As there is no -v option for perf kvm, the all debug message for perf kvm will nerver be printed out to user. Example: # perf kvm --guestmount /tmp/guestmount/ record -a Not enough memory for reading perf file header It is confusing message for newbies such as me. With this patch applied, we can use -v option to get the detail. Example: # perf kvm --guestmount /tmp/guestmount/ record -a -v Can't access file /tmp/guestmount//15069/proc/kallsyms Not enough memory for reading perf file header Signed-off-by: Dongsheng Yang <yangds.fnst@cn.fujitsu.com> Cc: David Ahern <dsahern@gmail.com> Link: http://lkml.kernel.org/r/1386609311-23889-1-git-send-email-yangds.fnst@cn.fujitsu.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
