ALSA: bebob: Use a signed return type for get_formation_index

2016-02-17T20:30:58+00:00

commit 07905298e4d5777eb58516cdc242f7ac1ca387a2 upstream. The return type "unsigned int" was used by the get_formation_index function despite of the aspect that it will eventually return a negative error code. So, change to signed int and get index by reference in the parameters. Done with the help of Coccinelle.

ALSA: bebob: use correct type for __be32 data

2015-10-19T09:57:03+00:00

In former commit, metering is supported for BeBoB based models customized by M-Audio. The data in transaction is aligned to big-endianness, while in the driver code u16 typed variable is assigned to the data. This causes sparse warnings. bebob_maudio.c:651:31: warning: cast to restricted __be16 bebob_maudio.c:651:31: warning: cast to restricted __be16 bebob_maudio.c:651:31: warning: cast to restricted __be16 bebob_maudio.c:651:31: warning: cast to restricted __be16 This commit fixes this bug by using __be16 variable for the data.

ALSA: fireworks/bebob/oxfw/dice: enable to make as built-in

2015-10-18T07:08:11+00:00

When committed to upstream, these four modules had wrong entries for Makefile. This forces them to be loadable modules even if they're set as built-in. This commit fixes this bug.

ALSA: bebob: constify various snd_bebob structures

ALSA: bebob: support Firewire I/O card of Mackie Onyx 1220/1620/1640

2015-10-04T15:21:34+00:00

Current ALSA BeBoB drivers has an entry for this model, while the value of vendor ID seems to be wrong according to an user's report. The vendor had released no updated firmware, thus we can judge that this model had not changed the content of its config ROM. It's reasonable to fix the ID according to the report. $ ./linux-firewire-utils/src/crpp < /sys/bus/firewire/devices/fw1/config_rom ROM header and bus information block ----------------------------------------------------------------- 400 0425720f bus_info_length 4, crc_length 37, crc 29199 404 31333934 bus_name "1394" 408 f0646122 irmc 1, cmc 1, isc 1, bmc 1, pmc 0, cyc_clk_acc 100, max_rec 6 (128), max_rom 1, gen 2, spd 2 (S400) 40c 00000ff2 company_id 00000f | 410 00004697 device_id f200004697 | EUI-64 00000ff200004697 root directory ----------------------------------------------------------------- 414 000859be directory_length 8, crc 22974 418 04000082 hardware version 41c 0c0083c0 node capabilities per IEEE 1394 420 03000ff2 vendor 424 8100000a --> descriptor leaf at 44c 428 17010065 model 42c 8100000d --> descriptor leaf at 460 430 13000910 version 434 d1000001 --> unit directory at 438 unit directory at 438 ----------------------------------------------------------------- 438 0004ccec directory_length 4, crc 52460 43c 1200a02d specifier id: 1394 TA 440 13010001 version: AV/C 444 17010065 model 448 8100000d --> descriptor leaf at 47c descriptor leaf at 44c ----------------------------------------------------------------- 44c 0004152a leaf_length 4, crc 5418 450 00000000 textual descriptor 454 00000000 minimal ASCII 458 4d61636b "Mack" 45c 69650000 "ie" descriptor leaf at 460 ----------------------------------------------------------------- 460 000612b5 leaf_length 6, crc 4789 464 00000000 textual descriptor 468 00000000 minimal ASCII 46c 4f6e7978 "Onyx" 470 20466972 " Fir" 474 65776972 "ewir" 478 65000000 "e" descriptor leaf at 47c ----------------------------------------------------------------- 47c 000612b5 leaf_length 6, crc 4789 480 00000000 textual descriptor 484 00000000 minimal ASCII 488 4f6e7978 "Onyx" 48c 20466972 " Fir" 490 65776972 "ewir" 494 65000000 "e" $ cat /proc/asound/card3/firewire/firmware Manufacturer: bridgeCo Protocol Ver: 1 Build Ver: 0 GUID: 0x00000FF200004697 Model ID: 0x82 Model Rev: 1 Firmware Date: 20040430 Firmware Time: 131527 Firmware ID: 0x10065 Firmware Ver: 2320 Base Addr: 0x20080000 Max Size: 1572864 Loader Date: 20040430 Loader Time: 112036 Reported-by: Andrzej Gansiniec Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: firewire-lib: rename macros with AM824 prefix

ALSA: firewire-lib: rename PCM format helper function

2015-09-29T10:49:04+00:00

Setting the format of PCM substream to AMDTP stream structure is important to set a handler to copy actual PCM samples between buffers. The processing should be in data block processing layer because essentially it has no relationship to packet streaming. This commit renames PCM format setting function to prepare for integrating AM824 layer. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai

ALSA: firewire-lib: move MIDI trigger helper function to AM824 layer

2015-09-29T10:48:49+00:00

In IEC 61883-6, MIDI messages are transferred in MIDI conformant data channel. Essentially, packet streaming layer is not responsible for MIDI functionality. This commit moves MIDI trigger helper function from the layer to AM824 layer. The rest of codes related to MIDI functionality will be moved in later commits.

ALSA: firewire-lib: add helper functions to set positions of data channels

2015-09-29T10:48:36+00:00

In IEC 61883-6, several types of data are available in AM824 format. The data is transferred in each data channel. The position of data channel in data block differs depending on model. Current implementation has an array to map the index of data channel in an data block to the position of actual data channel. The implementation allows each driver to access the mapping directly. In later commit, the mapping is in specific structure pushed into an opaque pointer. Helper functions are required. This commit adds the helper functions for this purpose. In IEC 61883-6, AM824 format supports many data types, while this specification easily causes over-engineering. Current AM824 implementation is allowed to handle two types of data, Multi Bit Linear Audio data (=PCM samples) and MIDI conformant data (=MIDI messages).

ALSA: firewire-lib: move PCM substream constraint to AM824 layer

2015-09-29T10:48:19+00:00

In IEC 61883-6, PCM frames are transferred in Multi Bit Linear Audio data channel. The data channel transfers 16/20/24 bit PCM samples. Thus, PCM substream has a constrain about it. This commit moves codes related to the constraint from packet streaming layer to AM824 data block processing layer. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai
