Subject: Accounting for all memory.
Date: Thu, 02 May 2002 14:50:10 -0500 [thread overview]
Message-ID: <3CD19872.63FBF81E@cotw.com> (raw)
I am trying to understand memory usage on my system.
NEC VR5432, mipsel, 2.4.5 kernel
Does slab info appear in "used:" column of /proc/meminfo?
What the holes "??????" in /proc/iomem are used for?
I can not account for all of the "1268k reserved memory.
Thanks in advance,
Scott
