Revert "perf tools: event.h needs asm/perf_regs.h"

2016-07-25T14:58:56+00:00

This reverts commit e083a21fcac9311ca425e600a15332f4792c56cc.

Not needed at all, tools/perf/util/perf_regs.h, included via:

  #include "perf_regs.h"

Should have a definition for PERF_REGS_MAX, and since this is dependent
on HAVE_PERF_REGS_SUPPORT, fixes the build on powerpc, noticed by trying
to cross compile this from ubuntu16.04 with a locally build libz &
elfutils pair, since those are not available in multilib packages.

perf tools: event.h needs asm/perf_regs.h

2016-07-12T18:20:31+00:00

As it uses PERF_REGS_MAX, fix it.

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 thread: Rename perf_event__preprocess_sample_addr to thread__resolve

2016-03-23T15:03:08+00:00

Since none of the perf_event fields are used anymore, just the
perf_sample ones, and since this resolves to (map, symbol) from data
structures within struct thread, rename it to thread__resolve and make
the argument ordering similar to the one in machine__resolve().

perf machine: Rename perf_event__preprocess_sample to machine__resolve

2016-03-23T15:03:08+00:00

Since we only deal with fields in the passed struct perf_sample move
this method to struct machine, that is where the perf_sample fields
will be resolved to a struct addr_location, i.e. thread, map, symbol,
etc.

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 tools: Add event_update event name type

2015-12-17T18:12:46+00:00

Adding name type 'event update' event, that stores/transfer events name.
Event's name is stored within perf.data's EVENT_DESC feature, but we
don't have it if we get the report data from pipe.
