perf tools: Fix kernel_start for PTI on x86 (2018-05-19 06:42:51 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Record min/max LBR cycles (>= skylake) and add 'perf annotate' TUI
hotkey to show it (c) (Jin Yao)
- Fix machine->kernel_start for PTI on x86 (Adrian Hunter)
- Make machine->env->arch always available, e.g. in 'perf top', not
just when reading that info from perf.data files (Adrian Hunter)
- Reduce the number of files read at 'perf' start, leaving information such as
cacheline size, tracefs mount point determination, max_stack, etc, to be
lazily read as tools needs then (Arnaldo Carvalho de Melo)
- Fixup BPF include and examples install messages (Arnaldo Carvalho de Melo)
- Fixup callchain addresses and symbol offsets in 'perf script', to help
correlating with objdump output (Sandipan Das)
Signed-off-by: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Adrian Hunter (2):
perf machine: Add machine__is() to identify machine arch
perf tools: Fix kernel_start for PTI on x86
Arnaldo Carvalho de Melo (12):
perf config: Call perf_config__init() lazily
tools lib api: The tracing_mnt variable doesn't need to be global
tools lib api: Unexport 'tracing_path' variable
tools lib api fs tracing_path: Introduce get/put_events_file() helpers
perf tools: Reuse the path to the tracepoint /events/ directory
perf parse-events: Use get/put_events_file()
tools lib api fs tracing_path: Introduce opendir() method
tools lib api fs tracing_path: Make tracing_events_path private
tools include compiler-gcc: Add __pure attribute helper

Jin Yao (2):
perf annotate: Record the min/max cycles
perf annotate: Create hotkey 'c' to show min/max cycles
Sandipan Das (2):
perf script: Show virtual addresses instead of offsets
perf script: Show symbol offsets by default

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.
