Hi All,
will ALSA framework provide any customized IOCTL functionality in PCM platform driver.
No.
in my system there is a requirement to get some information from DSP to user space and I am thinking to add IOCTL's, is there any method to accommodate or how we can address this issue?
You can use hwdep device for any extra methods.
We need to tie this ioctl with the on going DSP session which will be difficult When used with hwdep interface.
