perf intel-pt: Synthesize new power and "ptwrite" events

2017-06-30T14:48:28+00:00

Synthesize new power and ptwrite events. Power events report changes to C-state but I have also added support for the existing CBR (core-to-bus ratio) packet and included that when outputting power events. The PTWRITE packet is associated with the new "ptwrite" instruction, which is essentially just a way to stuff a 32 or 64 bit value into the PT trace. More details can be found in the patches that add documentation and in the Intel SDM.

perf intel-pt: Move code in intel_pt_synth_events() to simplify attr setting

2017-06-30T14:44:36+00:00

intel_pt_synth_events() uses the same attr structure to create each event. Move the code around a bit to simplify that. Signed-off-by: Adrian Hunter Cc: Andi Kleen Link: http://lkml.kernel.org/r/1495786658-18063-33-git-send-email-adrian.hunter@intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf intel-pt: Fix transactions_sample_type

2017-06-21T14:35:52+00:00

'transactions_sample_type' is needed to correctly inject transactions samples but it was not being set. Set it from the event sample type.

perf intel-pt: Remove redundant initial_skip checks

2017-06-21T14:35:51+00:00

'initial_skip' is checked inside the sample synthesis functions which means it is actually being done twice for 'instructions' and 'transactions' samples. Remove the redundant checks.
