Commit d9bb58e510 ("tcg: move tcg related files into accel/tcg/
subdirectory") introduced accel/tcg/trace-events, so we don't
need to use the root trace-events anymore.

# 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:
|
|
#
|
|
# [disable] <name>(<type1> <arg1>[, <type2> <arg2>] ...) "<format-string>"
|
|
#
|
|
# Example: g_malloc(size_t size) "size %zu"
|
|
#
|
|
# The "disable" keyword will build without the trace event.
|
|
#
|
|
# The <name> must be a valid as a C function name.
|
|
#
|
|
# Types should be standard C types. Use void * for pointers because the trace
|
|
# system may not have the necessary headers included.
|
|
#
|
|
# The <format-string> should be a sprintf()-compatible format string.
