[PATCH] ALSA: emu10k1: minor E-MU naming fixups
by Oswald Buddenhagen 08 May '23

08 May '23

- Fix mixer source port names. These will require some users to re-adjust their mixer settings, which seems acceptable: - The S/PDIF port is on the main 1010 card, not the 0202 daughter card - The 1616m CardBus card has all inputs on the dock, so there is no point in specifying it - Conversely, the 1010 card has "dispersed" inputs, so say where the ADAT port is, consistently with the S/PDIF port - The 1616m CardBus card is actually named E-MU 02 (due to the headphone output jack it has) - Fix capitalization of "E-MU" Signed-off-by: Oswald Buddenhagen <oswald.buddenhagen(a)gmx.de> --- sound/pci/emu10k1/emu10k1_main.c | 16 +++++++------- sound/pci/emu10k1/emumixer.c | 36 ++++++++++++++++---------------- 2 files changed, 26 insertions(+), 26 deletions(-) diff --git a/sound/pci/emu10k1/emu10k1_main.c b/sound/pci/emu10k1/emu10k1_main.c index 3abdaf1b9624..5d9d772e3a13 100644 --- a/sound/pci/emu10k1/emu10k1_main.c +++ b/sound/pci/emu10k1/emu10k1_main.c @@ -1310,7 +1310,7 @@ static const struct snd_emu_chip_details emu_chip_details[] = { /* Does NOT support sync daughter card (obviously). */ /* Tested by James(a)superbug.co.uk 4th Nov 2007. */ {.vendor = 0x1102, .device = 0x0008, .subsystem = 0x42011102, -

[PATCH v2] soundwire: bus: Don't filter slave alerts
by Charles Keepax 08 May '23

08 May '23

It makes sense to have only a single point responsible for ensuring that all currently pending IRQs are handled. The current code in sdw_handle_slave_alerts confusingly splits this process in two. This code will loop until the asserted IRQs are cleared but it will only handle IRQs that were already asserted when it was called. This means the caller must also loop (either manually, or through its IRQ mechanism) until the IRQs are all handled. It makes sense to either do all the looping in sdw_handle_slave_alerts or do no looping there and let the host controller repeatedly call it until things are handled. There are realistically two sensible host controllers, those that will generate an IRQ when the alert status changes and those that will generate an IRQ continuously whilst the alert status is high. The current code will work fine for the second of those systems but not the first with out additional looping in the host controller. Removing the code that filters out new IRQs whilst the handler is running enables both types of host controller to be supported and simplifies the code. The code will still only loop up to SDW_READ_INTR_CLEAR_RETRY times, so it shouldn't be possible for it to get completely stuck handling IRQs forever, and if you are generating IRQs faster than you can handle them you likely have bigger problems anyway. This fixes an issue on the Cadence SoundWire IP, which only generates IRQs on an alert status change, where an alert which arrives whilst another alert is being handled will never be handled and will block all future alerts from being handled.

[PATCH v3 0/7] ASoC: mediatek: mt8188: revise AFE driver
by Trevor Wu 05 May '23

05 May '23

The series of patches consists of three major changes. First, remove redundant supply for ADDA DAI dirver. Second, revise ETDM control including APLL dynamic switch via DAPM, so APLL can be enabled when it is really required. Finally, AFE probe function is updated. Bus protection change was dropped at the previous patch because the dependent change was not accepted.

How to mix multiple pcm capture stream into one and save to wav file as if it's from one single multi channel alsa card device
by semiydsemiyd＠163.com 04 May '23

Each capture device support 1 channel only: root@light-a-val:~# arecord -l **** List of CAPTURE Hardware Devices **** card 0: LightSoundCard [Light-Sound-Card], device 0: light-tdm-dai-slot1-ES7210 ADC 0 es7210.5-0042-1 [light-tdm-dai-slot1-ES7210 ADC 0 es7210.5-0042-1] Subdevices: 1/8 Subdevice #0: subdevice #0 card 0: LightSoundCard [Light-Sound-Card], device 1: light-tdm-dai-slot2-ES7210 ADC 0 es7210.5-0042-1 [light-tdm-dai-slot1-ES7210 ADC 0 es7210.5-0042-1] Subdevices: 2/8 Subdevice #1: subdevice #1 ... card 0: LightSoundCard [Light-Sound-Card], device 7: light-tdm-dai-slot8-ES7210 ADC 1 es7210.5-0042-1 [light-tdm-dai-slot1-ES7210 ADC 0 es7210.5-0042-1] Subdevices: 8/8 Subdevice #7: subdevice #7 the signal comes in TDM format from external codec ES7210 to my soc's TDM controller. each capture device has 1 channel that correspond to one of the slot in TDM. i have 8 TDM slots in configuration. so i have 8 devices in total. the reason that i have so many capture devices with 1 channel each is that, our tdm IC design decides that each tdm slot data_register would be assigned a dedicated dma channel. this is quite uncommon. thus i have 8 dma channels for 8 tdm slots. since i can only register one rx dma channel and one tx using devm_snd_dmaengine_pcm_register(). like: struct dmaengine_pcm { struct dma_chan *chan[SNDRV_PCM_STREAM_LAST + 1]; // there can be only one tx + one rx dma for struct dmaengine_pcm ... }; i have to register like 8 times to create 8 devices. the dts for the cpu dai driver for tdm slot1 would look like: tdm: audio_tdm@0xffcb000000 { #sound-dai-cells = <0>; ... dmas = <&dmac2 31>; dma-names = "rx"; ... }; now...i want to open all the devices at the same time. and have them save to one single wav file. As if i'm opening one single alsa capture device with 8 channels. the saved wav file should look something like this (take this 8 channel wav file for example) First Multichannel Sample -------------------------- {BB FF FF} 3 bytes slot1 {A1 FF FF} 3 bytes slot2 {00 00 00} 3 bytes slot3 {00 00 00} 3 bytes slot4 {00 00 00} 3 bytes slot5 {00 00 00} 3 bytes slot6 {00 00 00} 3 bytes slot7 {00 00 00} 3 bytes slot8 Second Multichannel Sample -------------------------- {E6 FF FF} 3 bytes slot1 .,.. etc .... Is this possible and if yes how can i do that? thank you guys semiyd

[PATCH 0/6] ASoC/soundwire: qcom: correctly probe devices after link init
by Krzysztof Kozlowski 03 May '23

03 May '23

Hi, Dependencies ============ 1. ASoC codec: changes are independent, however they should rather come the same cycle as Soundwire changes, to avoid new warning and small delay. 2. Soundwire: changes (context) depend on: https://lore.kernel.org/r/20230209131336.18252-3-srinivas.kandagatla@linaro… https://lore.kernel.org/all/20230418095447.577001-1-krzysztof.kozlowski@lin… Problems solved =============== Soundwire devices are supposed to be kept in reset state (powered off) till their probe() or component bind() callbacks. However if they are already powered on, then they might enumerate before the master initializes bus in qcom_swrm_init() leading to occasional errors like: qcom-soundwire 6d30000.soundwire-controller: Qualcomm Soundwire controller v2.0.0 Registered wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:4 (ops wcd938x_sdw_component_ops) wcd938x_codec audio-codec: bound sdw:0:0217:010d:00:3 (ops wcd938x_sdw_component_ops) qcom-soundwire 6ad0000.soundwire-controller: swrm_wait_for_wr_fifo_avail err write overflow The problem primarily lies in Qualcomm Soundwire controller probe() sequence: 1. request_threaded_irq() 2. sdw_bus_master_add() - which will cause probe() and component bind() of Soundwire devices, e.g. WCD938x codec drivers. Device drivers might already start accessing their registers. 3. qcom_swrm_init() - which initializes the link/bus and enables interrupts. Any access to device registers at (2) above, will fail because link/bus is not yet initialized.

Question regarding ALSA modules parameters
by Ivan Orlov 01 May '23

01 May '23

Hello! I have a question about the typical ALSA driver parameters, and maybe someone can answer me. Why it is necessary for ALSA module to have "index", "id" and "enable" parameters? They are mentioned as required in the "Writing an ALSA driver" and "Advanced Linux Sound Architecture - Driver Configuration guide" articles and used in many ALSA drivers, but for what purpose? Kind regards, Ivan Orlov.
