Hi All! I am serching for an mechanism which does the following: visiblity control: Where a hardware buffer has to be visible to the user space. I believe I can use mmap. async notification: As soon as the hardware buffer completion is done. It has to be signalled/callbacked to the user-space, and the corresponding handler to the signal runs. Can any one point out the source/docs for such a mechanism.
