Hi, (resend to linux1394-devel since the original post has so many receivers. Please refer to it for any reply: https://lore.kernel.org/lkml/202...@sa.../) This series of changes updates my previous RFT[1] to apply for v6.12 kernel. For the detail, please refer to the previous one. To Iwai-san, this series includes the change for sound subsystem as well. All of changes are specific to ALSA firewire stack, so I would like to send it to Linus as the part of firewire subsystem updates if you do not mind it. Changes from the RFT: * WQ_FREEZABLE is newly supported in the workqueue * Improve code comment in IEC 61883-1/6 packet streaming engine * Avoid dead lock in the calls of workqueue sync API [1] https://lore.kernel.org/lkml/202...@sa.../ Regards Takashi Sakamoto (5): firewire: core: allocate workqueue to handle isochronous contexts in card firewire: core: add local API to queue work item to workqueue specific to isochronous contexts firewire: ohci: operate IT/IR events in sleepable work process instead of tasklet softIRQ firewire: core: non-atomic memory allocation for isochronous event to user client ALSA: firewire: use nonatomic PCM operation drivers/firewire/core-card.c | 33 ++++++++++++-- drivers/firewire/core-cdev.c | 4 +- drivers/firewire/core-iso.c | 30 ++++++++++++- drivers/firewire/core.h | 14 +++++- drivers/firewire/ohci.c | 57 +++++++++++++++++++----- include/linux/firewire.h | 3 ++ sound/firewire/amdtp-stream.c | 34 +++++++++++--- sound/firewire/bebob/bebob_pcm.c | 1 + sound/firewire/dice/dice-pcm.c | 1 + sound/firewire/digi00x/digi00x-pcm.c | 1 + sound/firewire/fireface/ff-pcm.c | 1 + sound/firewire/fireworks/fireworks_pcm.c | 1 + sound/firewire/isight.c | 1 + sound/firewire/motu/motu-pcm.c | 1 + sound/firewire/oxfw/oxfw-pcm.c | 1 + sound/firewire/tascam/tascam-pcm.c | 1 + 16 files changed, 157 insertions(+), 27 deletions(-) -- 2.43.0 |
