snd_hda_get_devices(9)
π NAME π
okay so bestie, welcome to snd_hda_get_devices(9) from the Kernel API Manual β and the whole vibe is literally copy device list without cache. not me explaining the cache drama, it's right there in the name. π
β¨ SYNOPSIS β¨
unsigned int snd_hda_get_devices (struct hda_codec *codec , hda_nid_t
nid , u8 *dev_list , unsigned int max_devices );
π ARGUMENTS π
codecβ the HDA codec. your main-character struct, fr fr.nidβ NID of the pin to parse. yes bestie, the pin. parse it. π¦dev_listβ device list array. this is where the list goes.max_devicesβ max. number of devices to store. that's the cap, no cap. π
π« DESCRIPTION π«
Copy the device list. lowkey important: this info is dynamic and so not cached β do not expect a lil saved copy, bestie. currently it's called only from hda_proc.c, so it's not exported. periodt. β¨
