Subject: [PATCH 0/4] ftrace, workqueuetrace: Add worklet informationame
Date: Mon, 20 Apr 2009 14:42:11 +0800 [thread overview]
Message-ID: <49EC1943.8080606@cn.fujitsu.com> (raw)
In-Reply-To: <20090415141250.AC46.A69D9226@jp.fujitsu.com>
Hello,
To make workqueuetrace support per-worklet's time mesurement(max execution,
latecy), workqueue trace need to support per-worklet's stat information first.
This patchset add them.
Before patch:
# cat [debugfs]/tracing/trace_stat/workqueues
# CPU INSERTED EXECUTED NAME
# | | | |
0 589 589 events/0
0 0 0 cpuset
0 656 656 khelper
0 0 0 netns
0 809 809 kblockd/0
0 0 0 kacpid
0 0 0 kacpi_notify
0 0 0 ata/0
0 0 0 ata_aux
0 0 0 ksuspend_usbd
0 0 0 aio/0
0 0 0 nfsiod
0 0 0 crypto/0
0 0 0 kpsmoused
0 0 0 kstriped
0 0 0 kondemand/0
0 0 0 usbhid_resumer
0 21 21 rpciod/0
After patch:
# cat [debugfs]/tracing/trace_stat/workqueues
# CPU INSERTED EXECUTED TASKNAME:PID
# | | | `-WORKFUNC
# | | | |
0 273 273 events/0:5

0 4 4 |-check_corruption+0x0/0x2c
0 1 1 |-power_supply_changed_work+0x0/0x3c
0 6 6 |-console_callback+0x0/0x145
0 229 229 |-vmstat_update+0x0/0x33

0 0 0 netns:11
0 1818 1818 kblockd/0:13
0 1115 1115 |-blk_unplug_work+0x0/0x1e
0 703 703 `-cfq_kick_queue+0x0/0x2f
0 0 0 kacpid:412
0 0 0 kacpi_notify:415
0 0 0 ata/0:463
0 0 0 ata_aux:509
0 0 0 ksuspend_usbd:515
0 0 0 aio/0:717
0 0 0 nfsiod:764
0 0 0 crypto/0:785
0 0 0 kpsmoused:1141
0 0 0 kstriped:1248
0 0 0 kondemand/0:1259
0 0 0 usbhid_resumer:1264
0 20 20 rpciod/0:1333
0 1 1 |-xs_tcp_connect_worker4+0x0/0x1b
0 19 19 `-xs_udp_connect_worker4+0x0/0x130
After this step, we'll begin to add worklet time mesurement support to
workqueuetrace.
Thanks
Zhaolei
