2019-07-01ALSA: hda: Fix a headphone detection issue when using SOFRander Wang1-3/+2
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.

2019-06-28ALSA: firewire-lib: fix to process MIDI conformant data channel for AM824 formatTakashi Sakamoto1-12/+14
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.

2019-06-28ALSA: firewire-lib: cache next data_block_counter after probing tracepoints ↵Takashi Sakamoto1-22/+26
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>
2019-06-28ALSA: xen-front: fix unintention integer overflow on left shiftsColin Ian King1-2/+2
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: Colin Ian King <colin.king@canonical.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

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.

2019-06-24ALSA: firewire-motu: unify common tracepoints for both directionTakashi Sakamoto2-58/+20
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: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

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 Sakamoto1-0/+11
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 Sakamoto4-56/+84
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>

establishment of connection 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.
