perf map: Optimize maps__fixup_overlappings() (2018-08-08 15:56:00 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf annotate: (Jiri Olsa)
- Show percentage based on global or local hits or period, adding hotkeys ('p':
local/global, 'b': hit/period, use 'h' to see all hotkeys in the TUI) to
toggle those modes in the TUI, as well as a command line to select that, i.e.
perf report/annotate --percent-type global-period,local-period,global-hits,local-hits
to help understand the impact an annotated line has globally or just on the
function's total number of hits or its total period.
Try using it from the dynamic annotation interface from 'perf top', i.e.
fire up 'perf top', then press 'a' on a kernel function then try pressing 'p'
to see, dynamicly, the global/local percentage for the lines with samples.
This was based on a suggestion made by Stephane Eranian.
perf trace: (Arnaldo Carvalho de Melo)
- Process syscalls:sys_enter_SYSCALLNAME tracepoints using the strace-like
beautifiers used with raw_syscalls:sys_enter, paving the way to use
those beautifiers with whatever event carries that payload in its
PERF_SAMPLE_RAW area (Arnaldo Carvalho de Melo)
- Add more wrappers for BPF functions to be used in eBPF programs, together
with examples on how to use them, for instance, a "hello, world" like
program attached to the 'openat' syscall entry tracepoint using a stdio.h
like puts() function that abstracts access to the bpf_perf_event_output
eBPF function associated with a eBPF map associated with a "bpf-output"
(PERF_COUNT_SW_BPF_OUTPUT software event) that gets what is passed into
the perf ring buffer to finally appear in the 'perf trace' output:
$ cd tools/perf/examples/bpf/
$ cat hello.c
#include <stdio.h>
int syscall_enter(openat)(void *args)
{
puts("Hello, world\n");
return 0;
}
license(GPL);
$
# perf trace -e hello.c cat /etc/passwd > /dev/null
0.000 __bpf_stdout__:Hello, world
0.033 __bpf_stdout__:Hello, world
0.358 __bpf_stdout__:Hello, world
#
- Add another example (augmented_syscalls.c) that copies the syscall tracepoint
payload + the first 64 bytes of 'openat''s 'filename' pointer parameter,
using the eBPF's probe_read, probe_read_str and perf_event_output, sending to
an eBPF map associated with a bpf-output perf event that then gets passwd to
the existing raw_syscalls:sys_enter beautifier.
The changesets were done very granularly so that we can see that payload
first processed by the generic bpf_output formatter, where we can see that the
filename is being copied, together with the raw_syscalls:sys_enter formatter,
to make sure both agree, e.g.:
# perf trace -e perf/tools/perf/examples/bpf/augmented_syscalls.c,openat cat /etc/passwd > /dev/null
0.000 ( ): __augmented_syscalls__:X?.C......................`\..................../etc/ld.so.cache..#......,....ao.k...............k......1.".........
0.006 ( ): syscalls:sys_enter_openat:dfd: CWD, filename: 0x5c600da8, flags: CLOEXEC
0.008 ( 0.005 ms): cat/31292 openat(dfd: CWD, filename: 0x5c600da8, flags: CLOEXEC) = 3
0.036 ( ): __augmented_syscalls__:X?.C.......................\..................../lib64/libc.so.6......... .\....#........?.......=.C..../.".........
0.037 ( ): syscalls:sys_enter_openat:dfd: CWD, filename: 0x5c808ce0, flags: CLOEXEC
0.039 ( 0.007 ms): cat/31292 openat(dfd: CWD, filename: 0x5c808ce0, flags: CLOEXEC) = 3
0.323 ( ): __augmented_syscalls__:X?.C.....................P....................../etc/passwd......>.C....@................>.C.....,....ao.>.C........
0.325 ( ): syscalls:sys_enter_openat:dfd: CWD, filename: 0xe8be50d6
0.327 ( 0.004 ms): cat/31292 openat(dfd: CWD, filename: 0xe8be50d6) = 3
#
The next step is to improve the beautifiers to use that filename so that we
can show it just like 'perf trace' + probe:vfs_getname (getname_flags kprobe supported
by 'perf trace' to show the pathname in syscalls like open, openat, rename, etc) and
strace does (via ptrace).
This now requires having a clang installed to turn the augmented_syscalls.c into
eBPF object to feed the kernel, in upcoming patches this need will be removed by
making 'perf trace' generate the object directly, or by linking libclang into
perf's binary, code that is already in merged.
strace's '-s strsize' will be implemented to state how many bytes we should copy,
so that a the familiar 'strace' workflow can be mimic'ed some more. Per-event
terms should also be used to state how many bytes for each pointer arg should be
copied and subsequently beautified, something like:
# perf trace -e openat/filename:16/,read/buf:256/
Infrastructure: (Konstantin Khlebnikov)
- Optimize the synthesization of maps for pre-existing threads, synthesizing
maps just for the thread group leader
- Optimize maps__fixup_overlappings()
Arch specific:
arm64: (Sean V Kelley)
- Enable JSON events for Ampere Computing eMAG processor
s/390: (Thomas Richter)
- Support auxiliary trace on 'perf report'
Cleanups:
- Drop unneeded bitmap_zero() calls (Yury Norov)

Test results:
The first ones are container (docker) based builds of tools/perf with
and without libelf support. Where clang is available, it is also used
to build perf with/without libelf, and building with LIBCLANGLLVM=1
(built-in clang) with gcc and clang when clang and its devel libraries
are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
