Commit Message

Abel Vesa Sept. 2, 2022, 1:13 p.m. UTC 
In order to be able to start the adsp listener for audiopd using adsprpcd,
we need to add the corresponding ioctl for creating a static process.
On that ioctl call we need to allocate the heap. Allocating the heap needs
to be happening only once and needs to be kept between different device
open calls, so attach it to the channel context to make sure that remains
until the RPMSG driver is removed. Then, if there are any VMIDs associated
with the static ADSP process, do a call to SCM to assign it.
And then, send all the necessary info related to heap to the DSP.
