Hi. I'm having some issues with the control flow view.
2.6.36 lttng enabled kernel, svn r27050 of the plugin. I ran the following steps in single user with maxcpus=1 cc -o open-write open-write.c lttctl -C -p <path> traceK ./open-write foo lttctl -D traceK This generated what seems to be a good trace. lttv -m textDump -t <path> | grep "syscall_.*open-write" shows all the expected syscalls. My issue is that the eclipse plugin doesn't show what I expected it would. Selecting the task in the control view and iterating the events with NextEv, all I see is: kernel/0/process_fork kernel/0/sched_schedule kernel/0/syscall_entry [then nothing] If I adjust the trace to 206.000 I can see two gantt entries for open-write, one WAIT and another for SYSCALL but the later states that the stop time is undefined which is consistent with it failing to see a syscall_exit event. Trace is at: http://ftp.suse.com/pub/people/tonyj/temp/trace.tar.bz2 Tony ---- open-write.c ---- #include <stdio.h> #include <string.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> int main(int argc, char *argv[]) { int fd, cnt; pid_t pid=getpid(); char *s="this is a sample string!"; char buf[512]; if (argc != 2) { fprintf(stderr, "usage: %s filename\n", argv[0]); return 1; } fd = open(argv[1], O_RDWR|O_CREAT, 0600); if (fd == -1) { perror("open"); return 1; } if (write(fd, s, strlen(s)) != strlen(s)) { perror("write"); return 1; } lseek(fd, SEEK_SET, 0); cnt=read(fd, buf, sizeof(buf)); buf[cnt] = 0; printf("%u: %s\n", pid, buf); close(fd); } ---------------------- _______________________________________________ linuxtools-dev mailing list linuxtools-dev@eclipse.org https://dev.eclipse.org/mailman/listinfo/linuxtools-dev
