[Qemu-devel] [kvm-unit-tests PATCH v14 0/5] ARM PMU tests

[Wei Huang]

Changes from v13:
* Rename cp15.h to sysreg.h for ARMv7 and add a new file sysreg.h for ARMv8
* Add macros for read_sysreg() and write_sysreg(). CP15 registers can be
  defined with __ACCESS_CP15() or __ACCESS_CP15_64(). sysreg.h (ARMv8) was
  from Drew's GIC testing code, which can be leveraged when his GIC testing
  code is imported.
* Rewrite PMU testing code based on new macros. All get_xxx() and set_xxx()
  functions are defined in pmu.c based on read_sysreg() and write_sysreg().
  So the code parsing tool, like cscope, can parse them easily.
* Minor fixes inside pmu.c, printf formatting, pmu_probe() func, based on
  Andre's comments.

Note:
Current KVM code has bugs in handling PMCCFILTR write. A fix (see below) is
required for this unit testing code to work correctly under KVM mode.
