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 giammy

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.
