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 ----------------------------------------------------------------------- <4>Memory: 4876k/6144k available (801k kernel code, 1268k reserved, 69k data, 60k init) ... <4>Freeing unused kernel memory: 60k freed ----------------------------------------------------------------------- /proc # cat iomem 00000000-005fffff : System RAM 00000000-00000fff : ??????????? 4096 (added by hand) 00001000-000ca687 : Kernel code 824968 000ca688-000db99f : ??????????? 70424 (added by hand) 000db9a0-000ed033 : Kernel data 71316 ------ 970804 /proc # cat meminfo total: used: free: shared: buffers: cached: Mem: 5046272 1392640 3653632 0 16384 598016 Swap: 0 0 0 MemTotal: 4928 kB MemFree: 3568 kB MemShared: 0 kB Buffers: 16 kB Cached: 584 kB Active: 600 kB Inact_dirty: 0 kB Inact_clean: 0 kB Inact_target: 12 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 4928 kB LowFree: 3568 kB SwapTotal: 0 kB 6291456 (6 MB allocated to kernel in prom.c) - 5046272 (Total memory in use) --------- 1245184 1245184 - 970804(Kernel memory) = 274380 I can not account for this memory. -- Scott A.
