  perf buildid-cache: Don't skip 16-byte build-ids (2021-02-18 16:41:40 -0300)

----------------------------------------------------------------
New features:

- Support instruction latency in 'perf report', with both memory latency
  (weight) and instruction latency information, users can locate expensive load
  instructions and understand time spent in different stages.

- Extend 'perf c2c' to display the number of loads which were blocked by data
  or address conflict.

- Add 'perf stat' support for L2 topdown events in systems such as Intel's
  Sapphire rapids server.

- Add support for PERF_SAMPLE_CODE_PAGE_SIZE in various tools, as a sort key, for instance:

    perf report --stdio --sort=comm,symbol,code_page_size

- New 'perf daemon' command to run long running sessions while providing a way to control
  the enablement of events without restarting a traditional 'perf record' session.

- Enable counting events for BPF programs in 'perf stat' just like for other
  targets (tid, cgroup, cpu, etc), e.g.:

      # perf stat -e ref-cycles,cycles -b 254 -I 1000
         1.487903822            115,200      ref-cycles
         1.487903822             86,012      cycles
         2.489147029             80,560      ref-cycles
         2.489147029             73,784      cycles
      ^C#

  The example above counts 'cycles' and 'ref-cycles' of BPF program of id 254.
  It is similar to bpftool-prog-profile command, but more flexible.

- Support the new layout for PERF_RECORD_MMAP2 to carry the DSO build-id using infrastructure
  generalised from the eBPF subsystem, removing the need for traversing the perf.data file
  to collect build-ids at the end of 'perf record' sessions and helping with long running
  sessions where binaries can get replaced in updates, leading to possible mis-resolution
  of symbols.

- Support filtering by hex address in 'perf script'.

- Support DSO filter in 'perf script', like in other perf tools.

- Add namespaces support to 'perf inject'

- Add support for SDT (Dtrace Style Markers) events on ARM64.

perf record:

- Fix handling of eventfd() when draining a buffer in 'perf record'.

- Improvements to the generation of metadata events for pre-existing threads (mmaps, comm, etc),
  speeding up the work done at the start of system wide or per CPU 'perf record' sessions.

Hardware tracing:

- Initial support for tracing KVM with Intel PT.

- Intel PT fixes for IPC

- Support Intel PT PSB (synchronization packets) events.

- Automatically group aux-output events to overcome --filter syntax.

- Enable PERF_SAMPLE_DATA_SRC on ARMs SPE.

- Update ARM's CoreSight hardware tracing OpenCSD library to v1.0.0.

perf annotate TUI:

- Fix handling of 'k' ("show line number") hotkey

- Fix jump parsing for C++ code.

perf probe:

- Add protection to avoid endless loop.

cgroups:

- Avoid reading cgroup mountpoint multiple times, caching it.

- Fix handling of cgroup v1/v2 in mixed hierarchy.

Symbol resolving:

- Add OCaml symbol demangling.

- Further fixes for handling PE executables when using perf with Wine and .exe/.dll files.

- Fix 'perf unwind' DSO handling.

- Resolve symbols against debug file first, to deal with artifacts related to LTO.

- Fix gap between kernel end and module start on powerpc.

Reporting tools:

- The DSO filter shouldn't show samples in unresolved maps.

- Improve debuginfod support in various tools.

build ids:

- Fix 16-byte build ids in 'perf buildid-cache', add a 'perf test' entry for that case.

perf test:

- Support for PERF_SAMPLE_WEIGHT_STRUCT.

- Add test case for PERF_SAMPLE_CODE_PAGE_SIZE.

- Shell based tests for 'perf daemon's commands ('start', 'stop, 'reconfig', 'list', etc).

- ARM cs-etm 'perf test' fixes.

- Add parse-metric memory bandwidth testcase.

Compiler related:

- Fix 'perf probe' kretprobe issue caused by gcc 11 bug when used with -fpatchable-function-entry.

- Fix ARM64 build with gcc 11's -Wformat-overflow.

- Fix unaligned access in sample parsing test.

- Fix printf conversion specifier for IP addresses on arm64, s390 and powerpc.

Arch specific:

- Support exposing Performance Monitor Counter SPRs as part of extended regs on powerpc.

- Add JSON 'perf stat' metrics for ARM64's imx8mp, imx8mq and imx8mn DDR, fix imx8mm ones.

- Fix common and uarch events for ARM64's A76 and Ampere eMag

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,

I notice that "perf test" when run without root priviledges now hangs at 
the daemon test - is this expected behaviour? Can we skip and warn the 
user instead?

I'm checking acme perf/core today.

Thanks

   Linux 5.11 (2021-02-14 14:32:24 -0800)

are available in the Git repository at:

   git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git

   perf buildid-cache: Don't skip 16-byte build-ids (2021-02-18 16:41:40 
-0300)

----------------------------------------------------------------
New features:

- Support instruction latency in 'perf report', with both memory latency
   (weight) and instruction latency information, users can locate 
expensive load
   instructions and understand time spent in different stages.

- Extend 'perf c2c' to display the number of loads which were blocked by 
data
   or address conflict.

- Add 'perf stat' support for L2 topdown events in systems such as Intel's
   Sapphire rapids server.

- Add support for PERF_SAMPLE_CODE_PAGE_SIZE in various tools, as a sort 
key, for instance:

     perf report --stdio --sort=comm,symbol,code_page_size

- New 'perf daemon' command to run long running sessions while providing 
a way to control
   the enablement of events without restarting a traditional 'perf 
record' session.

- Enable counting events for BPF programs in 'perf stat' just like for other
   targets (tid, cgroup, cpu, etc), e.g.:

       # perf stat -e ref-cycles,cycles -b 254 -I 1000
          1.487903822            115,200      ref-cycles
          1.487903822             86,012      cycles
          2.489147029             80,560      ref-cycles
          2.489147029             73,784      cycles
       ^C#

   The example above counts 'cycles' and 'ref-cycles' of BPF program of 
id 254.
   It is similar to bpftool-prog-profile command, but more flexible.

- Support the new layout for PERF_RECORD_MMAP2 to carry the DSO build-id 
using infrastructure
   generalised from the eBPF subsystem, removing the need for traversing 
the perf.data file
   to collect build-ids at the end of 'perf record' sessions and helping 
with long running
   sessions where binaries can get replaced in updates, leading to 
possible mis-resolution
   of symbols.

- Support filtering by hex address in 'perf script'.

- Support DSO filter in 'perf script', like in other perf tools.

- Add namespaces support to 'perf inject'

- Add support for SDT (Dtrace Style Markers) events on ARM64.

perf record:

- Fix handling of eventfd() when draining a buffer in 'perf record'.

- Improvements to the generation of metadata events for pre-existing 
threads (mmaps, comm, etc),
   speeding up the work done at the start of system wide or per CPU 
'perf record' sessions.

Hardware tracing:

- Initial support for tracing KVM with Intel PT.

- Intel PT fixes for IPC

- Support Intel PT PSB (synchronization packets) events.

- Automatically group aux-output events to overcome --filter syntax.

- Enable PERF_SAMPLE_DATA_SRC on ARMs SPE.

- Update ARM's CoreSight hardware tracing OpenCSD library to v1.0.0.

perf annotate TUI:

- Fix handling of 'k' ("show line number") hotkey

- Fix jump parsing for C++ code.

perf probe:

- Add protection to avoid endless loop.

cgroups:

- Avoid reading cgroup mountpoint multiple times, caching it.

- Fix handling of cgroup v1/v2 in mixed hierarchy.

Symbol resolving:

- Add OCaml symbol demangling.

- Further fixes for handling PE executables when using perf with Wine 
and .exe/.dll files.

- Fix 'perf unwind' DSO handling.

- Resolve symbols against debug file first, to deal with artifacts 
related to LTO.

- Fix gap between kernel end and module start on powerpc.

Reporting tools:

- The DSO filter shouldn't show samples in unresolved maps.

- Improve debuginfod support in various tools.

build ids:

- Fix 16-byte build ids in 'perf buildid-cache', add a 'perf test' entry 
for that case.

perf test:

- Support for PERF_SAMPLE_WEIGHT_STRUCT.

- Add test case for PERF_SAMPLE_CODE_PAGE_SIZE.

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.

> The first ones are container based builds of tools/perf with and without

> 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
