Meanwhile bcm2835 driver checks the DRAINING -state and tries to issue some different command. - -This patch straightens things a bit, dropping the incorrect state -checks. The draining behavior would be still not perfect at this -point, but will be improved in a later patch. - -Signed-off-by: Takashi Iwai <tiwai@suse.de> -Tested-by: Stefan Wahren <stefan.wahren@i2se.com> -Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> ---- - .../vc04_services/bcm2835-audio/bcm2835-pcm.c | 18 ++++++------------ - 1 file changed, 6 insertions(+), 12 deletions(-) - ---- a/drivers/staging/vc04_services/bcm2835-audio/bcm2835-pcm.c -+++ b/drivers/staging/vc04_services/bcm2835-audio/bcm2835-pcm.c -@@ -153,7 +153,6 @@ static int snd_bcm2835_playback_open_gen - chip->alsa_stream[idx] = alsa_stream; - - chip->opened |= (1 << idx); -- alsa_stream->draining = 1; - - out: - mutex_unlock(&chip->audio_mutex); -@@ -268,6 +267,7 @@ static int snd_bcm2835_pcm_prepare(struc - alsa_stream->buffer_size = snd_pcm_lib_buffer_bytes(substream); - alsa_stream->period_size = snd_pcm_lib_period_bytes(substream); - alsa_stream->pos = 0; -+ alsa_stream->draining = false; - - audio_debug("buffer_size=%d, period_size=%d pos=%d frame_bits=%d\n", - alsa_stream->buffer_size, alsa_stream->period_size, -@@ -312,21 +312,15 @@ static int snd_bcm2835_pcm_trigger(struc - switch (cmd) { - case SNDRV_PCM_TRIGGER_START: - err = bcm2835_audio_start(alsa_stream); -- if (!err) -- alsa_stream->draining = 1; -- else -+ if (err) - audio_error(" Failed to START alsa device (%d)\n", err); - break; -+ case SNDRV_PCM_TRIGGER_DRAIN: -+ alsa_stream->draining = true; -+ break; - case SNDRV_PCM_TRIGGER_STOP: -- if (runtime->status->state == SNDRV_PCM_STATE_DRAINING) { -- audio_info("DRAINING\n"); -- alsa_stream->draining = 1; -- } else { -- audio_info("DROPPING\n"); -- alsa_stream->draining = 0; -- } - err = bcm2835_audio_stop(alsa_stream); -- if (err != 0) -+ if (err) - audio_error(" Failed to STOP alsa device (%d)\n", err); - break; - default: |
