2019-07-08ALSA: firewire-lib: code refactoring for local variablesTakashi Sakamoto
It's better to use int type for loop index. For consistency, the name of local variable for the number of data block should be plural. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2019-07-08ALSA: firewire-lib: fix initial value of data block count for IR context ↵Takashi Sakamoto
without CIP_DBC_IS_END_EVENT For IR context, ALSA IEC 61883-1/6 engine uses initial value of data block counter as UINT_MAX, to detect first isochronous packet in the middle of packet streaming. At present, when CIP_DBC_IS_END_EVENT is not used (i.e. for drivers except for ALSA fireworks driver), the initial value is used as is for tracepoints event. However, the engine can detect the value of dbc field in the payload of first isochronous packet and the value should be assigned to the event. This commit fixes the bug.

context with CIP_NO_HEADER For IR context, ALSA IEC 61883-1/6 engine uses initial value of data block counter as UINT_MAX, to detect first isochronous packet in the middle of packet streaming. At present, when CIP_NO_HEADER is used (i.e. for ALSA fireface driver), the initial value is used for tracepoints event. 0x00 should be for the event when the initial value is UINT_MAX because isochronous packets with CIP_NO_HEADER option has no field for data block count.

2019-07-07firewire-motu: fix wrong reference count for stream functionality at error ↵Takashi Sakamoto
path of rawmidi interface In IEC 61883-6, several types of sampling data can be multiplexed into payload of common isochronous packet (CIP). For typical audio and music units, PCM samples and MIDI messages are multiplexed into one packet streaming. ALSA firewire-motu driver allows applications of rawmidi interface to start packet streaming for transmission of MIDI messages. However at error path, the reference count of stream functionality is not operated correctly. This can brings a bug that packet streaming is not stopped when all referrers release the count.

2019-07-01ALSA: firewire-lib/fireworks: fix miss detection of received MIDI messagesTakashi Sakamoto
In IEC 61883-6, 8 MIDI data streams are multiplexed into single MIDI conformant data channel. The index of stream is calculated by modulo 8 of the value of data block counter. In fireworks, the value of data block counter in CIP header has a quirk with firmware version v5.0.0, v5.7.3 and v5.8.0. This brings ALSA IEC 61883-1/6 packet streaming engine to miss detection of MIDI messages. This commit fixes the miss detection to modify the value of data block counter for the modulo calculation. For maintainers, this bug exists since a commit 18f5ed365d3f ("ALSA: fireworks/firewire-lib: add support for recent firmware quirk") in Linux kernel v4.2. There're many changes since the commit. This fix can be backported to Linux kernel v4.4 or later. I tagged a base commit to the backport for your convenience. Besides, my work for Linux kernel v5.3 brings heavy code refactoring and some structure members are renamed in 'sound/firewire/amdtp-stream.h'. The content of this patch brings conflict when merging -rc tree with this patch and the latest tree. I request maintainers to solve the conflict to replace 'tx_first_dbc' with 'ctx_data.tx.first_dbc'.

2019-06-28ALSA: firewire-lib: fix to process MIDI conformant data channel for AM824 formatTakashi Sakamoto
In IEC 61883-6, 8 MIDI data streams are multiplexed into single MIDI conformant data channel. The index of stream is calculated by modulo 8 of the value of data block counter. Therefore data block processing layer requires valid value of data block counter. In recent changes of ALSA IEC 61883-1/6 engine, the value of data block counter is changed before calling data block processing layer. This brings miss detection of MIDI messages in non-blocking transmission method is used. This commit fixes the bug by changing chached data block counter after calling data block processing layer.

event for IR context For debugging purpose, ALSA IEC 61883-1/6 engine has tracepoints event. In current implementation, next data block counter is stored as current data block counter before probing the event for IR isoc context. It's not good to check current packet parameter. This commit changes to assign the next data block counter after probing the event. Besides, Fireworks devices has a quirk to transfer isoc packet with data block counter for the last data block. For this quirk, the assignment is done before calling data block processing layer. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-06-24ALSA: firewire-motu: unify common tracepoints for both directionTakashi Sakamoto

At present, the events of tracepoints are unique each of direction, however the pair of events has the same structure and print format. It's possible to unify the pair. This commit unifies the pair.

But in this test I used a device which has a quirk to transfer isochronous packet with invalid SID. The original change is valid.

2019-06-18ALSA: firewire-motu: update isochronous resources when starting packet ↵Takashi Sakamoto
streaming after bus-reset After bus reset, isochronous resource manager releases all of allocated isochronous resources. The nodes to transfer isochronous packet should request reallocation of the resources. However, between the bus-reset and invocation of 'struct fw_driver.update' handler, ALSA PCM application can detect this situation by XRUN because the target device cancelled to transmit packets once bus-reset occurs. Due to the above mechanism, ALSA fireface driver just stops packet streaming in the update handler, thus pcm.prepare handler should request the reallocation. This commit requests the reallocation in pcm.prepare callback when bus generation is changed. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2019-06-18ALSA: firewire-motu: reserve/release isochronous resources in ↵Takashi Sakamoto
pcm.hw_params/hw_free callbacks Once allocated, isochronous resources are available for packet streaming, even if the streaming is cancelled. For this reason, current implementation handles allocation of the resources and starting packet streaming at the same time. However, this brings complicated procedure to start packet streaming. This commit separates the allocation and starting. The allocation is done in pcm.hw_params callback and available till pcm.hw_free callback. Even if any XRUN occurs, pcm.prepare callback is done to restart packet streaming without releasing/allocating the resources. There are two points to stop packet streaming; in pcm.hw_params and pcm.prepare callbacks. The former point is a case that packet streaming is already started for any MIDI substream then packet streaming is requested with different sampling transfer frequency for any PCM substream. The latter point is cases of any XRUN or packet queueing error. Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
