RAM size and Lost RAM!
Hi all,
I'm running an embedded linux with kernel 2.4.21 on
a AU1000 (AMD processor with MIPS architecture)
My board comes with 16M of RAM, but I see:
# cat /proc/meminfo
total: used: free: shared: buffers: cached:
Mem: 13611008 8622080 4988928 0 0 3948544
Swap: 0 0 0
MemTotal: 13292 kB
MemFree: 4872 kB
MemShared: 0 kB
Buffers: 0 kB
Cached: 3856 kB
SwapCached: 0 kB
Active: 1060 kB
Inactive: 3864 kB
HighTotal: 0 kB
HighFree: 0 kB
LowTotal: 13292 kB
LowFree: 4872 kB
SwapTotal: 0 kB
SwapFree: 0 kB
Any idea of where are the 2.5M of missing RAM: are they
silently used by kernel, of did I misconfigure something?
in my PC, 512M RAM I see
[giammy@pgr12 ~]$ cat /proc/meminfo
MemTotal: 514664 kB
....
This made me suspect I'm missing osmethin in the AMD :-(
thanx

I don't know this board. But if it is a board with onboard graphic with
shared ram. It could be the videoram that you are missing.
