2025-05-21Add DAPM/ASoC helpers to create SDCA driversMark Brown
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>: Add helper functions to add DAPM widgets, routes, ALSA controls, and DAI drivers, these will be used to create SDCA function device drivers. This series should provide most of the core functionality needed to get a device registered and have a working DAPM graph within the device. There are some features that still need additional work, these are marked with FIXMEs in the code. The two main things are SDCA Clock Muxes (not used in our devices and needs some ASoC core work), and better support for more complex SDCA volume control definitions (our parts have fairly simple volumes, and SDCA has a large amount of flexibility in how the volume control is specified). The next steps in the process are to add helpers for the DAI ops themselves, some IRQ handling, and firmware download. And finally we should be able to actually add the SDCA class driver itself.

2025-05-21ALSA: qc_audio_offload: try to reduce address space confusionArnd Bergmann
uaudio_transfer_buffer_setup() allocates a buffer for the subs->dev device, and the returned address for the buffer is a CPU local virtual address that may or may not be in the linear mapping, as well as a DMA address token that is accessible by the USB device, and this in turn may or may not correspond to the physical address. The use in the driver however assumes that these addresses are the linear map and the CPU physical address, respectively. Both are nonportable here, but in the end only the virtual address gets used by converting it to a physical address that gets mapped into a second iommu. Make this more explicit by pulling the conversion out first and warning if it is not part of the linear map, and using the actual physical address to map into the iommu in place of the dma address that may already be iommu-mapped into the usb host.

2025-05-21ALSA: qc_audio_offload: avoid leaking xfer_buf allocationArnd Bergmann
The info->xfer_buf_cpu member is set to a NULL value because the allocation happens in a different function and is only assigned to the function argument but never passed back. Pass it by reference instead to have a handle that can actually be freed by the final usb_free_coherent() call.

2025-05-21ALSA: qc_audio_offload: rename dma/iova/va/cpu/phys variablesArnd Bergmann
While trying to understand a bug in the audio offload code, I had to spend extra time due to unfortunate nameing of local variables and struct members. Change these to more conventional names that reflect the actual usage: - pointers to the CPU virtual addresses of a dma buffer get a _cpu suffix to disambiguate them for MMIO virtual addresses - MMIO virtual addresses that are mapped explicitly through the IOMMU get a _iova suffix consistently, rather than a mix of iova and va. - DMA addresses (dma_addr_t) that are in a device address space (linear or IOMMU) get a _dma suffix in place of the _pa suffix. - CPU physical (phys_addr_t) addresses get a _pa suffix. There is still a mixup with dma addresses here that I address in another patch. No functional changes are intended here.

2025-05-20ASoC: SDCA: Create ALSA controls from DisCoCharles Keepax
Use the previously parsed DisCo information from ACPI to create the ALSA controls required by an SDCA Function. This maps all User and Application level SDCA Controls to ALSA controls. Typically controls marked with those access levels are just volumes and mutes. SDCA defines volume controls as an integer in 1/256ths of a dB and then provides a mechanism to specify what values are valid (range templates). Currently only a simple case of a single linear volume range with a power of 2 step size is supported. This allows the code to expose the volume control using a simple shift. This will need expanded in the future, to support more complex ranges and probably also some additional control types but this should be sufficient to for a first pass. For non-dataport terminal widgets also add a pin switch to allow that endpoint to be turned on/off.

2025-05-20ASoC: SDCA: Create DAPM widgets and routes from DisCoCharles Keepax
Use the previously parsed DisCo information from ACPI to create DAPM widgets and routes representing a SDCA Function. For the most part SDCA maps well to the DAPM abstractions. The primary point of interest is the SDCA Power Domain Entities (PDEs), which actually control the power status of the device. Whilst these PDEs are the primary widgets the other parts of the SDCA graph are added to maintain a consistency with the hardware abstract, and allow routing to take effect. As for the PDEs themselves the code currently only handle PS0 and PS3 (basically on and off), the two intermediate power states are not commonly used and don't map well to ASoC/DAPM. Other minor points of slightly complexity include, the Group Entities (GEs) these set the value of several other controls, typically Selector Units (SUs) for enabling a cetain jack configuration. Multiple SUs being controlled by a GE are easily modelled creating a single control and sharing it among the controlled muxes. SDCA also has a slight habit of having fully connected paths, relying more on activating the PDEs to enable functionality. This doesn't map quite so perfectly to DAPM which considers the path a reason to power the PDE. Whilst in the current specification Mixer Units are defined as fixed-function, in DAPM we create a virtual control for each input (which defaults to connected). This allows paths to be connected/disconnected, providing a more ASoC style approach to managing the power. PIN_SWITCHs will also be added for non-dataport terminal entities in a later patch along with the other ALSA controls, providing greater flexibility in power management. A top level helper sdca_asoc_populate_component() is exported that counts and allocates everything, however, the intermediate counting and population functions are also exported. This will allow end drivers to do allocation and add custom handling, which is probably fairly likely for the early SDCA devices. Clock muxes are currently not fully supported, so some future work will also be required there.

2025-05-19ALSA: usb-audio: Kill timer properly at removalTakashi Iwai
The USB-audio MIDI code initializes the timer, but in a rare case, the driver might be freed without the disconnect call. This leaves the timer in an active state while the assigned object is released via snd_usbmidi_free(), which ends up with a kernel warning when the debug configuration is enabled, as spotted by fuzzer. For avoiding the problem, put timer_shutdown_sync() at snd_usbmidi_free(), so that the timer can be killed properly. While we're at it, replace the existing timer_delete_sync() at the disconnect callback with timer_shutdown_sync(), too.

2025-05-16ASoC: soc-utils: Check string pointer validity in snd_soc_dlc_is_dummy()Chen-Yu Tsai
In the recently added snd_soc_dlc_is_dummy(), the helper uses the .name and .dai_name fields without checking their validity. For .name, this field is NULL if the component is matched by .of_node instead. In fact, only one of these fields may be set. This caused a NULL pointer dereference on MediaTek MT8195 and MT8188 platforms with the subsequent conversion to snd_soc_dlc_is_dummy() in their machine drivers. The codecs are all matches through the device tree, so their .name fields are empty. For .dai_name, there are cases where this field is empty, such as for the following component definitions: #define COMP_EMPTY() { } #define COMP_PLATFORM(_name) { .name = _name } #define COMP_AUX(_name) { .name = _name } #define COMP_CODEC_CONF(_name) { .name = _name } Or the single link CPU DAI case in the simple audio card family, as covered by simple_util_canonicalize_cpu(), in which the .dai_name field is explicitly cleared. To fix this, check the validity of the fields before using them in string comparison.

2025-05-16ALSA: pcm: Fix race of buffer access at PCM OSS layerTakashi Iwai
The PCM OSS layer tries to clear the buffer with the silence data at initialization (or reconfiguration) of a stream with the explicit call of snd_pcm_format_set_silence() with runtime->dma_area. But this may lead to a UAF because the accessed runtime->dma_area might be freed concurrently, as it's performed outside the PCM ops. For avoiding it, move the code into the PCM core and perform it inside the buffer access lock, so that it won't be changed during the operation.

2025-05-15ASoC: mediatek: mt8183-afe-pcm: Shorten source codeMark Brown
Merge series from Chen-Yu Tsai <wenst@chromium.org>: This series is meant as an example on how to use macros and range cases to shorten the MediaTek audio frontend drivers. The drivers have large tables describing the registers and register fields for every supported audio DMA interface. (Some are actually skipped!) There's a lot of duplication which can be eliminated using macros. This should serve as a reference for the MT8196 AFE driver that I had commented on. The three patches tackle separate tables in the driver. The remaining one that could be tackled is the list of DAIs; but that one has more differences between each entry, so I haven't done it yet.
