2016-11-18ALSA: bebob: compare whole string for model name so that readers are not ↵Takashi Sakamoto1-2/+2
confused A modalias of 'ieee1394:ven00000D6Cmo00010060sp' hits units for M-Audio FireWire Audiophile only. However the unit has two states relevant to loaded firmware. Initial firmware returns 'FW Audiophile Bootloader', while functional firmware returns 'FW Audiophile'. ALSA bebob driver compares the units' model name to strings of 24 characters by the first 15 characters. This is shorter way to differentiate these two states but confusing to readers. This commit improves the code for this point. Kernel stack is consumed more in call of check_audiophile_booted() by a bit.

2016-02-20ALSA: bebob: give up updating streams at bus reset handlerTakashi Sakamoto1-4/+16
DM1000/DM1100/DM1500 chipsets transfer packets with discontinue value in 'dbc' field of CIP header. For ALSA bebob driver, this makes its bus-reset handler meaningless, because the discontinuity is detected quite earlier than executing the handler. This commit gives up updating streams at the bus reset handler. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2016-02-20ALSA: bebob: simplify bus-reset handlingTakashi Sakamoto1-4/+3
At bus-reset, DM1000/DM1100/DM1500 chipsets transfer packets with discontinuous value in 'dbc' field of CIP header. In this case, packet streaming layer in firewire-lib module stops streaming and set XRUN to PCM substream. In ALSA, PCM applications are notified the XRUN status by the return value of ALSA PCM interface. They can recover this state by executing snd_pcm_prepare(), then PCM drivers' prepare handler is called, and start new PCM substream. For ALSA BeBoB driver, the handler establishes new connections and start new AMDTP streaming. Unfortunately, neither the PCM applications nor the driver know the reason of XRUN. The driver gets to know the reason when update handler is called by IEEE 1394 bus driver. As long as I tested, the order of below events are not fixed: * Detecting packet discontinuity in tasklet context of OHCI 1394 driver * Calling prepare handler in process context of ALSA PCM application * Calling update handler in kthread context of IEEE 1394 bus driver The unpredictable order is disadvantage for the driver to be compliant to CMP. In IEC 61883-1, new CMP establish operations should be done 1 sec (isoc_resource_delay) after bus-reset. Within 1 sec, CMP restore operations are allowed. For this reason, in former commit ('b6bc812327aa: ALSA: bebob/firewire-lib: Add a quirk for discontinuity at bus reset'), the process context is forced to wait for executing update handler. The process context wait for bus-reset up to 1 sec. This commit solves the issue, while causes more disadvantages. For PCM applications, calling snd_pcm_prepare() for recovering XRUN state takes more time and the driver got a bit complicated code, while the recovery is not always successful. As long as I tested, DM1000/DM1100/DM1500 and BeBoB firmware can allow drivers to establish new connections just after bus reset. Furthermore, any FCP transactions are handled correctly. Therefore, the driver don't need to wait for bus reset handler for starting new streaming. This commit removes the codes to reduce maintenance cost.

This commit allows this driver to support some models which M-Audio produces with DM1000 but its firmware is special. They are: - Firewire 1814 - ProjectMix I/O They have heavily customized firmware.

Some parameters are write-only so this commit also adds control interface for applications to set them. M-Audio special firmware quirks: - Just after powering on, they wait to download firmware. This state is changed when receiving cue. Then bus reset is generated and the device is recognized as a different model with the uploaded firmware. - They don't respond against BridgeCo AV/C extension commands. So drivers can't get their stream formations and so on. - They do not start to transmit packets only by establishing connection but also by receiving SIGNAL FORMAT command. - After booting up, they often fail to send response against driver's request due to mismatch of gap_count.

This commit allows this driver to support some models which M-Audio produces with DM1000/DM1000E with usual firmware. They are: - Firewire 410 - Firewire AudioPhile - Firewire Solo - Ozonic - NRV10 - FirewireLightBridge According to a person who worked in BridgeCo, some models are produced with 'Pre-BeBoB'. This means that these products were released before BeBoB was officially produced, and later BeBoB specification was formed. So these models have some quirks. M-Audio usual firmware quirks: - Just after powering on, 'Firewire 410' waits to download firmware. This state is changed when receiving cue. Then bus reset is generated and the device is recognized as a different model with the uploaded firmware. - 'Firewire Audiophile' also waits to download firmware but its vendor id/model id is the same as the one after loading firmware. - The information of channel mapping for MIDI conformant data channel is invalid against BridgeCo specification. This commit adds some codes for these quirks but don't support to upload firmware. This commit also adds specific operations to get metering information. The metering information also includes status of clock synchronization if the model supports to switch source of clock. The specification of FirewireLightBridge is unknown. So in this time, normal operations are applied for this model. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

Then this commit adds functionality related to stream such as sampling frequency or clock source. For help to debug, this commit adds the functionality to get metering information if it's available. To help these functionalities, this commit adds some AV/C commands defined in 'AV/C Audio Subunit Specification (1394TA).

2014-05-26ALSA: bebob: Add PCM interfaceTakashi Sakamoto1-0/+4
This commit adds a functionality to capture/playback PCM samples. When AMDTP stream is already running for PCM or the source of clock is not internal, available sampling rate is limited at current one.

2014-05-26ALSA: bebob: Add MIDI interfaceTakashi Sakamoto1-0/+7
This commit adds a functionality to capture/playback MIDI messages. When no AMDTP streams are running, this module starts AMDTP stream at current sampling rate for MIDI substream. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-05-26ALSA: bebob: Add proc interface for debugging purposeTakashi Sakamoto1-0/+2
This commit adds proc interface to get these information for debugging: - firmware information - stream formation - current clock source and sampling rate Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2014-05-26ALSA: bebob: Add commands and connections/streams managementTakashi Sakamoto1-1/+14
This commit adds management functionality for connections and streams. BeBoB uses CMP to manage connections and uses AMDTP for streams. This commit also adds some BridgeCo's AV/C extension commands. There are some BridgeCo's AV/C extension commands but this commit just uses below commands to get device's capability and status: 1.Extended Plug Info commands - Plug Channel Position Specific Data - Plug Type Specific Data - Cluster(Section) Info Specific Data - Plug Input Specific Data 2.Extended Stream Format Information commands - Extended Stream Format Information Command - List Request For Extended Plug Info commands for Cluster Info Specific Data, I pick up 'section' instead of 'cluster' from document to prevent from misunderstanding because 'cluster' is also used in IEC 61883-6.

2014-05-26ALSA: bebob: Add skelton for BeBoB based devicesTakashi Sakamoto1-0/+292
This commit adds a new driver for BeBoB based devices with no specific operations. Currently this driver just create/remove card instance according to callbacks. BeBoB is 'BridgeCo enhanced Breakout Box'. This is installed to firewire devices with DM1000/DM1100/DM1500 chipset. It gives common way for host system to handle BeBoB based devices.
