This patch adds DP-MST support for GK104+ NVIDIA codecs. GK104+ NVIDIA codecs support DP-MST audio. These codecs have 4 output converters and 4 pin widgets, with 4 device entries per pin widget for a total of 16 device entries. This patch moves the existing patch_nvhdmi() definition to patch_nvhdmi_legacy(), used by pre-GK104 NVIDIA codecs. Redefine patch_nvhdmi() to enable DP-MST support by setting codec->dp_mst and spec->dyn_pcm_assign. Introduce fresh logic for dynamic pcm assignment, making sure that new pcm assignments are compatible with the legacy static per_pin-pmc assignment that existed in the days before DP-MST.

This patch make it possible for non-acomp codecs to set dyn_pcm_assign/dp_mst and get DP-MST audio support. Document change notification HDA040-A for the Intel High Definition Audio 1.0a specification introduces a Device Select verb for Digital Display Pin Widgets that are multi-stream capable. This verb selects a Device Entry that is used by subsequent Pin Widget verbs. Once the Device Entry is selected, all subsequent Pin Widget verbs controlling the sink device will be directed to the selected Device Entry until the Device Select verb is updated with a new value. These Pin Widget verbs include: * Connection Select * Get Connection List Entry * Amplifier Gain/Mute * Power State * Pin Widget Control * ELD Data * DIP-Size * DIP-Index * DIP-Data * DIP-XmitCtrl * Content Protection Control * ASP Channel Mapping This patch adds calls to snd_hda_set_dev_select() to direct each of these Pin Widget control verbs to the correct Device Entry. snd_hda_get_connections() does not return per-device connection list, therefore make use snd_hda_get_raw_connections() instead of snd_hda_get_connections().

This patch adds DP-MST jack support which will be used on NVIDIA platforms. Today, DP-MST audio is supported only if the codec has acomp support. This patch makes it possible to add DP-MST support for non-acomp codecs. For the codecs supporting DP-MST audio, each pin can contain several device entries. Each device entry is a virtual pin, described by pin_nid and dev_id in struct hdmi_spec_per_pin. For monitor hotplug event handling, non-acomp codecs enable and register jack-detection for every hdmi_spec_per_pin. This patch updates every relevant function in hda_jack.h and its implementation in hda_jack.c, to consider dev_id along with pin_nid. Changes to the HD Audio specification to support DP-MST audio are described in the Intel Document Change Notification (DCN) number HDA040-A. From HDA040-A, "For the case of multi stream capable Digital Display Pin Widget, [the Get Pin Sense verb] can be used to read a specific Device Entry state as reported in Get Device List Entry verb." This patch updates the read_pin_sense() function to take the dev_id as an argument and pass it as a parameter to the Get Pin Sense verb. Bits 15 through 20 from the Unsolicited Response for intrinsic events contain the index of the Device Entry that generated the event. This patch updates the Unsolicited Response event handlers to extract the device entry index from the response and pass it to snd_hda_jack_tbl_get_from_tag(). This patch updates snd_hda_jack_tbl_new() to take a dev_id argument and store it in the jack structure, and to make sure not to generate a different tag when called more than once for the same nid.

Remove the workarounds added in commit fa763f1b ("ALSA: hda - Force polling mode on CNL for fixing codec communication") and commit a8d7bde2 ("ALSA: hda - Force polling mode on CFL for fixing codec communication"). The workarounds are no longer needed after the more generic change done in commit 2756d914 ("ALSA: hda - Fix intermittent CORB/RIRB stall on Intel chips"). This change applies to a larger set of hardware and covers CFL and CNL as well. Similar change was already done to SOF DSP HDA driver with no regressions detected. Signed-off-by:

Kai Vehmanen authored
Semantics of port#0 differ between ICL and TGL: ICL port#0 -> never used for HDAudio ICL port#1 -> should be mapped to first pin (0x04) TGL port#0 -> typically not used, but HW has the support, so should be mapped to first pin (0x04) TGL port#1 -> should be mapped to 2nd pin (0x06) Refactor the port mapping logic to allow to take the above differences into account. Fixes issues with HDAudio on some TGL platforms. Co-developed-by:

The unit descriptor validation may lead to a probe error when the device provides a buggy descriptor or the validator detected incorrectly. For identifying such an error and band-aiding, give a new module option, skip_validation. With this option, the driver ignores the validation errors with the hexdump of the unit descriptor, so we can check it in a bit more details.

While output urb's snd_complete_urb() is executing, calling prepare_outbound_urb() may cause endpoint stopped before prepare_outbound_urb() returns and result in next urb submitted to stopped endpoint. usb-audio driver cannot re-use it afterwards as the urb is still hold by usb stack. This change checks EP_FLAG_RUNNING flag after prepare_outbound_urb() again to let snd_complete_urb() know the endpoint already stopped and does not submit next urb. Below kind of error will be fixed: [ 213.153103] usb 1-2: timeout: still 1 active urbs on EP #1 [ 213.164121] usb 1-2: cannot submit urb 0, error -16: unknown error Signed-off-by:

For non-x86 architectures, SNDRV_DMA_TYPE_DEV_UC should be treated equivalent with SNDRV_DMA_TYPE_DEV, where the default mmap handler still checks only about SNDRV_DMA_TYPE_DEV. Make the check more proper. Note that all existing users of *_UC buffer types are x86-only, so this doesn't fix any bug, but just for consistency.

When a new timer instance is created and assigned to the active link in snd_timer_open(), the caller still doesn't (can't) set its callback and callback data. In both the user-timer and the sequencer-timer code, they do manually set up the callbacks after calling snd_timer_open(). This has a potential risk of race when the timer instance is added to the already running timer target, as the callback might get triggered during setting up the callback itself. This patch tries to address it by changing the API usage slightly: - An empty timer instance is created at first via the new function snd_timer_instance_new(). This object isn't linked to the timer list yet. - The caller sets up the callbacks and others stuff for the new timer instance. - The caller invokes snd_timer_open() with this instance, so that it's linked to the target timer. For closing, do similarly: - Call snd_timer_close(). This unlinks the timer instance from the timer list. - Free the timer instance via snd_timer_instance_free() after that. Signed-off-by:
