To be able to support different firmwares and tuning for different models, the driver needs to be able to load a different firmware and coefficient file based on its Subsystem ID. The driver attempts to load the firmware in the following order: /lib/firmware/cirrus/cs35l41-dsp1-<fw-type>-<ssid>-dev<#>.wmfw /lib/firmware/cirrus/cs35l41-dsp1-<fw-type>-<ssid>.wmfw /lib/firmware/cirrus/cs35l41-dsp1-<fw-type>.wmfw Signed-off-by:

The Subsystem ID is read from the HDA driver, and will be used by the CS35L41 driver to be able to uniquely identify the laptop, which is required to be able to define firmware to be used by specific models. Signed-off-by:

This patch adds support for the CS35L41 DSP. The DSP allows for extra features, such as running speaker protection algorithms and hibernations. To utilize these features, the driver must load firmware into the DSP, as well as various tuning files which allow for customization for specific models.

The cs35l41 part contains a DSP which is able to run firmware. The cs_dsp library can be used to control the DSP. These controls can be exposed to userspace using ALSA controls. This library adds apis to be able to interface between cs_dsp and hda drivers and expose the relevant controls as ALSA controls. [ Note: the dependency of CONFIG_SND_HDA_CS_DSP_CONTROLS Kconfig is corrected. Also, this Kconfig isn't enabled now but will be actually enabled in a later patch -- tiwai ] Signed-off-by:

Use atomic_try_cmpxchg instead of atomic_cmpxchg (*ptr, old, new) == old in ep_state_update. x86 CMPXCHG instruction returns success in ZF flag, so this change saves a compare after cmpxchg (and related move instruction in front of cmpxchg). No functional change intended. Signed-off-by:

If early probe of HDAudio bus driver fails e.g.: due to missing firmware file, snd_hda_codec_shutdown() ends in manipulating uninitialized codec->pcm_list_head causing page fault. Iinitialization of HDAudio codec in ASoC is split in two: - snd_hda_codec_device_init() - snd_hda_codec_device_new() snd_hda_codec_device_init() is called during probe_codecs() by HDAudio bus driver while snd_hda_codec_device_new() is called by codec-component's ->probe(). The second call will not happen until all components required by related sound card are present within the ASoC framework. With firmware failing to load during the PCI's deferred initialization i.e.: probe_work(), no platform components are ever registered. HDAudio codec enumeration is done at that point though, so the codec components became registered to ASoC framework, calling snd_hda_codec_device_init() in the process. Now, during platform reboot snd_hda_codec_shutdown() is called for every codec found on the HDAudio bus causing oops if any of them has not completed both of their initialization steps. Relocating field initialization fixes the issue. Signed-off-by:

AVS HDAudio bus driver does not tie with codec drivers tighly. Codec device and its respective driver cleanup procedures are split and may not occur one after the other. Device cleanup is performed only on snd_hdac_ext_bus_device_remove() i.e. it's the bus driver's responsibility. If codec component probing fails, put_device() found in snd_hda_codec_device_new() may lead to page fault. Relocate it to snd_hda_codec_new() to address the problem on ASoC side while keeping status quo for snd_hda_intel. Signed-off-by:

AVS HDAudio bus driver does not tie with codec drivers tighly and snd_hda_codec_device_new() can be called after codec's module reload. In such case, rpm is forbidden and invoking pm_runtime_forbid() unconditionally causes device's usage_count to become unbalanced. This is later caught by WARN_ON() found in sound/soc/hda.c. Detect such circumstance and bump the usage_count instead. Signed-off-by:

If snd_hda_hdmi_codec module is denylisted and any event causes i915 enumeration to fail, is_likely_hdmi_codec() ends in null-ptr-deref. As snd_soc_hda is an ASoC-based driver, its initialization is delayed until all the necessary components appear in the system - allowing actual sound card to enumerate. snd_hda_codec_configure() gets called by the avs-driver core during probe_codecs() but the snd_hda_codec_device_new(), necessary to complete codecs initialization, happens only when codec-component of hda sound card is being probed. Denylisting snd_hda_codec_hdmi module causes snd_hda_codec_configure() to reach: codec_bind_generic() -> is_likely_hdmi_codec() which makes use of ->wcaps and at this point the it isn't initialized yet - again, requires completion of snd_hda_codec_device_new().

sparse reports sound/pci/hda/patch_cs8409-tables.c:79:25: warning: symbol 'cs8409_cs42l42_pincfgs_no_dmic' was not declared. Should it be static? cs8409_cs42l42_pincfgs_no_dmic is only used by cs8409_fixups table as an initializer for the hda_fixup element v.pins. Both are defined in the patch_cs8408-table.c file but only cs8409_fixups is used externally in patch_cs8409.c. So cs8409_cs42l42_pincfgs_no_dmic should have a static storage class specifier. The other v.pins initializers in cs8409_fixups table, though declared extern in patch_cs8409.h are also only used in patch_cs8409-tables.c. So change all the v.pins initializers to static.

The TRACE_EVENT() macro is broken up into various parts to be efficient. The TP_fast_assign() is just to record the event into the ring buffer, and is to be done as fast as possible as this occurs during the actual running of the code. The slower this is, the slower the code that is being traced becomes. The TP_printk() is processed when reading the tracing buffer. This is considered the slow path. Any processing that can be moved from the TP_fast_assign() to the TP_printk() should do so. For some reason, the entire string processing of the trace events hda_send_cmd, hda_get_response, and hda_unsol_event was moved from the TP_printk() into the TP_fast_assign(). On top of that, the __dynamic_array() was used with a fixed size of HDAC_MSG_MAX, which is useless as a dynamic_array as it will always allocate HDAC_MSG_MAX bytes on the ring buffer and even save that amount into the event (as it expects the size to be dynamic, which using a fixed size defeats that purpose). Instead, just save the necessary elements in the TP_fast_assign() and do the string manipulation in the slow path. The output should be the same. Signed-off-by:

This removes the need to power cycle the Dell WD15 dock if it has been attached to a Windows machine. The Windows driver puts the ALC4020 USB audio controller into 'manual mode', and then does all the power management and other configuration itself, by sending HD audio commands directly to the ALC3263 audio codec via vendor-type USB messages. If manual mode is off, this is all handled by the firmware, and works well enough. If manual mode is turned on, the latency of the SET INTERFACE command goes from several hundred ms to less than 1 ms (see https://bugzilla.suse.com/show_bug.cgi?id=1089467), but I'm not sure if the additional code that would be required is worth it. Funnily enough, the Windows driver tries to turn off manual mode when the dock is disconnected, which doesn't work for obvious reasons. Additionally, fix a bug in dell_dock_init_vol, which didn't work because the Control Selector was missing. Now, it properly resets the volume to 0dB.

The Dell WD15 dock has a headset and a line out port. Add support for detecting if a jack is inserted into one of these ports. For the headset jack, additionally determine if a mic is present. The WD15 contains an ALC4020 USB audio controller and ALC3263 audio codec from Realtek. It is a UAC 1 device, and UAC 1 does not support jack detection. Instead, jack detection works by sending HD Audio commands over vendor-type USB messages. I found out how it works by looking at USB captures on Windows. The audio codec is very similar to the one supported by sound/soc/codecs/rt298.c / rt298.h, some constant names and the mic detection are adapted from there. The realtek_add_jack function is adapted from build_connector_control in sound/usb/mixer.c. I tested this on a WD15 dock with the latest firmware. Signed-off-by:

The patch applies the same quirks used for SC-01 at firmware v1.1.0 to the ones running v1.0.0, with respect to hard-coded sample rates. I got two more units and successfully tested the patch series with both firmwares. The support is now complete (not accounting ASIO). Signed-off-by:

Fiero SC-01 is a USB sound card with two mono inputs and a single stereo output. The inputs are composed into a single stereo stream. The device uses a vendor-provided driver on Windows and does not work at all without it. The driver mostly provides ASIO functionality, but also alters the way the sound card is queried for sample rates and clocks. ALSA queries those failing with an EPIPE (same as Windows 10 does). Presumably, the vendor-provided driver does not query it at all, simply matching by VID:PID. Thus, I consider this a buggy firmware and adhere to a set of fixed endpoint quirks instead. The soundcard has an internal clock. Implicit feedback mode is required for the playback. I have updated my device to v1.1.0 from a Windows 10 VM using a vendor- provided binary prior to the development, hoping for it to just begin working. The device provides no obvious way to downgrade the firmware, and regardless, there's no binary available for v1.0.0 anyway. Thus, I will be getting another unit to extend the patch with support for that. Expected to be a simple copy-paste of the existing one, though. There were no previous reports of that device in context of Linux anywhere. Other issues have been reported though, but that's out of the scope. Signed-off-by:
