Hi all,
I would be very thankful if anyone confirms my understanding of mmap.
I am using mmap to attach a device buffer into the process virtual address space. My understanding is that there will not be a kernel copy of the device buffer.
So writing into the process address space is like writing into the device buffer directly without a memory copy.
Am I correct in my understanding.
Thanks in advance for your help.
Regards,
Prodyut.
