* ALSA: compress: Pass through return value of open ops callbackCharles Keepax2014-03-191-1/+1
| | | | | | | | | | | | | | | | The snd_compr_open function would always return 0 even if the compressed ops open function failed, obviously this is incorrect. Looks like this was introduced by a small typo in: commit a0830dbd4e42b38aefdf3fb61ba5019a1a99ea85 ALSA: Add a reference counter to card instance This patch returns the value from the compressed op as it should.

| * ALSA: Add helper function for intersecting two rate masksLars-Peter Clausen2014-01-141-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A bit of special care is necessary when creating the intersection of two rate masks. This comes from the special meaning of the SNDRV_PCM_RATE_CONTINUOUS and SNDRV_PCM_RATE_KNOT bits, which needs special handling when intersecting two rate masks. SNDRV_PCM_RATE_CONTINUOUS means the hardware supports all rates in a specific interval. SNDRV_PCM_RATE_KNOT means the hardware supports a set of discrete rates specified by a list constraint. For all other cases the supported rates are specified directly in the rate mask.

* | ALSA: PCM: Warn when buffer preallocation failsTakashi Iwai2014-01-111-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | The failures of buffer preallocations at driver initializations aren't critical but it's still helpful to inform, so that user can know that something doesn't work as expected. For example, the recent page allocator change triggered regressions, but developers didn't notice until recently because the driver didn't complain. Signed-off-by: Takashi Iwai <tiwai@suse.de>

It was rarely useful (only for preserving pages among module reloading or a little help by an early boot scripting), used only by a couple of drivers, and yet it gives too much ugliness than its benefit.

| * ALSA: jack: Unregister input device at disconnectionTakashi Iwai2013-11-141-3/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent change in sysfs triggered a kernel WARNING at unloading a sound driver like WARNING: CPU: 3 PID: 2247 at fs/sysfs/group.c:214 sysfs_remove_group+0xe8/0xf0() sysfs group ffffffff81ab7b20 not found for kobject 'event14' for each jack instance. It's because the unregistration of jack input device is done in dev_free callback, which is called after snd_card_disconnect(). Since device_unregister(card->card_dev) is called in snd_card_disconnect(), the whole sysfs entries belonging to card->card_dev have been already removed recursively. Thus this results in a warning as input_unregister_device() yet tries to unregister the already removed sysfs entry. For fixing this mess, we need to unregister the jack input device at dev_disconnect callback so that it's called before unregistering the card->card_dev.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Pausing audio playback is not an illegal state so it doesn't seem sensible for poll() to return -EBADFD on a paused stream. There's also no reason to assume that we can't write more data to the DSP while playback is paused. Remove the -EBADFD so that a stream in paused state will still report the buffer availability from poll(). It is up to the user process to manage its state so that it knows whether it is paused or not.

Thus we make the drain and partial_drain callback as non blocking and driver returns immediately after notifying DSP. The waiting is done while releasing the lock so that other ops can go ahead.

This is triggered only by special --install stuff Debian is using, but it's still not good to have such loops. As a workaround, call the registration part asynchronously.

| | | | | | | | | | | | | | | | | | | | The commit [1ca2f2ec: ALSA: vmaster: Add snd_ctl_sync_vmaster() helper function] changed master_put() function and the check for the required vmaster hook call is wrongly performed now, which results in the missing hook call upon "Master Playback Switch" value changes.

| | | | | | | | | | | | | | | | | | | | | | | | Introduce a new helper function, snd_ctl_sync_vmaster(), which updates the slave put callbacks forcibly as well as calling the hook. This will be used in the upcoming patch in HD-audio codec driver for toggling the mute in vmaster slaves. Along with the new function, the old snd_ctl_sync_vmaster_hook() is replaced as a macro calling with the argument hook_only=true. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| * | ALSA: Add kconfig to specify the max card numbersTakashi Iwai2013-05-242-9/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently ALSA supports up to 32 card instances when the dynamic minor is used. While 32 cards are usually big enough for normal use cases, there are sometimes weird requirements with more card support. Actually, this limitation, 32, comes from the index option, where you can pass the bit mask to assign the card. Other than that, we can actually give more cards up to the minor number limits (currently 256, which can be extended more, too). This patch adds a new Kconfig to specify the max card numbers, and changes a few places to accept more than 32 cards. The only incompatibility with high card numbers would be the handling of index option. The index option can be still used to pass the bitmask for card assignments, but this works only up to 32 slots. More than 32, no bitmask style option is available but only a single slot can be specified via index option. Signed-off-by: Takashi Iwai <tiwai@suse.de>
| * | ALSA: Fix the default suffix string with high card numberTakashi Iwai2013-05-241-17/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ALSA core tries to add a suffix as "_1" automatically when the given id string conflicts. The current code assumes implicitly that the max card number is 16 so that the single hex "_X" suffix can be put. However, with the dynamic device management, the card can be at most 32, so it can put even a non-hex character there. Also, when the max card number is increased in future, this would result in worse. This patch rewrites the code to add the suffix string in a simpler (thus cleaner) way. It can support up to three digits, so it should suffice for most requirements. Signed-off-by: Takashi Iwai <tiwai@suse.de>
