[PATCH v10 00/10] lib/pmu: cleanups and trace integration

[Tomasz Duszynski]

This series does some cleanup and refactoring around the rc1 code like: trimming unused headers,
switching to callbacks for per-arch handling, and adding trace support. It also re-enables existing
base test to help catch reported issues on some architectures.

v10:
- fix build without ALLOW_EXPERIMENTAL_API
- move rte_pmu_tread_read() registration to avoid MSVC linker issues
v9:
- properly rebase patch integrating pmu and trace
v8:
- export __rte_pmu_trace_read from library itself to avoid build issues
  with msvc linker
v7:
- change test return value
v6:
- add more logs to functional test
- skip test in case of setup failure, user must make sure
  system is properly configured to get valid results
v5:
- add missing patch that quiesces chincs check
v4:
- change fast test so that it won't fail on misconfigured system
- fix compilation on windows
v3:
- do not export __rte_pmu_trace_read because that breaks compilation
  on windows - script generating map files does not handle conditional
  compilation
- skip testing if paranoia is at wrong level
v2:
- explicitly check against NULL
- make pmu lib optional by checking if dpdk config has RTE_LIB_PMU

Tomasz Duszynski (10):
  trace: change scope of conditional block
  lib/pmu: fix build error if ALLOW_EXPERIMENAL_API is undefined
  lib/pmu: quiesce rte_pmu_read deprecation warning in chkincs
  lib/pmu: export only necessary arch headers
  lib/pmu: reimplement per-arch ops as callbacks
  lib/pmu: do not try enabling perf counter access on arm64
  lib/pmu: use build system defined RTE_LIB_PMU macro
  test/pmu: enable test
  trace: add PMU
  lib/pmu: fix out-of-bound access
