2021-01-26ALSA: hda/via: Apply the workaround generically for Clevo machinesTakashi Iwai
We've got another report indicating a similar problem wrt the power-saving behavior with VIA codec on Clevo machines. Let's apply the existing workaround generically to all Clevo devices with VIA codecs to cover all in once.

The "dai_id" given into LPAIF_INTFDMA_REG(...) is already the real DAI ID, not an index into v->dai_driver. Looking it up again seems entirely redundant. For IPQ806x (and SC7180 since commit 09a4f6f5d21c ("ASoC: dt-bindings: lpass: Fix and common up lpass dai ids") this is now often an out-of-bounds read because the indexes in the "dai_driver" array no longer match the actual DAI ID.

The easiest fix is to replace the 'depends' with a 'select' and have a single user selection to activate SoundWire on Intel platforms. This still allows regmap to be compiled independently as a module. This is just a temporary fix, the select/depend usage will be revisited and the SOF Kconfig re-organized, as suggested by Arnd Bergman.

The recently introduced sample rate validation code seems causing a problem on some devices; namely, after performing this, the bus gets screwed and it influences even on other USB devices. As a quick workaround, perform it only for the necessary devices; currently MOTU devices are known to need the valid altset checks, so filter out other devices.

2021-01-23ALSA: pcm: One more dependency for hw constraintsTakashi Iwai
The fix for a long-standing USB-audio bug required one more dependency variable to be added to the hw constraints. Unfortunately I didn't realize at debugging that the new addition may result in the overflow of the dependency array of each snd_pcm_hw_rule (up to three plus a sentinel), because USB-audio driver adds one more dependency only for a certain device and bus, hence it works as is for many devices. But in a bad case, a simple open always results in -EINVAL (with kernel WARNING if CONFIG_SND_DEBUG is set) no matter what is passed. Since the dependencies are real and unavoidable (USB-audio restricts the hw_params per looping over the format/rate/channels combos), the only good solution seems to raise the bar for one more dependency for snd_pcm_hw_rule -- so does this patch: now the hw constraint dependencies can be up to four.

Let's change the number of channels to be 3 instead of 4 so the math works out to have a max register of 0x67010, nicely fitting inside of the region size of 0x68000. Note: I tried to bump up the size of the register region to the next page to include the 0x68010 register but then the tail command caused SErrors with an async abort, implying that the register region doesn't exist or it isn't clocked because the bus is telling us that the register read failed. I reduce the number of channels and played audio through the HDMI channel and it kept working so I think this is correct.

2021-01-21Merge series "ASoC: qcom: Fix broken lpass driver" from Srinivas Kandagatla ↵Mark Brown
<srinivas.kandagatla@linaro.org>: LPASS driver is partially broken on DragonBoard DB410c on 5.10 and its totally broken on other Supported Qualcomm SoCs. This was due to DAI ids being over written by the SoC specific header files in the dt-bindings. Idea of having SoC specific headers is not doable when we are dealing with a common driver. So this patchset attempts to fix this properly by creating a common dt-bindings header for lpass which can be updated with new entries if required. This patchset also add an simple of_xlate function to resolve the dai names and different SoCs might not have 1:1 mapping for the dai_driver array with dai ids. Changes since v1: - removed array indexes as suggested by Stephan G. - rebased to sound/for-next branch - collected Srinivasa tested-by tag for sc7180 platform.

Sławiński<amadeuszx.slawinski@linux.intel.com>: This series adds unit tests for ASoC topology. First fix problems found when developing and running test cases and then add tests implementation. Tests themselves are quite simple and just call snd_soc_tplg_component_load() with various parameters and check the result. Tests themselves are described in more detail in commits adding them. Goal is to expand the amount of test cases in following patches. Prerequisity for this patchset are 2 patches which have already been sent: https://lore.kernel.org/alsa-devel/20210114163602.911205-1-amadeuszx.slawinski@linux.intel.com/T/#t Description on how typical test case itself works: In order to load topology we need to have 3 things: card, codec component & platform component. In typical test case we register card and platform component and bind to dummy codec. There are of course execeptions, when we want to test behaviour of topology API when component or card is missing. Note that this is bit different from typical scenario (in SOF and skylake drivers) where card is registered by machine driver and component by platform driver, as we register both when setting up test. If you check the test case most of them have similar architecture of: 1. /* run test */ ret = snd_soc_register_card(&kunit_comp->card); if (ret != 0 && ret != -EPROBE_DEFER) KUNIT_FAIL(test, "Failed to register card"); 2. ret = snd_soc_component_initialize(&kunit_comp->comp, &test_component, test_dev); KUNIT_EXPECT_EQ(test, 0, ret); 3. ret = snd_soc_add_component(&kunit_comp->comp, NULL, 0); KUNIT_EXPECT_EQ(test, 0, ret); Ad. 1. First we register card, which in most tests returns -EPROBE_DEFER (from snd_soc_bind_card()), as platform component is not yet created. I test for both 0 and -EPROBE_DEFER, as it makes it easier to reshuffle this code around if needed and there is one test case which does it in different order. Ad. 2. Then we initialize platform component with structure pointing at proper probe function, which calls snd_soc_tplg_component_load() with test parameters and checks expected result. Ad. 3. And then in follow up we call snd_soc_add_component() which creates platform component for us and calls snd_soc_try_rebind_card() which if everything is bound properly calls previously set probe function.

2021-01-20ALSA: usb-audio: Fix hw constraints dependenciesTakashi Iwai
Since the recent refactoring, it's been reported that some USB-audio devices (typically webcams) are no longer detected properly by PulseAudio. The debug session revealed that it's failing at probing by PA to try the sample rate 44.1kHz while the device has discrete sample rates other than 44.1kHz. But the puzzle was that arecord works as is, and some other devices with the discrete rates work, either. After all, this turned out to be the lack of the dependencies in a few hw constraint rules: snd_pcm_hw_rule_add() has the (variable) arguments specifying the dependent parameters, and some functions didn't set the target parameter itself as the dependencies. This resulted in an invalid parameter that could be generated only in a certain call pattern. This bug itself has been present in the code, but it didn't trigger errors just because the rules were casually avoiding such a corner case. After the recent refactoring and cleanup, however, the hw constraints work "as expected", and the problem surfaced now. For fixing the problem above, this patch adds the missing dependent parameters to each snd_pcm_hw_rule() call.

lpass hdmi support patch totally removed support for MI2S TERTIARY and QUATERNARY. One of the major issue was spotted with the design of having separate SoC specific header files for the common lpass driver. This design is prone to break as an when new SoC header is added as the common DAI ids of other SoCs will be overwritten by the new ones. Having a common header qcom,lpass.h should fix the issue and any new DAI ids should be added to the common header. With this change lpass also needs a new of_xlate function to resolve dai name.

2021-01-19ALSA: hda: Balance runtime/system PM if direct-complete is disabledKai-Heng Feng
After hibernation, HDA controller can't be runtime-suspended after commit 215a22ed31a1 ("ALSA: hda: Refactor codjc PM to use direct-complete optimization"), which enables direct-complete for HDA codec. The HDA codec driver didn't expect direct-complete will be disabled after it returns a positive value from prepare() callback. However, there are some places that PM core can disable direct-complete. For instance, system hibernation or when codec has subordinates like LEDs. So if the codec is prepared for direct-complete but PM core still calls codec's suspend or freeze callback, partially revert the commit and take the original approach, which uses pm_runtime_force_*() helpers to ensure PM refcount are balanced. Meanwhile, still keep prepare() and complete() callbacks to enable direct-complete and request a resume for jack detection, respectively. Reported-by: Kenneth R.

2021-01-18ALSA: usb-audio: Avoid implicit feedback on Pioneer devicesTakashi Iwai
For addressing the regression on Pioneer devices, we recently corrected the quirk code to enable the implicit feedback mode on those devices properly. However, the devices still showed problems with the full duplex operations with JACK, and after debug sessions, we figured out that the older kernels that had worked with JACK also didn't use the implicit feedback mode at all although they had the quirk code to enable it; instead, the old code worked just to skip the normal sync endpoint setup that would have been detected without it. IOW, what broke without the implicit-fb quirk in the past was the application of the normal sync endpoint that is actually the capture data endpoint on these devices. This patch covers the overseen piece: it modifies the quirk code again not to enable the implicit feedback mode but just to make the driver skipping the sync endpoint detection. This made the driver working with JACK full-duplex mode again. Still it's not quite clear why the implicit feedback doesn't work on those devices yet; maybe it's about some issues in the URB setup. But at least, with this patch, the driver should work in the level of the older kernels again.

2021-01-18ALSA: usb-audio: Set sample rate for all sharing EPs on UAC1Takashi Iwai
The UAC2/3 sample rate setup is based on the clock node, which is usually shared in the interface, and can't be re-setup without deselecting the interface once, and that's how the current code behaves. OTOH, the sample rate setup of UAC1 is per endpoint, hence we basically need to call for each endpoint usage even if those share the same interface. This patch fixes the behavior of UAC1 to call always snd_usb_init_sample_rate() in snd_usb_endpoint_configure().

2021-01-18ALSA: usb-audio: Fix UAC1 rate setup for secondary endpointsTakashi Iwai
The current sample rate setup function for UAC1 assumes only the first endpoint retrieved from the interface:altset pair, but the rate set up may be needed also for the secondary endpoint. Also, retrieving the endpoint number from the interface descriptor is redundant; we have already the target endpoint in the given audioformat object. This patch simplifies the code and corrects the target endpoint as described in the above. It simply refers to fmt->endpoint directly. Also, this patch drops the pioneer_djm_set_format_quirk() that is caleld from snd_usb_set_format_quirk(); this function does the sample rate setup but for the capture endpoint (0x82), and that's exactly what the change above fixes.

2021-01-13ALSA: usb-audio: Always apply the hw constraints for implicit fb syncTakashi Iwai
Since the commit 5a6c3e11c9c9 ("ALSA: usb-audio: Add hw constraint for implicit fb sync"), we apply the hw constraints for the implicit feedback sync to make the secondary open aligned with the already opened stream setup. This change assumed that the secondary open is performed after the first stream has been already set up, and adds the hw constraints to sync with the first stream's parameters only when the EP setup for the first stream was confirmed at the open time. However, most of applications handling the full-duplex operations do open both playback and capture streams at first, then set up both streams. This results in skipping the additional hw constraints since the counter-part stream hasn't been set up yet at the open of the second stream, and it eventually leads to "incompatible EP" error in the end. This patch corrects the behavior by always applying the hw constraints for the implicit fb sync. The hw constraint rules are defined so that they check the sync EP dynamically at each invocation, instead. This covers the concurrent stream setups better and lets the hw refine calls resolving to the right configuration. Also this patch corrects a minor error that has existed in the debug print that isn't built as default.

2021-01-13ASoC: SOF: Intel: fix page fault at probe if i915 init failsKai Vehmanen
The earlier commit to fix runtime PM in case i915 init fails, introduces a possibility to hit a page fault. snd_hdac_ext_bus_device_exit() is designed to be called from dev.release(). Calling it outside device reference counting, is not safe and may lead to calling the device_exit() function twice. Additionally, as part of ext_bus_device_init(), the device is also registered with snd_hdac_device_register(). Thus before calling device_exit(), the device must be removed from device hierarchy first. Fix the issue by rolling back init actions by calling hdac_device_unregister() and then releasing device with put_device(). This matches with existing code in hdac-ext module. To complete the fix, add handling for the case where hda_codec_load_module() returns -ENODEV, and clean up the hdac_ext resources also in this case. In future work, hdac-ext interface should be extended to allow clients more flexibility to handle the life-cycle of individual devices, beyond just the current snd_hdac_ext_bus_device_remove(), which removes all devices.

However, mute/micmute LED will clear codec's direct-complete flag by dpm_clear_superiors_direct_complete(). This doesn't play well with SOF driver. When its runtime resume is called for system suspend, hda_codec_jack_check() schedules jackpoll_work which uses snd_hdac_is_power_on() to check whether codec is suspended. Because the direct-complete path isn't taken, pm_runtime_disable() isn't called so snd_hdac_is_power_on() returns false and jackpoll continues to run, and snd_hda_power_up_pm() cannot power up an already suspended codec in multiple attempts, causes the long delay on system suspend: if (dev->power.direct_complete) { if (pm_runtime_status_suspended(dev)) { pm_runtime_disable(dev); if (pm_runtime_status_suspended(dev)) { pm_dev_dbg(dev, state, "direct-complete "); goto Complete; } pm_runtime_enable(dev); } dev->power.direct_complete = false; } When direct-complete path is taken, snd_hdac_is_power_on() returns true and hda_jackpoll_work() is skipped by accident. So this is still not correct. If we were to use snd_hdac_is_power_on() in system PM path, pm_runtime_status_suspended() should be used instead of pm_runtime_suspended(), otherwise pm_runtime_{enable,disable}() may change the outcome of snd_hdac_is_power_on(). Because devices suspend in reverse order (i.e. child first), it doesn't make much sense to resume an already suspended codec from audio controller. So avoid the issue by making sure jackpoll isn't used in system PM process.

2021-01-12ALSA: hda/tegra: fix tegra-hda on tegra30 socPeter Geis
Currently hda on tegra30 fails to open a stream with an input/output error. For example: speaker-test -Dhw:0,3 -c 2 speaker-test 1.2.2 Playback device is hw:0,3 Stream parameters are 48000Hz, S16_LE, 2 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 64 to 16384 Period size range from 32 to 8192 Using max buffer size 16384 Periods = 4 was set period_size = 4096 was set buffer_size = 16384 0 - Front Left Write error: -5,Input/output error xrun_recovery failed: -5,Input/output error Transfer failed: Input/output error The tegra-hda device was introduced in tegra30 but only utilized in tegra124 until recent chips. Tegra210/186 work only due to a hardware change. For this reason it is unknown when this issue first manifested. Discussions with the hardware team show this applies to all current tegra chips. It has been resolved in the tegra234, which does not have hda support at this time. The explanation from the hardware team is this: Below is the striping formula referenced from HD audio spec. { ((num_channels * bits_per_sample) / number of SDOs) >= 8 } The current issue is seen because Tegra HW has a problem with boundary condition (= 8) for striping. The reason why it is not seen on Tegra210/Tegra186 is because it uses max 2SDO lines. Max SDO lines is read from GCAP register. For the given stream (channels = 2, bps = 16); ratio = (channels * bps) / NSDO = 32 / NSDO; On Tegra30, ratio = 32/4 = 8 (FAIL) On Tegra210/186, ratio = 32/2 = 16 (PASS) On Tegra194, ratio = 32/4 = 8 (FAIL) ==> Earlier workaround was applied for it If Tegra210/186 is forced to use 4SDO, it fails there as well. So the behavior is consistent across all these chips. Applying the fix in [1] universally resolves this issue on tegra30-hda. Tested on the Ouya game console and the tf201 tablet.
