Subject: [dpdk-dev] [PATCH v2] Add support for pthread_setname
Date: Tue, 28 Jul 2015 17:50:45 -0700	[thread overview]
Message-ID: <1438131045-3069-1-git-send-email-rkerur@gmail.com> (raw)

This patch adds support for pthread_setname_np on Linux
and pthread_set_name_np on FreeBSD to aid in debugging by
identifying DPDK threads by it name. Following is the sample
output on Linux and FreeBSD.

On Linux:
rkerur@dpdk-ubuntu# ps H -C testpmd -o 'pid tid cmd comm'
  PID   TID CMD                         COMMAND
32590 32590 x86_64-native-linuxapp-gcc/ testpmd
32590 32591 x86_64-native-linuxapp-gcc/ eal-intr-thread
32590 32592 x86_64-native-linuxapp-gcc/ lcore-slave-1
32590 32593 x86_64-native-linuxapp-gcc/ lcore-slave-2
32590 32594 x86_64-native-linuxapp-gcc/ lcore-slave-3
32590 32595 x86_64-native-linuxapp-gcc/ lcore-slave-4
32590 32596 x86_64-native-linuxapp-gcc/ lcore-slave-5
32590 32597 x86_64-native-linuxapp-gcc/ lcore-slave-6
32590 32598 x86_64-native-linuxapp-gcc/ lcore-slave-7

On FreeBSD:
rkerur@dpdk-bsd:~ # procstat -t 28630
  PID    TID COMM             TDNAME           CPU  PRI STATE   WCHAN
28630 100066 cmdline          -                  0  133 sleep   ttyin
28630 100170 cmdline          lcore-slave-1      1  152 sleep   piperd
28630 100171 cmdline          lcore-slave-2      2  152 sleep   piperd
28630 100172 cmdline          lcore-slave-3      3  152 sleep   piperd
