Memory ZONES in PPC boardam 16.10.2011 05:42:17 von Nanda
We have PPC board which runs on linux kernel. When I looked at dmesg,
the memory ZONES were divided as below
768MB for ZONE_DMA
256MB for ZONE_HIGHMEM
ZONE_NORMAL is not present.
Now what does this mean? Is that kernel space entirely mapped to
ZONE_DMA? Does user process get only 256MB of physical memory? I am
pretty much confused about these zones.
Is this particular to only PPC architecture?
Thanks in advance
