All core components in ALSA already provide adequate locking in their open()-functions and do not require the big kernel lock, so there is no need to add the BKL there.

However, there are special situations where one wants to reduce the overall volume in the digital domain, i.e., before the AC'97 codec's PCM volume control. To allow this, add a module parameter that sets the initial DXS volume. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Tested-by: Soeren D.

To avoid this situation, the virtual period clocking was changed to shorten the next timing period when our timing voice falls too far behind the capture voice. In addition, the first virtual period for the timing voice was slightly too short, causing the timing voice to initially be ahead of the capture voice. While tracking down this problem, I noticed that the expected sample offset was being incorrectly initialized, causing an overrun to be incorrectly reported when the timing voice happened to be perfectly synchronized.

| | | * | | ALSA: pcm_lib: avoid timing jitter in snd_pcm_read/write()David Dillow2010-06-281-8/+15

However, When using snd_pcm_read/write(), one gets a jittery delay that alternates between less than a millisecond and approximately two period times. This is caused by snd_pcm_lib_{read,write}1() transferring any available samples to the user's buffer and adjusting the application pointer prior to sleeping to the end of the current period. When the next period interrupt occurs, there is then less than avail_min samples remaining to be transferred in the period, so we end up sleeping until a second period occurs. This is solved by using runtime->twake as the number of samples needed for a wakeup in addition to selecting the proper wait queue to wake in snd_pcm_update_state(). This requires twake to be non-zero when used by snd_pcm_lib_{read,write}1() even if avail_min is zero. Signed-off-by: Dave Dillow <dave@thedillows.org> Signed-off-by: Jaroslav Kysela <perex@perex.cz>

Before this patch, when the user changed from analog source to digital there were a short time, when the codec enabled analog mic bias (2.2 volts) instead of the correct digital mic bias (1.8 volts) to the digital microphones. This behaviour caused by the former implementation of selecting the correct type of bias. This was done at the POST_REG event of the DAPM_MUX_E("TXx Capture Route") widget. By moving the bias type selection as DAPM_SUPPLY and connecting it to the corresponding digimic widget the problematic situation can be avoided.

The device supports PCM data input word lengths from 16 to 32-bits and sampling rates up to 192kHz. The WM8741 also supports DSD bit-stream data format, in both direct DSD and PCM-converted DSD modes. TODO: Expand wm8741_set_dai_sysclk and rate_constraint members to allow for all supported sample rate / Master Clock frequency combinations. Fully enable control of supplies.

With the extended THRESHOLD mode user space can ask for any period size it wishes, and the driver will configure the sDMA and McBSP FIFO accordingly. Replace the hw_rule for the period size with static constraint, which will make sure that the period size will be always even (to avoid prime period size, which could be possible in mono stream) Signed-off-by: Peter Ujfalusi <peter.ujfalusi@nokia.com> Acked-by: Jarkko Nikula <jhnikula@gmail.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>

When the sDMA is configured for packet mode, the sDMA frame size does not need to match with the McBSP threshold configuration. Uppon DMA request the sDMA will transfer packet size number of words, and still trigger interrupt on frame boundary. The patch extends the original THRESHOLD mode by doing the following: if (period_words <= max_threshold) Current THRESHOLD mode configuration Otherwise (period_words > max_threshold) McBSP threshold = sDMA packet size sDMA frame size = period size With the extended THRESHOLD mode we can remove the constraint for the maximum period size, since if the period size is bigger than the maximum allowed threshold, than the driver will switch to packet mode, and picks the best (biggest) threshold value, which can divide evenly the period size.
