Subject: Tell me about ZONE_DMA
Date: Wed, 05 Jul 2000 16:13:52 -0500 [thread overview]
Message-ID: <20000705212704Z131198-21004+106@kanga.kvack.org> (raw)
I'm trying to understand the differences between the three zones, ZONE_DMA,
ZONE_NORMAL,and ZONE_HIGHMEM. I've searched the source code (I'm getting pretty
good at understanding the kernel memory allocator), but I can't figure out what
physical regions of memory belong to each zone. Where is that determined?
Also, I get this eerie feeling that it's possible for a physical page to exist
in more than one zone. Is that true?
