  perf build: Align the names of the build tests: (2016-01-29 17:51:04 -0300)

----------------------------------------------------------------
New features:

- Port 'perf kvm stat' to PowerPC (Hemant Kumar)

Infrastructure:

- Use the 'feature-dump' target to do the feature checks just once and then
  add code to reuse that in the tests/make makefile, speeding up the
  'make -C tools/perf build-test' target (Wang Nan)

- Reduce the number of tests the 'build-test' target do to those that don't
  pollute the source tree (Arnaldo Carvalho de Melo)

- Improve the output of the build tests a bit by aligning the name of the
  tests, more can be done to filter out uninteresting info in the output
  (Arnaldo Carvalho de Melo)

- Add perf_evlist pointer to *info_priv_size(), more prep work for
  supporting the coresight architecture (Mathieu Poirier)

- Improve the 'perf test bp_signal' test (Wang Nan)

- Check environment before starting the BPF 'perf test', so that we can just
  'Skip' older kernels instead of 'FAIL'ing them (Wang Nan)

- Fix cpumode of synthesized buildid event (Wang Nan)

[PATCH 12/16] perf kvm/{x86, s390}: Remove dependency on uapi/kvm_perf.h

[Arnaldo Carvalho de Melo]

From: Hemant Kumar <hemant@linux.vnet.ibm.com>

Its better to remove the dependency on uapi/kvm_perf.h to allow dynamic
discovery of kvm events (if its needed). To do this, some extern
variables have been introduced with which we can keep the generic
functions generic.

[PATCH 13/16] perf kvm/{x86,s390}: Remove const from kvm_events_tp

[Arnaldo Carvalho de Melo]

See http://www.infradead.org/rpr.html

From: Hemant Kumar <hemant@linux.vnet.ibm.com>

This patch removes the "const" qualifier from kvm_events_tp declaration
to account for the fact that some architectures may need to update this
variable dynamically. For instance, powerpc will need to update this
variable dynamically depending on the machine type.

[PATCH 14/16] perf kvm/powerpc: Port perf kvm stat to powerpc

[Arnaldo Carvalho de Melo]

See http://www.infradead.org/rpr.html

From: Hemant Kumar <hemant@linux.vnet.ibm.com>

perf kvm can be used to analyze guest exit reasons. This support already
exists in x86. Hence, porting it to powerpc.

 - To trace KVM events :
  perf kvm stat record
  If many guests are running, we can track for a specific guest by using
  --pid as in : perf kvm stat record --pid <pid>

 - To see the results :
  perf kvm stat report

The result shows the number of exits (from the guest context to
host/hypervisor context) grouped by their respective exit reasons with
their frequency.

Since, different powerpc machines have different KVM tracepoints, this
patch discovers the available tracepoints dynamically and accordingly
looks for them. If any single tracepoint is not present, this support
won't be enabled for reporting. To record, this will fail if any of the
events we are looking to record isn't available.  Right now, its only
supported on PowerPC Book3S_HV architectures.

To analyze the different exits, group them and present them (in a slight
descriptive way) to the user, we need a mapping between the "exit code"
(dumped in the kvm_guest_exit tracepoint data) and to its related
Interrupt vector description (exit reason). This patch adds this mapping
in book3s_hv_exits.h.

It records on two available KVM tracepoints for book3s_hv:

"kvm_hv:kvm_guest_exit" and "kvm_hv:kvm_guest_enter".

Here is a sample o/p:
 # pgrep qemu
19378
60515

2 Guests are running on the host.

 # perf kvm stat record -a
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 4.153 MB perf.data.guest (39624
samples) ]

 # perf kvm stat report -p 60515

[PATCH 15/16] perf kvm/powerpc: Add support for HCALL reasons

[Arnaldo Carvalho de Melo]

From: Hemant Kumar <hemant@linux.vnet.ibm.com>

Powerpc provides hcall events that also provides insights into guest
behaviour. Enhance perf kvm stat to record and analyze hcall events.

 - To trace hcall events :
  perf kvm stat record

 - To show the results :
  perf kvm stat report --event=hcall

The result shows the number of hypervisor calls from the guest grouped
by their respective reasons displayed with the frequency.

This patch makes use of two additional tracepoints
"kvm_hv:kvm_hcall_enter" and "kvm_hv:kvm_hcall_exit". To map the hcall
codes to their respective names, it needs a mapping. Such mapping is
added in this patch in book3s_hcalls.h.

 # pgrep qemu
A sample output :
19378
60515

2 VMs running.

 # perf kvm stat record -a
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 4.153 MB perf.data.guest (39624
samples) ]

 # perf kvm stat report -p 60515 --event=hcall

Analyze events for all VMs, all VCPUs:

    HCALL-EVENT Samples Samples% Time% MinTime MaxTime  AvgTime

          H_IPI     822  66.08% 88.10% 0.63us  11.38us 2.05us (+- 1.42%)
     H_SEND_CRQ     144  11.58%  3.77% 0.41us   0.88us 0.50us (+- 1.47%)
   H_VIO_SIGNAL     118   9.49%  2.86% 0.37us   0.83us 0.47us (+- 1.43%)

H_GET_TERM_CHAR      74   5.95%  2.23% 0.37us   1.70us 0.58us (+- 4.77%)
         H_RTAS       6   0.48%  0.85% 1.10us   9.25us 2.70us (+-48.57%)
      H_PERFMON       4   0.32%  0.12% 0.41us   0.96us 0.59us (+-20.92%)

Total Samples:1244, Total events handled time:1916.69us.

>   perf build: Align the names of the build tests: (2016-01-29 17:51:04 -0300)
> 
> ----------------------------------------------------------------
> New features:
> 
> - Port 'perf kvm stat' to PowerPC (Hemant Kumar)
> 
> Infrastructure:
> 
> - Use the 'feature-dump' target to do the feature checks just once and then
>   add code to reuse that in the tests/make makefile, speeding up the
>   'make -C tools/perf build-test' target (Wang Nan)
> 
> - Reduce the number of tests the 'build-test' target do to those that don't
>   pollute the source tree (Arnaldo Carvalho de Melo)
> 
> - Improve the output of the build tests a bit by aligning the name of the
>   tests, more can be done to filter out uninteresting info in the output
>   (Arnaldo Carvalho de Melo)
> 
> - Add perf_evlist pointer to *info_priv_size(), more prep work for
>   supporting the coresight architecture (Mathieu Poirier)
> 
> - Improve the 'perf test bp_signal' test (Wang Nan)
> 
> - Check environment before starting the BPF 'perf test', so that we can just
>   'Skip' older kernels instead of 'FAIL'ing them (Wang Nan)
> 
> - Fix cpumode of synthesized buildid event (Wang Nan)

Pulled, thanks a lot Arnaldo!
