Subject: [PATCH v6 0/2] drivers: perf: Add Marvell CN10K LLC-TAD pmu driver
Date: Mon, 18 Oct 2021 21:00:55 +0530	[thread overview]
Message-ID: <20211018153057.23217-1-bbudiredla@marvell.com> (raw)

This series introduces performance monitor driver to Last-level-cache
tag-and-data (LLC-TAD) PMU which is an intergral part of Marvell CN10K SoCs.
The configuration and functionality of the TAD PMU is covered in patch 1.
The device tree bindings are dealt in patch 2.

v6:
 - add COMPILE_TEST dependency (Bharat Bhushan)
 - replace sprintf with sysfs_emit (Bharat Bhushan)

v5:
 - add prefix, type, description for vendor specific properties
   in DT bindings (Rob Herring)

v4:
 - rebased on kernel v5.14-rc7
 - eliminate yamllint errors (Rob Herring) 

v3:
 - rebased on kernel v5.14-rc5
 - disable sampling events via PERF_PMU_CAP_NO_INTERRUPT (Will Deacon)
 - convert tad pmu bindings to schema (Will Deacon)
 - replace tighter semantics with *_relaxed() accesses (Will Deacon)
 - use PMU_EVENT_ATTR_ID generic macro (Will Deacon)
 - allow cleanup of allocations through devm_kcalloc() (Will Deacon)

v2:
 - rebased on kernel v5.13-rc3

    bindings
