Ahmed Karaman 5c362ccfde scripts/performance: Add topN_callgrind.py script ... Python script that prints the top N most executed functions in QEMU using callgrind. Syntax: topN_callgrind.py [-h] [-n] <number of displayed top functions> -- \ <qemu executable> [<qemu executable options>] \ <target executable> [<target execurable options>] [-h] - Print the script arguments help message. [-n] - Specify the number of top functions to print. - If this flag is not specified, the tool defaults to 25. Example of usage: topN_callgrind.py -n 20 -- qemu-arm coulomb_double-arm Example Output: No. Percentage Function Name Source File ---- --------- ------------------ ------------------------------ 1 24.577% 0x00000000082db000 ??? 2 20.467% float64_mul <qemu>/fpu/softfloat.c 3 14.720% float64_sub <qemu>/fpu/softfloat.c 4 13.864% float64_add <qemu>/fpu/softfloat.c 5 4.876% helper_mulsd <qemu>/target/i386/ops_sse.h 6 3.767% helper_subsd <qemu>/target/i386/ops_sse.h 7 3.549% helper_addsd <qemu>/target/i386/ops_sse.h 8 2.185% helper_ucomisd <qemu>/target/i386/ops_sse.h 9 1.667% helper_lookup_tb_ptr <qemu>/include/exec/tb-lookup.h 10 1.662% f64_compare <qemu>/fpu/softfloat.c 11 1.509% helper_lookup_tb_ptr <qemu>/accel/tcg/tcg-runtime.c 12 0.635% helper_lookup_tb_ptr <qemu>/include/exec/exec-all.h 13 0.616% float64_div <qemu>/fpu/softfloat.c 14 0.502% helper_pand_xmm <qemu>/target/i386/ops_sse.h 15 0.502% float64_mul <qemu>/include/fpu/softfloat.h 16 0.476% helper_lookup_tb_ptr <qemu>/target/i386/cpu.h 17 0.437% float64_compare_quiet <qemu>/fpu/softfloat.c 18 0.414% helper_pxor_xmm <qemu>/target/i386/ops_sse.h 19 0.353% round_to_int <qemu>/fpu/softfloat.c 20 0.347% helper_cc_compute_all <qemu>/target/i386/cc_helper.c Signed-off-by: Ahmed Karaman <ahmedkhaledkaraman@gmail.com> Signed-off-by: Aleksandar Markovic <aleksandar.qemu.devel@gmail.com> Reviewed-by: Aleksandar Markovic <aleksandar.qemu.devel@gmail.com> Message-Id: <20200626164546.22102-3-ahmedkhaledkaraman@gmail.com>		2020-06-27 20:07:59 +02:00
