# To add a new trace event:
|
|
|
|
|
#
|
|
|
|
|
# 1. Choose a name for the trace event. Declare its arguments and format
|
|
|
|
|
# string.
|
|
|
|
|
#
|
|
|
|
|
# 2. Call the trace event from code using trace_##name, e.g. multiwrite_cb() ->
|
|
|
|
|
# trace_multiwrite_cb(). The source file must #include "trace.h".
|

trace: [trivial] Statically enable all guest events
The existing optimizations makes it feasible to have them available on all
builds.
Some quick'n'dirty numbers with 400.perlbench (SPECcpu2006) on the train input
(medium size - suns.pl) and the guest_mem_before event:
* vanilla, statically disabled
real 0m2,259s
user 0m2,252s
sys 0m0,004s
* vanilla, statically enabled (overhead: 2.18x)
real 0m4,921s
user 0m4,912s
sys 0m0,008s
* multi-tb, statically disabled (overhead: 0.99x) [within noise range]
real 0m2,228s
user 0m2,216s
sys 0m0,008s
* multi-tb, statically enabled (overhead: 0.99x) [within noise range]
real 0m2,229s
user 0m2,224s
sys 0m0,004s
Now enabling all events when booting an ARM system that immediately shuts down
(https://lists.gnu.org/archive/html/qemu-devel/2017-06/msg04085.html):
* vanilla, statically disabled
real 0m32,153s
user 0m31,276s
sys 0m0,108s
* vanilla, statically enabled (overhead: 1.35x)
real 0m43,507s
user 0m42,680s
sys 0m0,168s
* multi-tb, statically disabled (overhead: 1.03x)
real 0m32,993s
user 0m32,516s
sys 0m0,104s
* multi-tb, statically enabled (overhead: 1.00x) [within noise range]
real 0m32,110s
user 0m31,176s
sys 0m0,156s
And finally enabling all events using Emilio's dbt-bench
(where orig == vanilla, new == multi-tb):
