Currently mutex_unlock() is called in module's cleanup function. But after cleaned up, this mutex is automatically released. So this function call is meaningless. Signed-off-by:

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. Similally, the type of variable for snd_efw_command_get_clock_source() and avc_bridgeco_get_plug_type() should be the same type as each argument. Signed-off-by:

Originally, I intent to this argument given with 'struct snd_pcm_runtime.rate' or params_rate(). They return value of 'unsigned int'. So 'unsigned int' is better for the type of this argument. Signed-off-by:

There are two modes for Fireworks, IEC 61883 compliant or Windows. So it's better to use enum type instead of int to express the intension, even if C language specification defines to handle enum variables as usual integer. Signed-off-by:

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. It still takes a time to call driver's probe() because transactions are still often failed. Signed-off-by:

Just powering on, these devices below wait to download firmware. - Firewire Audiophile - Firewire 410 - Firewire 1814 - ProjectMix I/O But firmware version 5058 or later, flash memory in the device stores the firmware. So this driver can enable these devices by sending a certain cue to load the firmware. Signed-off-by:

ALSA: bebob/firewire-lib: Add a quirk of wrong dbc in empty packet for M-Audio special Firewire series M-Audio Firewire 1814 has a quirk, ProjectMix I/O also has. They transmit empty packet with wrong value of dbc incremented by 8 at high sampling rate. According to IEC 61883-1, this value should be the same as the one in previous packet. This commit adds a flag named as CIP_EMPTY_HAS_WRONG_DBC. With flag, the value of dbc in empty packet is overwittern by an expected value. This is an example of this quirk: CIP Header 0 CIP Header 1 Payload size 010D0000 9004F759 210 010D0010 90040B59 210 010D0020 90042359 210 01020028 9004FFFF 2 <- 010D0030 90043759 210 010D0040 90044B59 210 010D0050 90046359 210 01020058 9004FFFF 2 <- 010D0060 90047759 210 010D0070 90048B59 210 010D0080 9004A359 210 01020088 9004FFFF 2 <- 010D0090 9004B759 210 010D00A0 9004CB59 210 010D00B0 9004E359 210 010200B8 9004FFFF 2 <- 010D00C0 9004F759 210 010D00D0 90040B59 210 010D00E0 90042359 210 Signed-off-by:

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. Tested-by: Darren Anderson <darrena092@gmail.com> (ProjectMix I/O) Signed-off-by:

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:

This commit allows this driver to support all of models which Yamaha produced with DM1000/BeBoB. They are: - GO44 - GO46 This commit adds Yamaha specific operations. To get source of clock, AV/C Audio Subunit command is used. I note that their appearances are similar to some models of TerraTec; 'Go44' is similar to 'PHASE 24 FW' and 'GO46' is similar to 'PHASE X24 FW'. But their combination of Audio/Music subunits is a bit different. Signed-off-by:

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. Signed-off-by:

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.

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. Signed-off-by:

Fireworks firmware version 5.5 reports fix interval for dbc in each packet.

Fireworks has a quirk for the value of dbc field in transmitted packets. For Fireworks, dbc means the end of events in current packet. This is out of specification. For example, AudioFire4: CIP0 CIP1 Payload 01070092 90FFFFFF 02 0107009A 9001E17B 3A <- 010700A2 9001F6E5 3A 010700A2 90FFFFFF 02 010700AA 9001104F 3A <- 010700B2 900125B9 3A 010700BA 90013B23 3A 010700BA 90FFFFFF 02 010700C2 9001548E 3A <- 010700CA 900169F8 3A 010700CA 90FFFFFF 02 010700D2 90018362 3A <- 010700DA 900198CC 3A According to IEC 61883-1/6, a packet following to empty packet has the same value for its dbc. But for Fireworks, it's incremented and empty packet has the same value as previous packet in dbc field. This commit adds a flag for Fireworks and some codes to checking dbc continuity.

Fireworks manages connections by CMP and can transmit/receive AMDTP streams with a few quirks. This commit adds functionality to start/stop the streams. Major Fireworks products don't support 'SYT-Match' clock source mode, except for AudioFire12/8(till 2009 July) with firmware version 1.0. Already in previous commit, this driver don't support such old firmwares. So this commit adds support for non 'SYT-Match' clock source modes. I note that this driver has a short gap for MIDI streams when starting PCM stream. When AMDTP streams are running only for MIDI data and PCM data is going to be joined at different sampling rate, then AMDTP streams are stopped once and started again after changing sampling rate. Unfortunately, Fireworks is not fully compliant to IEC 61883-1/6. Some commits following to this commit add these quirks. Signed-off-by:
