perf symbols: Remove symbol_filter_t machinery

2016-09-05T14:14:50+00:00

We're not using it anymore, few users were, but we really could do
without it, simplify lots of functions by removing it.

perf evlist: Rename for_each() macros to for_each_entry()

2016-06-23T14:26:15+00:00

To match the semantics for list.h in the kernel, that are used to
implement those macros.

perf tools: Add time conversion event

2016-03-31T13:52:24+00:00

Intel PT uses the time members from the perf_event_mmap_page to convert
between TSC and perf time.

Due to a lack of foresight when Intel PT was implemented, those time
members were recorded in the (implementation dependent) AUXTRACE_INFO
event, the structure of which is generally inaccessible outside of the
Intel PT decoder.  However now the conversion between TSC and perf time
is needed when processing a jitdump file when Intel PT has been used for
tracing.

So add a user event to record the time members.  'perf record' will
synthesize the event if the information is available.  And session
processing will put a copy of the event on the session so that tools
like 'perf inject' can easily access it.

perf tools: Add cpumode to struct perf_sample

2016-03-23T15:03:07+00:00

To avoid parsing event->header.misc in many locations.

This will also allow setting perf.sample.{ip,cpumode} in a single place,
from tracepoint fields, as needed by 'perf kvm' with PPC guests, where
the guest hardware counters is not available at the host.

perf jitdump: Build only on supported archs

2016-03-10T19:33:19+00:00

Build jitdump only on architectures defined in util/genelf.h file, to avoid
breaking the build on such arches.

perf jitdump: DWARF is also needed

2016-03-09T13:29:03+00:00

While building on a Docker container for ubuntu and installing package
by package one ends up with:

    MKDIR    /tmp/build/util/
    CC       /tmp/build/util/genelf.o
  util/genelf.c:22:19: fatal error: dwarf.h: No such file or directory
   #include 
                   ^
  compilation terminated.
  mv: cannot stat '/tmp/build/util/.genelf.o.tmp': No such file or directory

Because the jitdump code needs the DWARF related development packages to
be installed. So make it dependent on that so that the build can succeed
without jitdump support.

perf jit: Move clockid validation

2016-03-08T09:11:17+00:00

Move clockid validation into jit_process() so it can later be made
conditional.

perf jit: Let jit_process() return errors

2016-03-08T09:11:17+00:00

In preparation for moving clockid validation into jit_process().

Previously a return value of zero meant the processing had been done and
non-zero meant either the processing was not done (i.e. not the jitdump
file mmap event) or an error occurred.

Change it so that zero means the processing was not done, one means the
processing was done and successful, and negative values are an error.

perf inject: Hit all DSOs for AUX data in JIT and other cases

2016-03-08T09:11:16+00:00

Currently, when injecting build ids, if there is AUX data then 'perf
inject' hits all DSOs because it is not known which DSOs the trace data
would hit.

That needs to be done for JIT injection also, and in fact there is no
reason to distinguish what kind of injection is being done.  That is,
any time there is AUX data and the HEADER_BUID_ID feature flag is set,
and the AUX data is not being processed, then hit all DSOs.  This patch
does that.
