Re: [Crash-utility] Issues with kmem -i

On executing kmem -i over dump we are seeing these results crash> kmem -i PAGES TOTAL PERCENTAGE TOTAL MEM 128778 503 MB ---- FREE 44244 172.8 MB 34% of TOTAL MEM USED 84534 330.2 MB 65% of TOTAL MEM SHARED 45690 178.5 MB 35% of TOTAL MEM BUFFERS 4371 17.1 MB 3% of TOTAL MEM CACHED 51358 200.6 MB 39% of TOTAL MEM SLAB 0 0 0% of TOTAL MEM TOTAL HIGH 0 0 0% of TOTAL MEM This is due to the fact that o mi->get_slabs field is turning out to be zero in dump_mem_map() function. This is happening as vt->PG_slab field is not getting updated with value(10 in this case) in vm_init(). This is happening as pte field is taken from page structure. o Probable solutions: Hard code value vt->PG_slab ??

o The output is breaking as totalhigh_pages is coming out zero, So part of code in function dump_kmeminfo() pct = freehighmem_pages ? (freehighmem_pages * 100)/totalhigh_pages : 0; Cause Arithmetic calculation error. Still looking into the problem.
