[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

I have one question, if I do cat /proc/meminfo

and do sum of VmallocTotal   (114680 kB)=VmallocUsed(4440
kB)+VmallocChunk(109804 kB)
is not equal, there is difference. why it is there ? is it related for
ioremap ?.
2. Is MemTotal= VmallocTotal + Other parts ?
