[Qemu-devel] QEMU-user mode profiling

[maheen butt]

hi

I want to profile mips ELF with the help of QEMU so that I can find more time consuming portion of the code. does QEMU user mode emulation provide such feature? 

I did a small experiment. I configure QEMU with --enable-gprof and make

afterwards i gave following command

$qemu-mips hw_mips

where hw_mips is mips executable. 

a gmon.out file is generated as a result of above command  

I considered that it was same file generated by gprof  so I gave this command

$ gprof hw_mips

and got error "gprof: file `gmon.out' has unsupported version 16777216"

is gmon.out generated by qemu not same as gprof's gmon.out?
