| |
I still need some help with mapping buffers in kernel space to user space. I've looked at the soundrivers, but I'm still not clear on a couple of issues.
If I allocate memory in kernel with vmalloc, this will be locked in RAM correct? The buffer is NOT used for DMA, so vmalloc allocated memory should be OK.
Do I have to create a VMA structure on my own or something similar? What are functions are involved in the remapping?
I the buffer that I want to remap is part of a network driver.
I'm still pretty clueless as you can see :-( If somebody could please explain a few more steps that would be really great!!
Thanks a lot,
Olaf
P.S. please also send an email to me, since I currently can't handle the high volume mailing list
