Subject: [PATCH v3 0/4] perf: Add APM X-Gene SoC Performance Monitoring Unit driver
Date: Thu, 9 Jun 2016 18:24:48 -0700 [thread overview]
Message-ID: <1465521892-31420-1-git-send-email-ttnguyen@apm.com> (raw)
In addition to the X-Gene ARM CPU performance monitoring unit (PMU), there
are PMU for the SoC system devices such as L3 cache(s), I/O bridge(s),
memory controller bridges and memory. These PMU devices are loosely
architected to follow the same model as the PMU for ARM cores.

v3:
* Remove index property use in PMU device sub nodes
v2:
* Use bitmask for event asignned counter mask pmu_dev->cntr_assign_mask
* Remove unnecessary spinlocks in perf add/del operations
* Remove unnecessary condition checks
* Enforce CPU assignment to one CPU for perf operarations
* Set the task_ctx_nr to perf_invalid_context for perf driver
* Remove irrelevant pt_rregs
* Change perf sysfs attributes to be fixed instead of dynamic
* Fix checking for an ACPI companion device instead of EFI enable
* Add documentation for config/config1 fields format and perf tool example
