2013-12-17ALSA: Add SNDRV_PCM_STATE_PAUSED case in wait_for_avail functionJongHo Kim1-0/+2
When the process is sleeping at the SNDRV_PCM_STATE_PAUSED state from the wait_for_avail function, the sleep process will be woken by timeout(10 seconds). Even if the sleep process wake up by timeout, by this patch, the process will continue with sleep and wait for the other state.

2013-11-14ALSA: jack: Unregister input device at disconnectionTakashi Iwai1-3/+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.

2013-11-12ALSA: compress_core: don't return -EBADFD from poll if pausedRichard Fitzgerald1-2/+1
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.

2013-11-07ALSA: compress: fix drain calls blocking other compress functions (v6)Vinod Koul1-12/+19
The drain and drain_notify callback were blocked by low level driver until the draining was complete. Due to this being invoked with big fat mutex held, others ops like reading timestamp, calling pause, drop were blocked. So to fix this we add a new snd_compr_drain_notify() API. This would be required to be invoked by low level driver when drain or partial drain has been completed by the DSP. 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.

2013-05-24ALSA: Add kconfig to specify the max card numbersTakashi Iwai2-9/+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>
2013-05-24ALSA: Fix the default suffix string with high card numberTakashi Iwai1-17/+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>

A significant change in the subsystem level is the introduction of snd_soc_component, which will help more generic handling of SoC and off-SoC components.

2013-05-01proc: Supply a function to remove a proc entry by PDEDavid Howells1-14/+5
Supply a function (proc_remove()) to remove a proc entry (and any subtree rooted there) by proc_dir_entry pointer rather than by name and (optionally) root dir entry pointer. This allows us to eliminate all remaining pde->name accesses outside of procfs.

2013-04-22ALSA: compress: Use kzalloc() for ioctls writing back dataTakashi Iwai1-2/+2
Like the previous patch by Dan, we should clear the data to be returned from certain compress ioctls, namely, snd_compr_get_codec_caps() and snd_compr_get_params(). This time, we can simply replace kmalloc() with kzalloc(). Signed-off-by: Takashi Iwai <tiwai@suse.de>
