2012-05-14ALSA: firewire-lib: taskletize the snd_pcm_period_elapsed() callClemens Ladisch
The following patch might introduce this call chain: PCM .pointer callback + fw_iso_context_flush_completions + packet callback + snd_pcm_period_elapsed + PCM .pointer callback Recursive calls to the pointer callback are not possible due to the PCM group locking, so avoid this by moving the period notification into a separate tasklet.

Explained by Takashi in <s5hfwbtmz0q.wl%tiwai@suse.de> > The reason is because get_min_max*() isn't called in the place you > created these controls, and get_min_max() would be called only for > integer volumes later even if uninitialized.

2012-05-11ALSA: pcm - Optimize the call of snd_pcm_update_hw_ptr() in read/write loopTakashi Iwai
In the PCM read/write loop, the driver calls snd_pcm_update_hw_ptr() at each time at the beginning of the loop. Russell King reported that this hogs CPU significantly. The current code assumes that the pointer callback is very fast and cheap, also not too much fine grained. It's not true in all cases. When the pointer advances short samples while the read/write copy has been performed, the driver updates the hw_ptr and gets avail > 0 again. Then it tries to read/write these small chunks. This repeats until the avail really gets to zero. For avoiding this situation, a simple workaround is to call snd_pcm_update_hw_ptr() only once at starting the loop, assuming that the read/write copy is performed fast enough. If the available count becomes short, it goes to snd_pcm_wait_avail() anyway, and this processes right.

2012-04-13ALSA: snd-usb: implement new endpoint streaming modelDaniel Mack
This patch adds a new generic streaming logic for audio over USB. It defines a model (snd_usb_endpoint) that handles everything that is related to an USB endpoint and its streaming. There are functions to activate and deactivate an endpoint (which call usb_set_interface()), and to start and stop its URBs. It also has function pointers to be called when data was received or is about to be sent, and pointer to a sync slave (another snd_usb_endpoint) that is informed when data has been received. A snd_usb_endpoint knows about its state and implements a refcounting, so only the first user will actually start the URBs and only the last one to stop it will tear them down again. With this sort of abstraction, the actual streaming is decoupled from the pcm handling, which makes the "implicit feedback" mechanisms easy to implement. In order to split changes properly, this patch only adds the new implementation but leaves the old one around, so the the driver doesn't change its behaviour. The switch to actually use the new code is submitted separately. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2012-04-07ALSA: hda - Remove CD control from model=benq for CX20549Michael Karcher
The ID used for detection of the BenQ R55E actually identifies the Quanta TW3 ODM design, which is also used for the Gigabyte W551 laptop series. Schematics on the internet clearly indicate that the "Port C" (analog input connected to record source #4 and mixer input #4) is unconnected. Playing an audio CD through analog playback (using cdplay from cdtools) produces no sound, even with the mixer input labelled "CD" enabled, and the volume control in the CD drive set to maximum.

2012-04-05ASoC: set idle_bias_off=1 for all platform DAPM contextsStephen Warren
The ASoC core currently defaults to using STANDBY rather than OFF for idle ASoC platform devices, which causes a permanent pm_runtime_get() on them. This keeps the device active unnecessarily. This can be especially problematic when the ASoC platform device and DAI device are the same device. The distinction between OFF and STANDBY is likely not relevant for ASoC platform drivers, since they aren't analog devices. So, solve this issue by hard-coding idle_bias_off = 1 for all ASoC platform devices. If this turns out to be a problem, this value could be sourced from the snd_soc_platform_driver, similarly to soc_probe_codec(). Note: Prior to this change, this caused a large (10) runtime_active count for the Tegra I2S controller even when not in use, and a leak in that value as streams were started and stopped. This change probably hides a bug. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
