alsa-project/alsa-ucm-conf pull request #143 was opened from lordhoto: This patch depends on Linux 5.17. This board features an Realtek ALC4080 chip. The various inputs and outputs are distributed over multiple hardware devices: * Input - hw:$card,0 loop back from speaker (called "Analog In") - hw:$card,1 line in at back panel - hw:$card,2 microphone from front AND back panel * Output - hw:$card,0 speaker output at back panel (up to 7.1) - hw:$card,1 headerphone output at front panel - hw:$card,2 could not figure this one out - hw:$card,3 guessed S/PDIF output (sadly no way to test) By default Mic and Line in are disabled. This confuses applications, thus I made the profile enable them by default. Without an UCM profile PulseAudio is not able to create output on the front panel nor record any microphone input.

[RFC PATCH v2 0/6] Flexible codec clock configuration
by Sameer Pujar 29 Mar '22

29 Mar '22

Typically the codec drivers require setting up of Sysclk. Sometimes presence of internal PLL can provide more options of Sysclk configuration. Presently ASoC provides callbacks set_sysclk() and set_pll() in such cases. However it comes with following limitations considering generic machine drivers (simple-card or audio-graph-card): 1. The Sysclk source needs to be passed to set_sysclk() callback. Presently simple-card or audio-graph-card card rely on default source value (which is 0). If any other source needs to be used, it is currently not possible. 2. The same would be true for codec PLL configuration as well, though simple-card or audio-graph-card don't have support yet for the PLL configuration. Earlier attempt[0] to address above was not felt suitable. The suggestion was to use standard clock based bindings instead. This RFC series takes RT5659 as a reference and exposes clock relationships via DT. **This is not in the final shape yet**, but I wanted to get some valuable feedback to understand if the idea is right. If this appears fine, this can be extended to other codecs (wherever necessary). This does not completely remove the need of set_sysclk() callback because the clock requirement (MCLK * fs) would come from the machine driver. But machine driver need not worry about Sysclk source. It would be internally managed by Codec via DT clock relationships.

[PATCH] mediatek: mt8195: fix a missing check on list iterator
by Xiaomeng Tong 29 Mar '22

29 Mar '22

The bug is here: mt8195_etdm_hw_params_fixup(runtime, params); For the for_each_card_rtds(), just like list_for_each_entry(), the list iterator 'runtime' will point to a bogus position containing HEAD if the list is empty or no element is found. This case must be checked before any use of the iterator, otherwise it will lead to a invalid memory access. To fix the bug, use a new variable 'iter' as the list iterator, while use the original variable 'runtime' as a dedicated pointer to point to the found element.

[PATCH] soc: soc-dapm: fix two incorrect uses of list iterator
by Xiaomeng Tong 29 Mar '22

29 Mar '22

These two bug are here: list_for_each_entry_safe_continue(w, n, list, power_list); list_for_each_entry_safe_continue(w, n, list, power_list); After the list_for_each_entry_safe_continue() exits, the list iterator will always be a bogus pointer which point to an invalid struct objdect containing HEAD member. The funciton poniter 'w->event' will be a invalid value which can lead to a control-flow hijack if the 'w' can be controlled. The original intention was to break the outer list_for_each_entry_safe() loop if w->event is NULL, but forgot to *break* switch statement first. So just add a break to fix the bug.

[PATCH 00/14] ASoC: Intel: avs: Topology and path management
by Cezary Rojewski 28 Mar '22

28 Mar '22

A continuation of avs-driver initial series [1]. This chapter covers path management and topology parsing part which was ealier path of the main series. The two patches that represented these two subjects in the initial series, have been split into many to allow for easier review and discussion. AVS topology is split into two major parts: dictionaries - found within ASoC topology manifest - and path templates. Dictionaries job is to reduce the total amount of memory occupied by topology elements. Rather than having every pipeline and module carry its own information, each refers to specific entry in specific dictionary by provided (from topology file) indexes. In consequence, most struct avs_tplg_xxx are made out of pointers. Path templates are similar to path descriptions found in skylake-driver and they describe how given path shall look like in runtime - number of modules and pipelines that shape it and how they are laid out. A single path template is tied either to FE or BE and thus at most to a single, user-visible endpoint when speaking of FE. Path is a software representation of its ADSP firmware equivalent. It's a logical container for pipelines which are themselves containers - this time for modules i.e. processing units. Depending on the number of audio formats supported, each path template may carry one or more descriptions of given path. During runtime, when audio format is known, description matching said format is selected and used when instantiating path on ADSP firmware side through IPCs. Changes RFC -> v1: - Plenty of rewordings and spelling fixes as requested by Pierre - any sysfs-functionality-related left in RFC dropped, will be part of separate subject in the future - separated parsing of formatted strings into: "Support link_mask formatted string" patch, increasing series size to 14 patches [1]: https://lore.kernel.org/alsa-devel/20220207122108.3780926-1-cezary.rojewski… Cezary Rojewski (14): ASoC: Intel: avs: Declare vendor tokens ASoC: Intel: avs: Add topology parsing infrastructure ASoC: Intel: avs: Parse module-extension tuples ASoC: Intel: avs: Parse pplcfg and binding tuples ASoC: Intel: avs: Parse pipeline and module tuples ASoC: Intel: avs: Parse path and path templates tuples ASoC: Intel: avs: Add topology loading operations ASoC: Intel: avs: Support link_mask formatted string ASoC: Intel: avs: Declare path and its components ASoC: Intel: avs: Path creation and freeing ASoC: Intel: avs: Path state management ASoC: Intel: avs: Arm paths after creating them ASoC: Intel: avs: Prepare modules before bindings them ASoC: Intel: avs: Configure modules according to their type include/uapi/sound/intel/avs/tokens.h | 126 ++ sound/soc/intel/Kconfig | 2 + sound/soc/intel/avs/Makefile | 3 +- sound/soc/intel/avs/avs.h | 23 + sound/soc/intel/avs/path.c | 1008 ++++++++++++++++ sound/soc/intel/avs/path.h | 72 ++ sound/soc/intel/avs/topology.c | 1600 +++++++++++++++++++++++++ sound/soc/intel/avs/topology.h | 194 +++ 8 files changed, 3027 insertions(+), 1 deletion(-) create mode 100644 include/uapi/sound/intel/avs/tokens.h create mode 100644 sound/soc/intel/avs/path.c create mode 100644 sound/soc/intel/avs/path.h create mode 100644 sound/soc/intel/avs/topology.c create mode 100644 sound/soc/intel/avs/topology.h -- 2.25.1

[PATCH] ALSA: hda: Avoid unsol event during RPM suspending
by Mohan Kumar 28 Mar '22

28 Mar '22

There is a corner case with unsol event handling during codec runtime suspending state. When the codec runtime suspend call initiated, the codec->in_pm atomic variable would be 0, currently the codec runtime suspend function calls snd_hdac_enter_pm() which will just increments the codec->in_pm atomic variable. Consider unsol event happened just after this step and before snd_hdac_leave_pm() in the codec runtime suspend function. The snd_hdac_power_up_pm() in the unsol event flow in hdmi_present_sense_via_verbs() function would just increment the codec->in_pm atomic variable without calling pm_runtime_get_sync function. As codec runtime suspend flow is already in progress and in parallel unsol event is also accessing the codec verbs, as soon as codec suspend flow completes and clocks are switched off before completing the unsol event handling as both functions doesn't wait for each other. This will result in below errors [ 589.428020] tegra-hda 3510000.hda: azx_get_response timeout, switching to polling mode: last cmd=0x505f2f57 [ 589.428344] tegra-hda 3510000.hda: spurious response 0x80000074:0x5, last cmd=0x505f2f57 [ 589.428547] tegra-hda 3510000.hda: spurious response 0x80000065:0x5, last cmd=0x505f2f57 To avoid this, the unsol event flow should not perform any codec verb related operations during RPM_SUSPENDING state.

Bug 215711 - snd_hda_intel not binding to codec

I'm marking it as regression, since it used to work in the distant past (5.4-ish at least iirc) Could somebody take a look into this? Or was this discussed somewhere else already? Or even fixed? Anyway, to get this tracked: #regzbot introduced: v5.4..v5.10 #regzbot from: Petr Cerny <bugzilla(a)black-net.org> #regzbot title: snd: snd_hda_intel not binding to codec #regzbot link: https://bugzilla.kernel.org/show_bug.cgi?id=215711 Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I'm getting a lot of reports on my table. I can only look briefly into most of them and lack knowledge about most of the areas they concern. I thus unfortunately will sometimes get things wrong or miss something important. I hope that's not the case here; if you think it is, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight. -- Additional information about regzbot: If you want to know more about regzbot, check out its web-interface, the getting start guide, and the references documentation: https://linux-regtracking.leemhuis.info/regzbot/ https://gitlab.com/knurd42/regzbot/-/blob/main/docs/getting_started.md https://gitlab.com/knurd42/regzbot/-/blob/main/docs/reference.md The last two documents will explain how you can interact with regzbot yourself if your want to. Hint for reporters: when reporting a regression it's in your interest to CC the regression list and tell regzbot about the issue, as that ensures the regression makes it onto the radar of the Linux kernel's regression tracker -- that's in your interest, as it ensures your report won't fall through the cracks unnoticed. Hint for developers: you normally don't need to care about regzbot once it's involved. Fix the issue as you normally would, just remember to include 'Link:' tag in the patch descriptions pointing to all reports about the issue. This has been expected from developers even before regzbot showed up for reasons explained in 'Documentation/process/submitting-patches.rst' and 'Documentation/process/5.Posting.rst'.

[PATCH v2 1/2] ASoC: cs35l41: Add one more variable in the debug log
by Hui Wang 28 Mar '22

28 Mar '22

otp_map[].size is a key variable to compute the value of otp_val and to update the bit_offset, it is helpful to debug if could put it in the debug log.
