Hi ,
snd_usb_hardware is defined in sound/usb/pcm.c as :
static struct snd_pcm_hardware snd_usb_hardware =
{
.....
.buffer_bytes_max = 1024 * 1024,
.period_bytes_min = 64,
.period_bytes_max = 512 * 1024,
.periods_min = 2,
.periods_max = 1024,
};
here periods_max is intialized with value = 1024 .
but going by buffer_bytes_max and period_bytes_min value defined above ,
periods_max = ( buffer_bytes_max / period_bytes_min ) = 16384 .
why this upper cap of 1024 is maintained for periods_max even though from
calculation it comes as 16384 ?
Thanx & Regards
