[PATCH v6 0/7] arm64: perf: Broadcom Vulcan PMU support

[PATCH v6 0/7] arm64: perf: Broadcom Vulcan PMU support

[Ashok Kumar]

Cleaned up event naming convention as per ARM ARM.

Added macros for complete ARMv8 recommended implementation defined events.

changed pmu register access to make use of read/write_sys_reg.

Common architectural and micro-architectural events which are exported to /sys
are now filtered using PMCEIDn_EL0

Added support for Broadcom Vulcan PMU.

changes since v5 [5]:
 Incorporated the following review comments from Mark.
 * Folded armv8pmu_probe_num_events and armv8pmu_read_common_events_bitmap.
 * Changed format string in event number print from 0x%02llx to 0x%03llx
 * Added ARM ARM doc number in commit logs wherever referenced.
 * Fixed sysreg.h order in perf_event.c

changes since v4 [4]:
 * Used read/write_sys_reg for pmu register access as per Suzuki's review 
   comment from v2.

changes since v3 [3]:
 * Changed the order of patchset to match devicetree submission guidelines.
 * Rebased on 4.6-rc3

changes since v2 [2]:
 * Changed event filtering mechanism to use is_visible function pointer
   of attribute_group instead of copying to a new events attribute 
   structure as per Mark's review comments.

changes since v1 [1]:
 Incorporated the following review comments from Will.
 * cleaned up event naming convention as per ARM ARM
 * Filtered common events based on PMCEIDn_EL0
 * Removed exposing implementation defined events to /sys.

[PATCH v6 3/7] arm64/perf: Changed events naming as per the ARM ARM

[Ashok Kumar]

changed all the common events name definition as per the document
ARM DDI 0487A.g

SoC specific event names follow the general naming style in
the file and doesn't reflect any document.
changed ARMV8_A53_PERFCTR_PREFETCH_LINEFILL to
ARMV8_A53_PERFCTR_PREF_LINEFILL to match with other SoC specific
event names which use _PREF_ style.

corrected typo l21 to l2i.

[PATCH v6 5/7] arm64/perf: Access pmu register using <read/write>_sys_reg

[Ashok Kumar]

changed pmu register access to make use of <read/write>_sys_reg
from sysreg.h instead of accessing them directly.

[PATCH v6 6/7] arm64/perf: Filter common events based on PMCEIDn_EL0

[Ashok Kumar]

The complete common architectural and micro-architectural
event number structure is filtered based on PMCEIDn_EL0 and
exposed to /sys using is_visibile function pointer in events
attribute_group.
To filter the events in is_visible function, pmceid based bitmap
is stored in arm_pmu structure and the id field from
perf_pmu_events_attr is used to check against the bitmap.

The function which derives event bitmap from PMCEIDn_EL0 is
executed in the cpus, which has the pmu being initialized,
for heterogeneous pmu support.

Broadcom Vulcan uses ARMv8 PMUv3 and supports most of
the ARMv8 recommended implementation defined events.

Added Vulcan events mapping for perf and perf_cache map.

Are we happy with "brcm" being the exposed userspace name? It might be
better to have this as "armv8_broadcom_vulcan".

I'll leave that to you and Will. Either way:

Broadcom uses "brcm" as the vendor prefix in device trees, and the
cpu's compatible string is "brcm,vulcan", so this should be ok.

It looks like the A53 and A57 entries have established a convention of
calling the PMU  "armv8_<cpuname>". Otherwise, something very close
to the PMU's OF compatible string would have been better here.

This doesn't apply on top of -rc1 + the first four patches in your series.

... the kvm changes, which we merged for -rc2. Sorry for the noise, I'll
base this on -rc3 (to match the for-next/core branch).
