perf tools: Use "grep -E" instead of "egrep"
The latest version of grep claims the egrep is now obsolete so the build now contains warnings that look like: egrep: warning: egrep is obsolescent; using grep -E fix this up by moving the related file to use "grep -E" instead. sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/perf` Here are the steps to install the latest grep: wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz tar xf grep-3.8.tar.gz cd grep-3.8 && ./configure && make sudo make install export PATH=/usr/local/bin:$PATH Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Acked-by: Ian Rogers <irogers@google.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lore.kernel.org/lkml/1668762999-9297-1-git-send-email-yangtiezhu@loongson.cn Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |

perf beauty: Switch from GPL v2.0 to LGPL v2.1
The intention is to have this as a library, since it is not perf specific at all. I did the switch for the files where I'm the only contributor, with the exception of a few lines changed by Jiri Olsa.

perf trace beauty: Default header_dir to cwd to work without parms
Useful when checking the effects of header synchs for the files it uses
as a input to generate string tables, in retrospect this is how it
should've been done from day 1, not requiring the header_dir to be set
on the Makefile, will change everything later, so that the only parm,
common to all generators will be $(srctree) and $(beauty_outdir).
So, to see what it generates, just call it without any parameters:
$ tools/perf/trace/beauty/vhost_virtio_ioctl.sh
static const char *vhost_virtio_ioctl_cmds[] = {
[0x00] = "SET_FEATURES",
[0x01] = "SET_OWNER",
[0x02] = "RESET_OWNER",
[0x03] = "SET_MEM_TABLE",
[0x04] = "SET_LOG_BASE",
[0x07] = "SET_LOG_FD",
[0x10] = "SET_VRING_NUM",
[0x11] = "SET_VRING_ADDR",
[0x12] = "SET_VRING_BASE",
[0x13] = "SET_VRING_ENDIAN",
[0x14] = "GET_VRING_ENDIAN",
[0x20] = "SET_VRING_KICK",
[0x21] = "SET_VRING_CALL",
[0x22] = "SET_VRING_ERR",
[0x23] = "SET_VRING_BUSYLOOP_TIMEOUT",
[0x24] = "GET_VRING_BUSYLOOP_TIMEOUT",
[0x30] = "NET_SET_BACKEND",
[0x40] = "SCSI_SET_ENDPOINT",
[0x41] = "SCSI_CLEAR_ENDPOINT",
[0x42] = "SCSI_GET_ABI_VERSION",
[0x43] = "SCSI_SET_EVENTS_MISSED",
[0x44] = "SCSI_GET_EVENTS_MISSED",
[0x60] = "VSOCK_SET_GUEST_CID",
[0x61] = "VSOCK_SET_RUNNING",
};
static const char *vhost_virtio_ioctl_read_cmds[] = {
[0x00] = "GET_FEATURES",
[0x12] = "GET_VRING_BASE",
};
$
Or:
$ tools/perf/trace/beauty/sndrv_pcm_ioctl.sh
static const char *sndrv_pcm_ioctl_cmds[] = {
[0x00] = "PVERSION",
[0x01] = "INFO",

perf trace beautify ioctl: Beautify perf ioctl's 'cmd' arg
Also trying a new approach, using the copy of uapi/linux/perf_event.h we auto generate the string tables, then include it in the ioctl cmd beautifier. This way either the perf developers will add the new commands to the tools/ copy, like is happening with other areas of tools/include/ (bpf.h comes to mind), or we'll be notified when building perf that our copy drifted. E.g., looking at some of the perf ioctls issued by the 'perf test' test cases: # (perf trace -e perf_event_open,ioctl perf test) 2>&1 | egrep "(cmd: PERF_|perf_event_open)" 4: Read samples using the mmap interface : 348.811 ( 0.062 ms): perf/23351 perf_event_open(attr_uptr: 0x414a5e8, pid: 23351 (perf), group_fd: -1, flags: FD_CLOEXEC) = 3 348.878 ( 0.039 ms): perf/23351 perf_event_open(attr_uptr: 0x414a5e8, pid: 23351 (perf), cpu: 1, group_fd: -1, flags: FD_CLOEXEC) = 4 348.919 ( 0.036 ms): perf/23351 perf_event_open(attr_uptr: 0x414a5e8, pid: 23351 (perf), cpu: 2, group_fd: -1, flags: FD_CLOEXEC) = 5 348.958 ( 0.036 ms): perf/23351 perf_event_open(attr_uptr: 0x414a5e8, pid: 23351 (perf), cpu: 3, group_fd: -1, flags: FD_CLOEXEC) = 6 349.070 ( 0.046 ms): perf/23351 perf_event_open(attr_uptr: 0x414aa38, pid: 23351 (perf), group_fd: -1, flags: FD_CLOEXEC) = 7 349.120 ( 0.037 ms): perf/23351 perf_event_open(attr_uptr: 0x414aa38, pid: 23351 (perf), cpu: 1, group_fd: -1, flags: FD_CLOEXEC) = 8 349.161 ( 0.036 ms): perf/23351 perf_event_open(attr_uptr: 0x414aa38, pid: 23351 (perf), cpu: 2, group_fd: -1, flags: FD_CLOEXEC) = 9 349.201 ( 0.035 ms): perf/23351 perf_event_open(attr_uptr: 0x414aa38, pid: 23351 (perf), cpu: 3, group_fd: -1, flags: FD_CLOEXEC) = 10 349.306 ( 0.041 ms): perf/23351 perf_event_open(attr_uptr: 0x414b2d8, pid: 23351 (perf), group_fd: -1, flags: FD_CLOEXEC) = 11 349.611 ( 0.005 ms): perf/23351 ioctl(fd: 3<anon_inode:[perf_event]>, cmd: PERF_ID, arg: 0x7fff025999b8) = 0 349.619 ( 0.002 ms): perf/23351 ioctl(fd: 7<anon_inode:[perf_event]>, cmd: PERF_SET_OUTPUT, arg: 0x3 ) = 0 349.623 ( 0.002 ms): perf/23351 ioctl(fd: 7<anon_inode:[perf_event]>, cmd: PERF_ID, arg: 0x7fff025999b8) = 0 349.627 ( 0.002 ms): perf/23351 ioctl(fd: 11<anon_inode:[perf_event]>, cmd: PERF_SET_OUTPUT, arg: 0x3 ) = 0 349.630 ( 0.001 ms): perf/23351 ioctl(fd: 11<anon_inode:[perf_event]>, cmd: PERF_ID, arg: 0x7fff025999b8) = 0 <SNIP> 7: PERF_RECORD_* events & perf_sample fields : 647.150 ( 0.014 ms): perf/23354 perf_event_open(attr_uptr: 0x7fff02599920, pid: -1, cpu: 2, group_fd: -1, flags: FD_CLOEXEC) = 3 647.197 ( 0.076 ms): perf/23354 perf_event_open(attr_uptr: 0x414b478, pid: -1, group_fd: -1, flags: FD_CLOEXEC) = 3 647.289 ( 0.040 ms): perf/23354 perf_event_open(attr_uptr: 0x414b478, pid: -1, group_fd: -1, flags: FD_CLOEXEC) = 3 647.368 ( 0.011 ms): perf/23354 perf_event_open(attr_uptr: 0x414a5e8, pid: 23355 (perf), group_fd: -1, flags: FD_CLOEXEC) = 3 647.381 ( 0.005 ms): perf/23354 perf_event_open(attr_uptr: 0x414a5e8, pid: 23355 (perf), cpu: 1, group_fd: -1, flags: FD_CLOEXEC) = 4 647.387 ( 0.005 ms): perf/23354 perf_event_open(attr_uptr: 0x414a5e8, pid: 23355 (perf), cpu: 2, group_fd: -1, flags: FD_CLOEXEC) = 5 647.393 ( 0.004 ms): perf/23354 perf_event_open(attr_uptr: 0x414a5e8, pid: 23355 (perf), cpu: 3, group_fd: -1, flags: FD_CLOEXEC) = 7 648.026 ( 0.011 ms): perf/23354 ioctl(fd: 3<anon_inode:[perf_event]>, cmd: PERF_ENABLE) = 0 648.038 ( 0.002 ms): perf/23354 ioctl(fd: 4<anon_inode:[perf_event]>, cmd: PERF_ENABLE) = 0 648.042 ( 0.002 ms): perf/23354 ioctl(fd: 5<anon_inode:[perf_event]>, cmd: PERF_ENABLE) = 0 648.045 ( 0.002 ms): perf/23354 ioctl(fd: 7<anon_inode:[perf_event]>, cmd: PERF_ENABLE) = 0 <SNIP> 18: Breakpoint overflow signal handler : 2772.721 ( 0.017 ms): perf/23375 perf_event_open(attr_uptr: 0x7fff02599d20, pid: -1, cpu: 3, group_fd: -1, flags: FD_CLOEXEC) = 3 2772.748 ( 0.009 ms): perf/23375 perf_event_open(attr_uptr: 0x7fff02599e60, cpu: -1, group_fd: -1, flags: FD_CLOEXEC) = 3 2772.768 ( 0.002 ms): perf/23375 ioctl(fd: 3, cmd: PERF_RESET) = 0 2772.776 ( 0.008 ms): perf/23375 perf_event_open(attr_uptr: 0x7fff02599e60, cpu: -1, group_fd: -1, flags: FD_CLOEXEC) = 4 2772.788 ( 0.002 ms): perf/23375 ioctl(fd: 4, cmd: PERF_RESET) = 0 2772.791 ( 0.006 ms): perf/23375 perf_event_open(attr_uptr: 0x7fff02599e60, cpu: -1, group_fd: -1, flags: FD_CLOEXEC) = 5 2772.800 ( 0.001 ms): perf/23375 ioctl(fd: 5, cmd: PERF_RESET) = 0 2772.803 ( 0.005 ms): perf/23375 ioctl(fd: 3, cmd: PERF_ENABLE) = 0 2772.810 ( 0.004 ms): perf/23375 ioctl(fd: 4, cmd: PERF_ENABLE) = 0 2772.815 ( 0.004 ms): perf/23375 ioctl(fd: 5, cmd: PERF_ENABLE) = 0 <SNIP> Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-ahotwscqt080ae0ulu3zznh2@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> |
