β¨ snd_hdac_dsp_trigger(9) β the Kernel API Manual moment π
okay so bestie, welcome to the Kernel API Manual, and today's main character is snd_hdac_dsp_trigger β the little function that literally starts and stops DSP loading. that's it. that's the whole vibe. no cap. π
πΈ NAME πΈ
snd_hdac_dsp_trigger β start / stop DSP loading β¨
like, you're either hitting play or hitting stop on the DSP loading situation. there is no in-between, bestie.
π¦ SYNOPSIS π¦
void snd_hdac_dsp_trigger (struct hdac_stream *azx_dev , bool start );
yes, that's the whole signature, and yes, you should copy it exactly β character for character, no improvising π
π ARGUMENTS π
azx_devβ the HD-audio core stream that's being used for DSP loading. this is your lil stream bestie, the one doing the actual work π«Άstartβ the trigger: start or stop.boolenergy. you pick which way the vibe goes β
π SEE ALSO π
the kernel file lives at ./sound/hda/core/stream.c, and honestly the whole friend group shows up here β go say hi:
