ALSA: firewire: lib: Use guard() for mutex locks

2025-08-30T08:02:21+00:00

Replace the manual mutex lock/unlock pairs with guard() for code simplification. Only code refactoring, and no behavior change. Reviewed-by: Takashi Sakamoto Signed-off-by: Takashi Iwai Link: https://patch.msgid.link/20250828132802.9032-11-tiwai@suse.de

ASoC: Updates for v5.3 This is a very big update, mainly thanks to Morimoto-san's refactoring work and some fairly large new drivers. - Lots more work on moving towards a component based framework from Morimoto-san. - Support for force disconnecting muxes from Jerome Brunet. - New drivers for Cirrus Logic CS47L35, CS47L85 and CS47L90, Conexant CX2072X, Realtek RT1011 and RT1308.

ALSA: firewire-lib: split allocation of isochronous resources from establishment of connection

2019-06-17T06:18:36+00:00

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.

ALSA: firewire-lib: Add a new function to check others' connection

2014-05-26T12:22:46+00:00

Plug Control Registers have two fields related to the number of established connections, one is 'Broadcast connection counter' and another is 'Point-to-point connection counter'. The driver can know there are established connections or not to check these fields. This commit is for considering about JACK/FFADO streaming. Currently, when JACK/FFADO starts its streaming to the device, cmp_connection_establish() is failed expectedly. This seems to be enough but there are some devices which needs to change sampling frequency before trying to establish connections. For such devices, this functionality is needed.

ALSA: firewire-lib: Add handling output connection by CMP

This patch adds some macros, codes with condition of direction and new functions to handle output connection. Once cmp_connection_init() is executed with its direction, CMP input and output connection can be handled by the same way. Signed-off-by: Takashi Sakamoto Signed-off-by: Takashi Iwai
