2019-11-27ASoC: max98090: remove msleep in PLL unlocked workaroundTzung-Bi Shih
It was observed Baytrail-based chromebooks could cause continuous PLL unlocked when using playback stream and capture stream simultaneously. Specifically, starting a capture stream after started a playback stream. As a result, the audio data could corrupt or turn completely silent. As the datasheet suggested, the maximum PLL lock time should be 7 msec. The workaround resets the codec softly by toggling SHDN off and on if PLL failed to lock for 10 msec. Notably, there is no suggested hold time for SHDN off. On Baytrail-based chromebooks, it would easily happen continuous PLL unlocked if there is a 10 msec delay between SHDN off and on. Removes the msleep().

2019-11-27ASoC: wm8904: fix automatic sysclk configurationMichael Walle
The simple-card tries to signal the codec to disable rate constraints, see commit 2458adb8f92a ("SoC: simple-card-utils: set 0Hz to sysclk when shutdown"). This wasn't handled by the codec, instead it would set the FLL frequency to 0Hz which isn't working. Since we don't have any rate constraints just ignore this request.

2019-11-27ASoC: AMD: Enable clk in startup intead of hw_paramsYu-Hsuan Hsu
Some usages only call startup and shutdown without setting hw_params (e.g. arecord --dump-hw-params). If we don't enable clk in startup, it will cause ref count error because the clk will be disabled in shutdown. For this reason, we should move enabling clk from hw_params to startup. In addition, the hw_params is fixed in this driver(48000 rate, 2 channels, S16_LE format) so we don't need to change the clk rate after the hw_params is set.

Static analysis tools (cppcheck and PVS Studio) report an error in loopback_snd_timer_period_elapsed() regarding dpcm_play pointer dereference earlier than its null-check. And although this is a result of a formal check, and the pointer correctness is also protected by having a corresponding bit set in the "running" mask, re-ordering of the lines can imake the code even formally correct and eliminate those static analysis error reports.

2019-11-22ALSA: aloop: Remove redundant locking in timer open functionAndrew Gabbasov
loopback_parse_timer_id() uses snd_card_ref(), that can lock on mutex, also snd_timer_instance_new() uses non-atomic allocation, that can sleep. So, both functions can not be called from loopback_snd_timer_open() with cable->lock spinlock locked. Moreover, most part of loopback_snd_timer_open() function body works when the opposite stream of the same cable does not yet exist, and the current stream is not yet completely open and can't be running, so existing locking of loopback->cable_lock mutex is enough to protect from conflicts with simultaneous opening or closing.

The old Nvidia chips have multiple HD-audio codecs on the same HD-audio controller, and this doesn't work as expected with the current audio component binding that is implemented under the one-codec-per- controller assumption; at the probe time, the driver leads to several kernel WARNING messages. For the proper support, we may change the pin2port and port2pin to traverse the codec list per the given pin number, but this needs more development and testing. As a quick workaround, instead, this patch drops the binding in the audio side for these legacy chips since the audio component support in nouveau graphics driver is still not merged (hence it's basically unused).

2019-11-20ALSA: pcm: Add card sync_irq fieldTakashi Iwai
Many PCI and other drivers performs snd_pcm_period_elapsed() simply in its interrupt handler, so the sync_stop operation is just to call synchronize_irq(). Instead of putting this call multiple times, introduce the common card->sync_irq field. When this field is set, PCM core performs synchronize_irq() for sync-stop operation. Each driver just needs to copy its local IRQ number to card->sync_irq, and that's all we need.

2019-11-20ALSA: pcm: Add the support for sync-stop operationTakashi Iwai
The standard programming model of a PCM sound driver is to process snd_pcm_period_elapsed() from an interrupt handler. When a running stream is stopped, PCM core calls the trigger-STOP PCM ops, sets the stream state to SETUP, and moves on to the next step. This is performed in an atomic manner -- this could be called from the interrupt context, after all. The problem is that, if the stream goes further and reaches to the CLOSE state immediately, the stream might be still being processed in snd_pcm_period_elapsed() in the interrupt context, and hits a NULL dereference. Such a crash happens because of the atomic operation, and we can't wait until the stream-stop finishes. For addressing such a problem, this commit adds a new PCM ops, sync_stop. This gets called at the appropriate places that need a sync with the stream-stop, i.e. at hw_params, prepare and hw_free. Some drivers already have a similar mechanism implemented locally, and we'll refactor the code later.

2019-11-20ALSA: pcm: Allow NULL ioctl opsTakashi Iwai
Currently PCM ioctl ops is a mandatory field but almost all drivers simply pass snd_pcm_lib_ioctl. For simplicity, allow to set NULL in the field and call snd_pcm_lib_ioctl() as default. Link: https://lore.kernel.org/r/20191117085308.23915-4-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-11-20ALSA: pcm: Introduce managed buffer allocation modeTakashi Iwai
This patch adds the support for the feature to automatically allocate and free PCM buffers, so called "managed buffer allocation" mode. It's set up via new PCM helpers, snd_pcm_set_managed_buffer() and snd_pcm_set_managed_buffer_all(), both of which correspond to the existing preallocator helpers, snd_pcm_lib_preallocate_pages() and snd_pcm_lib_preallocate_pages_for_all(). When the new helper is used, it not only performs the pre-allocation of buffers, but also it manages to call snd_pcm_lib_malloc_pages() before the PCM hw_params ops and snd_lib_pcm_free() after the PCM hw_free ops inside PCM core, respectively. This allows drivers to drop the explicit calls of the memory allocation / release functions, and it will be a good amount of code reduction in the end of this patch series. When the PCM substream is set to the managed buffer allocation mode, the managed_buffer_alloc flag is set in the substream object. Since some drivers want to know when a buffer is newly allocated or re-allocated at hw_params callback (e.g. want to set up the additional stuff for the given buffer only at allocation time), now PCM core turns on buffer_changed flag when the buffer has changed. The standard conversions to use the new API will be straightforward: - Replace snd_pcm_lib_preallocate*() calls with the corresponding snd_pcm_set_managed_buffer*(); the arguments should be unchanged - Drop superfluous snd_pcm_lib_malloc() and snd_pcm_lib_free() calls; the check of snd_pcm_lib_malloc() returns should be replaced with the check of runtime->buffer_changed flag. - If hw_params or hw_free becomes empty, drop them from PCM ops Link: https://lore.kernel.org/r/20191117085308.23915-2-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-11-20ALSA: aloop: Support runtime change of snd_timer via info interfaceAndrew Gabbasov
Show and change sound card timer source with read-write info file in proc filesystem. Initial string can still be set as module parameter. The timer source string value can be changed at any time, but it is latched by PCM substream open callback (the first one for a particular cable). At this point it is actually used, that is the string is parsed, and the timer is looked up and opened. The timer source is set for a loopback card (the same as initial setting by module parameter), but every cable uses the value, current at the moment of open. Setting the value to empty string switches the timer to jiffies.

2019-11-20ALSA: aloop: Support selection of snd_timer instead of jiffiesTimo Wischer
to do synchronous audio forwarding between hardware sound card and aloop devices. Such an audio route could look like the following: Sound card -> Loopback application -> ALSA loop device -> arecord In this case the loopback device should use the sound timer of the sound card. Without this patch the loopback application has to implement an adaptive sample rate converter to align the different clocks of the different ALSA devices. The used timer can be selected by referring to a sound card, its device and subdevice, when loading the module: $ modprobe snd_aloop enable=1 timer_source=[<card>[.<dev>[.<subdev>]]] <card> is the name (id) of the sound card or a card number. <dev> and <subdev> are device and subdevice numbers (defaults are 0). Empty string as a value of timer_source= parameter enables previous functionality (using jiffies timer).
