That means not included at the hid_lenovo_leds list. In this case dev is still NULL and the function will return -ENODEV. The static array hid_lenovo_initial_leds is still set to store the current state of a LED type. This is used to set the LED appropriately if the tpx1cover is replugged. Maybe I should add a mutex to protect the hid_lenovo_leds list operations in hid-lenovo.c to fix the case if a unplug occurred concurrently to setting an led?! >> + >> + if (!dev) >> + return -ENODEV; >> + >> + if (!dev->brightness_set) >> + return -ENODEV; >> + >> + dev->brightness_set(dev, on ?

[alsa-devel] USB Driver Development Sinn 7 Status 24|96 (0x200c:0x1006)
by Marc Streckfuß 17 Dec '16

17 Dec '16

Hello Guys, I apologize in advance if this is the wrong mailing list (In general I am new to Mailing Lists), but I thought since I plan to develop a driver this might fit, I'm just not completely done. == Device Information The Device in Question is from the Brand "Sinn 7" with the name "Status 24|96", it's a relatively unknown recording interface design to be used in DAWs on Windows using Steinberg's Proprietary ASIO Interface. This is to provide a low-latency interface on Windows but it seems to be support a regular interface as well (at least you can use it as regular windows speaker and have different options there). It seems to be manufactured by Reloop, since that's the vendorId 0x200c. I tried the snd-usb-audio quirk for the Reloop Play already, but it didn't work (Applying the Quirk seemed to fail, due to endpoint mismatch, etc). >From reverse engineering the windows driver a bit I found the name " usb-audio.de". It's a website of the Pylotec GmbH which seems to provide the base boards for USB Audio Hardware used in many Interfaces (They have a page where they mention what is using their usb audio driver) The interesting lsusb output is this (I omitted the "empty" altsetting 0 for both interfaces, all classes are 0xFF == Vendor Specific): Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 1 bNumEndpoints 3 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 0 bInterfaceProtocol 0 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 5 Transfer Type Isochronous Synch Type Asynchronous Usage Type Data wMaxPacketSize 0x0004 1x 4 bytes bInterval 1 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x83 EP 3 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 1 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x05 EP 5 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 1 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 1 bAlternateSetting 1 bNumEndpoints 1 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 0 bInterfaceProtocol 0 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x86 EP 6 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 1 == My Findings So after days of trying out different quirks, building my own version of the snd-usb-audio and endless research I found out some stuff. A) I have captured the init sequence and I am able to redo it using libusb B) It turns out that there are 3 permanent communication types, even when I disable the device in Windows: There are writes to the Isochronous Endpoint 0x2 containing 32 Sub-Packets, so that is 128 Bytes of 0x0. Oddly enough that isn't the Audio data!! There are writes to the Bulk Endpoint 0x5 containing a variable size ranging roughly from ~16kB to 20kB. These are filled mostly with 0x0, but periodically (every 200h Bytes?) I had a 0xFD 0xFF Sequence. Those actually contain the Audio Data. I was able to produce some knocking sound when sending random values (either 0x0 or 0x1!) here. [I was expecting a white noise, though] => This is where I am stuck. I understand the idea of PCM in General, but I would expect it to send [0, 0xFF] values and not just 0x0 or 0x1, since that is a bandwidth waste. This and I would also expect a constant packet size. If it is variable, does that mean that the Sample Rate changes? (Note: I confirmed the 0x0..0x1 and the variable packet size both: By using libusb/pyUSB and by sniffing the traffic of a virtual windows box with Wireshark) There are reads from the Bulk Endpoint 0x86 (Note: Different InterfaceNumber, but it seems to work without changing the interface??) which result in an array of values ranging from 0x0 to 0x3. (Maybe that would apply to the output as well and during sniffing I just had the test sound too low gained?). Most of the time their size seems to be in line with the output bulk packets. Some of the sent sizes (data fields only) are: 19'986Bytes, 16'384 Bytes, 12'800 Bytes however most of the time it's 16k, whereas the output tends to go to 19k and the input to 12k (I have nothing attached to the input connectors). Now what I actually want to know: Does that protocol sound familiar to you? Do you have a clue on how to patch it in as a simple quirk? I was thinking maybe I can use a setup quirk and then let the FIXED_ENDPOINT do the rest? However I am stuck with the Format, I don't know whether that really is a known format or if I need some conversion and how it is with some synchronization clock and such. Basically I need information on how to proceed. - Marc Streckfuß

[alsa-devel] [alsa-lib][PATCH] ASoC: hdmi-codec: use unsigned type to structure members with bit-field instead of signed type
by Takashi Sakamoto 16 Dec '16

16 Dec '16

This is a fix for Linux 4.10-rc1. In C language specification, a bit-field is interpreted as a signed or unsigned integer type consisting of the specified number of bits. In GCC manual, the range of a signed bit field of N bits is from -(2^N) / 2 to ((2^N) / 2) - 1 https://www.gnu.org/software/gnu-c-manual/gnu-c-manual.html#Bit-Fields Therefore, when defined as 1 bit-field with signed type, variables can represents -1 and 0. The snd-soc-hdmi-codec module includes a structure which has signed type members with bit-fields. Codes of this module assign 0 and 1 to the members. This seems to result in implementation-dependent behaviours. As of v4.10-rc1 merge window, outside of sound subsystem, this structure is referred by below GPU modules. - tda998x - sti-drm - mediatek-drm-hdmi - msm As long as I review their codes relevant to the structure, the structure members are used just for condition statements and printk formats. My proposal of change is a bit intrusive to the printk formats but this may be acceptable. Totally, it's reasonable to use unsigned type for the structure members. This bug is detected by Sparse, static code analyzer with below warnings. ./include/sound/hdmi-codec.h:39:26: error: dubious one-bit signed bitfield ./include/sound/hdmi-codec.h:40:28: error: dubious one-bit signed bitfield ./include/sound/hdmi-codec.h:41:29: error: dubious one-bit signed bitfield ./include/sound/hdmi-codec.h:42:31: error: dubious one-bit signed bitfield CC: Jyri Sarha <jsarha(a)ti.com> CC: Jie Qiu <jie.qiu(a)mediatek.com> CC: Arnaud Pouliquen <arnaud.pouliquen(a)st.com> CC: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> CC: dri-devel(a)lists.freedesktop.org CC: stable(a)vger.kernel.org Fixes: 09184118a8ab ("ASoC: hdmi-codec: Add hdmi-codec for external HDMI-encoders") Signed-off-by: Takashi Sakamoto <o-takashi(a)sakamocchi.jp> --- include/sound/hdmi-codec.h | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/include/sound/hdmi-codec.h b/include/sound/hdmi-codec.h index 530c57b..915c435 100644 --- a/include/sound/hdmi-codec.h +++ b/include/sound/hdmi-codec.h @@ -36,10 +36,10 @@ struct hdmi_codec_daifmt { HDMI_AC97, HDMI_SPDIF, } fmt; - int bit_clk_inv:1; - int frame_clk_inv:1; - int bit_clk_master:1; - int frame_clk_master:1; + unsigned int bit_clk_inv:1; + unsigned int frame_clk_inv:1; + unsigned int bit_clk_master:1; + unsigned int frame_clk_master:1; }; /* -- 2.9.3

[alsa-devel] [PATCH] ASoC: da7218: Set DAI output pin high impedance when not in use
by Adam Thomson 16 Dec '16

16 Dec '16

For TDM mode, the I2S data out line can be shared between mutliple codecs. In this scenario, only the active codec should be using the line, and all others should be high impedance. However, currently in the driver this configuration isn't set when capture is inactive, and the line remains driven. This patch updates the AIF_OUT widget to set the DAI output pin of the device as high impedance when not in use.

[alsa-devel] [PATCH v2] ASoC: Intel: bytcr_rt5640: fallback mechanism if MCLK is not enabled
by Pierre-Louis Bossart 16 Dec '16

16 Dec '16

Commit df1a2776a795 ("ASoC: Intel: bytcr_rt5640: add MCLK support") was merged but the corresponding clock framework patches have not, after being bumped from audio to clock to x86 domains. The missing clock-related patches result in a regression starting with 4.9 with the audio card not being created. Rather than reverting this commit and all following updates already queued up for 4.10, handle run-time dependency on MCLK and fall back to the previous bit-clock mode. This provides the same functionality as in 4.8 for Baytrail devices. On Baytrail-CR most devices remain silent with this fallback but additional patches are needed anyway. As suggested by Mark Brown, the fallback is only allowed with -ENOENT, all other run-time errors, including -EPROBE_DEFER, will stop the probe with no sound card registered.

Hello Kuninori Morimoto, The patch d1f83d6ef43b: "ASoC: rsnd: call missing snd_ctl_remove()" from Feb 2, 2015, leads to the following static checker warning: sound/soc/sh/rcar/core.c:1034 __rsnd_kctrl_new() error: double free of 'kctrl' sound/soc/sh/rcar/core.c 1026 int ret; 1027 1028 kctrl = snd_ctl_new1(&knew, mod); 1029 if (!kctrl) 1030 return -ENOMEM; 1031 1032 ret = snd_ctl_add(card, kctrl); 1033 if (ret < 0) { 1034 snd_ctl_free_one(kctrl); The snd_ctl_add() function frees kctrl on error. It's a confusing layering violation IMHO but there are a lot of callers so I'm too lazy to clean this up myself... 1035 return ret; 1036 } 1037 regards, dan carpenter

[alsa-devel] [PATCH 0/5] ASoC/arizona: Ensure pin searches use widget name prefix
by Richard Fitzgerald 15 Dec '16

15 Dec '16

The name of a codec pin can have an optional prefix string, which is defined by the audio machine driver. The snd_soc_dapm_x_pin functions take the fully-specified name including the prefix and so the existing code would fail to find the pin if the audio machine driver had added a prefix. This patch chain adds new helper functions that take a non-prefixed name for a specific ASoC component and internally add that component's prefix. The other patches update the arizona drivers to use these new functions.

[alsa-devel] [PATCH] ASoC: samsung: Remove tests of member address
by Krzysztof Kozlowski 15 Dec '16

15 Dec '16

The driver was checking for non-NULL address of struct's members: - s3c_audio_pdata->type (union), - s3c_audio_pdata->type.i2s (embedded struct). This is pointless as these will be always non-NULL. The 's3c_audio_pdata' is always initialized in static memory so it will be zeroed. Additionally the 'type' member was an union with only one member. It is safe to reorganize the structures to get rid of useless union and checks for addresses to fix the coccinelle warning: >> sound/soc/samsung/i2s.c:1270:2-4: ERROR: test of a variable/field address Reported-by: kbuild test robot <fengguang.wu(a)intel.com> Signed-off-by: Krzysztof Kozlowski <krzk(a)kernel.org> --- Not tested on the hardware. --- arch/arm/mach-s3c64xx/dev-audio.c | 4 +--- include/linux/platform_data/asoc-s3c.h | 6 ++---- sound/soc/samsung/i2s.c | 10 ++-------- 3 files changed, 5 insertions(+), 15 deletions(-) diff --git a/arch/arm/mach-s3c64xx/dev-audio.c b/arch/arm/mach-s3c64xx/dev-audio.c index b57783371d52..247dcc0b691e 100644 --- a/arch/arm/mach-s3c64xx/dev-audio.c +++ b/arch/arm/mach-s3c64xx/dev-audio.c @@ -106,9 +106,7 @@ static struct s3c_audio_pdata i2sv4_pdata = { .dma_playback = DMACH_HSI_I2SV40_TX, .dma_capture = DMACH_HSI_I2SV40_RX, .type = { - .i2s = { - .quirks = QUIRK_PRI_6CHAN, - }, + .quirks = QUIRK_PRI_6CHAN, }, }; diff --git a/include/linux/platform_data/asoc-s3c.h b/include/linux/platform_data/asoc-s3c.h index 15bf56ee8af7..90641a5daaf0 100644 --- a/include/linux/platform_data/asoc-s3c.h +++ b/include/linux/platform_data/asoc-s3c.h @@ -18,7 +18,7 @@ extern void s3c64xx_ac97_setup_gpio(int); -struct samsung_i2s { +struct samsung_i2s_type { /* If the Primary DAI has 5.1 Channels */ #define QUIRK_PRI_6CHAN (1 << 0) /* If the I2S block has a Stereo Overlay Channel */ @@ -47,7 +47,5 @@ struct s3c_audio_pdata { void *dma_capture; void *dma_play_sec; void *dma_capture_mic; - union { - struct samsung_i2s i2s; - } type; + struct samsung_i2s_type type; }; diff --git a/sound/soc/samsung/i2s.c b/sound/soc/samsung/i2s.c index e00974bc5616..d55326289a4a 100644 --- a/sound/soc/samsung/i2s.c +++ b/sound/soc/samsung/i2s.c @@ -1218,7 +1218,6 @@ static int samsung_i2s_probe(struct platform_device *pdev) { struct i2s_dai *pri_dai, *sec_dai = NULL; struct s3c_audio_pdata *i2s_pdata = pdev->dev.platform_data; - struct samsung_i2s *i2s_cfg = NULL; struct resource *res; u32 regs_base, quirks = 0, idma_addr = 0; struct device_node *np = pdev->dev.of_node; @@ -1267,13 +1266,8 @@ static int samsung_i2s_probe(struct platform_device *pdev) pri_dai->dma_capture.filter_data = i2s_pdata->dma_capture; pri_dai->filter = i2s_pdata->dma_filter; - if (&i2s_pdata->type) - i2s_cfg = &i2s_pdata->type.i2s; - - if (i2s_cfg) { - quirks = i2s_cfg->quirks; - idma_addr = i2s_cfg->idma_addr; - } + quirks = i2s_pdata->type.quirks; + idma_addr = i2s_pdata->type.idma_addr; } else { quirks = i2s_dai_data->quirks; if (of_property_read_u32(np, "samsung,idma-addr", -- 2.7.4

[alsa-devel] [PATCH 0/2] register atmel-ssc as sound DAI w/o platform driver
by Peter Rosin 15 Dec '16

15 Dec '16

Hi! The Atmel SSC is currently not usable as an audio DAI unless someone registers it with ASoC. This is currently delegated to a platform driver for every possible audio use, and prevents the SSC from being used as a cpu DAI with the simple-audio-card driver. The first patch fixes this. The second patch simplifies one of these platform drivers, since it can now rely on the SSC to register itself with ASoC. However, this may not be a possible simplification for other, older, drivers since it also requires device tree changes.

[alsa-devel] [PATCH v2 0/2] register atmel-ssc as sound DAI w/o platform driver
by Peter Rosin 15 Dec '16

15 Dec '16

Hi! v1 -> v2 changes - add ack from Rob Herring on patch 1/2. - add reasons why breaking compatibility is ok for patch 2/2 (requested by Rob). - add #sound-dai-cells to the ssc0 node in the devcietree example. The Atmel SSC is currently not usable as an audio DAI unless someone registers it with ASoC.

[alsa-devel] [PATCH v2 00/13] ASoC: Intel: Skylake: Driver updates
by jeeja.kp＠intel.com 15 Dec '16

15 Dec '16

From: Jeeja KP <jeeja.kp(a)intel.com> This patch series includes driver updates for the handling scenarios during System S0/S3 transitions when audio stream is stopped during system. o move DMA configuration in DSP Gateway Module widget event handler to ensure DMA is configured after resume. o Enable SSP MLCK using Supply widget. This will ensure the MCLK is enabled when the widget is power on. o Check DMA decouple register state before coupling/decoupling the DMA. o In case of HDMI pass-through pipe, reset only the FE Pipe when stream in in XRUN state. o Resume the stream from HW renderer position. o HDMI Codec pin and converter state need to be restored when stream is resumed. Changes in v2: - Addressed Mark's comment on patch 1, split this into 2 as this had additional changes other than configuring the DMA. - Addressed Takashi's comment on the usage of snd_hdac_updatel() Jeeja KP (13): ASoC: Intel: Skylake: Update link_index and format in pipe params ASoC: Intel: Skylake: Add helper function to setup host/link dma ASoC: Intel: Skylake: Configure DMA in PRE_PMD handler of Mixer ASoC: Intel: Skylake: Removed unused skl_get_format() ALSA: hda: check stream decoupled register state ASoC: Intel: Skylake: Add set_tristate DAI ops to enable SSP MCLK ASoC: Intel: Skylake: Remove unused SSP BE prepare DAI ops ASoC: Intel: Skylake: Add supply widget as non DSP widget ASoC: Intel: Skylake: Add supply widget in skl_nau_max machine ASoC: Intel: Skylake: Add supply widget in bxt_da_max machine ASoC: Intel: Skylake: Don't reset pass-through pipe in BE prepare ASoC: Intel: Skylake: set the resume point to LPIB ASoC: hdac_hdmi: Enable pin and converter in prepare sound/hda/ext/hdac_ext_stream.c | 15 +- sound/soc/codecs/hdac_hdmi.c | 28 ++-- sound/soc/intel/boards/bxt_da7219_max98357a.c | 34 ++++ sound/soc/intel/boards/skl_nau88l25_max98357a.c | 34 ++++ sound/soc/intel/skylake/skl-pcm.c | 210 +++++++++++++----------- sound/soc/intel/skylake/skl-topology.c | 27 ++- sound/soc/intel/skylake/skl-topology.h | 6 + 7 files changed, 240 insertions(+), 114 deletions(-) -- 2.5.0

[alsa-devel] [PATCH] ASoC: Intel: bytcr_rt5640: fallback mechanism if MCLK is not enabled
by Pierre-Louis Bossart 15 Dec '16

15 Dec '16

Commit df1a2776a795 ("ASoC: Intel: bytcr_rt5640: add MCLK support") was merged but the corresponding clock framework patches have not, after being bumped from audio to clock to x86 domains. The missing clock-related patches result in a regression starting with 4.9 with the audio card not being created. Rather than reverting this commit and all following updates already queued up for 4.10, handle run-time dependency on MCLK and fall back to the previous bit-clock mode. This provides the same functionality as in 4.8 for Baytrail devices. On Baytrail-CR most devices remain silent with this fallback but additional patches are needed anyway. This patch should be applied to -stable as well as ASoC 4.10 fixes Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> --- sound/soc/intel/boards/bytcr_rt5640.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/sound/soc/intel/boards/bytcr_rt5640.c b/sound/soc/intel/boards/bytcr_rt5640.c index 507a86a..4a8b509 100644 --- a/sound/soc/intel/boards/bytcr_rt5640.c +++ b/sound/soc/intel/boards/bytcr_rt5640.c @@ -828,7 +828,9 @@ static int snd_byt_rt5640_mc_probe(struct platform_device *pdev) dev_err(&pdev->dev, "Failed to get MCLK from pmc_plt_clk_3: %ld\n", PTR_ERR(priv->mclk)); - return PTR_ERR(priv->mclk); + + /* Fall back to bitclock only */ + byt_rt5640_quirk &= ~BYT_RT5640_MCLK_EN; } } -- 2.9.3

[alsa-devel] [PATCH] ASoC: dwc: Fix PIO mode initialization
by Jose Abreu 14 Dec '16

14 Dec '16

We can no longer rely on the return value of devm_snd_dmaengine_pcm_register(...) to check if the DMA handle is declared in the DT. Previously this check activated PIO mode but currently dma_request_chan returns either a valid channel or -EPROBE_DEFER. In order to activate PIO mode check instead if the interrupt line is declared. This reflects better what is documented in the DT bindings (see Documentation/devicetree/bindings/sound/ designware-i2s.txt). Also, initialize use_pio variable which was never being set causing PIO mode to never work.

[alsa-devel] [PATCH] alsa-lib: update linked hw_ptr and appl_ptr
by sutar.mounesh＠gmail.com 14 Dec '16

14 Dec '16

From: Andreas Pape <apape(a)de.adit-jv.com> Plugin file provides no private hw_ptr and appl_ptr but instead links them to the slave pcm. If the slave pcm itself changes its hw_ptr or app_prt this needs to be done in file plugin, too. Plugin 'plug' is such a candidate changing the hw_ptr and app_ptr in hw_params call dependent on the automatically inserted plugins. ALSA unfortunately has no support for automatically updating chained pointers. A notification on pointer change seems to be prepared inside the snd_pcm_set_ptr() routine via rbptr->changed(), but it is not (yet) implemented so that we need to care for it manually.

[alsa-devel] [alsa-lib][PATCH] pcm: fix wrong document references to PCM APIs which perform direct memory access with frame copying
by Takashi Sakamoto 13 Dec '16

13 Dec '16

In a design of ALSA PCM interface, for PCM frame transmission to/from kernel space, applications can select from two options; direct memory access or ioctl(2). Available options are decided depending on device capacity and machine architecture. Applications can get available options by the first entry of 'struct snd_pcm_hw_params.masks'. When the mask includes 'SNDRV_PCM_ACCESS_MMAP_xxx', applications can use direct memory access. For this use case, userspace library has two types of PCM API. One is to expose a pointer over the memory to start reading/writing PCM frames. Another is to copy PCM frames between the memory and a given buffer. Current documentation includes wrong references to these APIs to describe their advantages/disadvantages. This confuses application developers because the references indicate PCM APIs to execute ioctl(2) operation to read/write PCM frames. This commit fixes the bug.

[alsa-devel] [PATCH] hiface: Fix sample rate changes
by Jussi Laako 12 Dec '16

12 Dec '16

When attempting to change sample rate for the interface after first set-play cycle, the change is not reflected to the hardware, while from user space everything seems to go fine. This patch fixes the issue and the driver now behaves the same way as for example the USB Audio Class driver.

[alsa-devel] [PATCH] ALSA: usb-audio: Eliminate noise at the start of DSD playback.
by Nobutaka Okabe 12 Dec '16

12 Dec '16

[Problem] In some USB DACs, a terrible pop noise comes to be heard at the start of DSD playback (in the following situations). - play first DSD track - change from PCM track to DSD track - change from DSD64 track to DSD128 track (and etc...) - seek DSD track - Fast-Forward/Rewind DSD track [Cause] At the start of playback, there is a little silence. The silence bit pattern "0x69" is required on DSD mode, but it is not like that. [Solution] This patch adds DSD silence pattern to the endpoint settings.

This patch adds native DSD support for the following devices. - TEAC NT-503 - TEAC UD-503 - TEAC UD-501 (1)Add quirks for native DSD support for TEAC devices. (2)A specific vendor command is needed to switch between PCM/DOP and DSD mode, same as Denon/Marantz devices.

[alsa-devel] [PATCH] ASoC: topology: avoid uninitialized kcontrol_type
by Arnd Bergmann 12 Dec '16

12 Dec '16

When num_kcontrols is zero, widget->dobj.widget.kcontrol_type gets set to an uninitialized local variable: sound/soc/soc-topology.c: In function 'soc_tplg_dapm_widget_create': sound/soc/soc-topology.c:1566:36: error: 'kcontrol_type' may be used uninitialized in this function [-Werror=maybe-uninitialized] I could not figure out which of the valid types would be appropriate here, so this sets it to '0', which is invalid but at least well-defined here. There is probably a better way to address the issue.

add Anthony Wong @ Canonical. I'm about to go on break and won't have access to hardware for a while. Anthony, Your team has this hardware more readily available than I do. Would you be able to have someone on the team verify this series?
