* ALSA: Add SoC on-chip internal ram support for DMA buffer allocationNicolin Chen2013-10-243-0/+59
| | | | | | | | | | | | | 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.

| * ALSA: dice: restrict the driver to playback-only devicesClemens Ladisch2013-10-202-4/+15
| | | | | | | | | | | | | | | | 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>

| * ALSA: dice: avoid superflous write at bus resetClemens Ladisch2013-10-201-0/+5
| | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | 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.

| * ALSA: dice: fix hang when unplugging a running deviceClemens Ladisch2013-10-201-2/+5
| | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | ALSA: hda - Move mutex from hda_eld to per_pin in HDMI codec driverTakashi Iwai2013-10-173-81/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently hdmi_setup_audio_infoframe() reprograms the HDA channel mapping only when the infoframe is not up-to-date or the non-PCM flag has changed. However, when just the channel map has been changed, the infoframe may still be up-to-date and non-PCM flag may not have changed, so the new channel map is not actually programmed into the HDA codec. Notably, this failing case is also always triggered when the device is already in a prepared state and a new channel map is configured while changing only the channel positions (for example, plain "speaker-test -c2 -m FR,FL"). Fix that by always programming the channel map in hdmi_setup_audio_infoframe(). Tested on Intel HDMI.
