* ALSA: hdsp: remove redundant assignment to pointer kctlColin Ian King2022-05-091-1/+1
| | | | | | | | | | | | | | | Pointer kctl is being assigned a value that is not being read, buf is being re-assigned later. The assignment is redundant and can be removed.

* ALSA: rme9652: Fix the missing snd_card_free() call at probe errorTakashi Iwai2022-04-121-2/+6
| | | | | | | | | | | | | | | | The previous cleanup with devres may lead to the incorrect release orders at the probe error handling due to the devres's nature. Until we register the card, snd_card_free() has to be called at first for releasing the stuff properly when the driver tries to manage and release the stuff via card->private_free(). This patch fixes it by calling snd_card_free() manually on the error from the probe callback.

* ALSA: pci: rme: Fix unaligned buffer addressesTakashi Iwai2021-11-082-36/+46
| | | | | | | | | | | | | | | | | | | | The recent fix for setting up the DMA buffer type on RME drivers tried to address the non-standard memory managements and changed the DMA buffer information to the standard snd_dma_buffer object that is allocated at the probe time. However, I overlooked that the RME drivers handle the buffer addresses based on 64k alignment, and the previous conversion broke that silently. This patch is an attempt to fix the regression. The snd_dma_buffer objects are copied to the original data with the correction to the aligned accesses, and those are passed to snd_pcm_set_runtime_buffer() helpers instead. The original snd_dma_buffer objects are managed by devres, hence they'll be released automagically.

* ALSA: pci: rme: Set up buffer type properlyTakashi Iwai2021-08-092-8/+4
| | | | | | | | | | | | | | | | | Although the regression of the mmap was fixed in the recent commit dc0dc8a73e8e ("ALSA: pcm: Fix mmap breakage without explicit buffer setup"), RME9652 and HDSP drivers have still potential issues with their mmap handling. Namely, they use the default mmap handler without the standard buffer preallocation, and PCM core wouldn't use the coherent DMA mapping. It's practically OK on x86, but on some exotic architectures, it wouldn't work. This patch addresses the potential breakage by replacing the buffer setup with the proper macro. It also simplifies the source code, too. Link: https://lore.kernel.org/r/20210809071829.22238-3-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

A new control layer registration is introduced which allows to run additional operations on top of the elementary ALSA sound controls. A new control access group (three bits in the access flags) was introduced to carry the LED group information for the sound controls. The low-level sound drivers can just mark those controls using this access group. This information is not exported to the user space, but user space can manage the LED sound control associations through sysfs (last patch) per Mark's request. It makes things fully configurable in the kernel and user space (UCM). The actual state ('route') evaluation is really easy (the minimal value check for all channels / controls / cards). If there's more complicated logic for a given hardware, the card driver may eventually export a new read-only sound control for the LED group and do the logic itself. The new LED trigger control code is completely separated and possibly optional (there's no symbol dependency). The full code separation allows eventually to move this LED trigger control to the user space in future. Actually it replaces the already present functionality in the kernel space (HDA drivers) and allows a quick adoption for the recent hardware (ASoC codecs including SoundWire). snd_ctl_led 24576 0 The sound driver implementation is really easy: 1) call snd_ctl_led_request() when control LED layer should be automatically activated / it calls module_request("snd-ctl-led") on demand / 2) mark all related kcontrols with SNDRV_CTL_ELEM_ACCESS_SPK_LED or SNDRV_CTL_ELEM_ACCESS_MIC_LED Link: https://lore.kernel.org/r/20210317172945.842280-1-perex@perex.cz Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: hdsp: hardware output loopbackJasmin Fazlic2021-02-021-1/+73
| | | | | | | | | | | | | | | | | | | | Output loopback is a feature where you can record what you hear. The HDSP series of the RME interfaces provides this functionality at the hardware level and this patch exposes controls to enable or disable it per output (playback) channel. This probably works on other cards but due to a lack of hardware it is only tested and enabled for the HDSP9632 card with this patch. Should this patch be accepted a separate patch will be posted to https://github.com/alsa-project/alsa-tools/tree/master/hdspmixer which adds "LPBK" buttons to each output in the playback strip for the user to be able to control this feature from the user land. Users from Windows tool TotalMixFX should be familiar with this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The firmware loading ioctl that is implemented for hdsp hwdep device takes the reference of the address pointer, hence the current code is rather confusing. Also, due to the recent change in uapi header, sparse also complains about the cast. This patch tries to improve the readability by converting the straightforward copy_from_user of the whole struct (which contains only the pointer).

Here we go, some highlights: Core: - Finally y2038 support landed to ALSA ABI; some ioctls have been extended and lots of tricks were applied - Applying the new managed PCM buffer API to all drivers; the API itself was already merged in 5.5 - The already deprecated dimension support in ALSA control API is dropped completely now - Verification of ALSA control elements to catch API misuses ASoC: - Further code refactorings and moving things to the component level - Lots of updates and improvements on SOF / Intel drivers; now including common HDMI driver and SoundWire support - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015 and RT1308 HD-audio: - Improved ring-buffer communications using waitqueue - Drop the superfluous buffer preallocation on x86 Others: - Many code cleanups, mostly constifications over the whole tree - USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix - FireWire: code refactoring for oxfw and dice drivers" * tag 'sound-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (638 commits) ALSA: usb-audio: add quirks for Line6 Helix devices fw>=2.82 ALSA: hda: Add Clevo W65_67SB the power_save blacklist ASoC: soc-core: remove null_snd_soc_ops ASoC: soc-pcm: add soc_rtd_trigger() ASoC: soc-pcm: add soc_rtd_hw_free() ASoC: soc-pcm: add soc_rtd_hw_params() ASoC: soc-pcm: add soc_rtd_prepare() ASoC: soc-pcm: add soc_rtd_shutdown() ASoC: soc-pcm: add soc_rtd_startup() ASoC: rt1015: add rt1015 amplifier driver ASoC: madera: Correct some kernel doc ASoC: topology: fix soc_tplg_fe_link_create() - link->dobj initialization order ASoC: Intel: skl_hda_dsp_common: Fix global-out-of-bounds bug ASoC: madera: Correct DMIC only input hook ups ALSA: cs46xx: fix spelling mistake "to" -> "too" ALSA: hda - Add docking station support for Lenovo Thinkpad T420s ASoC: Add MediaTek MT6660 Speaker Amp Driver ASoC: dt-bindings: rt5645: add suppliers ASoC: max98090: fix deadlock in max98090_dapm_put_enum_double() ASoC: dapm: add snd_soc_dapm_put_enum_double_locked ...

We used to modify the headers so that they can be built without asoundlib.h and linux kernel headers, and the verbatim copy doesn't work as is. This patch removes again the linux/types.h inclusion and drop __user prefix that broke the build and adjusts the corresponding code.

|/ | | | | | | | | | | | | | | | | By taking into account the mapping from logical to DMA channels when enabling or disabling audio channels, ADAT channels 3 to 8 on the RME HDSPe AIO card are now correctly captured and played back in single speed mode. Since the mapping is an identity mapping for all cards except AIO and RayDAT, only those cards should be affected by this patch. It was tested on an AIO card. The patch needs testing on other cards, in particular RayDAT. Note: this patch does not solve ADAT capture and playback issues in double or triple speed mode. That seems to be another problem.
