2024-02-23ALSA: pcm: clarify and fix default msbits value for all formatsJaroslav Kysela
Return used most significant bits from sample bit-width rather than the whole physical sample word size. The starting bit offset is defined in the format itself. The behaviour is not changed for 32-bit formats like S32_LE. But with this change - msbits value 24 instead 32 is returned for 24-bit formats like S24_LE etc. Also, commit 2112aa034907 ("ALSA: pcm: Introduce MSBITS subformat interface") compares sample bit-width not physical sample bit-width to reset MSBITS_MAX bit from the subformat bitmask. Probably no applications are using msbits value for other than S32_LE/U32_LE formats, because no drivers are reducing msbits value for other formats (with the msb offset) at the moment. For sanity, increase PCM protocol version, letting the user space to detect the changed behaviour.

2023-11-27ALSA: hda: Upgrade stream-format infrastructureCezary Rojewski
Introduce a set of functions that ultimately facilite SDxFMT-related calculations in atomic manner: First, introduce snd_pcm_subformat_width() and snd_pcm_hw_params_bits() helpers that separate the base functionality from the HDAudio-specific one. snd_hdac_format_normalize() - format converter. S20_LE, S24_LE and their unsigned and BE friends are invalid from HDAudio perspective but still can be specified as function argument due to compatibility reasons. snd_hdac_stream_format_bits() - obtain just the bits-per-sample value. Does not ignore subformat and msbits parameters. snd_hdac_stream_format() and snd_hdac_spdif_stream_format() - obtain the SDxFMT value given the audio format parameters. The former is stripped away of spdif-related information. Useful for users that do not care about them.

2023-11-27ALSA: pcm: Introduce MSBITS subformat interfaceJaroslav Kysela
Improve granularity of format selection for S32/U32 formats by adding constants representing 20, 24 and MAX most significant bits. The MAX means the maximum number of significant bits which can the physical format hold. For 32-bit formats, MAX is related to 32 bits. For 8-bit formats, MAX is related to 8 bits etc. As there is only one user currently (format S32_LE), subformat is represented by a simple u32 and stores flags only for that one user alone. The approach of subformat being part of struct snd_pcm_hardware is a compromise between ALSA and ASoC allowing for hw_params-intersection code to be alloc/free-less while not adding any new responsibilities to ASoC runtime structures.

2023-11-09ALSA: info: Fix potential deadlock at disconnectionTakashi Iwai
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.

2023-09-12ALSA: seq: Avoid delivery of events for disabled UMP groupsTakashi Iwai
ALSA sequencer core still delivers events to the disabled UMP Group, leaving this handling to the device. But it's rather risky and it's easy to imagine that such an unexpected event may screw up the device firmware. This patch avoids the superfluous event deliveries by setting the group_filter of the UMP client as default, and evaluate the group_filter properly at delivery from non-UMP clients. The grouop_filter is updated upon the dynamic UMP Function Block updates, so that it follows the change of the disabled UMP Groups, too.

2023-08-24ALSA: ump: Don't create unused substreams for static blocksTakashi Iwai
When the UMP Endpoint is declared as "static", that is, no dynamic reassignment of UMP Groups, it makes little sense to expose always all 16 groups with 16 substreams. Many of those substreams are disabled groups, hence they are useless, but applications don't know it and try to open / access all those substreams unnecessarily. This patch limits the number of UMP legacy rawmidi substreams only to the active groups. The behavior is changed only for the static endpoint (i.e. devices without UMP v1.1 feature implemented or with the static block flag is set).

2023-08-18ALSA: pcm: Add copy ops with iov_iterTakashi Iwai
iov_iter is a universal interface to copy the data chunk from/to user-space and kernel in a unified manner. This API can fit for ALSA PCM copy ops, too; we had to split to copy_user and copy_kernel in the past, and those can be unified to a single ops with iov_iter. This patch adds a new PCM copy ops that passes iov_iter for copying both kernel and user-space in the same way. This patch touches only the ALSA PCM core part, and the actual users will be replaced in the following patches. The expansion of iov_iter is done in the PCM core right before calling each copy callback. It's a bit suboptimal, but I took this now as it's the most straightforward replacement. The more conversion to iov_iter in the caller side is a TODO for future. As of now, the old copy_user and copy_kernel ops are still kept. Once after all users are converted, we'll drop the old copy_user and copy_kernel ops, too.

So far we use the embedded struct device for each PCM substreams in struct snd_pcm.

As a workaround, detach the struct device from the snd_pcm object by allocating via the new snd_device_alloc() helper. A caveat is that we store the PCM substream pointer to drvdata since the device resume and others require the access to it. This patch is based on the fix Curtis posted initially.

We've got a bunch of new drivers in here, a bit of core work from Morimoto-san and quite a lot of janitorial work. There's several updates that pull in changes from other subsystems in order to build on them: - An adaptor to allow use of IIO DACs and ADCs in ASoC which pulls in some IIO changes. - Create a library function for intlog10() and use it in the NAU8825 driver. - Include the ASoC tests, including the topology tests, in the default KUnit full test coverage. This also involves enabling UML builds of ALSA since that's the default KUnit test environment which pulls in the addition of some stubs to the driver. - More factoring out from Morimoto-san. - Convert a lot of drivers to use the more modern maple tree register cache. - Support for AMD machines with MAX98388 and NAU8821, Cirrus Logic CS35L36, Intel AVS machines with ES8336 and RT5663 and NXP i.MX93.
