Message-ID: <CAGfiMvCLgdaACWuUJAWecaLP9cSZRLFzzWgNGoiZTidT9m60cg@mail.gmail.com> (raw)
Hi,
I am adding trace data of host and guest using trace-merge script .

I think it is not desired output . Ths script is written for diffrent
format .ftrace format is ( trace-cmd report command generates) :
version = 6
CPU 0 is empty
cpus=2
<idle>-0 [001] 4401.096833: netif_receive_skb:
dev=eth0 skbaddr=0xffff88001ed8fc00 len=84

Can you let me know I there is any other method to merge the traces or
any further changes in the script
