Subject: What are the default VMA maps for linux on PPC32?
Date: Sun, 25 Jan 2009 14:08:51 -0500 [thread overview]
Message-ID: <497CB8C3.5080907@gmail.com> (raw)
Is there a good source that lists the standard virtual address mappings
of the various components of linux? I know the kernel starts at
0xC000_0000 and user apps start at 0x1000_0000, but things like shared
objects are much less clear. For example, the smap entry for my ntpd
process shows two distinct areas of usage: ~0xf000_0000 and
~0x3000_0000, but I have no idea what's where and why. Can anyone shed
some light on this? Thanks.
Matt
