Subject: Top 128MB of virtual address space
Date: Thu, 27 Feb 2003 16:50:42 -0500 [thread overview]
Message-ID: <3E5E8832.688AE0CB@watson.ibm.com> (raw)
For linux running on an Intel machine without PAE, the top 128MB of
virtual address space:
If
PKMAP_BASE = FE000000
and
FIXADDR_START=FFF55000
That leaves a 32MB area. I believe the permanent highmem mappings are
1024 pages so that leaves 28MB of address space. What is this space
used for if anything?
