[PATCH] Pioneer devices: engage implicit feedback sync for playback
by Geraldo 05 Apr '21

05 Apr '21

Hello everybody, This is a highly experimental patch on top of 5.12-rc4 that's supposed to engage implicit feedback sync on the playback for Pioneer devices. Without implicit feedback sync the inputs started glitching due to clock drift in about an hour in my Pioneer DJ DDJ-SR2. If you own a Pioneer device please test this patch and verify in the dyndbg logs if your capture(input) EP is being opened twice and if implicit_fb = 1 for the playback EP. I can't ask of you all to test this for hours and hours but if you wanted to have an excuse to digitize vinyl or spin up DVS this is your perfect one. Help open source! I'd like to thank Takashi Iwai for his tireless support in the Pioneer regression and beyond. Hopefully this highly experimental feature's code can be polished and mainlined eventually. --- implicit.c.git 2021-03-21 22:40:48.363417245 -0300 +++ implicit.c 2021-03-22 01:03:05.726729481 -0300 @@ -177,30 +177,31 @@ ifnum, alts); } -/* Playback and capture EPs on Pioneer devices share the same iface/altset, - * but they don't seem working with the implicit fb mode well, hence we - * just return as if the sync were already set up. +/* Pioneer devices: playback and capture streams sharing the same iface/altset */ -static int skip_pioneer_sync_ep(struct snd_usb_audio *chip, - struct audioformat *fmt, - struct usb_host_interface *alts) -{ - struct usb_endpoint_descriptor *epd; - - if (alts->desc.bNumEndpoints != 2) - return 0; - - epd = get_endpoint(alts, 1); - if (!usb_endpoint_is_isoc_in(epd) || - (epd->bmAttributes & USB_ENDPOINT_SYNCTYPE) != USB_ENDPOINT_SYNC_ASYNC || - ((epd->bmAttributes & USB_ENDPOINT_USAGE_MASK) != - USB_ENDPOINT_USAGE_DATA && - (epd->bmAttributes & USB_ENDPOINT_USAGE_MASK) != - USB_ENDPOINT_USAGE_IMPLICIT_FB)) - return 0; - return 1; /* don't handle with the implicit fb, just skip sync EP */ +static int add_pioneer_implicit_fb(struct snd_usb_audio *chip, + struct audioformat *fmt, + struct usb_host_interface *alts) +{ + struct usb_endpoint_descriptor *epd; + + if (alts->desc.bNumEndpoints != 2) + return 0; + + epd = get_endpoint(alts, 1); + + if (!usb_endpoint_is_isoc_in(epd) || + (epd->bmAttributes & USB_ENDPOINT_SYNCTYPE) != USB_ENDPOINT_SYNC_ASYNC || + ((epd->bmAttributes & USB_ENDPOINT_USAGE_MASK) != + USB_ENDPOINT_USAGE_DATA && + (epd->bmAttributes & USB_ENDPOINT_USAGE_MASK) != + USB_ENDPOINT_USAGE_IMPLICIT_FB)) + return 0; + return add_implicit_fb_sync_ep(chip, fmt, epd->bEndpointAddress, 1, + alts->desc.bInterfaceNumber, alts); } + static int __add_generic_implicit_fb(struct snd_usb_audio *chip, struct audioformat *fmt, int iface, int altset) @@ -306,7 +307,7 @@ alts->desc.bInterfaceClass == USB_CLASS_VENDOR_SPEC && (USB_ID_VENDOR(chip->usb_id) == 0x2b73 || /* Pioneer */ USB_ID_VENDOR(chip->usb_id) == 0x08e4 /* Pioneer */)) { - if (skip_pioneer_sync_ep(chip, fmt, alts)) + if (add_pioneer_implicit_fb(chip, fmt, alts)) return 1; } @@ -339,8 +340,20 @@ struct audioformat *fmt, struct usb_host_interface *alts) { - if (fmt->endpoint & USB_DIR_IN) - return audioformat_capture_quirk(chip, fmt, alts); + bool isPioneer; + + if (alts->desc.bInterfaceClass == USB_CLASS_VENDOR_SPEC && + (USB_ID_VENDOR(chip->usb_id) == 0x2b73 || /* Pioneer */ + USB_ID_VENDOR(chip->usb_id) == 0x08e4 /* Pioneer */)) + isPioneer = true; + + if (fmt->endpoint & USB_DIR_IN) { + if (isPioneer == true) + return 1; + else + return audioformat_capture_quirk(chip, fmt, alts); + } + else return audioformat_implicit_fb_quirk(chip, fmt, alts); } --- endpoint.c.git 2021-03-21 22:40:54.800084101 -0300 +++ endpoint.c 2021-03-21 22:45:41.543425855 -0300 @@ -688,7 +688,7 @@ goto unlock; } - if (!ep->opened) { + if (ep->opened < 2) { if (is_sync_ep) { ep->iface = fp->sync_iface; ep->altsetting = fp->sync_altsetting;

ALC1220 and presence of ucm2/ucm.conf breaks audio
by GitHub issues - opened 04 Apr '21

04 Apr '21

alsa-project/alsa-ucm-conf issue #86 was opened from devnull0000: I'd want to make a better report but I am not an ALSA expert, so the issue is that after update I lose any sound and I use ALC1220 codec on MSI MEG X570 GODLIKE motherboard. Deep googling gave me the report: https://bugs.archlinux.org/task/67058 So indeed deletion of the file helped immediately. The bug is super confusing because it looks like the device is present at alsa level but absent on Pulse Audio and it is not shown in GUI at all. I am at alsa-ucm-conf-1.2.4, linux-5.11.11, pulseaudio 13.0, gentoo. Issue URL : https://github.com/alsa-project/alsa-ucm-conf/issues/86 Repository URL: https://github.com/alsa-project/alsa-ucm-conf

[PATCH v6 0/2] hardware-privacy-implementation-for-dell-laptop
by Perry Yuan 04 Apr '21

04 Apr '21

From: Perry Yuan <perry_yuan(a)dell.com> Hi All, This patch set is a new driver for Dell mobile platform that has the hardware privacy feature including micmute,camera mute. For micmute led control, the hotkey is Fn + F4, it is a hardware based mute state, and new privacy will prevent micphone void input from hardware layer, any application cannot get voice data when micmute activated. Camera mute use a new hardware design to control the camrea shutter. When video is muted, no OS application should be functionally able to capture images of the person/environment in front of the system Older history: [1]https://patchwork.kernel.org/project/platform-driver-x86/patch/2020122813… [2]https://patchwork.kernel.org/project/alsa-devel/patch/20201103125859.8759… [3]https://www.spinics.net/lists/alsa-devel/msg120537.html [4]https://github.com/thesofproject/linux/pull/2660 [5]https://github.com/thesofproject/linux/issues/2496 Perry Yuan (2): platform/x86: dell-privacy: Add support for Dell hardware privacy ASoC: rt715:add micmute led state control supports .../testing/sysfs-platform-dell-privacy-wmi | 55 +++ drivers/platform/x86/dell/Kconfig | 14 + drivers/platform/x86/dell/Makefile | 1 + drivers/platform/x86/dell/dell-laptop.c | 23 +- drivers/platform/x86/dell/dell-privacy-wmi.c | 441 ++++++++++++++++++ drivers/platform/x86/dell/dell-privacy-wmi.h | 32 ++ drivers/platform/x86/dell/dell-wmi.c | 13 +- sound/soc/codecs/rt715-sdca.c | 41 +- sound/soc/codecs/rt715.c | 41 ++ 9 files changed, 653 insertions(+), 8 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-platform-dell-privacy-wmi create mode 100644 drivers/platform/x86/dell/dell-privacy-wmi.c create mode 100644 drivers/platform/x86/dell/dell-privacy-wmi.h -- 2.25.1

by Hans de Goede 02 Apr '21

Hi All, Here is a patch series to enable sound on the Dell Venue 10 Pro 5055 tablet this series also includes 2 generic improvements to rt5672 support: 1. Add support for boards using Bay Trail CR (SSP0) in combination with a rt5672 codec 2. Set the card's components string based on the DMI info, so that we don't need to duplicate the DMI quirks in userspace (in the UCM profile) I've a patch to add support for the components string to the UCM profile for these boards available here: https://github.com/jwrdegoede/alsa-ucm-conf/commit/fedacc2bdc530b6febac665d… I will submit this upstream once the kernel side has landed.

[PATCH] ASoC: fsl_esai: Fix TDM slot setup for I2S mode
by Alexander Shiyan 02 Apr '21

02 Apr '21

When using the driver in I2S TDM mode, the fsl_esai_startup() function rewrites the number of slots previously set by the fsl_esai_set_dai_tdm_slot() function to 2. To fix this, let's use the saved slot count value or, if TDM is not used and the number of slots is not set, the driver will use the default value (2), which is set by fsl_esai_probe().
