I use the following code in my driver to initialize 2 MPU-like ports:
/* Dreamchip MIDI initializer */
static int __devinit snd_dream_midi_init(struct snd_card_dream *dream, struct snd_card_dream_midi *midi, int device, char *name)
{
snd_rawmidi_t *rmidi;
int err;
if ((err = snd_rawmidi_new(dream->card, name, device, 1, 1, &rmidi)) < 0)
return err;
midi->dream = dream;
strcpy(rmidi->name, name);
snd_rawmidi_set_ops(rmidi, SNDRV_RAWMIDI_STREAM_OUTPUT, &snd_dream_midi_output);
snd_rawmidi_set_ops(rmidi, SNDRV_RAWMIDI_STREAM_INPUT, &snd_dream_midi_input);
rmidi->info_flags |= SNDRV_RAWMIDI_INFO_OUTPUT |
SNDRV_RAWMIDI_INFO_INPUT |
SNDRV_RAWMIDI_INFO_DUPLEX;
rmidi->private_data = midi;
midi->rmidi = rmidi;
return 0;
}
/* Dreamchip MIDI constructor */
int __devinit snd_dream_midi(struct snd_card_dream *dream)
{
struct snd_card_dream_midi *midi1 = &dream->midi1;
struct snd_card_dream_midi *midi2 = &dream->midi2;
int err;
if ((err = snd_dream_midi_init(dream, midi1, 0, "Dreamchip MPU interface 1")) < 0)
return err;
midi1->port = MPU1_DATA;
if ((err = snd_dream_midi_init(dream, midi2, 1, "Dreamchip MPU interface 2")) < 0)
return err;
midi2->port = MPU2_DATA;
return 0;
}
But the client names are wrong!
~ # aplaymidi -l
Port Client name Port name
62:0 Midi Through Midi Through Port-0
64:0 Dreamchip MPU interface 1 Dreamchip MPU interface 1
64:32 Dreamchip MPU interface 1 Dreamchip MPU interface 2
88:0 Virtual Raw MIDI 3-0 VirMIDI 3-0
89:0 Virtual Raw MIDI 3-1 VirMIDI 3-1
90:0 Virtual Raw MIDI 3-2 VirMIDI 3-2
91:0 Virtual Raw MIDI 3-3 VirMIDI 3-3
Why do both ports get "Dreamchip MPU interface 1" for the client name?
