Subject: [PATCH 0/3] perf trace powerpc: Remove libaudit dependency for syscalls
Date: Mon, 29 Jan 2018 14:04:14 +0530 [thread overview]
Message-ID: <20180129083417.31240-1-ravi.bangoria@linux.vnet.ibm.com> (raw)
This is almost identical set of patches recently done for s390.
With this, user can run perf trace without libaudit on powerpc
as well. Ex,
$ make
... libaudit: [ OFF ]
$ ./perf trace ls
0.221 ( 0.005 ms): ls/43330 open(filename: 0xac1e2778, flags: CLOEXEC ) = 3
0.227 ( 0.003 ms): ls/43330 read(fd: 3, buf: 0x3ffff9c4d678, count: 832 ) = 832
0.233 ( 0.002 ms): ls/43330 fstat(fd: 3, statbuf: 0x3ffff9c4d4b0 ) = 0
...
$ ./perf trace -e "open*" ls
0.000 ( 0.014 ms): ls/43342 open(filename: 0x793d8978, flags: CLOEXEC ) = 3
0.038 ( 0.006 ms): ls/43342 open(filename: 0x793f2778, flags: CLOEXEC ) = 3
...
