[Qemu-devel] [PATCH v8 06/11] Adding -d tb_stats to control TBStatistics collection:
-d tb_stats[[,level=(+all+jit+exec+time)][,dump_limit=]]
"dump_limit" is used to limit the number of dumped TBStats in
linux-user mode.
[all+jit+exec+time] control the profilling level used
by the TBStats. Can be used as follow:
-d tb_stats
-d tb_stats,level=jit+time
-d tb_stats,dump_limit=15
...
