Hi,
    Previously I have run oprofile on linux-mips and have two
questions about it.
    It seems that oprofile does not support callgraph on linux-mips
currently, since there is no
backtrace function in oprofile kernel module for mips target.
    Is it possible or easy to support callgraph on mips target? If I
am right, it's some kind of
difficult to calculate stack frames of interrupted user space
programs, at least for O32 ABI.

Any tips would be appriciated. thanks.
