Hi
What actually happens is that I have some
proprietary binary driver that performs zero copy
DMA into user buffers. For this to be
done it forces pages composing these
buffers to be allocated RAM frames and
locks them, so page table entries for
these buffers shouldn't change and these
entries are exactly what I want to see.
( I'll try to write kernel module that
will do it)
regards,
Boris

Is it possible to print/dump pagetable of a
given process ( through /proc filesystem maybe ) ?
Not out of the box. It's fairly trivial to implement in the kernel, if
you don't mind "stopping the world" so that the data means
something. Why?
Cheers,
