# Trace events for debugging and performance instrumentation

|
|
|
|
# This file is processed by the tracetool script during the build.
|
|
|
|
#
|
|
|
|
# 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".
|
|
|
|
#
|
|
|
|
# Format of a trace event:
|
|
|
|
#
|
2010-05-24 12:32:09 +02:00
|
|
|
# [disable] <name>(<type1> <arg1>[, <type2> <arg2>] ...) "<format-string>"

2010-05-24 12:32:09 +02:00

# The <name> must be a valid as a C function name.

monitor: Simplify event throttling
The event throttling state machine is hard to understand. I'm not
sure it's entirely correct. Rewrite it in a more straightforward
manner:
State 1: No event sent recently (less than evconf->rate ns ago)
Invariant: evstate->timer is not pending, evstate->qdict is null
On event: send event, arm timer, goto state 2
State 2: Event sent recently, no additional event being delayed
Invariant: evstate->timer is pending, evstate->qdict is null
On event: store it in evstate->qdict, goto state 3
On timer: goto state 1
State 3: Event sent recently, additional event being delayed
Invariant: evstate->timer is pending, evstate->qdict is non-null
On event: store it in evstate->qdict, goto state 3
On timer: send evstate->qdict, clear evstate->qdict,
arm timer, goto state 2

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):
NBench score; higher is better

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):
