* ASoC: Fix possible codec_dai->ops NULL pointer problemsBarry Song2009-10-19
| | | | | | | | | | Some codec DAIs like stac9766, wm9712, wm9713, ad1980 don't register themselves then it loses to the chance to be given a null_dai_ops in snd_soc_register_dai if they have no ops. When functions like soc_pcm_open, soc_pcm_hw_params etc. access the ops field in these DAIs, panic will happen.

* ASoC: Serialize access to dapm_power_widgets()Eero Nurkkala2009-10-13
| | | | | | | | | | | | | | | | | | | | Access to damp_power_widgets() is assumed to be single-threaded. Concurrent accesses to dapm_power_widgets() may result in unpredictable behavior. Calls from: close_delayed_work() soc_codec_close() soc_pcm_prepare() soc_suspend() soc_resume_deferred() to snd_soc_dapm_stream_event() do not have the codec->mutex taken to cover the call to dapm_power_widgets(). Thus, take the mutex in these paths also to assure single-threaded use of dapm_power_widgets().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the SND_SOC_DAPM_LINE can be input or output, additional check is needed in order to determine if the widget is connected as input or output. When checking for connected outputs, if the widget is line, than check if the sources list is not empty (line is connected as output) For input endpoint check, when the widget is line, also check if the sinks list is not empty (line is connected as input).

| | | | | | | | | | | | | | | | | | | | | I'm skipping -rc2 because the -rc1 Makefile mistakenly said -rc2, so in order to avoid confusion, I'm jumping from -rc1 to -rc3. That way, when 'uname' (or an oops report) says 2.6.32-rc2, there's no confusion about whether people perhaps meant -rc1 or -rc2.

The intent is to lower power consumption to ride-out transient electrical and thermal emergencies, rather than powering off the server. On platforms that can save more power/performance via P-states, the platform will first exhaust P-states before forcing idle. However, the relative benefit of P-states vs. idle states is platform dependent, and thus this driver need not know or care about it. This driver does not use the kernel's CPU hot-plug mechanism because after the transient emergency is over, the system must be returned to its normal state, and hotplug would permanently break both cpusets and binding. So to force idle, the driver creates a power saving thread. The scheduler will migrate the thread to the preferred CPU. The thread has max priority and has SCHED_RR policy, so it can occupy one CPU. To save power, the thread will invoke the deep C-state entry instructions. To avoid starvation, the thread will sleep 5% of the time time for every second (current RT scheduler has threshold to avoid starvation, but if other CPUs are idle, the CPU can borrow CPU timer from other, which makes the mechanism not work here) Vaidyanathan Srinivasan has proposed scheduler enhancements to allow injecting idle time into the system. This driver doesn't depend on those enhancements, but could cut over to them when they are available. Peter Z. does not favor upstreaming this driver until the those scheduler enhancements are in place. However, we favor upstreaming this driver now because it is useful now, and can be enhanced over time.

In addition to this, in some cases, an additional write to the IO port has to be performed in order to properly decode the event received from the device. This generates another interrupt which may overlap with the previous one. In the future this is going to be important for properly decoding events.

So we can get rid of the ugly module parameters and the detect callbacks. This shrinks the binary module sizes by 36% and 46%, respectively.
