHz to 49 KHz is
|
||||
available, in 1 Hz increments.
|
||||
|
||||
The AD1843 includes an analog mixer that can mix all three input
|
||||
signals (line, mic and CD) into the analog outputs. The mixer has a
|
||||
separate gain control and mute switch for each input.
|
||||
|
||||
There are two outputs, line out and speaker/headphone out. They
|
||||
always produce the same signal, and the speaker always has 3 dB more
|
||||
gain than the line out. The speaker/headphone output can be muted,
|
||||
but this driver does not export that function.
|
||||
|
||||
The hardware can sync audio to the video clock, but this driver does
|
||||
not have a way to specify syncing to video.
|
||||
|
||||
==============================================================================
|
||||
PROGRAMMING
|
||||
|
||||
This section explains the API supported by the driver. Also see the
|
||||
Open Sound Programming Guide at http://www.opensound.com/pguide/ .
|
||||
This section assumes familiarity with that document.
|
||||
|
||||
The driver has two interfaces, an I/O interface and a mixer interface.
|
||||
There is no MIDI or sequencer capability.
|
||||
|
||||
==============================================================================
|
||||
PROGRAMMING PCM I/O
|
||||
|
||||
The I/O interface is usually accessed as /dev/audio or /dev/dsp.
|
||||
Using the standard Open Sound System (OSS) ioctl calls, the sample
|
||||
rate, number of channels, and sample format may be set within the
|
||||
limitations described above. The driver supports triggering. It also
|
||||
supports getting the input and output pointers with one-sample
|
||||
accuracy.
|
||||
|
||||
The SNDCTL_DSP_GETCAP ioctl returns these capabilities.
|
||||
|
||||
DSP_CAP_DUPLEX - driver supports full duplex.
|
||||
|
||||
DSP_CAP_TRIGGER - driver supports triggering.
|
||||
|
||||
DSP_CAP_REALTIME - values returned by SNDCTL_DSP_GETIPTR
|
||||
and SNDCTL_DSP_GETOPTR are accurate to a few samples.
|
||||
|
||||
Memory mapping (mmap) is not implemented.
|
||||
|
||||
The driver permits subdivided fragment sizes from 64 to 4096 bytes.
|
||||
The number of fragments can be anything from 3 fragments to however
|
||||
many fragments fit into 124 kilobytes. It is up to the user to
|
||||
determine how few/small fragments can be used without introducing
|
||||
glitches with a given workload. Linux is not realtime, so we can't
|
||||
promise anything. (sigh...)
|
||||
|
||||
When this driver is switched into or out of mu-Law or A-Law mode on
|
||||
output, it may produce an audible click. This is unavoidable. To
|
||||
prevent clicking, use signed 16-bit mode instead, and convert from
|
||||
mu-Law or A-Law format in software.
|
||||
|
||||
==============================================================================
|
||||
PROGRAMMING THE MIXER INTERFACE
|
||||
|
||||
The mixer interface is usually accessed as /dev/mixer. It is accessed
|
||||
through ioctls. The mixer allows the application to control gain or
|
||||
mute several audio signal paths, and also allows selection of the
|
||||
recording source.
|
||||
|
||||
Each of the constants described here can be read using the
|
||||
MIXER_READ(SOUND_MIXER_xxx) ioctl. Those that are not read-only can
|
||||
also be written using the MIXER_WRITE(SOUND_MIXER_xxx) ioctl. In most
|
||||
cases, <sys/soundcard.h> defines constants SOUND_MIXER_READ_xxx and
|
||||
SOUND_MIXER_WRITE_xxx which work just as well.
|
||||
|
||||
SOUND_MIXER_CAPS Read-only
|
||||
|
||||
This is a mask of optional driver capabilities that are implemented.
|
||||
This driver's only capability is SOUND_CAP_EXCL_INPUT, which means
|
||||
that only one recording source can be active at a time.
|
||||
|
||||
SOUND_MIXER_DEVMASK Read-only
|
||||
|
||||
This is a mask of the sound channels. This driver's channels are PCM,
|
||||
LINE, MIC, CD, and RECLEV.
|
||||
|
||||
SOUND_MIXER_STEREODEVS Read-only
|
||||
|
||||
This is a mask of which sound channels are capable of stereo. All
|
||||
channels are capable of stereo. (But see caveat on MIC input in I/O
|
||||
CONNECTIONS section above).
|
||||
|
||||
SOUND_MIXER_OUTMASK Read-only
|
||||
|
||||
This is a mask of channels that route inputs through to outputs.
|
||||
Those are LINE, MIC, and CD.
|
||||
|
||||
SOUND_MIXER_RECMASK Read-only
|
||||
|
||||
This is a mask of channels that can be recording sources. Those are
|
||||
PCM, LINE, MIC, CD.
|
||||
|
||||
SOUND_MIXER_PCM Default: 0x5757 (0 dB)
|
||||
|
||||
This is the gain control for PCM output. The left and right channel
|
||||
gain are controlled independently. This gain control has 64 levels,
|
||||
which range from -82.5 dB to +12.0 dB in 1.5 dB steps. Those 64
|
||||
levels are mapped onto 100 levels at the ioctl, see below.
|
||||
|
||||
SOUND_MIXER_LINE Default: 0x4a4a (0 dB)
|
||||
|
||||
This is the gain control for mixing the Line In source into the
|
||||
outputs. The left and right channel gain are controlled
|
||||
independently. This gain control has 32 levels, which range from
|
||||
-34.5 dB to +12.0 dB in 1.5 dB steps. Those 32 levels are mapped onto
|
||||
100 levels at the ioctl, see below.
|
||||
|
||||
SOUND_MIXER_MIC Default: 0x4a4a (0 dB)
|
||||
|
||||
This is the gain control for mixing the MIC source into the outputs.
|
||||
The left and right channel gain are controlled independently. This
|
||||
gain control has 32 levels, which range from -34.5 dB to +12.0 dB in
|
||||
1.5 dB steps. Those 32 levels are mapped onto 100 levels at the
|
||||
ioctl, see below.
|
||||
|
||||
SOUND_MIXER_CD Default: 0x4a4a (0 dB)
|
||||
|
||||
This is the gain control for mixing the CD audio source into the
|
||||
outputs. The left and right channel gain are controlled
|
||||
independently. This gain control has 32 levels, which range from
|
||||
-34.5 dB to +12.0 dB in 1.5 dB steps. Those 32 levels are mapped onto
|
||||
100 levels at the ioctl, see below.
|
||||
|
||||
SOUND_MIXER_RECLEV Default: 0 (0 dB)
|
||||
|
||||
This is the gain control for PCM input (RECording LEVel). The left
|
||||
and right channel gain are controlled independently. This gain
|
||||
control has 16 levels, which range from 0 dB to +22.5 dB in 1.5 dB
|
||||
steps. Those 16 levels are mapped onto 100 levels at the ioctl, see
|
||||
below.
|
||||
|
||||
SOUND_MIXER_RECSRC Default: SOUND_MASK_LINE
|
||||
|
||||
This is a mask of currently selected PCM input sources (RECording
|
||||
SouRCes). Because the AD1843 can only have a single recording source
|
||||
at a time, only one bit at a time can be set in this mask. The
|
||||
allowable values are SOUND_MASK_PCM, SOUND_MASK_LINE, SOUND_MASK_MIC,
|
||||
or SOUND_MASK_CD. Selecting SOUND_MASK_PCM sets up internal
|
||||
resampling which is useful for loopback testing and for hardware
|
||||
sample rate conversion. But software sample rate conversion is
|
||||
probably faster, so I don't know how useful that is.
|
||||
|
||||
SOUND_MIXER_OUTSRC DEFAULT: SOUND_MASK_LINE|SOUND_MASK_MIC|SOUND_MASK_CD
|
||||
|
||||
This is a mask of sources that are currently passed through to the
|
||||
outputs. Those sources whose bits are not set are muted.
|
||||
|
||||
==============================================================================
|
||||
GAIN CONTROL
|
||||
|
||||
There are five gain controls listed above. Each has 16, 32, or 64
|
||||
steps. Each control has 1.5 dB of gain per step. Each control is
|
||||
stereo.
|
||||
|
||||
The OSS defines the argument to a channel gain ioctl as having two
|
||||
components, left and right, each of which ranges from 0 to 100. The
|
||||
two components are packed into the same word, with the left side gain
|
||||
in the least significant byte, and the right side gain in the second
|
||||
least significant byte. In C, we would say this.
|
||||
|
||||
#include <assert.h>
|
||||
|
||||
...
|
||||
|
||||
assert(leftgain >= 0 && leftgain <= 100);
|
||||
assert(rightgain >= 0 && rightgain <= 100);
|
||||
arg = leftgain | rightgain << 8;
|
||||
|
||||
So each OSS gain control has 101 steps. But the hardware has 16, 32,
|
||||
or 64 steps. The hardware steps are spread across the 101 OSS steps
|
||||
nearly evenly. The conversion formulas are like this, given N equals
|
||||
16, 32, or 64.
|
||||
|
||||
int round = N/2 - 1;
|
||||
OSS_gain_steps = (hw_gain_steps * 100 + round) / (N - 1);
|
||||
hw_gain_steps = (OSS_gain_steps * (N - 1) + round) / 100;
|
||||
|
||||
Here is a snippet of C code that will return the left and right gain
|
||||
of any channel in dB. Pass it one of the predefined gain_desc_t
|
||||
structures to access any of the five channels' gains.
|
||||
|
||||
typedef struct gain_desc {
|
||||
float min_gain;
|
||||
float gain_step;
|
||||
int nbits;
|
||||
int chan;
|
||||
} gain_desc_t;
|
||||
|
||||
const gain_desc_t gain_pcm = { -82.5, 1.5, 6, SOUND_MIXER_PCM };
|
||||
const gain_desc_t gain_line = { -34.5, 1.5, 5, SOUND_MIXER_LINE };
|
||||
const gain_desc_t gain_mic = { -34.5, 1.5, 5, SOUND_MIXER_MIC };
|
||||
const gain_desc_t gain_cd = { -34.5, 1.5, 5, SOUND_MIXER_CD };
|
||||
const gain_desc_t gain_reclev = { 0.0, 1.5, 4, SOUND_MIXER_RECLEV };
|
||||
|
||||
int get_gain_dB(int fd, const gain_desc_t *gp,
|
||||
float *left, float *right)
|
||||
{
|
||||
int word;
|
||||
int lg, rg;
|
||||
int mask = (1 << gp->nbits) - 1;
|
||||
|
||||
if (ioctl(fd, MIXER_READ(gp->chan), &word) != 0)
|
||||
return -1; /* fail */
|
||||
lg = word & 0xFF;
|
||||
rg = word >> 8 & 0xFF;
|
||||
lg = (lg * mask + mask / 2) / 100;
|
||||
rg = (rg * mask + mask / 2) / 100;
|
||||
*left = gp->min_gain + gp->gain_step * lg;
|
||||
*right = gp->min_gain + gp->gain_step * rg;
|
||||
return 0;
|
||||
}
|
||||
|
||||
And here is the corresponding routine to set a channel's gain in dB.
|
||||
|
||||
int set_gain_dB(int fd, const gain_desc_t *gp, float left, float right)
|
||||
{
|
||||
float max_gain =
|
||||
gp->min_gain + (1 << gp->nbits) * gp->gain_step;
|
||||
float round = gp->gain_step / 2;
|
||||
int mask = (1 << gp->nbits) - 1;
|
||||
int word;
|
||||
int lg, rg;
|
||||
|
||||
if (left < gp->min_gain || right < gp->min_gain)
|
||||
return EINVAL;
|
||||
lg = (left - gp->min_gain + round) / gp->gain_step;
|
||||
rg = (right - gp->min_gain + round) / gp->gain_step;
|
||||
if (lg >= (1 << gp->nbits) || rg >= (1 << gp->nbits))
|
||||
return EINVAL;
|
||||
lg = (100 * lg + mask / 2) / mask;
|
||||
rg = (100 * rg + mask / 2) / mask;
|
||||
word = lg | rg << 8;
|
