bmAtributes offset doesn't exist in the UAC3 CS_EP descriptor. Hence, checking for pitch control as if it was UAC2 doesn't make any sense. Use the defined UAC3 offsets instead. Fixes: 9a2fe9b8 ("ALSA: usb: initial USB Audio Device Class 3.0 support") Signed-off-by:

A commit 08f9f448 ('ALSA: core api: define offsets for TLV items') introduced a series of macro for offset of db-scale type of TLV, however there are some types of TLV to add similar macros. This commit complements macros for offset of db-minmax and db-linear types of TLV data. Cc: Ranjani Sridharan <ranjani.sridharan@linux.intel.com> Signed-off-by:

Currently, there are no pre-defined accessors for the elements in topology TLV data. In the absence of such offsets, the tlv data will have to be decoded using hardwired offset numbers 0-N depending on the type of TLV. This patch defines accessor offsets for the type, length, min and mute/step items in TLV data for DB_SCALE type tlv's. These will be used by drivers to decode the TLV data while loading topology thereby improving code readability. The type and len offsets are common for all TLV types. The min and step/mute offsets are specific to DB_SCALE tlv type. Signed-off-by:

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:

In snd_ctl_elem_add_compat(), the fields of the struct 'data' need to be copied from the corresponding fields of the struct 'data32' in userspace. This is achieved by invoking copy_from_user() and get_user() functions. The problem here is that the 'type' field is copied twice. One is by copy_from_user() and one is by get_user(). Given that the 'type' field is not used between the two copies, the second copy is *completely* redundant and should be removed for better performance and cleanup. Also, these two copies can cause inconsistent data: as the struct 'data32' resides in userspace and a malicious userspace process can race to change the 'type' field between the two copies to cause inconsistent data. Depending on how the data is used in the future, such an inconsistency may cause potential security risks. For above reasons, we should take out the second copy. 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:

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:
