[Question] how to get underlying file descriptors
by GitHub issues - opened 03 Jun '24

03 Jun '24

alsa-project/alsa-lib issue #399 was opened from pfeatherstone: I would like to use Alsa with the asio c++ library. I think all I need is the underlying file descriptor(s) for the device which I can then pass to Asio for polling and do all my asyncio. At the moment you're forced to use pollfd using snd_pcm_poll_descriptors(). Can I just read the fds or are there subtleties?

[PATCH 0/7] ALSA: hda: Improvements to hda_component
by Simon Trimmer 01 Jun '24

01 Jun '24

This series of patches makes sure that the existing consumers of the infrastructure unbind their interface before they begin destroying the driver, moves duplicated members from the instanced component structures into a new parent structure and introduces locking so that consumers of the interface do not use stale data. Simon Trimmer (7): ALSA: hda: cs35l56: Component should be unbound before deconstruction ALSA: hda: cs35l41: Component should be unbound before deconstruction ALSA: hda/tas2781: Component should be unbound before deconstruction ALSA: hda: hda_component: Introduce component parent structure ALSA: hda: hda_component: Change codecs to use component parent structure ALSA: hda: hda_component: Move codec field into the parent ALSA: hda: hda_component: Protect shared data with a mutex sound/pci/hda/cs35l41_hda.c | 47 +++++++++++--------- sound/pci/hda/cs35l56_hda.c | 29 +++++++------ sound/pci/hda/hda_component.c | 76 ++++++++++++++++++++------------- sound/pci/hda/hda_component.h | 48 ++++++++++++++------- sound/pci/hda/patch_realtek.c | 17 ++++---- sound/pci/hda/tas2781_hda_i2c.c | 37 ++++++++-------- 6 files changed, 148 insertions(+), 106 deletions(-) -- 2.34.1
