Detailed Description
This structure has the major information of the each process.
Field Documentation
◆ cgroup_id
| char tr_info::cgroup_id[NAME_MAX] |
Current cgroup name. This value must be unique.
◆ device
| char tr_info::device[NAME_MAX] |
Device name.(e.g. sda, sdb) WARNING, you must not contain the /dev/
◆ global_config
| void* tr_info::global_config |
runner's global_config information
◆ iosize
| unsigned int tr_info::iosize |
I/O size of task.
◆ mqid
| int tr_info::mqid |
Message Queue ID which is shared between parent and child.
◆ next
◆ nr_thread
| unsigned int tr_info::nr_thread |
The number of thread per task.
◆ pid
| pid_t tr_info::pid |
Contain the PID of the child's process which is created by parent's fork command. Usually, the child process has this value to 0.
◆ ppid
| pid_t tr_info::ppid |
Contain the parent's PID. Usually, parent's process has this value to 0
◆ prefix_cgroup_name
| char tr_info::prefix_cgroup_name[NAME_MAX] |
Cgroup prefix which will be made inside of /sys/fs/cgroup/blkio
◆ q_depth
| unsigned int tr_info::q_depth |
Queue depth of the benchmark program. Generally, this value is equal to the number of cores.
◆ scheduler
| char tr_info::scheduler[NAME_MAX] |
Scheduler name(e.g. none, bfq, kyber).
◆ semid
| int tr_info::semid |
Semaphore ID which is shared betweeen parent and child.
◆ shmid
| int tr_info::shmid |
Shared Memory ID which is shared between parent and child.
◆ time
| unsigned int tr_info::time |
Total execution time of benchmark program. (seconds)
◆ trace_data_path
| char tr_info::trace_data_path[PATH_MAX] |
trace-replay trace data path
◆ trace_repeat
| unsigned int tr_info::trace_repeat |
The number of repeat of task.
◆ trace_replay_path
| char tr_info::trace_replay_path[PATH_MAX] |
trace-replay binary path
◆ utilization
| unsigned int tr_info::utilization |
utilization of task.
◆ weight
| unsigned int tr_info::weight |
You can use only on BFQ scheduler.
◆ wss
| unsigned int tr_info::wss |
Working set size.
