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# dma-helpers.c 34dma_blk_io(void *dbs, void *bs, int64_t offset, bool to_dev) "dbs=%p bs=%p offset=%" PRId64 " to_dev=%d" 35dma_aio_cancel(void *dbs) "dbs=%p" 36dma_complete(void *dbs, int ret, void *cb) "dbs=%p ret=%d cb=%p" 37dma_blk_cb(void *dbs, int ret) "dbs=%p ret=%d" 38dma_map_wait(void *dbs) "dbs=%p" 39 40# exec.c 41find_ram_offset(uint64_t size, uint64_t offset) "size: 0x%" PRIx64 " @ 0x%" PRIx64 42find_ram_offset_loop(uint64_t size, uint64_t candidate, uint64_t offset, uint64_t next, uint64_t mingap) "trying size: 0x%" PRIx64 " @ 0x%" PRIx64 ", offset: 0x%" PRIx64" next: 0x%" PRIx64 " mingap: 0x%" PRIx64 43ram_block_discard_range(const char *rbname, void *hva, size_t length, bool need_madvise, bool need_fallocate, int ret) "%s@%p + 0x%zx: madvise: %d fallocate: %d ret: %d" 44 45# accel/tcg/cputlb.c 46memory_notdirty_write_access(uint64_t vaddr, uint64_t ram_addr, unsigned size) "0x%" PRIx64 " ram_addr 0x%" PRIx64 " size %u" 47memory_notdirty_set_dirty(uint64_t vaddr) "0x%" PRIx64 48 49# gdbstub.c 50gdbstub_op_start(const char *device) "Starting gdbstub using device %s" 51gdbstub_op_exiting(uint8_t code) "notifying exit with code=0x%02x" 52gdbstub_op_continue(void) "Continuing all CPUs" 53gdbstub_op_continue_cpu(int cpu_index) "Continuing CPU %d" 54gdbstub_op_stepping(int cpu_index) "Stepping CPU %d" 55gdbstub_op_extra_info(const char *info) "Thread extra info: %s" 56gdbstub_hit_watchpoint(const char *type, int cpu_gdb_index, uint64_t vaddr) "Watchpoint hit, type=\"%s\" cpu=%d, vaddr=0x%" PRIx64 "" 57gdbstub_hit_internal_error(void) "RUN_STATE_INTERNAL_ERROR" 58gdbstub_hit_break(void) "RUN_STATE_DEBUG" 59gdbstub_hit_paused(void) "RUN_STATE_PAUSED" 60gdbstub_hit_shutdown(void) "RUN_STATE_SHUTDOWN" 61gdbstub_hit_io_error(void) "RUN_STATE_IO_ERROR" 62gdbstub_hit_watchdog(void) "RUN_STATE_WATCHDOG" 63gdbstub_hit_unknown(int state) "Unknown run state=0x%x" 64gdbstub_io_reply(const char *message) "Sent: %s" 65gdbstub_io_binaryreply(size_t ofs, const char *line) "0x%04zx: %s" 66gdbstub_io_command(const char *command) "Received: %s" 67gdbstub_io_got_ack(void) "Got ACK" 68gdbstub_io_got_unexpected(uint8_t ch) "Got 0x%02x when expecting ACK/NACK" 69gdbstub_err_got_nack(void) "Got NACK, retransmitting" 70gdbstub_err_garbage(uint8_t ch) "received garbage between packets: 0x%02x" 71gdbstub_err_overrun(void) "command buffer overrun, dropping command" 72gdbstub_err_invalid_repeat(uint8_t ch) "got invalid RLE count: 0x%02x" 73gdbstub_err_invalid_rle(void) "got invalid RLE sequence" 74gdbstub_err_checksum_invalid(uint8_t ch) "got invalid command checksum digit: 0x%02x" 75gdbstub_err_checksum_incorrect(uint8_t expected, uint8_t got) "got command packet with incorrect checksum, expected=0x%02x, received=0x%02x" 76 77# job.c 78job_state_transition(void *job, int ret, const char *legal, const char *s0, const char *s1) "job %p (ret: %d) attempting %s transition (%s-->%s)" 79job_apply_verb(void *job, const char *state, const char *verb, const char *legal) "job %p in state %s;
