Hello all,
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?
Kindly clarify
Thanks in advance
Heramba
