2023-12-13ALSA: pcm: fix out-of-bounds in snd_pcm_state_namesJason Zhang
commit 2b3a7a302c9804e463f2ea5b54dc3a6ad106a344 upstream. The pcm state can be SNDRV_PCM_STATE_DISCONNECTED at disconnect callback, and there is not an entry of SNDRV_PCM_STATE_DISCONNECTED in snd_pcm_state_names. This patch adds the missing entry to resolve this issue. cat /proc/asound/card2/pcm0p/sub0/status That results in stack traces like the following: [ 99.702732][ T5171] Unexpected kernel BRK exception at EL1 [ 99.702774][ T5171] Internal error: BRK handler: f2005512 [#1] PREEMPT SMP [ 99.703858][ T5171] Modules linked in: bcmdhd(E) (...)

commit a337c355719c42a6c5b67e985ad753590ed844fb upstream. It's been reported that the runtime PM on KONTRON SinglePC (PCI SSID 1734:1232) caused a stall of playback after a bunch of invocations. (FWIW, this looks like an timing issue, and the stall happens rather on the controller side.) As a workaround, disable the default power-save on this platform.

2023-11-28ALSA: info: Fix potential deadlock at disconnectionTakashi Iwai
commit c7a60651953359f98dbf24b43e1bf561e1573ed4 upstream. As reported recently, ALSA core info helper may cause a deadlock at the forced device disconnection during the procfs operation. The proc_remove() (that is called from the snd_card_disconnect() helper) has a synchronization of the pending procfs accesses via wait_for_completion(). Meanwhile, ALSA procfs helper takes the global mutex_lock(&info_mutex) at both the proc_open callback and snd_card_info_disconnect() helper. Since the proc_open can't finish due to the mutex lock, wait_for_completion() never returns, either, hence it deadlocks. TASK#1 TASK#2 proc_reg_open() takes use_pde() snd_info_text_entry_open() snd_card_disconnect() snd_info_card_disconnect() takes mutex_lock(&info_mutex) proc_remove() wait_for_completion(unused_pde) ... waiting task#1 closes mutex_lock(&info_mutex) => DEADLOCK This patch is a workaround for avoiding the deadlock scenario above. The basic strategy is to move proc_remove() call outside the mutex lock. proc_remove() can work gracefully without extra locking, and it can delete the tree recursively alone. So, we call proc_remove() at snd_info_card_disconnection() at first, then delete the rest resources recursively within the info_mutex lock. After the change, the function snd_info_disconnect() doesn't do disconnection by itself any longer, but it merely clears the procfs pointer. So rename the function to snd_info_clear_entries() for avoiding confusion. The similar change is applied to snd_info_free_entry(), too. Since the proc_remove() is called only conditionally with the non-NULL entry->p, it's skipped after the snd_info_clear_entries() call.

2023-09-23ASoC: da7219: Flush pending AAD IRQ when suspendingDmytro Maluka
[ Upstream commit 91e292917dad64ab8d1d5ca2ab3069ad9dac6f72 ] da7219_aad_suspend() disables jack detection, which should prevent generating new interrupts by DA7219 while suspended. However, there is a theoretical possibility that there is a pending interrupt generated just before suspending DA7219 and not handled yet, so the IRQ handler may still run after DA7219 is suspended. To prevent that, wait until the pending IRQ handling is done. This patch arose as an attempt to fix the following I2C failure occurring sometimes during system suspend or resume: [ 355.876211] i2c_designware i2c_designware.3: Transfer while suspended [ 355.876245] WARNING: CPU: 2 PID: 3576 at drivers/i2c/busses/i2c-designware-master.c:570 i2c_dw_xfer+0x411/0x440 ...

2023-08-30ALSA: pcm: Fix potential data race at PCM memory allocation helpersTakashi Iwai
[ Upstream commit bd55842ed998a622ba6611fe59b3358c9f76773d ] The PCM memory allocation helpers have a sanity check against too many buffer allocations. However, the check is performed without a proper lock and the allocation isn't serialized; this allows user to allocate more memories than predefined max size. Practically seen, this isn't really a big problem, as it's more or less some "soft limit" as a sanity check, and it's not possible to allocate unlimitedly. But it's still better to address this for more consistent behavior. The patch covers the size check in do_alloc_pages() with the card->memory_mutex, and increases the allocated size there for preventing the further overflow. When the actual allocation fails, the size is decreased accordingly.

2023-08-30ALSA: pcm: Use SG-buffer only when direct DMA is availableTakashi Iwai
[ Upstream commit 3ad796cbc36a7bc8bfd4de191d791b9490bc112b ] The DMA-coherent SG-buffer is tricky to use, as it does need the mapping. It used to work stably on x86 over years (and that's why we had enabled SG-buffer on solely x86) with the default mmap handler and vmap(), but our luck seems no forever success. The chance of breakage is high when the special DMA handling is introduced in the arch side. In this patch, we change the buffer allocation to use the SG-buffer only when the device in question is with the direct DMA. It's a bit hackish, but it's currently the only condition that may work (more or less) reliably with the default mmap and vmap() for mapping the pages that are deduced via virt_to_page(). In theory, we can apply the similar hack in the sound/core memory allocation helper, too; but it's used by SOF for allocating SG pages without re-mapping via vmap() or mmap, and it's fine to use it in that way, so let's keep it and adds the workaround in PCM side.

2023-08-30ALSA: pcm: Set per-card upper limit of PCM buffer allocationsTakashi Iwai
[ Upstream commit d4cfb30fce03093ad944e0b44bd8f40bdad5330e ] Currently, the available buffer allocation size for a PCM stream depends on the preallocated size; when a buffer has been preallocated, the max buffer size is set to that size, so that application won't re-allocate too much memory. OTOH, when no preallocation is done, each substream may allocate arbitrary size of buffers as long as snd_pcm_hardware.buffer_bytes_max allows -- which can be quite high, HD-audio sets 1GB there. It means that the system may consume a high amount of pages for PCM buffers, and they are pinned and never swapped out. This can lead to OOM easily. For avoiding such a situation, this patch adds the upper limit per card. Each snd_pcm_lib_malloc_pages() and _free_pages() calls are tracked and it will return an error if the total amount of buffers goes over the defined upper limit. The default value is set to 32MB, which should be really large enough for usual operations. If larger buffers are needed for any specific usage, it can be adjusted (also dynamically) via snd_pcm.max_alloc_per_card option. Setting zero there means no chceck is performed, and again, unlimited amount of buffers are allowed.

[ Upstream commit c1f848f12103920ca165758aedb1c10904e193e1 ] When the tdm lane mask is computed, the driver currently fills the 1st lane before moving on to the next. If the stream has less channels than the lanes can accommodate, slots will be disabled on the last lanes. Unfortunately, the HW distribute channels in a different way. It distribute channels in pair on each lanes before moving on the next slots. This difference leads to problems if a device has an interface with more than 1 lane and with more than 2 slots per lane. For example: a playback interface with 2 lanes and 4 slots each (total 8 slots - zero based numbering) - Playing a 8ch stream: - All slots activated by the driver - channel #2 will be played on lane #1 - slot #0 following HW placement - Playing a 4ch stream: - Lane #1 disabled by the driver - channel #2 will be played on lane #0 - slot #2 This behaviour is obviously not desirable. Change the way slots are activated on the TDM lanes to follow what the HW does and make sure each channel always get mapped to the same slot/lane.

2023-08-30ALSA: hda: Fix unhandled register update during auto-suspend periodTakashi Iwai
[ Upstream commit 81302b1c7c997e8a56c1c2fc63a296ebeb0cd2d0 ] It's reported that the recording started right after the driver probe doesn't work properly, and it turned out that this is related with the codec auto-suspend. Namely, after the probe phase, the usage count goes zero, and the auto-suspend is programmed, but the codec is kept still active until the auto-suspend expiration. When an application (e.g. alsactl) updates the mixer values at this moment, the values are cached but not actually written. Then, starting arecord thereafter also results in the silence because of the missing unmute. The root cause is the handling of "lazy update" mode; when a mixer value is updated *after* the suspend, it should update only the cache and exits. At the resume, the cached value is written to the device, in turn. The problem is that the current code misinterprets the state of auto-suspend as if it were already suspended. Although we can add the check of the actual device state after pm_runtime_get_if_in_use() for catching the missing state, this won't suffice; the second call of regmap_update_bits_check() will skip writing the register because the cache has been already updated by the first call. So we'd need fixes in two different places. OTOH, a simpler fix is to replace pm_runtime_get_if_in_use() with pm_runtime_get_if_active() (with ign_usage_count=true). This change implies that the driver takes the pm refcount if the device is still in ACTIVE state and continues the processing. A small caveat is that this will leave the auto-suspend timer. But, since the timer callback itself checks the device state and aborts gracefully when it's active, this won't be any substantial problem. Long story short: we address the missing register-write problem just by replacing the pm_runtime_*() call in snd_hda_keep_power_up().

2023-08-11ASoC: cs42l51: fix driver to properly autoload with automatic module loadingThomas Petazzoni
commit e51df4f81b02bcdd828a04de7c1eb6a92988b61e upstream. In commit 2cb1e0259f50 ("ASoC: cs42l51: re-hook of_match_table pointer"), 9 years ago, some random guy fixed the cs42l51 after it was split into a core part and an I2C part to properly match based on a Device Tree compatible string. However, the fix in this commit is wrong: the MODULE_DEVICE_TABLE(of, ....) is in the core part of the driver, not the I2C part. Therefore, automatic module loading based on module.alias, based on matching with the DT compatible string, loads the core part of the driver, but not the I2C part. And threfore, the i2c_driver is not registered, and the codec is not known to the system, nor matched with a DT node with the corresponding compatible string. In order to fix that, we move the MODULE_DEVICE_TABLE(of, ...) into the I2C part of the driver. The cs42l51_of_match[] array is also moved as well, as it is not possible to have this definition in one file, and the MODULE_DEVICE_TABLE(of, ...) invocation in another file, due to how MODULE_DEVICE_TABLE works. Thanks to this commit, the I2C part of the driver now properly autoloads, and thanks to its dependency on the core part, the core part gets autoloaded as well, resulting in a functional sound card without having to manually load kernel modules.

2023-07-27ALSA: jack: Fix mutex call in snd_jack_report()Takashi Iwai
[ Upstream commit 89dbb335cb6a627a4067bc42caa09c8bc3326d40 ] snd_jack_report() is supposed to be callable from an IRQ context, too, and it's indeed used in that way from virtsnd driver. The fix for input_dev race in commit 1b6a6fc5280e ("ALSA: jack: Access input_dev under mutex"), however, introduced a mutex lock in snd_jack_report(), and this resulted in a potential sleep-in-atomic. For addressing that problem, this patch changes the relevant code to use the object get/put and removes the mutex usage. That is, snd_jack_report(), it takes input_get_device() and leaves with input_put_device() for assuring the input_dev being assigned. Although the whole mutex could be reduced, we keep it because it can be still a protection for potential races between creation and deletion.

2023-07-27ASoC: es8316: Do not set rate constraints for unsupported MCLKsCristian Ciocaltea
[ Upstream commit 60413129ee2b38a80347489270af7f6e1c1de4d0 ] When using the codec through the generic audio graph card, there are at least two calls of es8316_set_dai_sysclk(), with the effect of limiting the allowed sample rates according to the MCLK/LRCK ratios supported by the codec: 1. During audio card setup, to set the initial MCLK - see asoc_simple_init_dai(). 2. Before opening a stream, to update MCLK, according to the stream sample rate and the multiplication factor - see asoc_simple_hw_params(). In some cases the initial MCLK might be set to a frequency that doesn't match any of the supported ratios, e.g. 12287999 instead of 12288000, which is only 1 Hz below the supported clock, as that is what the hardware reports. This creates an empty list of rate constraints, which is further passed to snd_pcm_hw_constraint_list() via es8316_pcm_startup(), and causes the following error on the very first access of the sound card: $ speaker-test -D hw:Analog,0 -F S16_LE -c 2 -t wav Broken configuration for playback: no configurations available: Invalid argument Setting of hwparams failed: Invalid argument Note that all subsequent retries succeed thanks to the updated MCLK set at point 2 above, which uses a computed frequency value instead of a reading from the hardware registers. Normally this would have mitigated the issue, but es8316_pcm_startup() executes before the 2nd call to es8316_set_dai_sysclk(), hence it cannot make use of the updated constraints. Since es8316_pcm_hw_params() performs anyway a final validation of MCLK against the stream sample rate and the supported MCLK/LRCK ratios, fix the issue by ensuring that sysclk_constraints list is only set when at least one supported sample rate is autodetected by the codec.

2023-07-27ASoC: es8316: Increment max value for ALC Capture Target Volume controlCristian Ciocaltea
[ Upstream commit 6f073429037cd79d7311cd8236311c53f5ea8f01 ] The following error occurs when trying to restore a previously saved ALSA mixer state (tested on a Rock 5B board): $ alsactl --no-ucm -f /tmp/asound.state store hw:Analog $ alsactl --no-ucm -I -f /tmp/asound.state restore hw:Analog alsactl: set_control:1475: Cannot write control '2:0:0:ALC Capture Target Volume:0' : Invalid argument According to ES8316 datasheet, the register at address 0x2B, which is related to the above mixer control, contains by default the value 0xB0. Considering the corresponding ALC target bits (ALCLVL) are 7:4, the control is initialized with 11, which is one step above the maximum value allowed by the driver: ALCLVL | dB gain -------+-------- 0000 | -16.5 0001 | -15.0 0010 | -13.5 .... | ..... 0111 | -6.0 1000 | -4.5 1001 | -3.0 1010 | -1.5 .... | ..... 1111 | -1.5 The tests performed using the VU meter feature (--vumeter=TYPE) of arecord/aplay confirm the specs are correct and there is no measured gain if the 1011-1111 range would have been mapped to 0 dB: dB gain | VU meter % --------+----------- -6.0 | 30-31 -4.5 | 35-36 -3.0 | 42-43 -1.5 | 50-51 0.0 | 50-51 Increment the max value allowed for ALC Capture Target Volume control, so that it matches the hardware default. Additionally, update the related TLV to prevent an artificial extension of the dB gain range.
