2013-10-24ALSA: hda - hdmi: Allow HDA patches to customize more operationsAnssi Hannula
Upcoming AMD multichannel support requires many customized operations (channel mapping, ELD, HBR) but can otherwise share most of its code with the generic patch. Add a local struct hdmi_ops containing customizable HDMI-specific callbacks and move the current code to those callbacks. Functionality is unaltered.

2013-10-24ALSA: hda/realtek - Raise the delay for alc283_shutupKailang Yang

2013-10-24ALSA: compress: fix drain calls blocking other compress functionsVinod Koul
The drain and drain_notify callback were blocked by low level driver untill 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 relasing the lock so that other ops can go ahead.

2013-10-24ALSA: Add ifdef CONFIG_GENERIC_ALLOCATOR for SNDRV_DMA_TYPE_IRAM codeTakashi Iwai
It turned out that we can't use gen_pool_*() functions on archs without CONFIG_GENERIC_ALLOCATOR (resulting in missing symbols), since linux/genalloc.h doesn't provide dummy functions for all. We'd be able to fix linux/genalloc.h size, but I take an easier path for now... Reported-by: Fengguang Wu <fengguang.wu@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-10-24ALSA: hda - Fix mute LED on HP laptops in runtime suspendTakashi Iwai
When HP laptops with mute and mic-record LEDs go to runtime suspend, these LEDs are turned on forcibly no matter whether GPIO pis are on or off. This strange behavior seems triggered by resetting the HD-audio bus link at azx_rutime_suspend(). So, just add a new hda_bus flag to avoid the link reset at runtime suspend and set it for these HP machines. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2013-10-24ALSA: hda - Remove OOM message after input_allocate_deviceJoe Perches

2013-10-24ALSA: Add SoC on-chip internal ram support for DMA buffer allocationNicolin Chen
Now it's quite common that an SoC contains its on-chip internal RAM. By using this RAM space for DMA buffer during audio playback/record, we can shutdown the voltage for external RAM to save power. So add new DEV type with iram malloc()/free() and accordingly modify current default mmap() for the iram circumstance.

2013-10-20ALSA: dice: restrict the driver to playback-only devicesClemens Ladisch
At the moment, this driver supports only playback, while FFADO supports (only) full-duplex devices. So, prevent conflicts by not claiming devices that would be better handled by FFADO. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2013-10-20ALSA: dice: document quadlet alignmentClemens Ladisch
Doing accesses without quadlet alignment is a bad idea because the firmware's byte-swapping would garble the data; clarify this in the documentation. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2013-10-20ALSA: dice: remove 10s period length limitClemens Ladisch

2013-10-20ALSA: dice: avoid superflous write at bus resetClemens Ladisch
When a bus reset happens, the enable register is automatically cleared, so we do not need to clear it manually when stopping the stream. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-20ALSA: firewire: extend snd_fw_transaction()Clemens Ladisch
Add a flag to snd_fw_transaction() to allow it to abort when a bus reset happens. This removes most of the duplicated error handling loops that were required around calls to the low-level fw_run_transaction(). Also add a flag to suppress error messages; errors are expected when we attempt to clean up after the device was unplugged. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2013-10-20ALSA: dice: fix device detection for other vendorsClemens Ladisch
DICE devices do not have a unique specifier ID in their unit directory (it's always the same as the device vendor's ID), so rely on just the version ID for driver loading, and use a heuristic in the probe callback to detect actual DICE devices. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2013-10-20ALSA: firewire: introduce amdtp_out_stream_running()Clemens Ladisch

2013-10-20ALSA: dice: fix hang when unplugging a running deviceClemens Ladisch
When aborting a PCM stream, the xrun is signaled only if the stream is running. When disconnecting a PCM stream, calling snd_card_disconnect() too early would change the stream into a non-running state and thus prevent the xrun from being noticed by user space. To prevent this, move the snd_card_disconnect() call after the xrun. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-20ALSA: dice, firewire-lib: add blocking modeClemens Ladisch
Allow AMDTP output streams to use blocking mode. Use it for DICE devices, because the old DICE-II chip will in some cases not be able to lock to non-blocking streams (erratum E7). Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2013-10-20ALSA: dice: allow all sample ratesClemens Ladisch
Instead of forcing a constant 44.1 kHz, read the current sample rate from the device when opening the PCM device. Actually changing the sample rate requires some separate controller application. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-20ALSA: dice: optimize bus reset handlingClemens Ladisch

Partially restructures _snd_emu10k1_audigy_init_efx() and _snd_emu10k1_init_efx() functions. Be noted that the cast is demanded to use '__user'.

2013-10-17ALSA: add DICE driverClemens Ladisch
As a start point for further development, this is an incomplete driver for DICE devices: - only playback (so no clock source except the bus clock) - only 44.1 kHz - no MIDI - recovery after bus reset is slow - hwdep device is created, but not actually implemented Contains compilation fixes by Stefan Richter.

2013-10-17ALSA: hda - Move mutex from hda_eld to per_pin in HDMI codec driverTakashi Iwai
Since the lock is used primarily in patch_hdmi.c, it's better to move it in the local struct instead of exporting in hda_eld. The only functions requiring the lock in hda_eld.c are proc accessors. So in this patch, the proc entry and its creation/deletion/accessors are moved into patch_hdmi.c, together with the mutex lock to pin_spec struct. The former proc info functions are exported so that they can be called from patch_hdmi.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-10-17ALSA: hda - Fix possible races in HDMI driverTakashi Iwai
Some per_pin fields and ELD contents might be changed dynamically in multiple ways where the concurrent accesses are still opened in the current code.

2013-10-17ALSA: hda - Treat zero connection as non-errorTakashi Iwai
The zero-length connection list happens so often on Haswell HDMI, and it results in warning messages like ALSA: hda_codec: invalid CONNECT_LIST verb 5[1]:0 at each time the codec resumes from the power-save, which is fairly annoying. Since this is no real error, make it shown only in the verbose debug mode. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2013-10-10ALSA: hda - Enable surround speakers (when line out is also present)David Henningsson
In the case where we have both line out and more than stereo speakers, the speaker DACs will end up in extra_out_nid. In fact, AFAIU, speakers are the only ones that can end up in extra_out_nid, and if we have several of those, they should be surround outputs rather than copy front.
