[PATCH v8 00/12] perf: enable compression of record mode trace to save storage space

From: Alexey Budankov
Date: Thu Mar 14 2019 - 07:27:01 EST



The patch set implements runtime trace compression (-z option) in
record mode and trace auto decompression in report and inject modes.
Streaming Zstd API [1] is used for compression and decompression of
data that come from kernel mmaped data buffers.

Usage of implemented -z,--compression_level=n option provides ~3-5x
avg. trace file size reduction on variety of tested workloads what
saves storage space on larger server systems where trace file size
can easily reach several tens or even hundreds of GiBs, especially
when profiling with dwarf-based stacks and tracing of context switches.
Default option value is 1 (fastest compression).

Implemented --mmap-flush option can be used to specify minimal size
of data chunk that is extracted from mmaped kernel buffer to store
into a trace. The option is independent from -z setting and doesn't
vary with compression level. The default option value is 1 byte what
means every time trace writing thread finds some new data in the
mmaped buffer the data is extracted, possibly compressed and written
to a trace. The option serves two purposes the first one is to increase
the compression ratio of trace data and the second one is to avoid
live-lock self tool process monitoring in system wide (-a) profiling
mode. Profiling in system wide mode with compression (-a -z) can
additionally induce data into the kernel buffers along with the data
from monitored processes. If performance data rate and volume from
the monitored processes is high then trace streaming and compression
activity in the tool is also high. It can lead to subtle live-lock
effect of endless activity when compression of single new byte from
some of mmaped kernel buffer induces the next single byte at some
mmaped buffer. So perf tool thread never stops on polling event file
descriptors. Varying data chunk size to be extracted from mmap buffers
allows avoiding live-locking self monitoring in system wide mode and
makes mmap buffers polling loop configurable.

$ tools/perf/perf record -z -e cycles -- matrix.gcc
$ tools/perf/perf record --aio -z -e cycles -- matrix.gcc
$ tools/perf/perf record -z --mmap-flush 1024 -e cycles -- matrix.gcc
$ tools/perf/perf record --aio -z --mmap-flush 1K -e cycles -- matrix.gcc

Runtime compression overhead has been measured for serial and AIO
trace writing modes when profiling matrix multiplication workload
with the following results:

-------------------------------------------------------------
| SERIAL | AIO-1 |
----|-----------------------------|-----------------------------|
|-z | OVH(x) | ratio(x) size(MiB) | OVH(x) | ratio(x) size(MiB) |
|---|--------|--------------------|--------|--------------------|
| 0 | 1,00 | 1,000 179,424 | 1,00 | 1,000 187,527 |
| 1 | 1,04 | 8,427 181,148 | 1,01 | 8,474 188,562 |
| 2 | 1,07 | 8,055 186,953 | 1,03 | 7,912 191,773 |
| 3 | 1,04 | 8,283 181,908 | 1,03 | 8,220 191,078 |
| 5 | 1,09 | 8,101 187,705 | 1,05 | 7,780 190,065 |
| 8 | 1,05 | 9,217 179,191 | 1,12 | 6,111 193,024 |
-----------------------------------------------------------------

OVH = (Execution time with -z N) / (Execution time with -z 0)

ratio - compression ratio
size - number of bytes that was compressed

size ~= trace file x ratio

See complete description of measurement conditions with details below.

Introduced compression functionality can be disabled or configured from
the command line using NO_LIBZSTD and LIBZSTD_DIR defines:

$ make -C tools/perf NO_LIBZSTD=1 clean all
$ make -C tools/perf LIBZSTD_DIR=/path/to/zstd/sources/ clean all

If your system has some version of the zstd package preinstalled then
the build system finds and uses it during the build. Auto detection
feature status is reported just before compilation starts, as usual.
If you still prefer to compile with some other version of zstd you have
capability to refer the compilation to that version using LIBZSTD_DIR
define.

See 'perf test' results below for enabled and disabled (NO_LIBZSTD=1)
feature configurations.
