2014-06-04ALSA: fireworks: Remove meaningless mutex_destroy()Takashi Sakamoto
Currently mutex_destroy() is called in module's cleanup function. But after cleaned up, this mutex is automatically released. So this function call is meaningless.

2014-06-02ALSA: firewire-lib: Use IEC 61883-6 compliant labels for Raw Audio dataTakashi Sakamoto
According to AM824 in IEC 61883-6:2002, 2 bits in LSB of label for Raw Audio data means Valid Length Code (VBL). Ths value is: - b00 for 24 bits sample (label is 0x40) - b01 for 20 bits sample (label is 0x41) - b10 for 16 bits sample (label is 0x42) But current firewire-lib apply 24 bits label for both of 16/24 bits samples. As long as developers investigate BeBoB/Fireworks/OXFW/Dice, all of them have a behaviour to ignore the label. They can generate correct sound even if firewire-lib gives wrong label (i.e. 0xff). On BeBoB, this is not only for Raw Audio data channel, but also for IEC 60958 Conformant data channel. So there is little possibility of regression.

Now snd-firewire-lib supports rawmidi in addition to PCM, thus we need to give a proper dependency. For fixing and simplification, move the selections of SND_PCM and SND_RAWMIDI into SND_FIREWIRE_LIB section. Then each driver doesn't have to select them but only SND_FIREWIRE_LIB.

2014-05-27ALSA: fireworks/bebob: Use the same type of variables as function parametersTakashi Sakamoto
The second argument of snd_efw_command_get_sampling_rate() means sampling rate and its type is 'unsigned int'. But 'int' variable is passed as parameter. It's better to apply the same type for the variable as its argument.

2014-05-26ALSA: firewire/bebob: Add a workaround for M-Audio special Firewire seriesTakashi Sakamoto
In post commit, a quirk of this firmware about transactions is reported. This commit apply a workaround for this quirk. They often fail transactions due to gap_count mismatch. This state is changed by generating bus reset. The fw_schedule_bus_reset() is an exported symbol in firewire-core. But there are no header for public. This commit moves its prototype from drivers/firewire/core.h to include/linux/firewire.h. This mismatch still affects bus management before generating this bus reset.

2014-05-26ALSA: bebob: Add support for M-Audio special Firewire seriesTakashi Sakamoto
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. The usual operations can't be applied to them. For this reason, this commit adds a model specific member to 'struct snd_bebob' and some model specific functions. 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 module don't support to upload firmware.

2014-05-26ALSA: bebob: Add support for M-Audio usual Firewire seriesTakashi Sakamoto
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>

2014-05-26ALSA: bebob/firewire-lib: Add a quirk for discontinuity at bus resetTakashi Sakamoto
Normal BeBoB firmware has a quirk. When receiving bus reset, it transmits packets with discontinuous value in dbc field. This causes two situation, one is to abort streaming by firewire-lib as a result of detecting the discontinuity. Another is to call driver's .update() because of bus reset. These two is generated independently. (The former depends on isochronous stream and the latter depends on IEEE1394 bus driver.) When BeBoB driver works with XRUN-recoverable applications, this situation looks like stream_start_duplex() call followed by stream_update_duplex() call because applications will call snd_pcm_prepare() immediately at XRUN. To update connections and streams at first, this commit use completion. When queueing error occurs, stream_start_duplex() is forced to wait maximum 1000msec. During this, when .update() is called, the completion is waken and stream_start_duplex() is processed without breaking connections. At bus reset, stream_start_duplex() shouldn't break/establish connections and stream_update_duplex() should update connections because a caller of fw_iso_resources_allocate() is responsible for calling fw_iso_resources_update() on bus reset. This commit also adds a flag, which has an effect to skip checking continuity for first packet. This flag is useful for BeBoB quirk to start handling packets during streaming.

2014-05-26ALSA: fireworks: Add command/response functionality into hwdep interfaceTakashi Sakamoto
This commit adds two functionality for hwdep interface, adds two parameters for this driver, add a node for proc interface. To receive responses from devices, this driver already allocate own callback into initial memory space in host controller. This means no one can allocate its own callback to the address. So this driver must give a way for user applications to receive responses. This commit adds a functionality to receive responses via hwdep interface. The application can receive responses to read from this interface. To achieve this, this commit adds a buffer to queue responses. The default size of this buffer is 1024 bytes. This size can be changed to give preferrable size to 'resp_buf_size' parameter for this driver. The application should notice rest of space in this buffer because this driver don't push responses when this buffer has no space. Additionaly, this commit adds a functionality to transmit commands via hwdep interface. The application can transmit commands to write into this interface. I note that the application can transmit one command at once, but can receive as many responses as possible untill the user-buffer is full. When using these interfaces, the application must keep maximum number of sequence number in command within the number in firewire.h because this driver uses this number to distinguish the response is against the command by the application or this driver. Usually responses against commands which the application transmits are pushed into this buffer. But to enable 'resp_buf_debug' parameter for this driver, all responses are pushed into the buffer. When using this mode, I reccomend to expand the size of buffer. Finally this commit adds a new node into proc interface to output status of the buffer.

2014-05-26ALSA: fireworks/firewire-lib: Add a quirk for fixed interval of reported dbcTakashi Sakamoto
Fireworks firmware version 5.5 reports fix interval for dbc in each packet. For example, AudioFire4: CIP0 CIP1 Payload 00070000 900484FF 72 00070008 9004A8FF 72 00070008 90FFFFFF 02 00070010 9004D0FF 72 00070018 9004C4FF 72 00070020 9004E8FF 72 00070020 90FFFFFF 02 00070028 900410FE 72 The interval of each dbc should be 16 except for empty packet but it's still 8. This commit adds a flag for this quirk and codes to refer to a fixed value. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
