[alsa-devel] [PATCH] ALSA: msnd: Optimize / harden DSP and MIDI loops
by Takashi Iwai 06 Jul '17

06 Jul '17

The ISA msnd drivers have loops fetching the ring-buffer head, tail and size values inside the loops. Such codes are inefficient and fragile. This patch optimizes it, and also adds the sanity check to avoid the endless loops.

[alsa-devel] A problem about two microphones
by Hui Wang 06 Jul '17

06 Jul '17

Recently we met a problem, on a lenovo machine, it has two microphones(one is microphone, the other is headset-mic), and both of them are located in the front panel. When the driver assigns names for them (via the function hda_get_autocfg_input_label()), they are assigned the same name "Mic" since they have the same location. So there are two "Mic", but the pulseaudio can't handle two "Mic", in the pulseaudio, it can only handle multiple inputs/microphones with different names, like "Mic" and "Front Mic". If two microphones have the same name, we can only see one of them through pulseaudio. I don't know how to solve this problem, the simplest way to workaround it I can figure out is to change one of the microphone's location, let them have differnt location, then they have differnet names. Pin Default 0x02a19040: [Jack] Mic at Ext Front Changed to: Pin Default 0x04a19040: [Jack] Mic at Ext Right Do you have any ideas to solve this problem? The alsa-info.txt for this machine is at: http://paste.ubuntu.com/24967758/ Thanks, Hui.

[alsa-devel] [PATCH 0/3] mfd: move include files out of include/linux/i2c
by Wolfram Sang 06 Jul '17

06 Jul '17

It doesn't make sense to use include/linux/i2c for client drivers which may in fact rather be hwmon or input or whatever devices. As a result, I want to deprecate include/linux/i2c for good. This series moves the include files to a better location, for the mfd subsystem to include/linux/mfd. Because of twl.h, this touches quite some subsystems, but I still think it is worth it. I prefer the series to go upstream via the subsystem tree; if you prefer that I take it via I2C, just let me know. No runtime testing because of no HW, but buildbot is happy with this series at least. A branch can be found here: git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux.git i2c/platform_data Thanks and kind regards, Wolfram Wolfram Sang (3): mfd: dm355evm_msp: move header file out of I2C realm mfd: tps65010: move header file out of I2C realm mfd: twl: move header file out of I2C realm arch/arm/mach-omap1/board-h2-mmc.c | 2 +- arch/arm/mach-omap1/board-h2.c | 2 +- arch/arm/mach-omap1/board-h3-mmc.c | 2 +- arch/arm/mach-omap1/board-h3.c | 2 +- arch/arm/mach-omap1/board-osk.c | 2 +- arch/arm/mach-omap2/common.h | 2 +- arch/arm/mach-omap2/omap_twl.c | 2 +- arch/arm/mach-s3c24xx/mach-osiris-dvs.c | 2 +- arch/arm/mach-s3c24xx/mach-osiris.c | 2 +- drivers/gpio/gpio-twl4030.c | 2 +- drivers/iio/adc/twl4030-madc.c | 2 +- drivers/iio/adc/twl6030-gpadc.c | 2 +- drivers/input/keyboard/twl4030_keypad.c | 2 +- drivers/input/misc/dm355evm_keys.c | 2 +- drivers/input/misc/twl4030-pwrbutton.c | 2 +- drivers/input/misc/twl4030-vibra.c | 2 +- drivers/mfd/dm355evm_msp.c | 2 +- drivers/mfd/tps65010.c | 2 +- drivers/mfd/twl-core.c | 6 +++--- drivers/mfd/twl4030-audio.c | 2 +- drivers/mfd/twl4030-irq.c | 2 +- drivers/mfd/twl4030-power.c | 2 +- drivers/mfd/twl6030-irq.c | 2 +- drivers/phy/phy-twl4030-usb.c | 2 +- drivers/power/supply/twl4030_charger.c | 2 +- drivers/pwm/pwm-twl-led.c | 2 +- drivers/pwm/pwm-twl.c | 2 +- drivers/regulator/twl-regulator.c | 2 +- drivers/regulator/twl6030-regulator.c | 2 +- drivers/rtc/rtc-dm355evm.c | 2 +- drivers/rtc/rtc-twl.c | 2 +- drivers/usb/host/ohci-omap.c | 2 +- drivers/usb/phy/phy-isp1301-omap.c | 2 +- drivers/usb/phy/phy-twl6030-usb.c | 2 +- drivers/video/backlight/pandora_bl.c | 2 +- drivers/video/fbdev/omap/lcd_h3.c | 2 +- drivers/watchdog/twl4030_wdt.c | 2 +- include/linux/{i2c => mfd}/dm355evm_msp.h | 0 include/linux/{i2c => mfd}/tps65010.h | 2 +- include/linux/{i2c => mfd}/twl.h | 0 sound/soc/codecs/twl4030.c | 2 +- 41 files changed, 41 insertions(+), 41 deletions(-) rename include/linux/{i2c => mfd}/dm355evm_msp.h (100%) rename include/linux/{i2c => mfd}/tps65010.h (99%) rename include/linux/{i2c => mfd}/twl.h (100%) -- 2.11.0

[alsa-devel] [PATCH] ASoC: hdmi-codec: hdmi_codec_priv includes snd_kcontrol_new
by Kuninori Morimoto 06 Jul '17

06 Jul '17

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Current hdmi-codec driver is using hdmi_controls for "ELD" control. But, hdmi-codec driver might be used from many HDMIs. In such case, they will use same "ELD" name and kernel will indicate below error. xxx: control x:x:x:ELD:x is already present hdmi_controls will be registered in soc_probe_component(), and we can replace it by component driver probe function. This patch registers current hdmi_controls in new hdmi_probe(). If hdmi-codec is used from only 1 device, it will use "ELD" as control name (We can keep compatibility). If hdmi-codec is used from many devices, it will use "ELD.x" as control name.

[alsa-devel] [PATCH] ASoC: samsung: i2s: Supported high resolution rates
by Jaechul Lee 05 Jul '17

05 Jul '17

This driver can support more frequencies over 96KHz. There are no reasons to limit the frequency range below 96KHz. If codecs/amps or something else can't support high resolution rates, the constraints would be set rates properly because each drivers have its own limits.

[alsa-devel] ioctl(fd, SNDRV_CTL_IOCTL_ELEM_REPLACE, ... not working from userspace ?
by Fulup Ar Foll 04 Jul '17

04 Jul '17

Hi, I try to rename existing sound control from userspace. The goal is to create a generic abstraction layer for AutomotiveGradeLinux audio server While I found two hidden methods to access to low level functionalities from user space, non of them seems to accecp replace call. I isolated the code in two basic samples https://github.com/fulup-bzh/alsa-ctl-replace - First one uses a directt IOTCL model - Second one leverage private sndctl control handle. Any idea would be more than welcome. Fulup

[alsa-devel] [PATCH] ALSA: hda - Fix unbalance of i915 module refcount
by Takashi Iwai 04 Jul '17

04 Jul '17

The commit dba9b7b6ca1a ("ALSA: hda - Fix doubly initialization of i915 component") contained a typo that leads to the unbalance of i915 module reference. The value to be checked is not chip->driver_type but chip->driver_caps.
