Why do Rule 9 [e1cfeea0]: PERIODS = [6 22] -> empty ?
----------------------------------------------------------------------
Raymond - 01-31-06 09:48
----------------------------------------------------------------------
It seem that au88x0 is the only driver which use
snd_pcm_hw_constraint_pow2()
/* Force equal size periods */
if ((err =
snd_pcm_hw_constraint_integer(runtime,
SNDRV_PCM_HW_PARAM_PERIODS)) < 0)
return err;
/* Avoid PAGE_SIZE boundary to fall inside of a period. */
if ((err =
snd_pcm_hw_constraint_pow2(runtime, 0,
SNDRV_PCM_HW_PARAM_PERIOD_BYTES)) < 0)
return err;
----------------------------------------------------------------------
perex - 01-31-06 10:19
----------------------------------------------------------------------
Yes and no. It's combination pow2 and periods == integer issue. If the
buffer size is 24000 and period size is 2048, then 24000 / 2048 = 11.7188
which is not integer value and then configuration fails.
In this case depends on the parameter order. Or a better fix maybe to
describe that buffer_size must be N * period_size with pow2 restriction
(create a list with all combinations).
I've tried to add a workaround to snd_pcm_set_params() to CVS, but it does
not prevent other apps using the hw_params ALSA API directly to fail.
----------------------------------------------------------------------
perex - 01-31-06 10:26
----------------------------------------------------------------------
To be sure: I'm talking about SNDRV_PCM_HW_PARAM_BUFFER_BYTES restriction.
See pci/emu10k1/emupcm.c code how you can use the
snd_pcm_hw_constraint_list() for this parameter.

There are a number of bugs in snd_vortex_playback_hw_adb
1) capture channels is 2

2) Turtle Beach Montego II (au8830) has stereo codec STAC9721, rear
channels seem to use I2S on the daugther card, other au8830 have quad
codec.
3) SQ1500 (au8810) SuperQuad , other au8810 have stereo codec

Why do Rule 9 [e1cfeea0]: PERIODS = [6 22] -> empty ?
----------------------------------------------------------------------
Raymond - 01-31-06 09:48
----------------------------------------------------------------------
It seem that au88x0 is the only driver which use
snd_pcm_hw_constraint_pow2()
/* Force equal size periods */
if ((err =
snd_pcm_hw_constraint_integer(runtime,
SNDRV_PCM_HW_PARAM_PERIODS)) < 0)
return err;
/* Avoid PAGE_SIZE boundary to fall inside of a period. */
if ((err =
snd_pcm_hw_constraint_pow2(runtime, 0,
SNDRV_PCM_HW_PARAM_PERIOD_BYTES)) < 0)
return err;
----------------------------------------------------------------------
perex - 01-31-06 10:19
----------------------------------------------------------------------
Yes and no. It's combination pow2 and periods == integer issue. If the
buffer size is 24000 and period size is 2048, then 24000 / 2048 = 11.7188
which is not integer value and then configuration fails.
In this case depends on the parameter order. Or a better fix maybe to
describe that buffer_size must be N * period_size with pow2 restriction
(create a list with all combinations).
I've tried to add a workaround to snd_pcm_set_params() to CVS, but it does
not prevent other apps using the hw_params ALSA API directly to fail.
----------------------------------------------------------------------
perex - 01-31-06 10:26
----------------------------------------------------------------------
To be sure: I'm talking about SNDRV_PCM_HW_PARAM_BUFFER_BYTES restriction.
See pci/emu10k1/emupcm.c code how you can use the
snd_pcm_hw_constraint_list() for this parameter.

There are a number of bugs in snd_vortex_playback_hw_adb
1) capture channels is 2
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1766
2) Turtle Beach Montego II (au8830) has stereo codec STAC9721, rear
channels seem to use I2S on the daugther card, other au8830 have quad
codec.
3) SQ1500 (au8810) SuperQuad , other au8810 have stereo codec

Why do Rule 9 [e1cfeea0]: PERIODS = [6 22] -> empty ?
----------------------------------------------------------------------
Raymond - 01-31-06 09:48
----------------------------------------------------------------------
It seem that au88x0 is the only driver which use
snd_pcm_hw_constraint_pow2()
/* Force equal size periods */
if ((err =
snd_pcm_hw_constraint_integer(runtime,
SNDRV_PCM_HW_PARAM_PERIODS)) < 0)
return err;
/* Avoid PAGE_SIZE boundary to fall inside of a period. */
if ((err =
snd_pcm_hw_constraint_pow2(runtime, 0,
SNDRV_PCM_HW_PARAM_PERIOD_BYTES)) < 0)
return err;
----------------------------------------------------------------------
perex - 01-31-06 10:19
----------------------------------------------------------------------
Yes and no. It's combination pow2 and periods == integer issue. If the
buffer size is 24000 and period size is 2048, then 24000 / 2048 = 11.7188
which is not integer value and then configuration fails.
In this case depends on the parameter order. Or a better fix maybe to
describe that buffer_size must be N * period_size with pow2 restriction
(create a list with all combinations).
I've tried to add a workaround to snd_pcm_set_params() to CVS, but it does
not prevent other apps using the hw_params ALSA API directly to fail.
----------------------------------------------------------------------
perex - 01-31-06 10:26
----------------------------------------------------------------------
To be sure: I'm talking about SNDRV_PCM_HW_PARAM_BUFFER_BYTES restriction.
See pci/emu10k1/emupcm.c code how you can use the
snd_pcm_hw_constraint_list() for this parameter.

Do we need to define fifo_size in snd_pcm_hardware ?
.fifo_size = FIFO_SIZE
----------------------------------------------------------------------
Raymond - 02-02-06 10:23
----------------------------------------------------------------------
latency required overall latency in us (0 = optimum latency for players)
Do the latency time a multiple of the time to play one sample (i.e. depend
on the sample rate ) ?

latency required overall latency in us (0 = optimum latency for players)
Do the latency time need to be a multiple of the time to play one sample
(i.e. depend on the sample rate ) ?
1 sample of 48000Hz is 20833.33333us.

Is the pcm_min.c used to demonstrate snd_pcm_recover() the underrun
condition ?
unsigned char buffer[16*1024]; /* some random data */
frames = snd_pcm_writei(handle, buffer, sizeof(buffer));
It do not call snd_pcm_get_params() to obtain period_size and buffer_size
?

Raymond - 02-06-06 06:15
----------------------------------------------------------------------
Would anyone explain why
period_time = latency / 4;
in snd_pcm_set_params()
Do the driver look for maximum buffer size ?
buffer_size * rate <= latency
----------------------------------------------------------------------
Raymond - 02-07-06 07:35
----------------------------------------------------------------------
It is not pratical to describe that buffer_size must be N * period_size
with pow2 restriction.

aplay -D hw:0,0 can find a safe value of period_size for all .wav files in
the vortex driver CD without underrun. The period_size varies between
different rate and format
However if I specified aplay to use any period-size less than 32, the
message will appear in the system log

Hi,
The messages of the kind:
vortex: 0 virt=2, real=2, delta=2
vortex: 0 virt=11, real=3, delta=2
appear when your system is lossing interrupts because of overload. You are
asking your computer to do something it is not capable of. Thats it.
period size is measured in frames and period_bytes in bytes. AFAIK any
size is meant to be in frames.
Best Regards
Manuel Jander

Hi,
The messages of the kind:
vortex: 0 virt=2, real=2, delta=2
vortex: 0 virt=11, real=3, delta=2
appear when your system is lossing interrupts because of overload. You are
asking your computer to do something it is not capable of. Thats it.
period size is measured in frames and period_bytes in bytes. AFAIK any
size is meant to be in frames.
Best Regards
Manuel Jander

Is it possible for au8830 to support surround51 by panning the center to
front speakers and bass to 4 speakers ?

Can those parameters runtime->rate, runtime->format, runtime->channels
pass to prepare callback different from those accepted by hw_params
callback ?
As mixer, src are dynamically allocated, the current au88x0 driver do not
support any change in runtime->channels after hw_params callback.
snd_pcm_recover() will call snd_pcm_prepare() when underrun occur.
Which runtime parameters will be changed when underrun occur ?

What is the difference between "default" and "hw:0" pcm of au88x0 in
alsa-1.0.11rc3 ?
1) Do "default" pcm support more format than "hw:0" ?
(e.g. SNDRV_PCM_FMTBIT_S16_BE, SNDRV_PCM_FMTBIT_S8, 24 bits format)
2) Do "default" pcm allow resample ? (e.g. 96000Hz )
3) Is the usage of snd_pcm_set_params() limited to "default" ?
4) What is the effect of set soft_resample = 1 in snd_pcm_set_params() for
SND_PCM_TYPE_HW pcm ?

Hi,
The messages of the kind:
vortex: 0 virt=2, real=2, delta=2
vortex: 0 virt=11, real=3, delta=2
appear when your system is lossing interrupts because of overload. You are
asking your computer to do something it is not capable of. Thats it.
period size is measured in frames and period_bytes in bytes. AFAIK any
size is meant to be in frames.
Best Regards
Manuel Jander

Whenever snd_pcm_hw_params_set_buffer_time_near() or
snd_pcm_hw_params_set_period_time_near() fail, the error is irrecoverable
However this behaviour seem undocumented in alsa-lib
snd_pcm_hw_params_test_buffer_time() should be used instead of
snd_pcm_hw_params_set_buffer_time_near()

Whenever snd_pcm_hw_params_set_buffer_time_near() or
snd_pcm_hw_params_set_period_time_near() fail, the error is irrecoverable
However this behaviour seem undocumented in alsa-lib
snd_pcm_hw_params_test_buffer_time() should be used instead of
snd_pcm_hw_params_set_buffer_time_near()

The original subject of the bug report is "simple PCM helper function".
a bug report about snd_pcm_set_params() and snd_pcm_get_params()
I just want to report some alsa driver (e.g. au88x0) has problem in using
the new alsa-lib functions
I don't know why perex change the subject to "au88x0 PCM configuration
problem - buffer_size constraint"
The DMA of au88x0 seem to have different mode, the au88x0 driver currently
seem to use IRQ_PCMOUT 0x0020 /* PCM OUT page crossing */ , this can be
verified by adding printk statement in vortex_interrupt() using 12.288Mhz
clock tick (VORTEX_SMP_TIME) to calculate the time interval between
snd_pcm_period_elapsed()
It seem that the au88x0 cannot use a very small buffer size (e.g. 2) when
using IRQ_PCMOUT
Does it mean that we need to change some constraints in
snd_vortex_pcm_open() ?

I just want to report some alsa driver (e.g. au88x0) has problem in using

I don't know why perex change the subject to "au88x0 PCM configuration

https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1766 - which is caused by
incorrect capture channels 4
The DMA of au88x0 seem to have different mode, the au88x0 driver currently
seem to use IRQ_PCMOUT 0x0020 /* PCM OUT page crossing */ , this can be
verified by adding printk statement in vortex_interrupt() using 12.288Mhz

----------------------------------------------------------------------
Raymond - 07-02-06 09:24
----------------------------------------------------------------------
Refer to alsa-lib-1.0.12rc1/test/pcm_min.c
Is the parameter "latency" used to refine the two constraints (period_size
and buffer_size) to an unique value ?
As pcm_min.c use "default" in snd_pcm_set_params(), and "default" of
intel8x0 use dmix.
Do dmix introduce any latency when mixing several PCM playback streams ?
Do snd_pcm_set_params() return error if the specified latency is less than
the latency of dmix ?

Refer to alsa-lib-1.0.12rc1/test/pcm_min.c
Is the parameter "latency" used to refine the two constraints (period_size
and buffer_size) to an unique value ?
As pcm_min.c use "default" in snd_pcm_set_params(), and "default" of
intel8x0 use dmix.
Do dmix introduce any latency when mixing several PCM playback streams ?
Do snd_pcm_set_params() return error if the specified latency is less than
the latency of dmix ?

Since most common rates (22050, 44100, 48000, ...) are mulitple of 3, there
is some accuracy loss due to rounding as
period time = period bytes / rate
buffer time = buffer bytes / rate

alsa-lib example (i.e. pcm.c and pcm_min.c in alsa-lib-1.0.12rc1/test) can
be run after comment out the power 2 constraints and set period_bytes_min
to 4096 (i.e. period bytes = 4K page and the constraint period bytes is
unique.)
It is strange that snd_pcm_set_params() does not return error when the
parameter latency is set to any value less than the time to play a sample.
/*
if ((err =
snd_pcm_hw_constraint_pow2(runtime, 0,
SNDRV_PCM_HW_PARAM_PERIOD_BYTES)) < 0)
return err;
*/
...
if (VORTEX_PCM_TYPE(substream->pcm) == VORTEX_PCM_ADB) {
runtime->hw = snd_vortex_playback_hw_adb;
if (substream->stream ==
SNDRV_PCM_STREAM_PLAYBACK) {
if (VORTEX_IS_QUAD(vortex)) {
runtime->hw.channels_max = 4;
snd_pcm_hw_constraint_list(runtime, 0,
SNDRV_PCM_HW_PARAM_CHANNELS,
&hw_constraints_channels4);
}
else
runtime->hw.channels_max = 2;
}
else
runtime->hw.channels_max = 2;
runtime->hw.period_bytes_min = 4096;
};
However running another example (latency) freeze the computer immediately
without display any message.
Apply alsa-timer-irqsave.patch in
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=952 , running latency
display the
parameter but still freeze the computer immediately
alsa-timer-irqsave.patch only change the spin_lock and spin_unlock at the
beginning and the end of snd_timer_tasklet()
How about the spin_lock() and spin_unlock() inside the while loop in
snd_timer_tasklet() ?

alsa-lib example (i.e. pcm.c and pcm_min.c in alsa-lib-1.0.12rc1/test) can
be run after comment out the power 2 constraints and set period_bytes_min
to 4096 (i.e. period bytes = 4K page and the constraint period bytes is
unique.)
It is strange that snd_pcm_set_params() does not return error when the
parameter latency is set to any value less than the time to play a sample.
/*
if ((err =
snd_pcm_hw_constraint_pow2(runtime, 0,
SNDRV_PCM_HW_PARAM_PERIOD_BYTES)) < 0)
return err;
*/
...
if (VORTEX_PCM_TYPE(substream->pcm) == VORTEX_PCM_ADB) {
runtime->hw = snd_vortex_playback_hw_adb;
if (substream->stream ==
SNDRV_PCM_STREAM_PLAYBACK) {
if (VORTEX_IS_QUAD(vortex)) {
runtime->hw.channels_max = 4;
snd_pcm_hw_constraint_list(runtime, 0,
SNDRV_PCM_HW_PARAM_CHANNELS,
&hw_constraints_channels4);
}
else
runtime->hw.channels_max = 2;
}
else
runtime->hw.channels_max = 2;
runtime->hw.period_bytes_min = 4096;
};
Are there any requirement of period_bytes to run another example latency.c
?
However running another example (latency) freeze the computer immediately
without display any message.
Apply alsa-timer-irqsave.patch in
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=952 , running latency
display the
parameter but still freeze the computer immediately
alsa-timer-irqsave.patch only change the spin_lock and spin_unlock at the
beginning and the end of snd_timer_tasklet()
How about the spin_lock() and spin_unlock() inside the while loop in
snd_timer_tasklet() ?

This means the alsa-lib example codec (alsa-lib/test/pcm.c) should also
check
check whether the buffer_time or period_time after calling
snd_pcm_hw_params_set_buffer_time_near() or
snd_pcm_hw_params_set_period_time_near() to determine the actual
buffer_time or period_time.

This means the alsa-lib example code (pcm.c and pcm_min.c) should also
need to check buffer_time or period_time after calling
snd_pcm_hw_params_set_buffer_time_near() or
snd_pcm_hw_params_set_period_time_near() to determine the actual
buffer_time or period_time.

The following also work, however it seem that the 64K SG buffer is just
enough for 16 streams (4K buffer each)
static unsigned int adb_buffer_sizes[16] = {
4096, 4096*2, 4096*3, 4096*4,
4096*5, 4096*6, 4096*7, 4096*8,
4096*9, 4096*10,4096*11,4096*12,
4096*13,4096*14,4096*15,4096*16,
};
snd_pcm_hw_constraint_list(runtime, 0, SNDRV_PCM_HW_PARAM_BUFFER_BYTES,
&hw_constraints_adb_buffer_sizes);

This means the alsa-lib example code (pcm.c and pcm_min.c) should also
need to check buffer_time or period_time after calling
snd_pcm_hw_params_set_buffer_time_near() or
snd_pcm_hw_params_set_period_time_near() to determine the actual
buffer_time or period_time.
----------------------------------------------------------------------
Raymond - 07-13-06 04:27
----------------------------------------------------------------------
If the driver has one and only one period bytes,
snd_pcm_hw_params_set_buffer_time_near() or
snd_pcm_hw_params_set_period_time_near() will not fail.
It seem that the parameter latency in snd_pcm_set_params() is quite
misleading.
