3MB RAM missing from 32MB total (see /proc/meminfo) #17

Closed GoogleCodeExporter closed 9 years ago

Looks like there are three 3MB missing from the total memory reported in
/proc/meminfo. Check it out and see what are they being used for (and
reclaim them if possible).

Isn't this memory reserved for the IPU? See arch/mips/jz4740/proc.c

There WERE 4MB reserved for the IPU. I modified the kernel to allow optiona 
disable
of this memory and it is disabled in the default kernel configuration.

(Will be needed when we start with video stuff... but meanwhile we get some 
memory back)

The missing memory is used by the kernel code.
