[PATCH v2 0/3] Add support for different DMIC configurations
by Mateusz Gorski 23 Apr '20

23 Apr '20

Set of patches to enable DMIC capture on different hardware configurations. Information about supported DMIC configuration is read from NHLT and correct pipeline configuration is selected automatically. Also, adding additional option for topology binary name which is based on used machine driver.

[PATCH] ALSA: hda: Always use jackpoll helper for jack update after resume
by Takashi Iwai 23 Apr '20

23 Apr '20

HD-audio codec driver applies a tricky procedure to forcibly perform the runtime resume by mimicking the usage count even if the device has been runtime-suspended beforehand. This was needed to assure to trigger the jack detection update after the system resume. And recently we also applied the similar logic to the HD-audio controller side. However this seems leading to some inconsistency, and eventually PCI controller gets screwed up. This patch is an attempt to fix and clean up those behavior: instead of the tricky runtime resume procedure, the existing jackpoll work is scheduled when such a forced codec resume is required. The jackpoll work will power up the codec, and this alone should suffice for the jack status update in usual cases. If the extra polling is requested (by checking codec->jackpoll_interval), the manual update is invoked after that, and the codec is powered down again. Also, we filter the spurious wake up of the codec from the controller runtime resume by checking codec->relaxed_resume flag. If this flag is set, basically we don't need to wake up explicitly, but it's supposed to be done via the audio component notifier.

[PATCH] ALSA: usb-audio: Fix usb audio refcnt leak when getting spdif
by Xiyu Yang 23 Apr '20

23 Apr '20

snd_microii_spdif_default_get() invokes snd_usb_lock_shutdown(), which increases the refcount of the snd_usb_audio object "chip". When snd_microii_spdif_default_get() returns, local variable "chip" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in several exception handling paths of snd_microii_spdif_default_get(). When those error scenarios occur such as usb_ifnum_to_if() returns NULL, the function forgets to decrease the refcnt increased by snd_usb_lock_shutdown(), causing a refcnt leak. Fix this issue by jumping to "end" label when those error scenarios occur.

[RFC PATCH 00/16] ASoC/SOF/clk/gpio/dt: add Hifiberry DAC+ PRO support
by Pierre-Louis Bossart 22 Apr '20

22 Apr '20

The Hifiberry DAC+ / DAC+ PRO is supported in the Raspberry PI tree but until now not in the mainline and not for ACPI platforms. This patchset implements the recommendations suggested by Mark Brown back in 2018: first add a gpiochip in the PCM512x codec driver, then use these gpios from a clock driver and the machine driver. Since this patchset relies on different subsystems, sending as RFC for now. I chose to import the original code from the Raspberry PI tree as is, and add my changes on top. If there is a preference to squash the changes that'd be fine. I also don't know if I should split this series in two, one for ASoC and one for clk changes? This patchset does not add changes to the sound/soc/bcm machine drivers, but that should be trivial once all the gpio/clock is available. Thanks to Andy Shevchenko for his help navigating the gpio subsystem and flagging mistakes in the use of lookup tables, and to Rob Herring for pointers on the DT bindings verification tools.

sound:core:oss: what determines the value of plugin->extra_data in rate_src_frames()?
by Xingyu Li 22 Apr '20

22 Apr '20

Hi all, I encountered a problem about ALSA subsystem when I try to reproduce a bug https://syzkaller.appspot.com/bug?id=54576f48248190caa29334a754275ce5e1d8be… . I run the PoC https://syzkaller.appspot.com/text?tag=ReproC&x=1275090ee00000, it is supposed to crash the kernel. But it sometimes does not. Then I found the point is rate_src_frames() in sound/core/oss/rate.c. When I can not reproduce the bug,data->old_src_frames variable in rate_src_frames() and the passed arguments frames are both 11. When it can reproduce, the value of data->old_src_frames is 85. The variable data is one member extra_data in plugin variable. But I can not find where it write to plugin->extra_data. So I want to what determines the value of plugin->extra_data? Why is the value of it different at different time? Thanks
