1# See docs/devel/tracing.rst for syntax documentation. 2# 3# This file is processed by the tracetool script during the build. 4# 5# To add a new trace event: 6# 7# 1. Choose a name for the trace event. Declare its arguments and format 8# string. 9# 10# 2. Call the trace event from code using trace_##name, e.g. multiwrite_cb() -> 11# trace_multiwrite_cb(). The source file must #include "trace.h". 12# 13# Format of a trace event: 14# 15# [disable] <name>(<type1> <arg1>[, <type2> <arg2>] ...) "<format-string>" 16# 17# Example: g_malloc(size_t size) "size %zu" 18# 19# The "disable" keyword will build without the trace event. 20# 21# The <name> must be a valid as a C function name. 22# 23# Types should be standard C types. Use void * for pointers because the trace 24# system may not have the necessary headers included. 25# 26# The <format-string> should be a sprintf()-compatible format string. 27 28# cpu.c 29breakpoint_insert(int cpu_index, uint64_t pc, int flags) "cpu=%d pc=0x%" PRIx64 " flags=0x%x" 30breakpoint_remove(int cpu_index, uint64_t pc, int flags) "cpu=%d pc=0x%" PRIx64 " flags=0x%x" 31breakpoint_singlestep(int cpu_index, int enabled) "cpu=%d enable=%d" 32 33# job.c 34job_state_transition(void *job, int ret, const char *legal, const char *s0, const char *s1) "job %p (ret: %d) attempting %s transition (%s-->%s)" 35job_apply_verb(void *job, const char *state, const char *verb, const char *legal) "job %p in state %s; applying verb %s (%s)" 36job_completed(void *job, int ret) "job %p ret %d" 37 38# job-qmp.c 39qmp_job_cancel(void *job) "job %p" 40qmp_job_pause(void *job) "job %p" 41qmp_job_resume(void *job) "job %p" 42qmp_job_complete(void *job) "job %p" 43qmp_job_finalize(void *job) "job %p" 44qmp_job_dismiss(void *job) "job %p" 45
