* ALSA: firewire-lib: add tracepoints to dump a part of isochronous packet dataTakashi Sakamoto2016-05-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When audio and music units have some quirks in their sequence of packet, it's really hard for non-owners to identify the quirks. Although developers need dumps for sequence of packets, it's difficult for users who have no knowledges and no equipments for this purpose. This commit adds tracepoints for this situation. When users encounter the issue, they can dump a part of packet data via Linux tracing framework as long as using drivers in ALSA firewire stack. Additionally, tracepoints for outgoing packets will be our help to check and debug packet processing of ALSA firewire stack. This commit newly adds 'snd_firewire_lib' subsystem with 'in_packet' and 'out_packet' events. In the events, some attributes of packets and the index of packet managed by this module are recorded per packet. This is an usage: $ trace-cmd record -e snd_firewire_lib:out_packet \ -e snd_firewire_lib:in_packet /sys/kernel/tracing/events/snd_firewire_lib/out_packet/filter /sys/kernel/tracing/events/snd_firewire_lib/in_packet/filter Hit Ctrl^C to stop recording ^C $ trace-cmd report trace.dat ... 23647.033934: in_packet: 01 4073 ffc0 ffc1 00 000f0040 9001b2d1 122 44 23647.033936: in_packet: 01 4074 ffc0 ffc1 00 000f0048 9001c83b 122 45 23647.033937: in_packet: 01 4075 ffc0 ffc1 00 000f0050 9001ffff 002 46 23647.033938: in_packet: 01 4076 ffc0 ffc1 00 000f0050 9001e1a6 122 47 23647.035426: out_packet: 01 4123 ffc1 ffc0 01 010f00d0 9001fb40 122 17 23647.035428: out_packet: 01 4124 ffc1 ffc0 01 010f00d8 9001ffff 002 18 23647.035429: out_packet: 01 4125 ffc1 ffc0 01 010f00d8 900114aa 122 19 23647.035430: out_packet: 01 4126 ffc1 ffc0 01 010f00e0 90012a15 122 20 (Here, some common fields are omitted so that a line to be within 80 characters.) ...

* ALSA: oxfw: obsolete scs1x moduleTakashi Sakamoto2015-12-221-2/+0
| | | | | | | | | | | | | | | | | | | | | Now ALSA oxfw driver gains functionalities which scs1x module has. This commit obsoletes the scs1x module, and adds a line of MODULE_ALIAS to load oxfw module instead of scs1x module. In scs1x module, the name of 'shortname' field is fixed as 'SCS1x'. This field is used to name MIDI ports for both of SCS.1m and SCS.1d. This is not good because typically some SCS.1m and SCS.1d are used in the same system. It's better to distinguish them according to name of the ports. This commit applies model name in config ROM to the 'shortname'. For the name of 'driver' and 'longname', this commit uses the same way applied to the other models. This change may not bring disadvantages to users because userspace applications use ALSA rawmidi or seq interface and these interfaces are not influenced by them directly.

* ALSA: firewire-tascam: add skeleton for TASCAM FireWire seriesTakashi Sakamoto2015-10-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a new driver for TASCAM FireWire series. In this commit, this driver just creates/removes card instance according to bus event. More functionalities will be added in following commits. TASCAM FireWire series consists of: * PDI 1394P23 for IEEE 1394 PHY layer * PDI 1394L40 for IEEE 1394 LINK layer and IEC 61883 interface * XILINX XC9536XL * XILINX Spartan-II XC2S100 * ATMEL AT91M42800A Ilya Zimnovich had investigated TASCAM FireWire series in 2011, and discover some features of his FW-1804. You can see a part of his research in FFADO project. http://subversion.ffado.org/wiki/Tascam A part of my work are based on Ilya's investigation, while this series doesn't support the FW-1804, because of a lack of config ROM information and its protocol detail, especially for PCM channels. I observed that FW-1884 and FW-1082 don't work properly with 1394 OHCI controller based on VT6315. The controller can actually communicate packets to these models, while these models generate no sounds. It may be due to the PHY/LINK layer issues. Using 1394 OHCI controller produced by the other vendors such as Texas Instruments may work. Or adding another node on the bus.
