Hi Buddies,
Currenty am using Xilinx ML310 FPGA board and am running
ppc linux on it.Now I want to profile kernel, like I want to run an
application and start kernel profiling and as application is finished I
want to stop kernel profiling and investigate where kernel is spending
more time.


I tried gprof for user space programs ...it was fine..but I
dont know how to do kernel space profiling .Do I need to add any
patches ?.


I tried to cross compile my ppc kernel with -pg
option but it says
"-pg and -fomit-frame-pointer are incompatible"


what does above line means exactly? does any one carried such tasks
before and could kindly direct me how to proceed now.


anticipating for your kind suggestions....thanks a lot..

Hoping some echoes


regards
Jaggu
