2013-10-22Merge branch 'dice-driver-playback-only' of ↵Takashi Iwai13-150/+2137
git://git.alsa-project.org/alsa-kprivate into for-next
2013-10-21ALSA: dice: restrict the driver to playback-only devicesClemens Ladisch2-4/+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>
2013-10-21ALSA: dice: fix detection of Weiss devicesClemens Ladisch1-5/+12
While most DICE devices keep TCAT's default category ID of 0x04, Weiss devices identify themselves with 0x00. Reported-by: Rolf Anderegg <rolf.anderegg@weiss.ch> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: dice_proc_read: remove wrong typecastClemens Ladisch1-2/+1
Remove a wrong typecast that resulted from a copy-and-paste error. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: document quadlet alignmentClemens Ladisch1-3/+3
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>
2013-10-21ALSA: dice: add a proc file to show device informationClemens Ladisch1-0/+246
For easier debugging, add a proc file to show the device's capabilities and current status. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: check clock change timeoutClemens Ladisch1-2/+3
Output a warning if the wait for the clock change notification times out. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: dynamic sample rate selectionClemens Ladisch1-35/+102
Instead of relying of some control panel application to configure some fixed sample rate, allow applications to set it automatically. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: get rate-dependent parametersClemens Ladisch1-2/+90
In preparation for sample rate selection support, read the stream parameters that might change when running at different sample rates. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: allow notifications during initializationClemens Ladisch1-11/+11
Reorganize the initialization order so that the driver can receive notifications earlier. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: get clock capabilitiesClemens Ladisch1-2/+21
In preparation for sample rate selection support, ensure that the driver knows about the device's clock capabilities. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2013-10-21ALSA: dice: fix lockingStefan Richter1-4/+4
Avoid a lock inversion between dice->mutex and pcm->open_mutex. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: remove superfluous fieldClemens Ladisch1-3/+1
The pcm field was not actually used. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: remove 10s period length limitClemens Ladisch1-1/+1
Since commit f2b3614cefb6 (Don't check DMA time-out too shortly), we need no longer to restrict the period length to less than 10 s. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: avoid superflous write at bus resetClemens Ladisch1-0/+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>
2013-10-21ALSA: firewire: extend snd_fw_transaction()Clemens Ladisch8-206/+137
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>
2013-10-21ALSA: dice: optimize reading of consecutive registersClemens Ladisch1-16/+11
Instead of reading two consecutive register with two quadlet requests, use one block read request. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: support dual-wire stream format at 192 kHzClemens Ladisch4-67/+164
Change the AMDTP streaming code to handle the non-standard stream format that DICE devices use at sample rates greater than 96 kHz. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: fix device detection for other vendorsClemens Ladisch1-18/+84
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>
2013-10-21ALSA: dice: reorganize interface definitionsClemens Ladisch2-207/+373
Move the DICE interface symbols into a separate header file, and add more documentation. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: firewire: introduce amdtp_out_stream_running()Clemens Ladisch4-23/+18
Introduce the helper function amdtp_out_stream_running(). This makes many checks in amdtp.c clearer and frees the device drivers from having to track this with a separate variable. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: clear device lock when closing hwdep deviceClemens Ladisch1-0/+13
Ensure that misbehaving or aborted userspace programs do not accidentally keep the lock. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: implement hwdep deviceClemens Ladisch1-22/+203
Implement the hwdep locking and notification mechanisms. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: fix hang when unplugging a running deviceClemens Ladisch1-2/+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>
2013-10-21ALSA: dice, firewire-lib: add blocking modeClemens Ladisch3-27/+36
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>
2013-10-21ALSA: dice: reduce noisy loggingClemens Ladisch1-2/+2
The notification bits are not of general interest; log them only when debugging. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-21ALSA: dice: allow all sample ratesClemens Ladisch1-13/+42
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>
2013-10-21ALSA: dice: optimize bus reset handlingClemens Ladisch1-55/+93
After a bus reset, do not stop the stream completely to avoid having to reconfigure the device when restarting the stream. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2013-10-17ALSA: add DICE driverClemens Ladisch3-0/+1023
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. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>

2013-06-09firewire: introduce fw_driver.probe and .remove methodsStefan Richter3-107/+82
FireWire upper layer drivers are converted from generic struct driver.probe() and .remove() to bus-specific struct fw_driver.probe() and .remove(). The new .probe() adds a const struct ieee1394_device_id *id argument, indicating the entry in the driver's device identifiers table which matched the fw_unit to be probed. This new argument is used by the snd-firewire-speakers driver to look up device-specific parameters and methods. There is at least one other FireWire audio driver currently in development in which this will be useful too. The new .remove() drops the unused error return code. Although all in-tree drivers are being converted to the new methods, support for the old methods is left in place in this commit. This allows public developer trees to merge this commit and then move to the new fw_driver methods.

2012-05-14ALSA: firewire-lib: optimize packet flushingClemens Ladisch2-1/+8
Trying to flush completed packets is pointless when the pointer callback was called from the packet completion callback; avoid it. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-05-14ALSA: firewire-lib: flush completed packets when reading PCM positionClemens Ladisch2-12/+15

2012-05-14ALSA: firewire-lib: taskletize the snd_pcm_period_elapsed() callClemens Ladisch2-13/+31
The following patch might introduce this call chain: PCM .pointer callback + fw_iso_context_flush_completions + packet callback + snd_pcm_period_elapsed + PCM .pointer callback Recursive calls to the pointer callback are not possible due to the PCM group locking, so avoid this by moving the period notification into a separate tasklet.

2012-01-15firewire: move fw_device reference counting from drivers to coreStefan Richter2-7/+1
fw_unit device drivers invariably need to talk to the fw_unit's parent (an fw_device) and grandparent (an fw_card). firewire-core already maintains an fw_card reference for the entire lifetime of an fw_device. Likewise, let firewire-core maintain an fw_device reference for the entire lifetime of an fw_unit so that fw_unit drivers don't have to. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
