* ALSA: usb-audio: Extend DragonFly dB scale quirk to cover other variantsAnssi Hannula2016-09-231-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | The DragonFly quirk added in 42e3121d90f4 ("ALSA: usb-audio: Add a more accurate volume quirk for AudioQuest DragonFly") applies a custom dB map on the volume control when its range is reported as 0..50 (0 .. 0.2dB). However, there exists at least one other variant (hw v1.0c, as opposed to the tested v1.2) which reports a different non-sensical volume range (0..53) and the custom map is therefore not applied for that device. This results in all of the volume change appearing close to 100% on mixer UIs that utilize the dB TLV information. Add a fallback case where no dB TLV is reported at all if the control range is not 0..50 but still 0..N where N <= 1000 (3.9 dB). Also restrict the quirk to only apply to the volume control as there is also a mute control which would match the check otherwise.

* ALSA: usb-audio: Add sanity checks for endpoint accessesTakashi Iwai2016-03-161-0/+4
| | | | | | | | | | | | Add some sanity check codes before actually accessing the endpoint via get_endpoint() in order to avoid the invalid access through a malformed USB descriptor. Mostly just checking bNumEndpoints, but in one place (snd_microii_spdif_default_get()), the validity of iface and altsetting index is checked as well.

* ALSA: usb-audio: Fix mixer ctl regression of Native Instrument devicesTakashi Iwai2016-01-131-1/+1
| | | | | | | | | | | | The commit [da6d276957ea: ALSA: usb-audio: Add resume support for Native Instruments controls] brought a regression where the Native Instrument audio devices don't get the correct value at update due to the missing shift at writing. This patch addresses it.

* ALSA: usb-audio: Add a more accurate volume quirk for AudioQuest DragonFlyAnssi Hannula2015-12-141-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AudioQuest DragonFly DAC reports a volume control range of 0..50 (0x0000..0x0032) which in USB Audio means a range of 0 .. 0.2dB, which is obviously incorrect and would cause software using the dB information in e.g. volume sliders to have a massive volume difference in 100..102% range. Commit 2d1cb7f658fb ("ALSA: usb-audio: add dB range mapping for some devices") added a dB range mapping for it with range 0..50 dB. However, the actual volume mapping seems to be neither linear volume nor linear dB scale, but instead quite close to the cubic mapping e.g. alsamixer uses, with a range of approx. -53...0 dB. Replace the previous quirk with a custom dB mapping based on some basic output measurements, using a 10-item range TLV (which will still fit in alsa-lib MAX_TLV_RANGE_SIZE). Tested on AudioQuest DragonFly HW v1.2. The quirk is only applied if the range is 0..50, so if this gets fixed/changed in later HW revisions it will no longer be applied. v2: incorporated Takashi Iwai's suggestion for the quirk application method Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: usb-audio: harmless underflow in snd_audigy2nx_led_put()Dan Carpenter2015-09-281-1/+1
| | | | | | | | | | We want to verify that "value" is either zero or one, so we test if it is greater than one. Unfortunately, this is a signed int so it could also be negative. I think this is harmless but it introduces a static checker warning. Let's make "value" unsigned. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: usb-audio: Avoid nested autoresume callsTakashi Iwai2015-08-261-72/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the recent fix of runtime PM for USB-audio driver, we got a lockdep warning like: ============================================= [ INFO: possible recursive locking detected ] 4.2.0-rc8+ #61 Not tainted --------------------------------------------- pulseaudio/980 is trying to acquire lock: (&chip->shutdown_rwsem){.+.+.+}, at: [<ffffffffa0355dac>] snd_usb_autoresume+0x1d/0x52 [snd_usb_audio] but task is already holding lock: (&chip->shutdown_rwsem){.+.+.+}, at: [<ffffffffa0355dac>] snd_usb_autoresume+0x1d/0x52 [snd_usb_audio] This comes from snd_usb_autoresume() invoking down_read() and it's used in a nested way. Although it's basically safe, per se (as these are read locks), it's better to reduce such spurious warnings. The read lock is needed to guarantee the execution of "shutdown" (cleanup at disconnection) task after all concurrent tasks are finished. This can be implemented in another better way. Also, the current check of chip->in_pm isn't good enough for protecting the racy execution of multiple auto-resumes. This patch rewrites the logic of snd_usb_autoresume() & co; namely, - The recursive call of autopm is avoided by the new refcount, chip->active. The chip->in_pm flag is removed accordingly. - Instead of rwsem, another refcount, chip->usage_count, is introduced for tracking the period to delay the shutdown procedure. At the last clear of this refcount, wake_up() to the shutdown waiter is called. - The shutdown flag is replaced with shutdown atomic count; this is for reducing the lock. - Two new helpers are introduced to simplify the management of these refcounts; snd_usb_lock_shutdown() increases the usage_count, checks the shutdown state, and does autoresume. snd_usb_unlock_shutdown() does the opposite. Most of mixer and other codes just need this, and simply returns an error if it receives an error from lock.

* ALSA: usb-audio: Allow quirks to handle own resume and proc dumpTakashi Iwai2014-11-211-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | So far, we blindly assumed that the all usb-audio mixer elements follow the standard and apply the standard resume method for the registered elements in the id_elems[] list. However, some quirks really need the own resume and it's incomplete for now. This patch enhances the resume handling in two folds: - split some fields in struct usb_mixer_elem_info into a smaller header struct (usb_mixer_elem_list) for keeping the minimal information in the linked-list; the usb_mixer_elem_info embeds this header struct instead - add resume and dump callbacks to usb_mixer_elem_list struct to allow quirks providing the own methods For the standard mixer elements, these new callbacks are set to the standard ones as default, thus there is no functional change by this patch yet. The dump and resume callbacks are typedef'ed for ease of later patches using arrays of such function pointers. Signed-off-by: Takashi Iwai <tiwai@suse.de>

* | ALSA: usb-audio: Scarlett mixer interface for 6i6, 18i6, 18i8 and 18i20Chris J Arges2014-11-131-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code contains the Scarlett mixer interface code that was originally written by Tobias Hoffman and Robin Gareus. Because the device doesn't properly implement UAC2 this code adds a mixer quirk for the device. Changes from the original code include removing the metering code along with dead code and comments. Compiler warnings were fixed. The code to initialize the sampling rate was causing a crash this was fixed as discussed on the mailing list. Error, and info messages were convered to dev_err and dev_info interfaces. The custom scarlett_mixer_elem_info struct was replaced with the more generic usb_mixer_elem_info to be able to recycle more code from mixer.c. This patch also makes additional modifications based on upstream comments. Individual control creation functions are removed and a generic function is no used. Macros for function calls are removed to improve readability. Hardcoded control initialization is removed. Save to HW functionality has been removed. Strings for enums are created dynamically for the mixer. Strings used for controls are now SNDRV_CTL_ELEM_ID_NAME_MAXLEN length.

| | | | | | | | | | This was a flaw in the reading of the spec tables - Native Instrument's "Komplete Audio 6" device has no such extra controls. This patch also fixes the device name in two comments. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | This new device by Native Instruments is also compliant to the USB standard v2.0, but hides this detail at when connected. It needs the same boot quirks than other models, and also has two non-class-compliant mixer controls. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: usb-audio: add support for Native Instruments MK2 devicesDaniel Mack2011-02-141-0/+153
| | | | | | | | | | | | | | | | | | The MK2 generation of Native Instruments' sound cards are in fact compliant to the USB audio standard of version 2 and other approved USB standards. However, they come up as vendor-specific device when first connected but can be told to come up with a new set of descriptors upon their next enumeration. The interfaces announced by the new descriptors will be handled by the kernel's class drivers. This is done by issuing a vendor specific device request and sending the device to reset. There are also some vendor-specific USB requests for some mixer elements that can't be exported in a standard compliant way. The driver now supports them with quirks handling mechanisms.
