Hi, can anyone help me?
from perfetto.
Your file begins as follows:
TRACE:
# tracer: nop
#
# entries-in-buffer/entries-written: 41390/41390 #P:8
#
# _-----=> irqs-off
# / _----=> need-resched
# | / _---=> hardirq/softirq
# || / _--=> preempt-depth
# ||| / delay
# TASK-PID TGID CPU# |||| TIMESTAMP FUNCTION
# | | | | |||| | |

<idle>-0 (-----) [002] d..1 223230.807329: cpu_idle: state=3 cpu_id=2
<idle>-0 (-----) [003] .n.1 223230.807422: cpu_idle: state=4294967295 cpu_id=3
<idle>-0 (-----) [003] d..1 223230.807476: cpu_idle: state=3 cpu_id=3
<idle>-0 (-----) [000] d..1 223230.807481: cpu_idle: state=0 cpu_id=0
The issue is the first line:
TRACE:
If you delete this the trace works fine.
The line that causes the issue is here:
When we see
TRACE:
we expect the file to be in .ctrace
format, which is to say a .zip file. In fact your trace is not compressed so we should instead use the kSystraceTraceType parser. This can happen if someone manually uses atrace without the compression option -z
. We should amend the trace detection logic to take this situation into account.from perfetto.
@chromy Many many thx~
