I'm using framework RTDM to develop my driver on embedded system mpc5200
(kernel 188.8.131.52 (powerpc arch) - xenomai 2.4.3).
I've need to use rtdm_mmap_to_user() to share a kmalloc() kernel memory
For this, I'm using the example in
Running a similar example I've discovered a problem in kmalloc remapping.
The only way that I've found, to make remapping correctly, is to
allocate an entire kernel mem page with __get_freepage() instead of
I think that could be a bug in powerpc arch.
what do you think about?
