perf bpf: Return NULL when RB tree lookup fails in perf_env__find_btf() (2019-04-17 14:30:23 -0300)
----------------------------------------------------------------
perf/urgent fixes:
perf top:
Jiri Olsa:
- Fix 'perf top --pid', it needs PERF_SAMPLE_TIME since we switched to using
a different thread to sort the events and then even for just a single
thread we now need timestamps.
BPF:
Jiri Olsa:
- Fix bpf_prog and btf lookup functions failure path to to properly return
NULL.
- Fix side band thread draining, used to process PERF_RECORD_BPF_EVENT
metadata records.
core:
Jiri Olsa:
- Fix map lookup by name to get a refcount when the name is already in
the tree. Found
Song Liu:
- Fix __map__is_kmodule() by taking into account recently added BPF
maps.
UAPI:
Arnaldo Carvalho de Melo:
- Sync sound/asound.h copy

Test results:
The first ones are container 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.

From: Jiri Olsa <jolsa@kernel.org>
Bastian reported broken 'perf top -p PID' command, it won't display any
data.
The problem is that for -p option we monitor single thread, so we don't
enable time in samples, because it's not needed.
However since commit 16c66bc167cc we use ordered queues to stash data
plus later commits added logic for dropping samples in case there's big
load and we don't keep up. All this needs timestamp for sample. Enabling
it unconditionally for perf top.

As reported by Jiri Olsa in:
"[BUG] perf: intel_pt won't display kernel function"
https://lore.kernel.org/lkml/20190403143738.GB32001@krava
Recent changes to support PERF_RECORD_KSYMBOL and PERF_RECORD_BPF_EVENT
broke --kallsyms option. This is because it broke test __map__is_kmodule.
This patch fixes this by adding check for bpf program, so that these maps
are not mistaken as kernel modules.

By calling maps__insert() we assume to get 2 references on the map,
which we relese within maps__remove call.
However if there's already same map name, we currently don't bump the
reference and can crash, like:

perf evsel: Use hweight64() instead of hweight_long(attr.sample_regs_user) (2019-04-10 10:25:28 -0300)
----------------------------------------------------------------
perf/urgent fixes:
core:
Mao Han:
- Use hweight64() instead of hweight_long(attr.sample_regs_user) when parsing
samples, this is what the kernel uses and fixes de problem in 32-bit
architectures such as C-SKY that have more than 32 registers that can come
in a sample.
perf stat:
Jiri Olsa:
- Disable DIR_FORMAT feature for 'perf stat record', fixing an assert()
failure.
Intel PT:
Adrian Hunter:
- Fix use of parent_id in calls_view in export-to-sqlite.py.
BPF:
Gustavo A. R. Silva:
- Fix lock/unlock imbalances when processing BPF/BTF info, found by the
coverity tool.
libtraceevent:
Rikard Falkeborn:
- Fix missing equality check for strcmp(), detected by the cppcheck tool.

Test results:
The first ones are container 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.

for you to fetch changes up to 21e6dfe04861c2c1b529f2759850bc62a80ca050:
perf evsel: Use hweight64() instead of hweight_long(attr.sample_regs_user) (2019-04-10 10:25:28 -0300)
----------------------------------------------------------------
perf/urgent fixes:
core:
Mao Han:
- Use hweight64() instead of hweight_long(attr.sample_regs_user) when parsing
samples, this is what the kernel uses and fixes de problem in 32-bit
architectures such as C-SKY that have more than 32 registers that can come
in a sample.
perf stat:
Jiri Olsa:
- Disable DIR_FORMAT feature for 'perf stat record', fixing an assert()
failure.
Intel PT:
Adrian Hunter:
- Fix use of parent_id in calls_view in export-to-sqlite.py.
BPF:
Gustavo A. R. Silva:
- Fix lock/unlock imbalances when processing BPF/BTF info, found by the
coverity tool.
libtraceevent:
Rikard Falkeborn:
- Fix missing equality check for strcmp(), detected by the cppcheck tool.

Test results:
The first ones are container 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.

Test results:
The first ones are container 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.

Hi Ingo,
Please consider pulling, more to come as I process the backlog
from being away for LPC.

perf tools beauty ioctl: Support new ISO7816 commands (2018-11-19 12:38:50 -0800)
----------------------------------------------------------------
perf/urgent fixes:
- Update kernel ABI headers, one of them lead to a small change in
the ioctl 'cmd' beautifier in 'perf trace' to support the new ISO7816
commands. (Arnaldo Carvalho de Melo)
- Restore proper cwd on return from mnt namespace (Jiri Olsa)
- Add feature check for the get_current_dir_name() function used in the
namespace fix from Jiri, that is not available in systems such as
Alpine Linux, which uses the musl libc (Arnaldo Carvalho de Melo)
- Fix crash in 'perf record' when synthesizing the unit for events such
as 'cpu-clock' (Jiri Olsa)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (5):
tools build feature: Check if get_current_dir_name() is available
tools headers uapi: Synchronize i915_drm.h
tools arch x86: Update tools's copy of cpufeatures.h
tools uapi asm-generic: Synchronize ioctls.h
perf tools beauty ioctl: Support new ISO7816 commands

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.

perf tools: Fix maps__find_symbol_by_name() (2018-09-11 14:12:51 -0300)
----------------------------------------------------------------
perf/urgent fixes:
- Fix finding a symbol by name when multiple maps use the same backing DSO,
so we must first see if that symbol name is in the DSO, then see if it is
inside the range of addresses for that specific map (Adrian Hunter)
- Update the tools copies of UAPI headers, which silences the warnings
emitted when building the tools and in some cases, like for the new
KVM ioctls, results in 'perf trace' being able to translate that
ioctl number to a string (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 alpine ones are failing due to a XSI/POSIX/GNU disagreement on how
strerror_r() should be implemented, a fix is in the works to make libbpf to use
the str_error_r() that tools/perf/ has been using to work on libraries such as
MUSL, that Alpine Linux uses. This problem was not introduced by any patch in
this series.

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.

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.
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.
