This patch adds extra init functions for the Sound Blaster Z and Recon3Di. It also adds more checks to make sure that the DSP isn't downloaded twice on startup, by checking if the dsp_state is already set to DSP_DOWNLOADED. It also adds the ability to re-download the DSP on a resume. It also changes the init verbs table to apply to all codecs, and takes the two specific end verbs and puts them into a separate function in ca0132_init instead. GPIO functions are also added.

This patch adds extra functions for shutdown on the Sound Blaster Z and Recon3Di. The Recon3Di only has one specific functions, which sets the GPIO data pins to 0 to prevent a popping noise. The Sound Blaster Z exit sequence was taken from Windows. Without this exit function, the card will not reload properly unless the PC has been shutdown to clear the onboard memory. There are commented out functions currently in the sbz_exit_chip function that are added in a later patch. Also, a reboot notify function has been added, to make sure these functions are ran before a reboot. This helps when using the card through VFIO in a virtual machine, to make sure the card reloads the DSP properly. Signed-off-by:

This patch adds iomapping for the region2 section of memory on the SBZ. This memory region is used in later patches for setting inputs and outputs. If the mapping fails, the quirk is changed back to QUIRK_NONE to avoid attempts to write to uninitialized memory. It also adds a new exit sequence to unmap the iomem for the SBZ.

This patch adds an unsolicited response tag for the front headphone panel which uses the same hp_callback as the rear headphone detection. This patch also adds pincfgs for the R3Di and SBZ which were taken from the Windows driver. The pins are also defined in the function ca0132_config. Both the R3Di and SBZ are also given a max out channel value of 6 to handle 5.1 surround sound in later patches. Signed-off-by:

This patch adds PCI quirk ID's for the Sound Blaster Z and Recon3Di. Only the currently tested ID's have been added. This patch also adds the ability to load alternative firmwares for each card, the firmwares can be obtained from within the Windows driver. The Recon3Di uses "ctefx-r3di.bin" and the Sound Blaster Z uses "ctefx-sbz.bin". If the alternative firmware for the given quirk is not found, the original ctefx.bin will be used. This has been confirmed to work for both the R3Di and the SBZ. This patch also makes the character array *dirstr a const. Signed-off-by:

Recently released USB Audio Class 3.0 specification contains BADD (Basic Audio Device Definition) document which describes pre-defined UAC3 configurations. BADD support is mandatory for UAC3 devices, it should be implemented as a separate USB device configuration. As per BADD document, class-specific descriptors shall not be included in the Device’s Configuration descriptor ("inferred"), but host can guess them from BADD profile number, number of endpoints and their max packed sizes. This patch adds support of all BADD profiles from the spec Signed-off-by:Ruslan Bilovol <ruslan.bilovol@gmail.com> Tested-by:

The snd_pcm_stream_lock_irq*() functions decouple disabling interrupts from the actual locking process. This does not work as expected if the locking primitives are replaced like on preempt-rt. Provide one function for locking which uses correct locking primitives. Signed-off-by:

Functions like snd_usb_copy_string_desc() or get_term_name() don't actually need mixer_build state but can use snd_usb_audio structure instead to get usb device. This patch has no functional change but prepares to future UAC3 BADD profiles support which don't have class-specific descriptors so won't have mixer_build state. Signed-off-by:

Move class-specific parts of uac1/2 parsing to separate function which now produce audioformat structure that is ready to be fed to snd_usb_add_audio_stream(). This also broke Blue Microphones workaround (which relies on audioformat decoded from previous altsetting) into two parts: prepare quirk flag analyzing previous altsetting then use it with current altsetting.

Offload snd_usb_parse_audio_interface() function which became quite long after adding UAC3 spec support. Move audioformat allocation and initialization into separate function, this will make easier future refactoring. Attributes left in the original func because it'll be used for UAC3 BADD profiles suport in the future There is no functional change. Signed-off-by:

Introduce a new macro for iterating over mixer element list for avoiding the open codes in many places. Also the open-coded container_of() and the forced cast to struct usb_mixer_elem_info are replaced with another simple macro, too. No functional changes but just readability improvement.

Dell WD15 Dock with 0bda:4014 doesn't give any useful strings for the vendor and the product names. Name them more specifically via quirk, as well as the UCM profile name. Signed-off-by: -
Takashi Iwai authored
Historically USB-audio driver sets the card's longname field with the details of the device and the bus information. It's good per se, but not preferable when it's referred as the identifier for UCM profile. This patch adds a quirk profile_name field to override the card's longname string to a pre-defined one, so that one can create a unique and consistent ID string for the specific USB device via a quirk table to be used as a UCM profile name. The patch does a slight code refactoring to split out the functions to set shortname and longname fields as well. Signed-off-by: -

This patch adds "Keep Interface" control for each USB-audio device. The control element is with SND_CTL_IFACE_CARD, so that it won't appear on any sane mixer applications. For a device that is confirmed to work well with "keep-interface" mode, user can flip the control via amixer, e.g. % amixer -c1 cset iface=CARD,name='Keep Interface' on and save/restore the state via alsactl. The reason to provide this via control API is that the behavior must be pretty depending on the device (and the firmware in it), so it's not ideal to apply via module option. For a device that certainly works, we may set it statically via a quirk table entry. But a device like Dell WD15 dock behaves so differently depending on the firmware, and we can't set it statically. So leave this as a dynamic switch each user can adjust freely. Signed-off-by: -

Introduce a new flag to struct snd_usb_audio for allowing the device to skip usb_set_interface() calls at changing or closing the stream. As of this patch, the flag is nowhere set, so it's just a place holder. The dynamic switching will be added in the following patch. A background information for this change: Dell WD15 dock with Realtek chip gives a very long pause at each time the driver changes the altset, which eventually happens at every PCM stream open/close and parameter change. As the long pause happens in each usb_set_interface() call, there is nothing we can do as long as it's called. The workaround is to reduce calling it as much as possible, and this flag indicates that behavior. Signed-off-by: -

This is a preliminary change for the upcoming quirk implementation. Currently USB-audio driver tries to call usb_set_interface() whenever the format change with interface/altset modification happens. In this patch, the check is replaced with the comparison of cur_altsetting and the targeted altsetting pointer, so that the driver may skip the unnecessary function calls. Signed-off-by: -

In the early commit adcdd0d5 ("ALSA: usb-audio: Skip volume controls triggers hangup on Dell USB Dock"), we add the mixer quirks for Dell dock to skip two mixer FU's for playback. This supposed that the device has always the proper initial volume, but it doesn't seem always correct. This patch adds the explicit initialization of the volumes to the fixed 0dB at the device probe time. Also, such a fixup is needed after the resume, so a new function is hooked to the resume callback as well. Bugzilla: http://bugzilla.suse.com/show_bug.cgi?id=1089467Signed-off-by:

At present, to add PCM substreams for each of available tx/rx streams, this driver uses a condition based on model-name. This is not enough to support unknown models. In former commits, this driver gains cache of stream formats. For models which support protocol extension, all of available steam formats are cached. For known models, hard-coded stream formats are used to generate the cache. For unknown models, stream formats at current mode of sampling transmission frequency is cached. Anyway, at least, the cached formats are used to expose constrains of PCM substreams for userspace applications. Thus, The cached data can be also used to add PCM substreams themselves, instead of the name-based conditions. This commit obsoletes local frag of force_two_pcms. Signed-off-by:

In former commits, proxy structure gets members for cache of stream formats. The cache allows to apply correct constraints and rules to runtime of PCM substream. They allows userspace applications to change current sampling transmission frequency. This commit uses the cacher for the PCM constraints and rules. Signed-off-by:

At present, to check running stream, available stream formats are used at current sampling transmission frequency (stf). But when changing stf, it's convenient to use cache of stream formats. This commit applies this idea. Signed-off-by:

TC Applied Technologies (TCAT) have added extension to DICE protocol. This protocol extension is called as Extended Application Protocol, a.k.a. EAP. In this protocol extension, units get additional 9 address spaces. One of it is for current configuration. In this address space, a pair of router and stream formats are exposed per mode of three sampling transmission frequencies. This commit adds support the protocol extension for address space of the current configuration to generate cache of stream formats. Signed-off-by:

Alesis shipped some models with DICE ASICs. All of them just support DICE original protocol and drivers can't retrieve all of available stream formats without changing status of sampling transmission frequency actually. This commit puts some hard-coded parameters for the models. When detecting the models, the corresponding parameters are copied as cache of stream formats. I note that each of pair of iO14/iO26 and MultiMix 8/12/16 has the same model ID on their configuration ROM. The MultiMix 8/12/16 just support one mode for sampling transmission frequency and ALSA dice driver already handles them correctly. The iO14/iO26 support three modes and need hard-coded parameters. To distinguish these two models, this commit let the driver to retrieve current stream formats and compare it to known parameters, then decide it. Signed-off-by:

Unlike the other drivers in ALSA firewire stack, ALSA dice driver does't create 'firewire' directory for proc nodes because it has 'dice' node only. But this is inconvenient because I have a plan to add another proc node to output available stream formats from cache. This commit let the driver to create the directory and put 'dice' node into it.

A previous commit 6f688268 ('ALSA: dice: purge generating channel cache') purged cache of stream formats. DICE interface originally has no feature to assist drivers to retrieve available formats for all of supported sampling transmission frequencies, without changing the frequency actually. For later release of Dice ASICs such as TCD2210, Dice interface has extended protocol and can support the feature. This assists drivers to retrieve available stream formats. This commit is a first step to regain the cache to generate PCM rules for all of supported sampling transmission frequencies. Signed-off-by:
