| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reuse code from clocksource to handle wall clock counter. Since wrapparound occurs, the audio timestamp is reinitialized to zero on a trigger. Synchronized linked devices will start counting from same reference to avoid any drift. Max buffer time is limited to 178 seconds to make sure wall clock counter does not overflow Wallclock timestamps are disabled on capture streams until we figure out how to handle digital inputs.

| | | | | | | | | | | | It turned out that the COMBO position fix mode is rather more harmful, and it got reverted (with the replacement of runtime->delay calculation) recently. Hence we can get rid of AZX_DCAPS_POSFIX_COMBO as well. It's still possible to pass this mode via position_fix module option, in case where this really helps on weird machines (who knows).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DMA Position in Buffer (DPIB) should be used for ring buffer management, while LPIB register provides information on the number of samples transfered on the link. The difference between the two pieces of information corresponds to hardware/DMA buffering. This patch reports this difference in runtime->delay, and removes the use of the COMBO mode on recent Intel hardware. Credits to Takashi Iwai for an initial patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SSYNC bits are typically used to start multiple streams synchronously. It makes sense to use them for a single stream for a more predictable startup sequence. The transfers only start once the DMA and FIFOs are ready. This results in a better correlation between timestamps and number of samples played. Credits to Kar Leong Wang for suggesting this improvement.

Since then I've been getting artifacts on playback, including repeated sounds on my Asus laptop. My hardware is Cougar Point which the commit log of c20c5a841cbe47f5b7812b57bd25397497e5fbc0 mentions as tested so POS_FIX_COMBO probably works in general but apparently it doesn't on Asus K53E therefore the need for the quirk.

However, for applications like PulseAudio that don't require period wake ups, this workaround is just superfluous. Thus better to disable it when no_period_wakeup is given in hw_params.

This state can be D3cold on platforms with ACPI PM support. And runtime PM can provide a gerneral sysfs interface for a system policy manager. Runtime PM support is based on current HDA power saving implementation. The user can enable runtime PM on platfroms that provide acceptable latency on transition from D3 to D0. Details: - When both power saving and runtime PM are enabled: -- If a codec supports 'stop-clock' in D3, it will request suspending the controller after it enters D3 and request resuming the controller before back to D0. Thus the controller will be suspended only when all codecs are suspended and support stop-clock in D3. -- User IO operations and HW wakeup signal can resume the controller back to D0. - If runtime PM is disabled, power saving just works as before. - If power saving is disabled, the controller won't be suspended because the power usage counter can never be 0. More about 'stop-clock' feature: If a codec can support targeted pass-through operations in D3 state when there is no BCLK present on the link, it will set CLKSTOP flag in the supported power states and report PS-ClkStopOk when entering D3 state. Please refer to HDA spec section 7.3.3.10 Power state and 7.3.4.12 Supported Power State.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This addresses an issue encountered when a pcm is opened while transitioning to low power state (codec->power_on == 1 && codec->power_transition == -1). Add snd_pcm_power_up_d3wait to hda_codec. This function is used to power up from azx_open as opposed to snd_hda_power_up used from codec_exec_verb. When powering up from azx_open, wait for pending power downs to complete, avoiding the power up continuing in parallel with the power down on the work queue. The specific issue seen was with the CS4210 codec, it powers off the ADC and DAC nid in its suspend handler. If it is re-opened before the ~100ms power down process completes, the ADC and DAC nid are initialized while powered down and audio is lost until another suspend/resume cycle.

The current behavior is for avoiding the system lockup by accessing the disabled GPU, but due to the recent change in VGA-switcheroo, it determines the state simply by checking with the default VGA device. This is the culprit. Now with the new vga_switcheroo_get_client_state(), we can know the initial state of the bound GPU, thus can determine the initial audio client state more correctly.
