Can anybody help me on LMBench 'Context switching timer' (lat_ctx)
test. In manual, it is mentioned "lat_ctx measures context switching time
for any reasonable number of processes of any reasonable size".
By default , lmbench tests 'context switching time' for the process
size 2k, 4k, .. upto 64 k with various number of process combinations (ie.
number of process as 2,4,6, upto 96 processes) .
But If I try increasing the process size (ie, 2mb, 4mb ) I am not
getting any results or error. on other lesser sizes , I am able to see the
results as the no.of processes and time taken to switch between them. I have
tested this on ARMv6 board having 128 mb ram and in a normal Pentium 4 PC
having 1Gb memory.
