Hi, This patch implements a pretty print feature to the hypercall counters. I added an option -p so it would be easier to see how many times each hypercall was called. The function of option -f is left untouched. The result is as the attachment. Reference: http://lists.xensource.com/archives/html/xen-devel/2006-08/msg01324.html Signed-off-by: Yoshihiko Yaegashi <y.yaegashi@xxxxxxxxxxxxxx> Signed-off-by: Ken Hironaka <kenny@xxxxxxxxxxxxxxxxxxxxxxxx> Thanks, Yaegashi diff -r b21246720fde -r 986fd62fbfda tools/misc/xenperf.c
