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 oxfw 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. This commit fixes the bug. Fixes: 4f380d00 ("ALSA: oxfw: configure packet format in pcm.hw_params callback") Signed-off-by:

Extension Unit (XU) is used to have a compatible layout with Processing Unit (PU) on UAC1, and the usb-audio driver code assumed it for parsing the descriptors. Meanwhile, on UAC2, XU became slightly incompatible with PU; namely, XU has a one-byte bmControls bitmap while PU has two bytes bmControls bitmap. This incompatibility results in the read of a wrong address for the last iExtension field, which ended up with an incorrect string for the mixer element name, as recently reported for Focusrite Scarlett 18i20 device. This patch corrects this misalignment by introducing a couple of new macros and calling them depending on the descriptor type.

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 18f5ed36 ("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'.

To save power, the hda hdmi driver in ASoC invokes snd_hdac_ext_bus_link_put to disable CORB/RIRB buffers DMA if there is no user of bus and invokes snd_hdac_ext_bus_link_get to set up CORB/RIRB buffers when it is used. Unsolicited responses is disabled in snd_hdac_bus_stop_cmd_io called by snd_hdac_ext_bus_link_put , but it is not enabled in snd_hdac_bus_init_cmd_io called by snd_hdac_ext_bus_link_get. So for put-get sequence, Unsolicited responses is disabled and headphone can't be detected by hda codecs. Now unsolicited responses is only enabled in snd_hdac_bus_reset_link which resets controller. The function is only called for setup of controller. This patch enables Unsolicited responses after RIRB is initialized in snd_hdac_bus_init_cmd_io which works together with snd_hdac_bus_reset_link to set up controller. Tested legacy hda driver and SOF driver on intel whiskeylake. Reviewed-by:

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.

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:

Shifting the integer value 1 is evaluated using 32-bit arithmetic and then used in an expression that expects a 64-bit value, so there is potentially an integer overflow. Fix this by using the BIT_ULL macro to perform the shift. [ Note: as of the time being, no actual integer overflow hits because all values are less than 32bit, not including the extended 3-byte or DSD formats. But this is the right fix for future usage, of course. -- tiwai ] Addresses-Coverity: ("Unintentional integer overflow") Signed-off-by: -

There are a couple of left shifts of unsigned 8 bit values that first get promoted to signed ints and hence get sign extended on the shift if the top bit of the 8 bit values are set.

This adds 4 SND_PCI_QUIRK(...) lines for several barebone models of the ODM Clevo. The model names are written in regex syntax to describe/match all clevo models that are similar enough and use the same PCI SSID that this fixup works for them. Additionally the lines regarding SSID 0x96e1 and 0x97e1 didn't fix audio for the all our Clevo notebooks using these SSIDs (models Clevo P960* and P970*) since ALC1220_FIXP_CLEVO_PB51ED_PINS swapped pins that are not necesarry to be swapped. This patch initiates ALC1220_FIXUP_CLEVO_P950 instead for these model and fixes the audio. Fixes: 80690a27 ("ALSA: hda/realtek - Add quirk for Tuxedo XC 1509") Signed-off-by:

The recent USB core code performs sanity checks for the given pipe and EP types, and it can be hit by manipulated USB descriptors by syzbot. For making syzbot happier, this patch introduces a local helper for a sanity check in the driver side and calls it at each place before the message handling, so that we can avoid the WARNING splats.

In ALSA firewire-motu driver, some tracepoints are supported to probe vendor-specific data fields for SPH and status/control messages in payload of isochronous packet. 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. From userspace, direction is specified by filtering for src/dst fields in the structure. Signed-off-by:

This reverts commit e703965a. When creating this patch, I compared the value of src field to the value of first byte of cip_header field (SID) in tracing event. But in this test I used a device which has a quirk to transfer isochronous packet with invalid SID. The original change is valid.

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:

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:

In current implementation, establishment connection corresponds to allocation of isochronous resources. Although this is an ideal implementation of CMP described in IEC 61883-1, it's not enough efficient to recover PCM substream multiplexed in packet streaming. The packet streaming can always restart on the same allocated isochronous resources even if the previous packet streaming corrupted. This commit splits allocation of isochronous resources from establishment of connection so that CMP runs with allocated isochronous resources. Signed-off-by:
