Thus, each callback can't know it is called for which component. Each callback currently is getting "component" by using snd_soc_rtdcom_lookup() with driver name. It works today, but, will not work in the future if we support multi CPU/Codec/Platform, because 1 rtd might have multiple same driver name component. To solve this issue, each callback need to be called with component. This patch adds new pcm_construct/pcm_destruct with "component" parameter.

Actually, we cover three drivers: * Legacy HDA * Intel SST * Intel Sound Open Firmware (SOF) All those drivers registers similar PCI IDs, so the first driver probed from the PCI stack can win. But... it is not guaranteed that the correct driver wins. This commit changes Intel's NHLT ACPI module to a common DSP probe module for the Intel's hardware. All above sound drivers calls this code. The user can force another behaviour using the module parameter 'dsp_driver' located in the 'snd-intel-dspcfg' module. This change allows to add specific dmi checks for the specific systems. The examples are taken from the pull request: https://github.com/thesofproject/linux/pull/927 Tested on Lenovo Carbon X1 7th gen.

The relationship image is like below rtdcom rtdcom rtdcom component component component rtd->component_list -> list -> list -> list ... Here, the pointer get via normal link list is rtdcom, Thus, current for_each loop is like below, and need to get component via rtdcom->component for_each_rtdcom(rtd, rtdcom) { component = rtdcom->component; ... } but usually, user want to get pointer from for_each_xxx is component directly, like below. for_each_rtd_component(rtd, rtdcom, component) { ... } This patch expands list_for_each_entry manually, and enable to get component directly from for_each macro. Because of it, the macro becoming difficult to read, but macro itself becoming useful.

This implementation works fine with snd_hda_intel.c as PCM topology is fully managed within the single driver. When the HDA codec driver is used from ASoC components, the concept of backup PCMs no longer fits. For ASoC topologies, the physical HDMI converters are presented as backend DAIs and these should match with hardware capabilities. The ASoC topology may define arbitrary PCMs (i.e. frontend DAIs) and have processing elements before eventual routing to the HDMI BE DAIs. With backup PCMs, the link between FE and BE DAIs would become dynamic and change when monitors are (un)plugged. This would lead to modifying the topology every time hotplug events happen, which is not currently possible in ASoC and there does not seem to be any obvious benefits from this design. To overcome above problems and enable the HDMI driver to be used from ASoC, this patch adds a new mode (mst_no_extra_pcms flags) to patch_hdmi.c. In this mode, the codec driver does not assume the backup PCMs to be created.

This is aligned with how other HDA codecs are already handled. When snd-hda-codec-hdmi is used, the PCM device numbers are parsed from card topology and passed to the codec driver. This needs to be done at runtime as topology changes may affect PCM device allocation.

But to reduce duplicated code, it should be used from _dais(), too. Because of topology side specific reason, it is calling snd_soc_dapm_new_dai_widgets(), but it is not needed _dais() side. This patch factorizes snd_soc_register_dai() to topology / _dais() common part, and topology specific part. And do topology specific part at soc-topology.

A new type, SNDRV_DMA_TYPE_VMALLOC was added. The vmalloc buffer has been already supported in the PCM via a few own helper functions, but the user sometimes get confused and misuse them. With this patch, the whole buffer management is integrated into the memalloc core, so they can be used in a sole common way.

In both the user-timer and the sequencer-timer code, they do manually set up the callbacks after calling snd_timer_open(). This has a potential risk of race when the timer instance is added to the already running timer target, as the callback might get triggered during setting up the callback itself. This patch tries to address it by changing the API usage slightly: - An empty timer instance is created at first via the new function snd_timer_instance_new(). This object isn't linked to the timer list yet. - The caller sets up the callbacks and others stuff for the new timer instance. - The caller invokes snd_timer_open() with this instance, so that it's linked to the target timer. For closing, do similarly: - Call snd_timer_close(). This unlinks the timer instance from the timer list. - Free the timer instance via snd_timer_instance_free() after that.

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 --- include/sound/pcm.h | 8 +++++ sound/core/pcm_memory.c | 83 +++++++++++++++++++++++++++++++++++++++++-------- sound/core/pcm_native.c | 12 +++++++ 3 files changed, 90 insertions(+), 13 deletions(-) (limited to 'include') diff --git a/include/sound/pcm.h b/include/sound/pcm.h index 2c0aa884f5f1..253d15c61ce2 100644 --- a/include/sound/pcm.h +++ b/include/sound/pcm.h @@ -414,6 +414,7 @@ struct snd_pcm_runtime { size_t dma_bytes;

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.

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.
