Query about xrun on usb/pcm
by Carl Hetherington 06 Dec '22

06 Dec '22

Hi all, I wonder if anybody has any clues/suggestions about problem I'm seeing with an XMOS-based USB sound card. As far as I can see, the card has endpoint 0x82 set up for capture data, 0x2 for playback data, and 0x82 is also used as the sync endpoint for playback. I'm assuming that's a fairly common arrangement? I am testing it using simultaneous playback and capture, and simulating a high-CPU-load case by sleeping for long enough to cause a lot of xruns. After some random time, I see a failure case that I'm struggling to explain. It goes like this: There's an XRUN on the playback PCM, so __snd_pcm_xrun happens, then stop_endpoints() happens, and: it decides not to stop 0x82 because its running is > 1 it stops 0x2, so its state goes to EP_STATE_STOPPING Then the ALSA userspace code calls prepare on the playback PCM to get it going again. This ends up in wait_clear_urbs(), which does nothing with 0x82 as it is still running. At this point, the prepare thread is interrupted by an XRUN on the capture PCM. With this PCM, there is no sync endpoint, and 0x82 is the data endpoint. In the xrun handler: stop_urbs() sets 0x82 to EP_STATE_STOPPING. ... and the xrun handler finishes. Then we end up back in the prepare for the playback PCM. wait_clear_urbs() then sets 0x2 to STOPPED, and the prepare is finished. Now, snd_usb_endpoint_start() is called on 0x2 and that is fine. Next, snd_usb_endpoint_start() is called on 0x82 and that fails because its state is still STOPPING. At this point things seem broken. Does anyone have a hint about where in this sequence things are going wrong, and maybe even why? I'm more than happy to clarify anything I can, or provide more debugging information. Thanks in advance! Best, Carl

[PATCH v2 00/16] ASoC: Intel: avs: Data probing and fw logging
by Cezary Rojewski 05 Dec '22

05 Dec '22

The patchset focuses on debug functionality for the avs-driver. Two major blocks are covered here: data probing and AudioDSP firmware logging. Both are configured and controlled through debugfs. Data probing is a AudioDSP debug functionality which allows for gathering the actual data that is being routed to or from a module. Helps in debugging its processing capabilities - navigate to a specific module which may have caused a glitch within a pipeline (set of modules bound together). First few allow for assigning compress stream to a HDAudio stream, what is currently limited to pcm substreams only. These patches were already present on this list and reviewed in the past [1]. The next few tidy existing debug-related code up so it's ready for addition of new functionalities and make it clear which part of the avs is debug related and which is not. These also simplify the existing locking around the trace fifo. Afterward, debug-related IPCs are defined along with stub soc-component and compress DAI operations. Not much is done there as it's not a standard PCM streaming scenario. Most code found in compress operations is inherited from the HOST side of HDAudio streaming found in pcm.c file of the driver. Finally, a debugfs file operations are defined. These facilitate connecting to DSP modules from which the data shall be gathered as well as control and configuration of firmware logging. Additionally, entries are added to allow for dumping snapshots of key memory windows. Changes in v2: - reordered sign offs in patch 03 as reported by Takashi - fixed issue reported by ikp - unintilialized 'runtime' variable in patch 03 - added missing module_get_upon_open in component driver declaration [1]: https://lore.kernel.org/alsa-devel/20200124190413.18154-1-cezary.rojewski@i… Cezary Rojewski (16): ALSA: hda: Allow for compress stream to hdac_ext_stream assignment ALSA: hda: Prepare for compress stream support ALSA: hda: Interrupt servicing and BDL setup for compress streams ASoC: Intel: avs: Introduce avs_log_buffer_status_locked() ASoC: Intel: avs: Drop fifo_lock ASoC: Intel: avs: Introduce debug-context aware helpers ASoC: Intel: avs: Make enable_logs() dependent on DEBUG_FS ASoC: Intel: avs: Drop usage of debug members in non-debug code ASoC: Intel: avs: Add data probing requests ASoC: Intel: avs: Probe compress operations ASoC: Intel: avs: Data probing soc-component ASoC: Intel: avs: Add probe machine board ASoC: Intel: avs: Probing and firmware tracing over debugfs ASoC: Intel: avs: Gather remaining logs on strace_release() ASoC: Intel: avs: Allow for dumping FW_REGS area ASoC: Intel: avs: Allow for dumping debug window snapshot include/sound/hdaudio_ext.h | 2 + sound/hda/ext/hdac_ext_stream.c | 41 +++ sound/hda/hdac_controller.c | 4 +- sound/hda/hdac_stream.c | 51 +-- sound/soc/intel/Kconfig | 1 + sound/soc/intel/avs/Makefile | 4 + sound/soc/intel/avs/apl.c | 24 +- sound/soc/intel/avs/avs.h | 80 ++++- sound/soc/intel/avs/board_selection.c | 33 ++ sound/soc/intel/avs/boards/Kconfig | 8 + sound/soc/intel/avs/boards/Makefile | 2 + sound/soc/intel/avs/boards/probe.c | 64 ++++ sound/soc/intel/avs/core.c | 2 + sound/soc/intel/avs/debugfs.c | 436 ++++++++++++++++++++++++++ sound/soc/intel/avs/ipc.c | 2 +- sound/soc/intel/avs/messages.c | 104 +++++- sound/soc/intel/avs/messages.h | 53 ++++ sound/soc/intel/avs/pcm.c | 6 +- sound/soc/intel/avs/probes.c | 313 ++++++++++++++++++ sound/soc/intel/avs/registers.h | 3 +- sound/soc/intel/avs/skl.c | 17 +- sound/soc/intel/avs/utils.c | 22 -- 22 files changed, 1172 insertions(+), 100 deletions(-) create mode 100644 sound/soc/intel/avs/boards/probe.c create mode 100644 sound/soc/intel/avs/debugfs.c create mode 100644 sound/soc/intel/avs/probes.c -- 2.25.1

[PATCH] ASoC: sof_es8336: fix possible use-after-free in sof_es8336_remove()
by Yang Yingliang 05 Dec '22

05 Dec '22

sof_es8336_remove() calls cancel_delayed_work(). However, that function does not wait until the work function finishes. This means that the callback function may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling cancel_delayed_work_sync(), which ensures that the work is properly cancelled, no longer running, and unable to re-schedule itself.
