Suppose there are $2$ level cache.  If there are $L_{1}$ and $L_{2}$ are $2$ level cache, if both have some miss rate, then still why we need miss penalty for cache in both levels?

As we always search T1 then only T2 the MM i.e why

Teff=H1*T1+(1-H1)H2*T2+(1-H1)*(1-H2)*M    [ provided Pralell searching is used]
