SubjectMerge ftrace data of host and guest
Hi,

I am adding trace data of host and guest using trace-merge script .

https://15351300108708232970.googlegroups.com/attach/66533d7b41eed0b/trace-merge.pl?part=0.1&view=1&vt=ANaJVrHKDEwmNeLGDINH0B5Ud4OIUrfQ2_2w2jo08nJujH7Oc9facKD3ckT2RbCiHkRAfnYxmZnBF7qi0SeMZr2IMsPBDNjgrYkblCRkmgSk2PryLVsGe5g

Data after merging :

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
<idle>-0 [001] 4401.096899: net_dev_queue:
dev=eth0 skbaddr=0xffff88001a9fe000 len=98
<idle>-0 [001] 4401.096935: net_dev_xmit:
dev=eth0 skbaddr=0xffff88001a9fe000 len=98 rc=0
<idle>-0 [001] 4401.097277: netif_receive_skb:
dev=eth0 skbaddr=0xffff88001a9fe800 len=84
<idle>-0 [001] 4401.097309: net_dev_queue:

dev=eth0 skbaddr=0xffff88001a9fe000 len=98 rc=0
<idle>-0 [001] 4401.097830: netif_receive_skb:
dev=eth0 skbaddr=0xffff88001a9fe800 len=84
<idle>-0 [001] 4401.097843: net_dev_queue:
dev=eth0 skbaddr=0xffff88001a9fea00 len=98


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