perf script: Show hw-cache events (2018-06-08 13:41:30 -0300)
----------------------------------------------------------------
perf/urgent fixes and improvements:
perf stat:
. Add --interval-clear option, to provide a 'watch' like printing (Jiri Olsa)
. Fix metric column header display alignment (Jiri Olsa)
. Improve error messages for default attributes, providing better output
for error in command lines such as:
$ perf stat -T
Cannot set up transaction events
event syntax error: '..cycles,cpu/cycles-t/,cpu/tx-start/,cpu/el-start/,cpu/cycles-ct/}'
\___ unknown term
Where the "event syntax error" line now appears (Jiri Olsa)
perf script:
. Show hw-cache events too (Seeteena Thoufeek)
perf c2c:
. Fix data dependency problem in layout of 'struct c2c_hist_entry', where
its member 'struct hist_entry' must be at the end because it has a ZLA
as its last member, that gets space when handling callchains (Jiri Olsa)
Core:
- We cannot assume that a 'struct perf_evsel' is to be obtained from a
container_of operation on a 'struct hists' as there are tools, such as
'perf c2c' that uses 'struct hist' instances without having them in
container structs that also have 'struct perf_evsel' in a particular
layout, so provide a different way of figuring out if a 'struct hists'
and 'struct hist_entry' have callchains (Arnaldo Carvalho de Melo)
- Fix error index in the PMU event parser, so that error messages can
point to the problematic token (Jiri Olsa)
Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (4):
perf hists: Save the callchain_size in struct hist_entry
perf hists: Make hist_entry__has_callchains() work with 'perf c2c'
perf hists browser gtk: Use hist_entry__has_callchains()
perf hists: Reimplement hists__has_callchains()
Jiri Olsa (7):
perf tools: Fix error index for pmu event parser
perf stat: Add --interval-clear option
perf stat: Use only color_fprintf call in print_metric_only
perf stat: Fix metric column header display alignment
perf stat: Allow to specify specific metric column len
perf stat: Add event parsing error handling to add_default_attributes
perf c2c: Keep struct hist_entry at the end of struct c2c_hist_entry
Seeteena Thoufeek (1):

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.
