fdd51b3e - ALSA: firewire: Use -y instead of -objs in Makefile

Tue, 07 May 2024 13:55:07 +0000

ALSA: firewire: Use *-y instead of *-objs in Makefile*-objs suffix is reserved rather for (user-space) host programs whileusually *-y suffix is used for kernel drivers (although *-objs worksfor that purpose for now).Let's correct the old usages of *-objs in Makefiles.Cc: Takashi Sakamoto Signed-off-by: Takashi Iwai Reviewed-by: Takashi Sakamoto Reviewed-by: Andy Shevchenko Reviewed-by: Jaroslav Kysela Link: https://lore.kernel.org/r/20240507135513.14919-8-tiwai@suse.de List of files: /linux-6.15/sound/firewire/digi00x/Makefile

9fbfd38b - ALSA: firewire-digi00x: add support for MIDI ports corresponding to isochronous packet streaming

Sun, 11 Oct 2015 03:30:16 +0000

ALSA: firewire-digi00x: add support for MIDI ports corresponding to isochronous packet streamingThis commit adds MIDI functionality to capture/playback MIDI messagesfrom/to physical MIDI ports. These messages are transferred in isochronouspackets.When no substreams request AMDTP streams to run, this driver starts thestreams at current sampling rate. When other substreams start at differentsampling rate, the streams are stopped temporarily, then start again atrequested sampling rate. This operation can generate missing MIDI bytes,thus it's preferable to start PCM substreams at favorite sampling rate inadvance.Digi 002/003 console also has a set of MIDI port for physical controls.These ports are added in later commits.Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/digi00x/Makefile

44b73088 - ALSA: firewire-digi00x: add support for asynchronous messaging

Wed, 30 Sep 2015 00:39:22 +0000

ALSA: firewire-digi00x: add support for asynchronous messagingDigi 002/003 family uses asynchronous transaction for messaging.The address to transmit this message is stored on a certain register.This commit allocates a range of address on OHCI 1394 host controllerto handle the messaging. As long as I know, the purpose of this messageseems to notify lost of synchronization. While, the meaning of contentof the message is not clear.Actual examples of this messaging: * When clock source is set as internal: - 0x00007051 - 0x00007052 - 0x00007054 - 0x00007057 - 0x00007058 * When clock source is set as somewhat external: - 0x00009000 - 0x00009010 - 0x00009020 - 0x00009021 - 0x00009022The lost often occurs when using internal clock source. In this case,users hear sounds with quite short gap every several minutes. In fact,the lost is recovered temporarily.When using with external clock source, the lost seems not to occur. Themechanism is not clear yet.Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/digi00x/Makefile

660dd3d5 - ALSA: firewire-digi00x: add hwdep interface

Wed, 30 Sep 2015 00:39:21 +0000

ALSA: firewire-digi00x: add hwdep interfaceThis commit adds hwdep interface so as the other sound drivers for unitson IEEE 1394 bus have.This interface is designed for mixer/control applications. By using thisinterface, an application can get information about firewire node, canlock/unlock kernel streaming and can get notification at starting/stoppingkernel streaming.Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/digi00x/Makefile

0120d0f1 - ALSA: firewire-digi00x: add PCM functionality

Wed, 30 Sep 2015 00:39:20 +0000

ALSA: firewire-digi00x: add PCM functionalityThis commit adds PCM functionality to transmit/receive PCM samples.Any PCM substreams are jointed because incoming/outgoing AMDTP streamsare bound. When one of PCM substream is running or external clock sourceis selected, current sampling rate is used. Else, the sampling rate ischanged as an userspace application requests.Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/digi00x/Makefile

927f17dc - ALSA: firewire-digi00x: add proc node to show clock status

Wed, 30 Sep 2015 00:39:19 +0000

ALSA: firewire-digi00x: add proc node to show clock statusThis commit adds proc node to show current clock status for debugging.As long as testing Digi 002 rack, registers can show local clock rate,local clock source. When external clock input such as S/PDIF isconnected, the registers show the detection and external clock rate.Additionally, the registers show the mode of optical digital inputinterface. Although, a tester with Digi 003 rack reports this makes nosense. Further investigation is required for Digi 003 series.Besides, in Digi 002 rack, the S/PDIF format must be IEC 60958-4,so-called professional.Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/digi00x/Makefile

3a2a1797 - ALSA: firewire-digi00x: add stream functionality

Wed, 30 Sep 2015 00:39:18 +0000

ALSA: firewire-digi00x: add stream functionalityThis commit adds a functionality to manage streaming.The streaming is not controlled by CMP in IEC 61883-6. It's controlled byIEEE 1394 write transaction to certain addresses.Several clock sources are available, while there're no differences aboutpacket transmission. The value of SYT field in transmitted packets isalways zero. Thus, streams in both direction don't build synchronization.And the device always requires received packets to transmit packets. Thisdriver keeps to transfer outgoing stream even if they're not required.Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/digi00x/Makefile

163ae6f3 - ALSA: firewire-digi00x: add data block processing layer

Wed, 30 Sep 2015 00:39:17 +0000

ALSA: firewire-digi00x: add data block processing layerDigi 002/003 family uses its own format for data blocks. The format isquite similar to AM824 in IEC 61883-6, while there're some differences: * The Valid Bit Length (VBL) code is always 0x40 in Multi-bit Linear Audio (MBLA) data channel. * The first data channel includes MIDI messages, against IEC 61883-6 recommendation. * The Counter field is always zero in MIDI conformant data channel. * Sequence multiplexing in IEC 61883-6 is not applied to the MIDI conformant data channel. * PCM samples are scrambled in received AMDTP packets. We call the way as Double-Oh-Three (DOT). The algorithm was discovered by Robin Gareus and Damien Zammit in 2012.This commit adds data processing layer to satisfy these differences.There's a quirk about transmission mode for received packets. When thisdriver applies non-blocking mode to outgoing packets with isochronouschannel 2 or more, after 15 to 20 seconds since playbacking, any PCMsamples causes noisy sound on the device. With isochronous channel 0 or 1,this doesn't occur. As long as I investigated, this quirk is not observedwhen applying blocking mode to the received packets.This driver applies blocking mode to outgoing packets, while non-blockingmode to incoming packgets.Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai List of files: /linux-6.15/sound/firewire/digi00x/Makefile
