The patches define metrics and metric groups for computation by "perf" for
POWER8 processors.
Paul Clarke (4):
[powerpc] perf vendor events: Add JSON metrics for POWER8 1/4
[powerpc] perf vendor events: Add JSON metrics for POWER8 2/4
[powerpc] perf vendor events: Add JSON metrics for POWER8 3/4
[powerpc] perf vendor events: Add JSON metrics for POWER8 4/4
v2:
The content of these patches was sent previously, to LKML and linux-perf-users,
but never showed up at linux-perf-users, so I split it into smaller patches
and am resending.

POWER8 metrics not well publicized. Some are here:
https://www.ibm.com/support/knowledgecenter/en/SSFK5S_2.2.0/com.ibm.cluster.pedev.v2r2.pedev100.doc/bl7ug_derivedmetricspower8.htm
This patch is for metric groups:
- cpi_breakdown
- estimated_dcache_miss_cpi

POWER8 metrics not well publicized. Some are here:
https://www.ibm.com/support/knowledgecenter/en/SSFK5S_2.2.0/com.ibm.cluster.pedev.v2r2.pedev100.doc/bl7ug_derivedmetricspower8.htm
This patch is for metric groups:
- dl1_reloads_percent_per_inst
- dl1_reloads_percent_per_ref
- instruction_misses_percent_per_inst
- l2_stats
- lsu_rejects
- memory
- pteg_reloads_percent_per_inst
- pteg_reloads_percent_per_ref

POWER8 metrics not well publicized. Some are here:
https://www.ibm.com/support/knowledgecenter/en/SSFK5S_2.2.0/com.ibm.cluster.pedev.v2r2.pedev100.doc/bl7ug_derivedmetricspower8.htm
This patch is for metric groups:
- branch_prediction
- latency
- bus_stats
- instruction_mix
- instruction_stats_percent_per_ref

POWER8 metrics not well publicized. Some are here:
https://www.ibm.com/support/knowledgecenter/en/SSFK5S_2.2.0/com.ibm.cluster.pedev.v2r2.pedev100.doc/bl7ug_derivedmetricspower8.htm
This patch is for metric groups:
- translation
- general
and other metrics not in a metric group.

perf vendor events power8: Cpi_breakdown & estimated_dcache_miss_cpi metrics
POWER8 metrics are not well publicized.
Some are here:
https://www.ibm.com/support/knowledgecenter/en/SSFK5S_2.2.0/com.ibm.cluster.pedev.v2r2.pedev100.doc/bl7ug_derivedmetricspower8.htm
This patch is for metric groups:
- cpi_breakdown
- estimated_dcache_miss_cpi

perf vendor events power8: Dl1_reload, instruction_misses, l2_stats, lsu_rejects, memory & pteg_reloads metrics
POWER8 metrics are not well publicized.
Some are here:
https://www.ibm.com/support/knowledgecenter/en/SSFK5S_2.2.0/com.ibm.cluster.pedev.v2r2.pedev100.doc/bl7ug_derivedmetricspower8.htm
This patch is for metric groups:
- dl1_reloads_percent_per_inst
- dl1_reloads_percent_per_ref
- instruction_misses_percent_per_inst
- l2_stats
- lsu_rejects
- memory
- pteg_reloads_percent_per_inst
- pteg_reloads_percent_per_ref

perf vendor events power8: Branch_prediction, latency, bus_stats, instruction_mix & instruction_stats metrics
POWER8 metrics are not well publicized. Some are here:
https://www.ibm.com/support/knowledgecenter/en/SSFK5S_2.2.0/com.ibm.cluster.pedev.v2r2.pedev100.doc/bl7ug_derivedmetricspower8.htm
This patch is for metric groups:
- branch_prediction
- latency
- bus_stats
- instruction_mix
- instruction_stats_percent_per_ref

perf vendor events power8: Translaton & general metrics
POWER8 metrics are not well publicized.
Some are here:
https://www.ibm.com/support/knowledgecenter/en/SSFK5S_2.2.0/com.ibm.cluster.pedev.v2r2.pedev100.doc/bl7ug_derivedmetricspower8.htm
This patch is for metric groups:
- translation
- general
and other metrics not in a metric group.
