Subject[GIT PULL 00/24] perf/urgent improvements and fixes
Date
Hi Ingo,

Please consider pulling, next ones should be concentrating just
on bug fixes, been busy with some, so some were left in the queue,
flushing them now.

- Arnaldo

Test results at the end of this message, as usual.

The following changes since commit 28fa741c27e6d57f6bf594ba3c444ce79e671e09:

perf intel-pt/bts: Calculate cpumode for synthesized samples (2018-10-31 12:56:26 -0300)

----------------------------------------------------------------
perf/urgent improvements and fixes:

- Fixes dealing with the removal of the fallback to looking up samples
marked as userspace in the kernel maps, done recently:

- For intel-pt, that was setting the synthesized header misc field
as PERF_RECORD_MISC_USER, depending thus on the fallback to take
place, now it sets as USER or KERNEL according to x86 specific
knowledge. Also now it inserts the PERF_CONTEXT_{USER,KERNEL} into
the PERF_SAMPLE_CALLCHAINs it synthesizes from hw traces (Adrian Hunter)

- Similar fixes for the cs-etm ARM HW trace code, that used the Intel PT
model as a starting point (Leo Yan)

- For the "caller" callchain order, where the callchain returned by the
kernel was simply reversed without taking into account the
PERF_CONTEXT_{USER,KERNEL,etc} markers from where to define if an entry
was for kernel or userspace, working just because the map lookup fallback
was in place (David S. Miller)

- Allow for selecting if 'overwrite' mode should be used in 'perf top' and
make the default for it not to be used. This is due to problems with the
current implementation where the pausing used ends up making 'perf top'
miss PERF_RECORD_{MMAP,FORK,EXEC,etc} events, which with short lifetime
threads workloads leads quickly to many "unknown" maps (and thus symbols)
to appear in the UI. Workloads with long thread lifetimes and with few
metadata events can still use --overwrite to take advantage of the
overwrite mode (Arnaldo Carvalho de Melo)

- Start 'perf top''s display thread earlier, so that the screen doesn't
remain blank for too long at tool start (David S. Miller)

- Don't clone maps from parent when synthesizing forks, to avoid the inevitable
flurry of overlapping maps as we process the synthesized MMAP2 events that get
delivered shortly thereafter. (David S. Miller)

- Take pgoff into account when reporting elf to libdwfl, now the unwinding
results are the same with elfutils's libdwfl and libunwind (Milian Wolff)

- Update lotsa kernel ABI headers (Arnaldo Carvalho de Melo)

- 'perf trace' syscall arg beautification improvements to allow for
handling args such as mount's 'flags', where maks have to be ignored
before considering what is left, that, if only zeroes, is suppressed
like other args without such masks (Arnaldo Carvalho de Melo)

- Beautify mount's 'source' and 'flags' args (Arnaldo Carvalho de Melo)

- Generate mmap's flags bit constants from linux/mman.h and all the
arch specific mman.h files, so that no changes in the main 'perf trace'
source files is required when new flags get added (Arnaldo Carvalho de Melo)

- Consider syscall aliases, so that 'perf trace -e umount' works and we don't
have to use 'umount2' (that works as well, just not required) (Arnaldo Carvalho de Melo)

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.

The failures are minor and will be fixed soon.

This one is related to smp_load_{acquire,release} expansions in this specific
gcc version, reported to Daniel Borkmann

64 3.48 ubuntu:18.04-x-riscv64 : FAIL riscv64-linux-gnu-gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0

These two need mman.h files added to its directories in tools/arch/, will fix later.

66 3.84 ubuntu:18.04-x-sh4 : FAIL sh4-linux-gnu-gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0

Needs to normalize sh4 -> sh so that it finds
tools/arch/sh/include/uapi/asm/mman.h.
